If conditions false then prevent default

I have a link. When some one clicks on that I want to check some conditions before letting it work. If it's false the default action should be prevented.

$(.pager-next a.active).click(function(event) {

    if (!a == 1) {

        event.preventDefault();

    }           

});

The link should only work if a is equal to 1. Is the above code correct. a is set to 1 if a particular condition is met. The link should only work if the condition is met.

Assuming by 'should only work if a is equal to 1' you mean the text of the a element is equal to 1, try this:

$(.pager-next a.active).click(function(event) {

    if ($(this).text() != 1) {

        event.preventDefault();

    }           

});

You can amend text() to use whichever attribute of the element is available to you in jQuery.

UPDATE

my a is a var which hold the value 0 until a condition is met.

In which case, the problem was simply that your equality operator was incorrect:

$(.pager-next a.active).click(function(event) {

    if (a != 1) {

        event.preventDefault();

    }            

});
