当您点击此页面上的“添加到行李”时，它每次都会冻结IE6。我怎么能弄清楚它冻结的原因？有人有更直接的答案吗？

调试从外部立即冻结的东西并不容易。但是清理整体，删除不重要的东西，检查功能然后再进行下一步总是一个好主意。

例如：

// preparethe form when the DOM is ready 
$(document).ready(function () {
    // bind form using ajaxForm 
    $('.add_to_cart_form').ajaxForm({
        beforeSubmit: loading,
        success: myBox
    });
});
// preparethe form when the DOM is ready
$(document).ready(function () {
    // bind form using ajaxForm
    $('.add_to_cart_form').ajaxForm({
        beforeSubmit: loading,
        success: myBox
    });
});

不难看出在那里有两次这个部分为您的应用程序添加更多精确度，而不是复制和粘贴。

为什么这个JavaScript会冻结IE6？
