Below is the basic example of how to use AJAX in WordPress. It show you how to using javascript pass the variable to PHP function and then return back to javascript.

Javascript

var ajaxurl = '<?php echo admin_url() ?>admin-ajax.php';
jQuery(document).ready(function () {
	jQuery.ajax({
		url: ajaxurl,
		data: {
			//This action must same with the PHP function name
			"action": "ajax_request",
			"params": "wordpress ajax"
		},
		success:function(data) {
			//This is the result return from PHP function
			console.log(data);
		},
		error: function(errorThrown){
			//This is the error return
			console.log(errorThrown);
		}
	});
});

Below is the function I use to only number, delete, backspace and tap are allow.

$(document).on("keydown", "#number", function(e) {
	var key = e.charCode || e.keyCode || 0;
	
	if (key == 8 || key == 9 || key == 13 || key == 46 || key == 110 || key == 190 || (key >= 35 && key <= 40) ||(key >= 48 && key <= 57) || (key >= 96 && key <= 105)) {
		return;
	} else {
		return false;
	}
});

If using fancybox ajax display the Yii2 cactiveform you will found that the client validation are not working.

Its due to the form ID was invalid or duplicated in same page. what you need to do is assign a new form id inside cactiveform.

Example

$form = ActiveForm::begin([
  'enableClientValidation' => true,
  'id' => 'new_form_id'
]);

In Yii2 now you are allow pass an array as param to gridview column for display the data. Below is the example how to pass array to gridview column.

Exmaple:
The $status is an array and $data is the model results.

'content' => function($data) use ($status) {
  return (isset($status[$data->status]) ? $status[$data->status] : $data->status);
},

Complete Example:

 $model->search(),
  'filterModel' => $model,
  'showOnEmpty'=>true,
  'columns' => [
    'id',
    'name',
    [
      'attribute' => 'status',
      'filter' => $status,
      'content' => function($data) use ($status) {
        return (isset($status[$data->status]) ? $status[$data->status] : $data->status);
      },
    ],
  ],
]); ?>

To set the opacity level for a <div> element as the below example:

div {
    opacity: 0.5;
}

But the following example will let the content inside the <div> become transparent as well.

Instead of using “opacity” to set transparent background-color. You can try using “rgba” function as below.

background-color: rgba(255, 0, 0, 0.5);

Now, only the background is transparent.
