Question

我的一项职能是,当用户选择一个或多个项目时,将这些项目移至清单箱顶(选定的提炼)和滚动到顶,以便其重新可见。它在我测试的所有主要浏览器工作。当我拥有这一职能时,问题就出现在一个桌子内。当我这样做并使用国际电子数据8时,它就进行分类和复制;适当强调,但只是向顶点倾斜。 Java本通过基本的JALint检查,网页通过超文本验证。我是否找到了IE8的qui子? 我把这个名单箱式和样子放在一起;滚动功能错失了吗?

<script type="text/javascript">
function Arrange(obj) {
    var countSel = 0, countNSel = 0, i, arr_selected = [], arr_unselected = [];
    for (i = 0; i <= obj.length - 1; i++) {
        if (obj.options[i].selected) {
            //create array with all selected items then sort it
            arr_selected[countSel] = [];
            arr_selected[countSel][0] = obj.options[i].text;
            arr_selected[countSel][1] = obj.options[i].value;
            countSel = countSel + 1;
            arr_selected.sort();
        }
        else {
            //create array with all UNselected items then sort it
            arr_unselected[countNSel] = [];
            arr_unselected[countNSel][0] = obj.options[i].text;
            arr_unselected[countNSel][1] = obj.options[i].value;
            countNSel = countNSel + 1;
            arr_unselected.sort();
        }
    }
    if (countSel !== 0) {
        //overwrite listbox options with selected items
        for (i = 0; i <= countSel - 1; i++) {
            obj.options[i] = new Option(arr_selected[i][0], arr_selected[i][1]);
        }
        //overwrite listbox options with UNselected items
        for (i = 0; i <= countNSel - 1; i++) {
            obj.options[countSel] = new Option(arr_unselected[i][0], arr_unselected[i][1]);
            countSel = countSel + 1;
        }
    }

    //for showing selected items
    //scroll to the top of the list and select the appropriate items
    //it s in reverse order because IE8 wanted to only scroll to the last item selected
    obj.selectedIndex = 0;
    for (i = arr_selected.length - 1; i >= 0; i--) {
        obj.options[i].selected = true;
    }
}

这很可能是国际能源论坛8中的一个rk子,但你的法典实际上并没有说什么是roll,因此,我要指责国际能源8。 http://jsfiddle.net/Df7dQ/“rel=“nofollow noreferer” 解决你的问题:
