在FF和Chrome中接收用于JavaScript函数的TypeError
Receiving a TypeError in FF and Chrome for JavaScript Function
请帮忙。。。我已经尽了一切努力来纠正Firefox和Chrome中的这个错误。运行函数时收到当前错误。"TypeError:obj1.options不是函数"。我尝试了很多事情，甚至尝试将onclick函数更改为JQuery.click（）函数，以及在JQueryDocument.ready函数之间放置。它在IE中工作得很好，但在其他浏览器中会抛出TypeError。事实上，我得到了多个类型错误，一个用于AddMember函数，另一个用于Remove Member。这可能是过时的JavaScript。如有任何帮助，我们将不胜感激。感谢
function RemoveMember(idx, idx2){
//centralizes code to remove selected items from a MULTIPLE SELECT (listbox).
//loops "backward" to maintain valid indexing counters while removing items.
var obj = idx;
var obj2 = idx2;
var nCount = 0;
nCount = obj.options.length - 1;
for ( nCount; nCount > -1; nCount -- ) {
if ( obj.options(nCount).selected == true ) {
var oOption = document.createElement("OPTION");
oOption.text = obj.options(nCount).text;
oOption.value = obj.options(nCount).value;
obj.options.remove(nCount);
//JJK added add back to avail list
obj2.add(oOption);
}
} //for
//sort both listboxes
sortOptions(obj2);
sortOptions(obj);
}
这是完整的html文件，所以你可以看到它的全部。我们本质上有两个列表框，并且有两个带有点击操作的图像，用于将列表项从左侧第一个列表集添加或删除到第二个列表集。

</html>obj.options(nCount)
应该是
obj.options[nCount]
obj是HTMLSelectElement对象。HTMLSelectElement没有options方法，因此以下内容不正确：
obj.options(nCount) // XXX
HTMLOptionsCollection对象确实具有options属性，记录如下：
返回包含此元素所包含的
<option>元素集的HTMLOptionsCollection。
HTMLOptionsCollection有两种方法：
item(index)-返回给定的基于零的索引处的特定节点（如果超出范围，则为null）namedItem(name)-返回具有给定DOMString（即字符串）id的特定节点。如果不存在此类命名节点，则返回null
这意味着你应该使用
obj.options.item(nCount)
HTMLOptionsCollection的父类显示
在JavaScript中，访问
HTMLCollection对象的代码，为了获得给定HTMLCollection的项，可以使用方括号语法，而不是直接调用item()或namedItem()方法。方括号中的数值与item()的工作方式相同，字符串值与namedItem()的工作方式一样。
这意味着你也可以使用
obj.options[nCount]
