For some reason no matter what, the pageNumber ends up being the last value in the loop for the loopCounter. Now I would understand that if I were directly using loopCounter in the closure itself, but I'm not. As you can see from the code below, I am creating a new variable within the closure to take the current value of loopCounter.
Only thing I can figure is (Assuming that javascript treats everything as a reference type) that pageNumber is taking the reference to loopCounter so no matter how many times I create a new pageNumber, it's always pointing at the loopCounter object. Therefore, whatever value loopCounter ends up with will be the value any pageNumber will point to.
How do I get it to not point at loopCounter but create a new pageNumber per iteration that holds the current loopCounter value?
for (var loopCounter = result.StartingPoint; loopCounter <= result.HighestPageCount; loopCounter++)
{
...
var newDiv = document.createElement('div');
...
//trying to remove the reference to loopCounter
var pageNumber = loopCounter;
newDiv.onclick =
function(event)
{ //Right here ---V
getResultUsingUrl(result.PagerPreLink + "&pageNumber=" + pageNumber);
};
...
}
SOLUTION
Thanks to a couple answers below:
function createClickMethod(loopCounter, link)
{
var pageNumber = loopCounter;
return function(event) { getResultUsingUrl(link + "&pageNumber=" + pageNumber); };
}
and I can call like:
newDiv.onclick = createClickMethod(loopCounter, result.PagerPreLink);
Or if I want to use jQuery... suggested below:
jQuery(newDiv).click
(
createClickMethod(loopCounter, result.PagerPreLink)
);
