Getting the underlying DOM element from a jQuery selector can be a convoluted task. Consider the following scenario:
<input type="checkbox" id="bob" /> var checkbox = $("#bob").click(function() { //some code });
To determine the checked value of the checkbox later, a direct method for accessing the DOM element is required. The is(":checked") method only serves as a workaround.
Solution:
jQuery provides an easy method to access the raw DOM element:
$("table").get(0); // or simply $("table")[0];
However, such access is generally not necessary. For instance, the checkbox example can be rewritten more concisely using jQuery methods:
$(":checkbox").click(function() { if ($(this).is(":checked")) { // do stuff } });
Additionally, jQuery methods offer enhanced functionality and support cross-browser compatibility, making them preferable to raw DOM element access.
