Set textbox to readonly and background color to grey in jquery

Question

Good day,

I would like to make a text box in my jsp to become readonly and its background color to grey like disable in Jquery. The following is my code :

if(a)
  $('#billAccountNumber').attr('readonly', 'true');

I not prefer using attr('disable', 'true');, because the value will become null when I submit form. Any ideas instead of write second line of code to change the style?

Answer 1

there are 2 solutions:

visit this jsfiddle

in your css you can add this:
     .input-disabled{background-color:#EBEBE4;border:1px solid #ABADB3;padding:2px 1px;}

in your js do something like this:
     $('#test').attr('readonly', true);
     $('#test').addClass('input-disabled');

Hope this help.

Another way is using hidden input field as mentioned by some of the comments. However bear in mind that, in the backend code, you need to make sure you validate this newly hidden input at correct scenario. Hence I'm not recommend this way as it will create more bugs if its not handle properly.
