Make custom field read only on Jira Edit Screen using javascript

sbhutada

I am trying to make a custom text field read-only on the edit screen of jira using javascript, but looks like below code is not working.

jQuery(document).ready(function($) {

    JIRA.bind(JIRA.Events.NEW_CONTENT_ADDED, function(e,context) {

var projectName = AJS.$("#project-name-val").text();
console.log("RFC projectName "+projectName);

if (projectName == "RT")
        {
callReadonlyFunction();
        }
 }
});

function callReadonlyFunction(){
$('#edit-issue').click(function() {
           console.log("Edit Button Clicked Start");
           AJS.$("#customfield_13911").attr("readonly", true); //text field
           console.log("Edit Button Clicked End");
      });
}

 In the console log, I do see messages but for some reason, the field is not set to read-only.

Why are you trying to do it with JS if you have Scriptrunner?

Go to "add-on" page and in the left panel you have "behaviours".

There you can determine a field with 3 options:

Required (Optional) 
Writable (Readonly) 
Shown (Hide)

So choose the "Writable (Readonly)" for your field.
