How to resume click event in jQuery

I have used unbind to detach the the click event for certain condition. After that I want to resume that click event. How to do this?

jQuery('#div1 span').click(function(){
    if(jQuery('#div1 a:last').hasClass('current'))
    {
    jQuery('#div1 span').unbind(click);
    }

}
    jQuery('#div1 a').click(function(){

         jQuery(this).addClass('current');
//here i want to resume click event for #div1 span is this possible
    });

<div id ="div1"><span>&开发者_Python百科lt;/span><a></a><a></a><a></a></div>

Here when the current class is not with last anchor I want to trigger click on span.

You can explicitly .bind()^help and .unbind()^help a method:

function my_click_handler(event) {
    // click handler code
}

// bind that handler to #element
$('#element').bind('click', my_click_handler);

// remove the handler
$('#element').unbind('click', my_click_handler);

// bind again
$('#element').bind('click', my_click_handler);

It might be easier if you just checked for a variable like clickHandlerEnabled in your onclick event handler instead of unbinding and re-binding the event handler.

If it's element-specific you could store it in its `data()``:

$('.elem').click(function(e) {
    if($(this).data('clickDisabled')) {
        return;
    }
});

And to set it:

$('#someElem').data('clickDisabled', true /* or false to re-enable clicks */);

if you call Jquery click event again under other condition to resume it, jquery will automatically bind it again.
