How can use :contains() Selector to determine the object has a certain keyword when it is clicked?

How can use :contains to find the object has a certain keyword when it is clicked?

<a href="#" class="click">&#187; Read More</a>

$('.click').click(function() {

   开发者_Go百科if($(":contains('More')", this)) alert('1');

});

I get the alert whenever it contains the keyword or not... how can I make it?

You need to use is to see if an element matches your :contains selector:

$(".click").click(function () {
    if ($(this).is(":contains('More')")) {
        alert('1');
    }
});

Example: http://jsfiddle.net/3N8ek/

Try this:

$(".click:contains('More')").click(function() {

   alert('1');

});

You are always getting alert because you are not checking for length property of jQuery object. jQuery always returns at least an empty object when it do not find any match. So if($(":contains('More')", this)) will always return true no matter what.

$('.click').click(function() {

   if ($(this).is(":contains('More')")) {
     alert('1');
   }

});

This should work:

if($(this + ':contains("More")')) alert('1');

See :contains-docs for more on the usage.
