jQuery Set or Change Input Hidden Field Value: Here in this tutorial will learn how we can set the value to the input hidden field.  With the jQuery library, we can manipulate HTML DOM  as well as event handling, and animate easily. In jQuery to set a hidden field value, we use.val() method. 

The jQuery .val() method is used to get or set the values of form elements such as input, select, textarea. You can also check our previous article on how to get the value of the hidden field in jQuery.

2 ways set Hidden Field Value in jQuery

  1. Set hidden field value by Id in jQuery
  2. Set hidden field value by name in jQuery

Add HTML Markup

Here 1st we add a textbox, where the user enters any value, and then we set this textbox value to our input hidden field.

<input id="txtName" value="" type="text"/>
<input id="myInputHidden" name="myInputName" type="hidden" value="Codepedia" />

Here we added one textbox and one hidden field.

#1 jQuery Code to set hidden field value by ID

var getTxtValue = $("#txtName").val(); // this gives textbox value   
$("#myInputHidden").val(getTxtValue); // this will set hidden field value
alert(getValue); 

Above jQuery code will take textbox value into the variable getTxtValue  and using .val() set its value to our hidden field.
