I'm trying to sort by a column in datatables, while having the sorting disabled.
var table = $('#example').DataTable({
"order": [3,'desc'],
"ordering": false
});
Will try to be clear as possible by showcasing the issue in this example: http://live.datatables.net/focajayi/1/edit
As you can see, I'm trying to sort by Age in descending order, but it won't sort it, unless I set 'ordering' to true.
I'm aware that I can do this with hacks, or the prettiest solution that I know of so far, would be to remove the ordering attribute, and use the columnDefs instead, which seems to work as expected, but I would like to know if there's a global solution, without having to build the columnDefs data.
After a bit more research I found a close enough solution.
So what I've done, is just set the ordering to true, and then specifying it in the columnDefs.
var table = $('#example').DataTable({
"order": [3,'desc'],
"ordering": true,
"columnDefs": [{
"targets": "_all", "orderable": false
}]
});
Turns out it's possible to use the '_all' keyword to apply for all columns.
I was worried in always having to maintain the columnDefs list, but with the '_all' target it's perfect.

I just created a project based on the https://github.com/antfu/vitesse template. But I've some formatting issue.
If I ask for formating in VS Code, each "first" attribute of an html element is on the same line as the start of element, which is something I would have expected, but it raises warning:
Expected a linebreak before this attribute.eslintvue/first-attribute-linebreak
or sometimes:
Expected indentation of 2 spaces but found 4 spaces.eslintvue/html-indent
If I hit Ctrl+S, then I get no errors anymore, all the attributes(including first one) are on a new line.
Honestly, I don't really care which is kept, but how to synchronize the two of them? It jumps a lot every time I format and it's disturbing.
Thank you very much
EDIT
After #tony19's comment, I tried to set volar as default formatter. So my .vscode/settings.json looks like:
{
"cSpell.words": [
"Vitesse",
"Vite",
"unocss",
"vitest",
"vueuse",
"pinia",
"demi",
"antfu",
"iconify",
"intlify",
"vitejs",
"unplugin",
"pnpm"
],
"i18n-ally.sourceLanguage": "en",
"i18n-ally.keystyle": "nested",
"i18n-ally.localesPaths": [
"locales"
],
"i18n-ally.sortKeys": true,
"prettier.enable": false,
"editor.codeActionsOnSave": {
"source.fixAll.eslint": true
},
"files.associations": {
"*.css": "postcss"
},
"editor.formatOnSave": false,
"editor.defaultFormatter": "Vue.volar"
}
But I've still the same behavior. shift+alt+F format like this:
<div id="simple"
class="toto">
index
</div>
and when I save, it formats like this:
<div
id="simple"
class="toto"
>
index
</div>
I must admit that I'm not a big fan of having the end > on a single line but as far as the comportment is coherent I'm happy
(I also tried "editor.defaultFormatter": "dbaeumer.vscode-eslint" and "editor.defaultFormatter": "antfu.vite" without any luck.
I cannot figure out the way to solve this. Ive tried adding "table-layout:fixed" but it no longer works in dt's current version.
Thanks

I don't quite have enough information to give you a firm answer, because you don't tell us what's in your columns variable and don't give us the structure of your dataoMine array. But, it seems pretty clear from your screen shot that you have four columns of data, and also have eight columns specified. That will show all the columns and whatever background you have for the missing data columns. Presumably, your "barbershop stripes" are the page background in whatever theme you are using.
Make sure that you have the same number of columns in your data that you have in your column specification, and see if that fixes your problem.
After researching it turns out that this problem is very common. It seems there is no definitive solution but this worked for me:
add this into dt's config:
scrollX: 100%
i fixed my problem by just adding
scrollX: true
I am using jQrid version 3.8.1 with inline editing and each row in the grid has several dropdown lists to populate. When the user edits the row, I need to do an AJAX query to get the values for each of these lists. I've seen this post regarding how to do that. It appears that the dataUrl and buildSelect features are the standard answer here. There are a few issues I can't figure out though:
The row the user is editing has a value that must be passed into the dataUrl value. For example, say each row contains a field called "SpecialValue" and that for row 1, SpecialValue = 100. The dataUrl field for row 1 would be "http://my.services.com?SpecialValue=100". How do I do that?
Each row in the grid has about 10 select boxes that need to be populated. For efficiency reasons, I don't want to make 10 separate AJAX calls. It would be much better to make one call to get all the data, split it up, and fill each select box accordingly. Is that possible? I tried doing this inside onSelectRow but the grid ended up ignoring the values I put in there (I'm guessing do the ordering of the events that fire when you edit a row).
Edit:
After reading Oleg's answers and working on it more, it's clear to me that using dataUrl and buildSelect are not going to work well for me. The version of jqGrid I'm using doesn't support using dataUrl the way I would need. And even if it did I don't want to send multiple separate requests for each dropdown list.
I've decided to do one request when gridComplete fires to pull all the data needed for all dropdown lists into a single JSON structure. Then when the user selects a row to do inline editing, I will populate each list in the row from that JSON structure (the code below uses the getSelectValuesFromJSON() function for that--I don't give its definition but you can imaging it looks through the structure and gets an appropriate list of values to but in the list box).
I have a few candidate solutions but I'm not 100% happy with either one.
Solution 1:
Inside onSelectRow, I call editRow overriding the on oneditfunc to get the data out of the grid that I need. Assume that the value in Field1 is required to get the values to be put into the list in Field2.
onSelectRow: function (index, status, e) {
jQuery('#my_grid').jqGrid('editRow', index, true, function(rowId) {
var f1Val = $('#my_grid').jqGrid('getCell', index, 'Field1');
var selectVals = getSelectValuesFromJSON(f1Val); //gets data out of previously loaded JSON structure
var select = $('#my_grid').find('tr[id="' + index + '"] td[aria-describedby="my_grid_Field2"] select');
_.each(selectVals, function(selectVal) {
$(select).append($("<option></option>").attr("value", selectVal).text(selectVal));
});
});
}
This works but I'm hesitant about the line
var select = $('#my_grid').find('tr[id="' + index + '"] td[aria-describedby="my_grid_Field2"] select');
which relies on this aria-describedby attribute that I don't know much about. Seems hacky and brittle.
Solution 2:
Make use of beforeSelectRow to dynamically change the model of the Field2 column when the user selects a row.
beforeSelectRow: function(index, e) {
var f1Val = getGridCellValue('#my_grid', index, 'Field1');
var values = getSelectValuesFromJSON(f1Val); //gets data out of previously loaded JSON structure
var valStr = "";
_.each(values, function(value) {
valStr += value + ":" + value + ";"
});
jQuery('#grid_pipes').setColProp('Field2', { editoptions: { value: valStr } });
return true;
}
This also works but I'm not sure about whether or not this is really a good idea. Is it valid to dynamically change the model of a column like that? What if the user has several rows selected at the same time? Isn't there only one model for a column? What would that mean?
To answer some of Oleg's questions, the dataType has been set to a function that uses $.ajax to post data to the server. I think I read that's not the recommended approach anymore. I inherited this code so I'm not sure why it was done that way but it probably won't change unless there is a really compelling reason.
The loadonce boolean is not specified so I guess that means it defaults to false.
Here is an abbreviated version of the column model (nothing terribly out of the ordinary):
colModel: [
{ name: 'PK', index: 'PK', hidden: true, editable: true, sortable: true, search: true },
{ name: 'Field1', index: 'Field1', hidden: true, editable: true, sortable: true, search: true },
{ name: 'Field2', index: 'Field2', sortable: false, editable: true, search: false, edittype: "select", editoptions: {} },
{ name: 'Field3', index: 'Field3', sortable: false, editable: true, search: false, edittype: "select", editoptions: {} },
...
]
You don't wrote which version of jqGrid you use currently, but dataUrl can be defined as callback function with (rowid, value, name) parameters, which have to return the URL which you can build dynamically based on the information. The feature exist starting with v4.5.3 (see the line). You can use getCell, getRowData or getLocalRow inside of the callback to get the data from another columns of the row. Thus you can solve your first problem relatively easy.
You second question seems to me absolutely independent from the first one. It's better to separate such questions in different posts to allow the searching engine better to index the information and so to help other people to find it.
There are no simple way how to solve the second problem, but one can sure suggest a solution, but one have to know much more details what you do and how you do. How you start inline editing (do you use inlineNav, formatter: "actions" or you call editRow directly)? Which version of jqGrid (till version 4.7), free jqGrid or Guriddo jqGrid JS you use? How the columns with selects are defined in colModel? Which datatype you use and whether loadonce: true you use? I recommend you to post separate question with the information.
UPDATE: If you have to use old version of jqGrid then you can't generate dataUrl full dynamically, but because you need to add only SpecialValue=100" part to the URL you can follow the trick which I described in many my old answers (the first one was probably here, but the choice on property names which asked the user could be misunderstood). You can use ajaxSelectOptions.data which will define the data parameters of jQuery.ajax request. The problem only that you can define only one ajaxSelectOptions.data property. So you can add the following jqGrid option:
ajaxSelectOptions: {
data: {
SpecialValue: function () {
var rowid = $myGrid.jqGrid("getGridParam", "selrow");
return $myGrid.jqGrid("getCell", rowid, "SpecialValue");
}
}
}
($myGrid is something like $("#grid"))
UPDATED: You used unknown functions getSelectValuesFromJSON, getLookupValuesFromJSON in the updated part of your question. Both of there seems to use synchronous Ajax request which is not good. Moreover you set editoptions.value for only one Field2 instead of setting all selects.
onSelectRow: function (rowid) {
var $myGrid = $(this);
$.ajax({
url: "someUrl",
dataType: "json";
data: {
specialValue: $myGrid.jqGrid("getCell", rowid, "Field1")
},
success: function (data) {
// for example response data have format:
// { "Field2": ["v1", "v2", ...], "Field3": ["v3", "v4", ...] }
var filed, str;
for (filed in data) {
if (data.hasOwnProperty(filed)) {
str = $.map(data[filed], function (item) {
return item + ":" + item
}).join(";");
$myGrid.jqGrid("setColProp", filed, {
editoptions: {
value: str
}
});
}
}
$myGrid.jqGrid("editRow", rowid, true);
}
});
}
Nevertheless the "Solution 2" is more close to what I would recommend you. It's not really important whether to use onSelectRow or beforeSelectRow. You can make asynchronous Ajax request to the server which returns information for all select which you need. After you get the response from the server (inside of success callback) you can set editoptions.value for all selects and only then you can start editRow. In the way you will be sure that editing of the line will use row specific options in all select.
Some additional remarks. I recommend you to verify gridview: true option in the grid. Additionally I suspect that you fill the grid in not full correct way because you have hidden PK column and you use index instead of rowid as the first parameter of beforeSelectRow and onSelectRow. It's very important to understand that the current implementation of jqGrid always assign id attribute on every row (<tr> element) of the grid. So you have to provide id information in every item of input data. If you want to display the id information to the user (and so to have column in colModel with the primary key) then you should just include key: true property in the column definition. For example you can add key: true to the definition of PK column and so you will have rowid (or index in your case) with the same value like PK. It simplify many parts of code. For example jqGrid send id parameter in the editing request to the server. It's practical to have PK in the request. Moreover if you use repeatitems: false format of jsonReader the you can include id: "PK" in the jsonReader instead of having hidden PK column. It informs jqGrid to get rowid from PK. jqGrid will save PK in id attribute of <tr> and you will don't need to have additional <td style="display:none"> with the same information in the grid.
The last remark. I would strictly recommend you to update the retro version jqGrid 3.8.1 to some more recent version, for example to free jqGrid. Even if you would use no features (like Font Awesome for example) you will have performance advantages, and the look of modern web browsers will looks much better. You should understand the jqGrid 3.8.1 was tested with old (and slow jQuery 1.4.2). The version used with Internet Explorer 8 as the latest IE version (IE9 was published later in March 2011) and it's more oriented on IE6/IE7. The look in modern Chrome/Firefox/Safari can be bad. Is it what you want?
I am using the https://datatables.net/ jQuery plugin to display client side tabular data.
The data for my table is pre-sorted so I don't want the overhead of dataTables doing the first sort. I have set aaSorting to [] so that dataTables does not sort the data.
My problem is that I would like the header style to show which column the data is sorted by and when that column is sorted for it to toggle the sort order.
I tried a cheat of the following which displays the way I want but I have to click twice to change the search to descending.
dataTableOptions.fnInitComplete = function (oSettings, json) {
$table.find('th:first').addClass('sorting_asc');
};
Any suggestions would be greatly appreciated.
Thanks.
You can set the default sort direction of your target column to 'desc' by using asSort as documented here. This would sort your table in descending order on the first click. You would still to set the class of th:first to sorting_asc on init.
// Using aoColumns
$(document).ready( function() {
$('#example').dataTable( {
"aaSorting": [],
"aoColumns": [
{ "asSorting": [ "desc", "asc" ] }, // assumes you are targeting column 1
...// other columns
],
...// other configuration
} );
} );
I cannot make it to work properly.
I need on initial load to have my table sorted by 0-index column in 'desc'.
I've tried:
$(function() {
ordersTable = $('#orders').dataTable({
"sDom": "<'row'<'span6'l><'span6'f>r>t<'row'<'span6'i><'span6'p>>",
"sPaginationType": 'full_numbers',
"bDestroy": true,
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "{% url get_orders %}",
"aoColumnDefs":[
{"aTargets":[0], "asSorting": ["decs", "asc"]}
]
});
and what it does is sends "sSortDir_0 :'asc'" and displaying "asc" active after that.
How can it make it work? (without faking click on the column to resend the ajax)
Thanks
Ok, I guess I've found it: aaSorting and aaSortingFixed sets the initial sorting. (reference here)
