Yii - reload dynamically added CGridView - yii

if append to page the CGridView ('myGridViewID') by ajax, I can't reload it.
$.fn.yiiGridView.update('myGridViewID');
TypeError: settings is undefined
$grid.addClass(settings.loadingClass);

Use renderPartial in controller action:
$cs = Yii::app()->clientScript;
$cs->reset();
$cs->scriptMap = array(
'jquery.js' => false, // prevent produce jquery.js in additional javascript data
);
// Look at 4th parameter: with TRUE value, your view will have additional javascript data.
$this->renderPartial('_partialViewWithGrid', array(), false, true);

Here is a wiki for dynamic CgridViews in the same view. That should work.

The problem with dynamically loaded CGridViews (and everything containing ajax) is that CController::renderPartial() does not render the required javascript code for them to work properly, unlike CController::render(), which includes the required layout and JS.
There is an extension called ZController which offers a workaround for this problem, but due to the way CGridviews are reloaded (by making an ajax call to the same URL)... when you try to filter/sort/page a CGridView loaded via AJAX, the subsequent Ajax call will replace the whole contents of your browser window, but I honestly think that maybe (only maybe) this workaround could help, but I haven't had the time to try it out.
That is why I currently avoid loading CGridViews using AJAX.

JavaScript not executing after paginating through products in BigCommerce Cornerstone theme

I have a small bit of JavaScript which is not firing after navigating through paged results in a BigCommerce Cornerstone theme (using Cornerstone 6.7.0).
I've added the following to the onReady() method in the category.js file:
$('.mm-button').on('click', (e) => alert("clicked"));
This will execute on an initial page load but not after clicking on pagination links (next, prev, page number).
I've also tried moving the JavaScript into its own .js file and including it into the theme. The same behavior happens where it executes on the initial page load but not after paging through records.
The issue here is that pagination actually works by editing the content via JavaScript, so it does not run the category onReady() again. You could add the JavaScript into the page content function, but a simpler method is to simply delegate the click event. Change your code like this:
$('body').on('click', '.mm-button' (e) => alert("clicked"));

CListView with ajax

I am new to Yii, I am trying to get a CListView to update using ajax instead of refreshing the page. To make the simplest example, I am just feeding the CListView with a dataprovider and giving it the itemView parameter, nothing else. I want the pagination to update the page without refreshing. It works with gii generated crud pages but will not work with mine. I have added nothing extra, the code for the gii generated example and my own should be the same. Is there some setup step I am missing? Is there javascript missing in my layout that the default layout has perhaps? Thank you in advance.
It turns out that I was loading jQuery in my layout which was interfering with the jQuery library automatically loaded in Yii. Simply removing my jQuery include solved the problem. I will chalk this one up to being new at Yii and not knowing the inner workings of how it automatically includes javascript. Thanks guys, Rajat you put my mind on the right track, thanks.

how can I use the fileupload helper when it is loaded in another page using the load jquery method?

I have the following problem, one page load in one of his div using the Load method from Jquery Ajax another page that use the FileUpload Asp.net Helper. Alone that page Works fine, but inside this div the upload button apparently calls the hosting page, not the page that original has the helper.
In consecuence, How can correctly use the helper loaded from another page?
In a scheme I think that this is happening:
And I want this to happen, but don't know how to do it:
The upload button submits the form. It will be submitted to whatever location is specified in the action attribute of the form. Therefore you should set the action attribute value to the page that you want the form to post to.
This will be easier to manage if you set includeFormTag to false. It is true by default:
#FileUpload.GetHtml(
initialNumberOfFiles: 1,
allowMoreFilesToBeAdded: false,
includeFormTag: false,
uploadText: "Upload",
name: "Upload1"
)
You will then need to provide your own form tag. Make sure you include the correct enctype for managing file uploads:
<form action="somePage" method="post" enctype="multipart/form-data">
...

:remote => true/data-remote on a form loaded via ajax

In my Rails app, I have a form that is loaded via Ajax using jQuery load method.
function load_sales_form(product_id) {
$("#sales_form").load("<%= url_for(:action => :show_sales_form) %>"/ + product_id);
}
The loaded form has a form_for tag with the :remote => true option and it does add the data-remote="true" attribute to the form.
But the form isn't submitted using Ajax when the user clicks the submit tag button. It works fine if the form is loaded in the standard, non-ajax way, but it the form is loaded via ajax after the document is ready, is does not submit using ajax, it submits as a standard form.
From what I studied so far, this happens because the rails.js file (which contains the stuff that allow data-remote forms to be submitted via ajax) does not apply it's features to html content loaded via ajax.
Is it possible to force rails.js file to apply it's features to content loaded via Ajax?
Same situation here. I found a solution.
Not the dynamic loading, but incorrect triggering of submit event was the cause in my case.
I had a Bootstrap modal with data-target and href attributes set. This causes the content inside a .modal-body to be loaded via AJAX from address specified in href.
The modal was pre-equipped with save button (outside of the loaded form), which called the submit like this.
$modal.find("form.loaded_form").get(0).submit(); // INCORRECT
The former only executes raw submit, but:
$modal.find("form.loaded_form").trigger('submit'); // CORRECT
does the trick.

Setting returnURL for CButtonColumn button

I'm looking at the controller for the default Delete button in the CButtonColumn class. It manages to return to the previous web-page after deleting a CGridView line and remain on the same page of the CGridView, as opposed to going to the first page. The lines responsible for this in the associated controller seem to be:
if (!isset($_GET['ajax']))
$this->redirect(isset($_POST['returnUrl']) ? $_POST['returnUrl'] : array('admin'));
I would like to create a new custom button that has this behavior (i.e. returning to the previous view without resetting the pagination to page 1), but simply including the above lines of code in the button's associated action does not do the trick. I think I need to send that 'returnUrl' parameter somehow, but I cannot figure out how :)
The 'returnUrl' code you are looking at uses a POST variable for the returnUrl. To use this, you will need to POST that somehow. On the View this code is called from I am assuming there is a <input name="returnUrl"> field in the form. You should make sure this field (populated with the correct URL value) is on all of the Views you are POSTing from in order to access that POST variable in your Controller action.
If you are POSTing to the deleteAction via AJAX, I think you can set the $_POST['returnUrl'] variable with the jQuery AJAX function.
Another way to go might be to use CWebUser's returnUrl SESSION variable instead of this POST variable. I have never done this, but it's built in to Yii so I assume it works OK.
I never really liked the hacky $_POST['returnUrl'] that Gii generates anyway.
ANOTHER thing you could do, possibly, is look at the $_SERVER['HTTP_REFERER'] variable, and use that for the return redirect in your deleteAction. I don't know if that will be set correctly though, with complications from the 302 redirect/rewrites that Yii does.
Good luck!
You can set the return url via the CHtml::link call. Here is an example using delete
CHtml::link(
'Delete',
'#',
array('submit'=>array('delete','id'=>$model->id),
'params'=>('returnUrl'=>'controller/action...'),
'confirm' => 'Are you sure?'
)
);
