Question

I am using jquery-1.7.2.min.js

I’m getting TypeError:

$("#TextBox1").removeattr is not a function [Break On This Error]   
$("#TextBox1").removeattr("disabled"); 

Why?

Answer 1

The correct function name is removeAttr(), not removeattr:

$("#TextBox1").removeAttr("disabled");

But starting from jQuery 1.6 it’s better to use the .prop() method for setting native attributes such as disabled and checked:

$('#TextBox1').prop('disabled', false);
