Question

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.

Answer 1

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();
    }            
});
