i hav开发者_如何学编程e a list of images which i am getting through ajax and then using jquery $.each() i loop through the images and display a image one after the other after an interval of one second. I want the user to be able click on a stop button and so that the user can stop at a particular image if he wants to. So i need to dynamically exit $.each() when the user clicks on the stop button. Is it possible to do it?
You can use return false
to break out of each()
loops early.
Example:
<script>
$("button").click(function () {
$("div").each(function (index, domEle) {
// domEle == this
$(domEle).css("backgroundColor", "yellow");
if ($(this).is("#stop")) {
$("span").text("Stopped at div index #" + index);
return false;
}
});
});
</script>

To break out of an each()
loop you would:
return false;
So your button could set a variable when clicked that the each loop checks each pass, then returns false when the variable is set.

We can stop the loop from within the callback function by returning false.
return(false);
should do it.
Use return false;
between each loop.
