Can I simulate a click on a hyperlink with jQuery code?
I have seen a couple of Stack Overflow posts which apparently relate to my question but none of them seem to do what I want.
I have a nested structure to display hierarchies (business units and brands) in a report:
<tr class="BrandRow1">
<td>
</td>
</tr>
<tr class='BrandRow1 StoreRow1'>
...
</tr>
<tr class='BrandRow1 StoreRow2'>
...
</tr>
and within this layout I use A
tags to show/hide the 'child' content (by making use of the class
attributes.
On load, I want to show all the 'nodes' if $('.StoreRow2').length
is less than say 4.
I use a function to do the toggling:
// Allow an item to toggle other items' visibility
$(".VisibilityToggle").click(function () {
var ControlledClass = findClass($(this), "Toggles-");
if (ControlledClass != "") {
$("." + ControlledClass).toggle();
var Text = $(this).attr("rel");
if (Text != "") $(this).attr("rel", $(this).attr("rev")).attr("rev", Text).text(Text);
}
return false;
});
and what I'd like to do is trigger the 'toggling' open by calling this from JS code.
I thought something like '$(".VisibilityToggle").click()` would do what I want but this doesn't seem to work in my code, but does if I call it manually via the JS console in Chrome. I suspect its to do with my code running before the events have been bound to the page.
Can you please assist?

you could use trigger:
$(".ABrand").trigger('click');
Is that what you wanted to achieve?
There's nothing wrong with the syntax you have: click() will trigger a click on the element.
$('.ABrand').click();
More markup is required to properly answer your question I would think, but take a look at live()
and delegate()
, which can be used outside document.ready
if you're worried that things aren't getting hooked up in time.
$(".VisibilityToggle").live("click", function() { ... } );
$("#Container").delegate(".VisibilityToggle", click", function() { ... } );
If you're having trouble timing the event bind (i.e. the .click(function(){})
) and the event trigger (i.e. the .click()
), why not just chain the two together?
$('.ABrand').click(function() {
// do 3 flips, 5 somersaults and a pirouette
}).click();
This way, you're sure the click trigger gets called after the click bind.
