I have the below snippet of code that basically builds alot of rows in a data table. here is a demo. I am trying to use slepp to simulate a big dataset here.
//START:: show a loading message on the screen
//draw my rows
_.each(file, function(row) {
//sleep(5000)
t1.addRows(row)
});
//END:: STOP showing a loading message on the screen
and I want to be able to display to the user that it is loading.
How do I do this.
I have the below links but I cannot seem to get them to work

I want to use one of these images
I thinking of using one of these .gif files to display while loading.
SOLUTION
Add the following initialization option:
processing: true
Change your code for adding new rows to
$(".dataTables_processing").show();
setTimeout(function(){
_.each(file, function(row) {
t1.addRows(row)
});
t1.oTable.draw();
$(".dataTables_processing").hide();
}, 100);
DEMO
See this jsFiddle for code and demonstration.

Using Vuetify Data Tables, I'm trying to figure out if there's a way to determine what page the current selected item is on, then jump to that page. My use case for this is, I'm pulling data out of the route to determine which item was selected in a Data Table so when a user follows that URL or refreshes the page that same item is automatically selected for them. This is working just fine, however, I can't figure out how to get the Data Table to display the correct page of the selection.
For example, user visits mysite.com/11
The Data Table shows 10 items per page.
When the user enters the site, item #11 is currently auto-selected, but it is on the 2nd page of items. How can I get this to show items 11-20 on page load?
I ended up using a solution similar to what #ExcessJudgement posted. Thank you for putting that code pen together, BTW! I created this function:
jumpToSelection: function(){
this.$nextTick(() => {
let selected = this.selected[0];
let page = Math.ceil((this.products.indexOf(selected) + 1) / this.pagination.rowsPerPage);
this.pagination.sortBy = "id";
this.$nextTick(() => {
this.pagination.page = page;
});
});
}
I'm not sure why I needed to put this into a $nextTick(), but it would not work otherwise. If anybody has any insight into this, it would be useful to know why this is the case.
The second $nextTick() was needed because updating the sortBy, then the page was causing the page to not update, and since I'm finding the page based on the ID, I need to make sure it's sorted properly before jumping pages. A bit convoluted, but it's working.
I have problem in rendering a template
When a new data has been added, it won't go to the process of v-if even if the condition is both TRUE.
Can some please explain why?
I have provided some screenshot below to explain further my issue
This first image was my template for displaying the products, you will notice the add, update and remove in here.
The second image shows that I'm trying to add a new product
The third image shows that I have successfully added the new product. The problem is, the action button "update" is triggered but won't take any effect.
The image above shows that the update button works with the past data, but not with the new one.
This last image will prove that the button has been triggered. I've added a console.log to display the following upon clicking the update button.
INDEX of the row, which is [0].
The typeOf the variable 'isUpdate' [boolean].
The value of 'isUpdate' [True, False]
and the productID which is [151]
Any idea why it hasn't been triggered, or any idea how to debugged this?
If you want to see the code. I can provide it, just tell me which part are you looking for. As I don't have any idea which part has the error.
Thank you in advance.
Updated
AS per Amresh Venugopal Request
Here is the v-if in the template
<tr v-if='product.id > 0 && product.isUpdate' class='table-inputs'>
And the updatebtn function
canUpdate: function(data) {
console.log(data.pindex);
this.products[data.pindex].isUpdate = !this.products[data.pindex].isUpdate;
console.log(typeof this.products[data.pindex].isUpdate);
console.log(this.products[data.pindex].isUpdate);
console.log(this.products[data.pindex].id);
}
I only set the isUpdate value to 'true' if 'false', and viceversa.
The productID is added after the ajax save function.
I figure it out!
When I push the data in this.products, I didn't include the 'isUpdate' field.
Got it working now.
I wrapped my gridview with Pjax widget like this
\yii\widgets\Pjax::begin();
gridview
\yii\widgets\Pjax::end();
in order to make the gridview make ajax request when I click on each pagination.
I also use ['class' => 'yii\grid\CheckboxColumn'], in column as well.
and I find that when I'm on first pagination I checked some rows and then go to second page and check some rows but when I go back to first page what I've checked is gone.
My question is how can I keep all checkedrow for all pagination
With current conditions (Pjax, multiple pages, yii\grid\CheckboxColumn) it's impossible because of the way it works.
When you click on the pagination links all GridView html content is replaced by new one that comes from the AJAX response.
So obviously all selected checkboxes on the previous page are gone.
Few possible ways to solve that:
1) Write custom javascript and server side logic.
As one of the options, you can send AJAX request to server with parameter meaning that user has chosen to select all data for the bulk delete operation (or use separate controller action for bulk deletion). In this case actually we don't need to get the selected data from user, because we can simply get them from database (credits - Seng).
2) Increase number of displayed rows per page.
3) Use infinite scroll extension, for example this.
4) Break desired action in several iterations:
select needed rows on first page, do action (for example, delete).
repeat this again for other pages.
You can get selected rows like that:
$('#your-grid-view').yiiGridView('getSelectedRows');
[infinite scroll] : http://kop.github.io/yii2-scroll-pager/ will work good if you do not have any pjax filters. If you have filters also in play, do not use this plugin as it does not support pjax filters with it. For rest of the applications it is perfect to use.
Update1 : it seems to be straight forward than expected, here is the how I accomplished it
Add following lines to the checkbox column
'checkboxOptions' => function($data){
return ['id' => $data->id, 'onClick' => 'selectedRow(this)'];
}
Now add following JS to the common js file you will have in your project of the page where this datagrid resides
var selectedItems=[]; //global variable
/**
* Store the value of the selected row or delete it if it is unselected
*
* #param {checkbox} ele
*/
function selectedRow(ele){
if($(ele).is(':checked')) {
//push the element
if(!selectedItems.includes($(ele).attr('id'))) {
selectedItems.push($(ele).attr('id'));
}
} else {
//pop the element
if(selectedItems.includes($(ele).attr('id'))) {
selectedItems.pop($(ele).attr('id'));
}
}
}
Above function will store the selected row ids in the global variable array
Now add following lines to pjax:end event handler
$(document).on('pjax:end', function () {
//Select the already selected items on the grid view
if(!empty(selectedItems)){
$.each(selectedItems, function (index,value) {
$("#"+value).attr('checked',true);
});
}
});
Hope it helps.
I just solved this problem and it works properly with Pjax.
You may use my CheckboxColumn. I hope this can help. The checked items are recorded with cookies.
You can read the part with //add by hezll to understand how to fix it, because I didn't provide a complete general one.
Hope it works for you.

We wanted to use the portfolioitemstreegrid(https://github.com/RallySoftware/app-catalog/tree/master/src/apps/portfolioitemstreegrid) app since there was an issue with the old PortfolioDrilldownApp. we were able to add the edit app setting options by adding:
getSettingsFields: function () {
var fields = this.callParent(arguments);
fields.push({
type: 'query'
});
return fields;
},
but that doesn't filter anything it just shows the box.
What do we need to add to get the query box to work. The app has a filter already but it isn't flexible enough for us to run the queries we need.
I hoped too that doing something like this will allow wiring up of query into the treegrid filter, but it does not work. There is no storeConfig on a treegrid:
if (this.getSetting('query')) {
config.storeConfig.filters = [Rally.data.QueryFilter.fromQueryString(this.getSetting('query'))];
}
In a month or so a new hierarchical tree grid app will become available, and it will take a query from the app settings dialog. I would not suggest extending this portfolioitemstreegrid, also because it is using the head (unstable) version 'x' of AppSDK2.
I just want to show different messages.
Ext.Viewport.setMasked({
xtype: 'loadmask',
message: 'Downloading data. Please wait...'
});
When I download data from server I gave call to different functions.
Depending on function I want to change the message.
Please provide guide line or working code.
I have used
Ext.Viewport.unmask();
in every function and reset the message in that function.. but showing same message.
Very simple. Just get the Viewport loading mask, and update the message. Here is an example, once you set the loading mask and now want to change the text (or even other properties):
Ext.Viewport.getMasked().setMessage('This is a new message.');
var loadMask = Ext.getCmp('your view id which you want to use');
loadMask.setMessage(Get the message Dynamically or static);
