Javascript IE 错误:对方法或属性访问的意外调用 [英] Javascript IE error: unexpected call to method or property access

问题描述

我有以下代码，它在除 IE 之外的所有内容中都正常工作(像往常一样).它给了我对 Jquery 中方法或属性访问的意外调用，我不知道如何调试它.我一直在使用 IE 开发人员工具栏，这对这个错误没有用，只是给了我 12 号行(在 jquery 脚本中).

I have the following code and it's working (as usual) in everything but IE. It's giving me an unexpected call to method or property access in Jquery and I have no idea how to debug it. I've been using the IE developer toolbar, which is useless for this error and just gives me a line no 12 (inside the jquery script).

非常感谢任何帮助:

<script type="text/javascript">
$(document).ready(function () {

    $.history.init(pageload);

    $('a[href=' + window.location.hash + ']').addClass('selected');

    $('a[rel=ajax]').click(function () {

        var hash = this.href;
        hash = hash.replace(/^.*#/, '');
        $.history.load(hash);

        $('a[rel=ajax]').removeClass('selected');
        $(this).addClass('selected');
        $('.loading').show();

        getPage();

        return false;
    });
});

function pageload(hash) {
    if (hash) getPage();
}

function getPage() {

    hash = document.location.hash;
    hash = hash.replace(/^.*#/, '');
    var data = 'page=' + encodeURIComponent(hash);
    $.ajax({
        url: "index.php",
        type: "POST",
        data: data,
        cache: false,
        success: function (html) {
            $('.loading').hide();
            $('tbody').html(html);

        }
    });
}
</script>

这是历史插件:http://plugins.jquery.com/project/history

这是我一直在关注的演示:http://plugins.jquery.com/project/history

And here is the demo I have been following: http://plugins.jquery.com/project/history

仍然将 window.location 改回 document.location 似乎没有什么区别

Still changing window.location back to document.location doesn't seem to make a difference

我迷失了这一点.当我更改标签时，我调用它确实可以发布，因此它可以正常工作，但是在 IE 中，设计已全部损坏，并且我单击的下一个链接不发布.真的很奇怪！！在 Firefox、Opera 等中都可以正常工作

I'm lost on this one. When I change the tag I'm calling to it does post so it's working, but in IE the design is all broken and the next links I click on don't post. Really strange!! Works fine in firefox, opera, etc.

推荐答案

我有点惊讶 IE 会抱怨它，但它确实是一件好事:您在 getPage 用于 hash(例如，将 var 放在第一次使用的前面).

I'm a bit surprised IE complains about it, but it's a good thing it does: You're missing a declaration in getPage for hash (e.g., put var in front of the first use).

在其他情况下，它大概创建了一个隐式全局(window 对象的一个​​属性，称为 hash)，这当然是一个 坏事(tm)，但据我所知，它根据规范是正确的(相关部分为 8.7 [参考类型"] 和 10.1.4 ["作用域链和标识符解析"]).

On the others it's presumably creating an implicit global (a property of the window object called hash), which is of course a Bad Thing(tm), but as I understand it it's correct according to the specification (the relevant sections being 8.7 ["The Reference Type"] and 10.1.4 ["Scope Chain and Identifier Resolution"]).

尽管如此，IE 仍在抱怨它，但仍然感到惊讶.它必须与 jQuery 调用点击处理程序的范围有关.

Still surprised IE is complaining about it, though. It must have to do with the scope in which jQuery is calling your click handler.
