Getting Script on error on following Jquery function

Question

var clickable = ApplyClickableLinkToClass($j(".rc_blueBtn"));
setTimeout(clickable, 1000);

But if I call it like this there is no script error pop up :

ApplyClickableLinkToClass($j(".rc_blueBtn"));

The method is as follows :

ApplyClickableLinkToClass = function(selectedElements) {
 // Go through each of the passed in selections and try to apply a link to them
 $.each(selectedElements, function() {
 var linkElement = $("a:first:not(.do-not-apply-clickable-link)", $(this));
 var link = linkElement.attr("href");
 if (!IsNullEmptyOrUndefined(link)) {
 $(this).click(function(firstLink) {
 var divToLink = firstLink;
 return function() {
 $(divToLink).unbind('click');
 if (divToLink.attr("target") != "_blank") {
 window.location = link;
 return false;
 }
 };
 }(linkElement));
 }
 });
}

The error is just a js popup "An error has occured in the Script on this page"

• n8wrl: If you use FireBug (FireFox) or IE 9's F12 you can get better diagnostics.

Answer 1

Your clickable variable is set to the return value from calling the ApplyClickableLinkToClass function, which is undefined. So by passing clickable to setTimeout you're passing undefined.

Try this:

setTimeout(function() {
 ApplyClickableLinkToClass($j(".rc_blueBtn"))
}, 1000);
// OR
var clickable = function() {
 ApplyClickableLinkToClass($j(".rc_blueBtn"))
}
setTimeout(clicable, 1000);

• StevieB: also can you see what that function is supposed to do, because it doesnt open links in a new windowe because thats what I expected

Answer 2

setTimeout() expects the first argument to be a function, or the source code you want to execute, as a string (this version is generally deprecated). But you're passing in the result of your ApplyClickableLinkToClass() function, not the function itself.

You want something like:

var clickable = function() {
 ApplyClickableLinkToClass($j(".rc_blueBtn"));
};
setTimeout(clickable, 1000);

• StevieB: And does this still actually run the ApplyClickableLinkToClass function ?
