**How to get hidden field value in jQuery?**
To get the value of a hidden field in jQuery, you can simply use the .val() method. The .val() method is used to get the value of input, select, and textarea elements. You just need to select the hidden field using its id, class, or any other selector, and then call the .val() method on it to retrieve the value.
For example, if you have a hidden field with id “myHiddenField”, you can get its value like this:
“`javascript
var hiddenValue = $(‘#myHiddenField’).val();
“`
This will store the value of the hidden field in the variable hiddenValue.
