If element contains certain text

Question

$(\'.test\').css(\'background\',\'red\');

Some text

How can I .addClass(\'test\') if #exa

Answer 1

You can use $("#example") to get a jQuery wrapper for the element, then use text() to get its text, and use String#indexOf, e.g.:

var ex = $("#example");
if (ex.text().indexOf("text") !== -1) {
    ex.addClass("test");
}

You can also use :contains("text") in the selector as F. Calderan shows, although note that when you use non-standard pseudo-selectors like that, jQuery can't use the underlying browser's built-in stuff for finding elements, so it can be slower. The above will allow jQuery to use document.getElementById. There are only a few situations where the speed really matters, though.
