IE8 with jQuery width

Question

I am trying to set a width dynamically on a div. This is correctly working with Safari, Chrome and Firefox but not in IE8. This is using jQuery UI for the slider function. Here is my code so far:

var ourStoryPosts = $(".ourStory .grid_12mod").children();
var ourStoryLength = ourStoryPosts.length;
var ourStoryWidth = $(ourStoryPosts[2]).outerWidth(true);
var ourStoryWrapperWidth = ourStoryLength * ourStoryWidth;
var maxSlider = ourStoryWrapperWidth - 1020;

$(".ourStory .grid_12mod").width(ourStoryWrapperWidth);

$(".ourStorySlider").slider({ 
    step: 1, 
    max: maxSlider,
    slide: function( event, ui) {
        $(".ourStory").css({
            "left" : -ui.value
        });
    }
});

As you can see, I am using variables to set these values. The width() method is not working as expected.

I have tried using the String() constructor to explicitly cast to a string. I have tried using + "px" at the end of the expression as well. Each time, the div is being set to 0px . Why is this not working correctly?

您可以尝试设置CSS属性的宽度吗？

$(".ourStory .grid_12mod").css('width', ourStoryWrapperWidth.toString() + 'px');

Not sure what the actual issue was, but using native JS fixed it for me:

var elem = document.querySelector(".grid_12mod");
var ourStoryChildren = elem.children;

Using the jQuery 1.9 method of children() logged a result of 5 elements in Safari, Chrome and Firefox, while IE8 logged 1 . Using the native children attribute of the elem object fixed the problem and logged 5 for all browsers.

The reason this was logging 0 is because IE8 was returning only 1 child element, when 5 existed, therefore the math was off and IE8 was trying to find the second array element when it only found 1 element.
