I have a jQuery dataTable which I use to search for a month like this:
table.column(1).search("February").draw();
I would like to pass 2 months as filter now but this does not work:
table.column(1).search(["Ferbrary", "March"]).draw();
Also, search returns an DataTables.API object as per the documentation - https://datatables.net/reference/api/search()
Is there anyway we can add 2 DataTables.API objects and invoke a draw() on the combination? I tried this and it didn't work:
filtered_table = table.column(1).search("February") + table.column(1).search("March");
filtered_table.draw();
This link jQuery DataTables filter rows based on multiple values says we can use a different function fnFilter instead of search to search multiple values using regex.
As per the suggestion in the above link, I tried these and none worked:
table.fnFilter("^February\$|^March\$", 1, true, false, false, false).draw();
table.fnFilter("February|March", 1, true, false, false, false).draw();
How do I achieve multiple value filters on the same column? Pls help!
You can use regular expressions with column().search() API method to search for multiple values in the same column.
For example:
table.column(1).search('February|March', true, false).draw();
See this example for code and demonstration.

That's similar to what I want to achieve.
I'd like my table to be responsive using the approach of reorganizing itself such that it shows each original row transposed (but also transpose the headers and duplicate them so that they label each row).
ag-Grid seems like a phenomenal library that has countless features, so I was surprised that the docs seem not to specify how to accomplish my goal.
Unfortunately this feature is not available out of the box.
This is actually a feature request which can be found here:
https://www.ag-grid.com/ag-grid-pipeline/
AG-3142 Allow the grid to change columns for rows (transpose rows), so the grid show each row as one column, and each column as a row
To achieve this, you would have to write a function yourself to transpose the rows into one column.
You can then leverage Grid API methods to update the column and row data accordingly.
I've created a simple plunker which does this based on a button click:
function onBtnClick() {
let newColumnDefs = [{ field: 'transposed_rows' }];
let newRowData = [];
gridOptions.api.forEachNode((node) => {
let nodeDataValues = Object.values(node.data);
nodeDataValues.forEach((val) => newRowData.push({ transposed_rows: val }));
});
gridOptions.api.setColumnDefs(newColumnDefs);
gridOptions.api.setRowData(newRowData);
}
Is there any possibility for excluding the row from filter.
Suppose i have 20 <tr> i want 1, 6, 11 or any number row will not be effected by the filtering. It will be always visible.
Thanks in advance....
You can try the html5-data-attributes along with yadcf html5_data , you can try omit the data-filter from certain rows
html5_data -
Required: false
Type: String
Default value: undefined
Possible values: data-filter / data-search / anything that is supported by datatables
Description: Allows to filter based on data-filter / data-search attributes of the element, read more: http://www.datatables.net/examples/advanced_init/html5-data-attributes.html
Is there support for an infinite list backed by the websql proxy? It doesn't seem so, as whether infinite is true or false, there are only 25 items in the list.
You should use ListPaging plugin in the list.
{
xclass: 'Ext.plugin.ListPaging',
autoPaging: true,
loadMoreText : 'Loading more',
noMoreRecordsText : 'loaded'
}
Please check sencha touch documentation for further info.
I was able to get this to work by modifying the Sql proxy to include total record count. More specifically, in the selectRecords method I had to change the code:
result.setTotal(count);
to a second executeSql call that queries all records. The sql statement is similar to the original one, except that (1) it does not include the LIMIT expression; and (2) the SELECT * should be SELECT COUNT(*) AS TotalCount. Then read TotalCount value from the first row of the result set, call result.setTotal(totalCount), and finally fire the callback.
I'd like to refresh my table when new item is added. I use such code:
$("#frm_create_user").submit(function() {
var formData = getFormData($("#frm_create_user"));
$.ajax({
type: "POST",
url: getApiUrl("/user"),
dataType: "json",
contentType: 'application/json',
data: JSON.stringify({user:{user_ref: formData.user_ref}}),
}).done(function(r) {
oTable.fnReloadAjax(getApiUrl("/users?sSearch=" + r.user.userid));
});
return false;
});
But for some reason, I can see two requests instead of one.
The first one is correct - http://symfony/app_dev.php/api/users?sSearch=kZoh1s23&_=1394204041433
And the second one is confusing - http://symfony/app_dev.php/api/users?sSearch=kZoh1s23&sEcho=3&iColumns=8&sColumns=&iDisplayStart=0&iDisplayLength=25&mDataProp_0=userid&mDataProp_1=user_ref&mDataProp_2=password&mDataProp_3=vpn_password&mDataProp_4=status_id&mDataProp_5=expire_account&mDataProp_6=created&mDataProp_7=&sSearch=&bRegex=false&sSearch_0=&bRegex_0=false&bSearchable_0=true&sSearch_1=&bRegex_1=false&bSearchable_1=true&sSearch_2=&bRegex_2=false&bSearchable_2=true&sSearch_3=&bRegex_3=false&bSearchable_3=true&sSearch_4=&bRegex_4=false&bSearchable_4=true&sSearch_5=&bRegex_5=false&bSearchable_5=true&sSearch_6=&bRegex_6=false&bSearchable_6=true&sSearch_7=&bRegex_7=false&bSearchable_7=true&iSortCol_0=0&sSortDir_0=asc&iSortingCols=1&bSortable_0=true&bSortable_1=false&bSortable_2=true&bSortable_3=true&bSortable_4=true&bSortable_5=true&bSortable_6=true&bSortable_7=true&_=1394204041505
If I remove fnReloadAjax() line, these two requests gone so that it looks like it is caused by fnReloadAjax()
How may I fix it to have only http://symfony/app_dev.php/api/users?sSearch=kZoh1s23&_=1394204041433 requests?
All these confusing parameters are Informations that your server sided script might need to clamp the data that has to be returned to dataTables.
Since I don't know your server sided code, I can only break up what they are good for:
&sEcho=3 //No need to react to this, it's just the result of the last ajax call
&iColumns=8 //Your table has 8 columns
&iDisplayStart=0 //You are on page 1
&iDisplayLength=25 //you want to display up to 25 entrys per page
&mDataProp_0=userid //Your first colum gets the value of [userid]
&mDataProp_1=user_ref //Your first colum gets the value of [user_ref]
&mDataProp_2=password //Your first colum gets the value of [password]
etc...
&sSearch=12345&bRegex=true//Your first column is filtered by userid 12345 and this value should be treated as a regex by your datasource
&sSearch_0=&bRegex_0=false//Your second column is not filtered and should not be treated as a regex by your datasource
etc...
&iSortCol_0=0&sSortDir_0=asc //your first column should be sorted ascending
&iSortingCols=1 //you have one column that is sortable
&bSortable_0=true //Column 0 is sortable
&bSortable_1=false //Column 1 is not sortable
etc..
Your server sided script should react to these values. In case of a mysql datasource it should set up its where clause to the filtering parameters, limit it by pagenumber and items per page, and sort according to the sortinfo.
All this is needed if you want to use the luxury features of datatables like pagination, sorting, individual column filtering, clamping ajax return values to minify serverload when working with thousands of entrys.
If you don't need that, just ignore the additional parameters in your server script and just react to the data you need. But leave them in, you might need them later:-)
Hope this helps
I am trying to get the ID under "General" from a feature item in rally. This is my query:
body = { "find" => {"_ProjectHierarchy" => projectID, "_TypeHierarchy" => "PortfolioItem/Feature"
},
"fields" => ["FormattedID","Name","State","Release","_ItemHierarchy","_TypeHierarchy","Tags"],
"hydrate" => ["_ItemHierarchy","_TypeHierarchy","Tags"],
"fetch"=>true
}
I am not able to get any value for FormattedID, I tried using "_UnformattedID" but it pulls up an entirely different value than the FormattedID. Any help would be appreciated.
LBAPI does not have FormattedID field. You are correct using _UnformattedID. It is the FormattedID without the prefix. For example, this query:
https://rally1.rallydev.com/analytics/v2.0/service/rally/workspace/1111/artifact/snapshot/query.js?find={"_ProjectHierarchy":2222,"_TypeHierarchy":"PortfolioItem/Feature","State":"Developing",_ValidFrom: {$gte: "2013-06-01TZ",$lt: "2013-09-01TZ"}},sort:{_ValidFrom:-1}}&fields=["_UnformattedID","Name","State"]&hydrate=["State"]&compress=true&pagesize:200
shows _UnformattedID that correspond to FormattedID as this screenshot shows:
I noticed your are using fields and fetch . Per LBAPI's documentation, it uses fields rather than fetch. If you want to get all fields, use fields=true
As far as the missing custom fields, make sure that the custom field value was set within the dates of the query.
Compare these almost identical queries: the first query does not return a custom field, the second query does.
Query #1:
https://rally1.rallydev.com/analytics/v2.0/service/rally/workspace/1111/artifact/snapshot/query.js?find={"_ProjectHierarchy":2222,"_TypeHierarchy":"PortfolioItem/Feature","State":"Developing",_ValidFrom: {$gte: "2013-06-01TZ",$lt: "2013-09-01TZ"}}}&fields=["_UnformattedID","Name","State","c_PiCustomField"]&hydrate=["State","c_PiCustomField"]
Query #2:
https://rally1.rallydev.com/analytics/v2.0/service/rally/workspace/11111/artifact/snapshot/query.js?find={"_ProjectHierarchy":2222,"_TypeHierarchy":"PortfolioItem/Feature","State":"Developing",__At: "current"}&fields=["_UnformattedID","Name","State","c_PiCustomField"]&hydrate=["State","c_PiCustomField"]
The first query uses time period: _ValidFrom: {$gte: "2013-06-01TZ",$lt: "2013-09-01TZ"}
The second query uses __At: "current"
Let's say I just create a new custom field on PortfolioItem. It is not possible to create a custom field on PorfolioItem/Feature, so the field is created on PI, but both queries still use "_TypeHierarchy":"PortfolioItem/Feature".
After I created this custom field, called PiCustomField, I set a value of that field for a specific Feature, F4.
The first query does not have a single snapshot that includes that field because that field did not exist in the time period we lookback. We can't change the past.
The second query returns this field for F4. It does not return it for other Features because all other Features do not have this field set.
Here is the screenshot:
