JQuery escapeSelector() Method

Last Updated : 25 Jul, 2024

The escapeSelector() method in jQuery is used to escape CSS selectors which have special significant character or string. It can select the element of id(‘#ID1’, ‘#ID2’) and elements of class(‘.class1’, ‘.class2’). Let us understand it with the help of few examples.

Syntax:

jQuery.escapeSelector( selector )

Parameters: This method accepts single parameter selector that holds a string which contains a selector expression to escape (example ‘#ID1’ etc).

Example 1:

This example selects elements of class = ‘.list’.

        var elUp = document.getElementById("GFG_UP");
        var elDown = document.getElementById("GFG_DOWN");

        elUp.innerHTML = 
            "JQuery | escapeSelector() method";

        function Geeks() {
            $("ul").find("." + $.escapeSelector(
                        ".list")).addClass("highlight");

            elDown.innerHTML = "The list elements of class"
                    + " '.list' are highlighted not the "
                    + "elements of class 'list'";
        } 
    </script>
</body>
