Using jQuery to set elements is not available

We can use jQuery to change HTML elements non-CSS properties. For example, you can disable buttons.

When you set the button to disabled, the button will turn gray and cannot be clicked.

jQuery has a .prop() method that allows you to adjust the properties of elements.

The following code shows how to disable all buttons:

$("button").prop("disabled", true);

Example: Let the target1 button be disabled

<script>
$(document).ready(function() {
$("#target1").css("color", "red");
$("#target1").prop("disabled", true);
});
</script>
<!-- Only change code above this line. -->
<div class="container-fluid">
<h3 id="jQuery-nbsp-Playground">jQuery Playground</h3>
<div class="row">
<div class="col-xs-6">
<h4 id="left-well">#left-well</h4>
<div class="well" id="left-well">
<button class="btn btn-default target" id="target1">#target1</button>
<button class="btn btn-default target" id="target2">#target2</button>
<button class="btn btn-default target" id="target3">#target3</button>
</div>
</div>
<div class="col-xs-6">
<h4 id="right-well">#right-well</h4>
