我有一个像这样的对象;

I have an object like;

var defaults = {
        id: 'ActionSlider',
        element: '',
        closeBtnWidth: 55,
        panelWidth: 320,
        class: '',
        css: {},

当我在IE8标准中运行我的页面时，它给了我跟随错误;

SCRIPT1028：预期的标识符，字符串或数字

和积分到行：class：''，

and points to the line : class:' ',

任何人都可以告诉我为什么我不能用这个用于IE？
是保留字还是什么？

can anyone please tell me why i cant use this for IE? is it a reserved word or something?

推荐答案

你需要在周围添加引号class 这是一个保留字。另请注意，您应该删除最后一个逗号：

You need to add quotes round the class which is a reserved word. Please also note, that you should remove the last comma:

var defaults = {
        id: 'ActionSlider',
        element: '',
        closeBtnWidth: 55,
        panelWidth: 320,
        "class": '',
        css: {},
        create: function() {}
    }
