bad87fee1348bd9aed808826	Disable an Element Using jQuery	6	17563

Description

You can also change the non-CSS properties of HTML elements with jQuery. For example, you can disable buttons. When you disable a button, it will become grayed-out and can no longer be clicked. jQuery has a function called .prop() that allows you to adjust the properties of elements. Here's how you would disable all buttons: $("button").prop("disabled", true); Disable only the target1 button.

Instructions

Tests

tests:
  - text: Disable your <code>target1</code> button.
    testString: assert($("#target1") && $("#target1").prop("disabled") && code.match(/["']disabled["'],( true|true)/g));
  - text: Do not disable any other buttons.
    testString: assert($("#target2") && !$("#target2").prop("disabled"));
  - text: Only use jQuery to add these classes to the element.
    testString: assert(!code.match(/disabled[^<]*>/g));
