How to trigger in input button?

i have a input button in a form:

<input type="submit" value="" class="hidde" name="free"  id="helpdiv" onmouseover="this.style.background='url('../images/thank_you/thank.png');'" onmouseout="this.style.background='url('../images/thank_you/thank_you.png');'" style="width: 236px; height: 127px;">

and a jQuery script that has an event:

onlike:function(response){
    $('.uncontent').hide('fade');
    $('input#helpdiv').trigger('click');
}

when that function triggers i would like the input button to be triggered as well. the function is working because $('.uncontent').h开发者_如何学Cide('fade'); gets triggered

any ideas?

Edit:

$('input#helpdiv').trigger('click') or

$('input#helpdiv').click()

won't work for some reason

Try...

$('#helpdiv').click();

If you're trying to submit a form via this button select the <form> element and call submit() on it like so....

$('#helpdiv').parents('form').eq(0).submit();

Your trigger is fine. You have some funky quotes going on in your mouseover events. This is why we should avoid doing that.

id="helpdiv" onmouseover="this.style.background='url('../images/thank_you/thank.png');'" 

See the background='url('.. ?

Try this:

HTML:

<input type="submit" value="" class="hidde" name="free" id="helpdiv" style="width: 236px; height: 127px;" />

JQuery:

$('#helpdiv').hover(function(){
    $(this).css('background-image','url("../images/thank_you/thank.png")');
},function(){
    $(this).css('background-image','url("../images/thank_you/thank_you.png")');
});

// Test it
$('#helpdiv').click(function(){
    alert('helpdiv clicked');
});

Next step would be to abstract your CSS as well ;)
