Javascript“window.open"代码在 Internet Explorer 7 或 8 中不起作用 [英] Javascript "window.open" code won't work in Internet Explorer 7 or 8

问题描述

我在我的网站上使用这段 jQuery/Javascript 代码来打开一个弹出窗口:

I am using this chunk of jQuery/Javascript code on my site to open a popup window:

$('#change_photo_link').click(function(){
    $id = $('#id').attr('value');

    window.open("photo.upload.php?id=" + $id,"Upload Photo",
    "menubar=no,width=430,height=100,toolbar=no");
});

此代码适用于 Firefox 和 Chrome.它不适用于 IE7 或 IE8(尚未测试 IE6).IE 在 window.open 行上弹出错误.为什么?IE 给出的错误是无效参数"，仅此而已.

This code works on Firefox and Chrome. It does not work on IE7 or IE8 (haven't tested IE6). IE pops up an error on the line window.open. Why? The error that IE gives is "Invalid Argument" and that's all.

推荐答案

导致它的第二个参数中的空格.如果您使用UploadPhoto"而不是Upload Photo"，它会起作用:

It's the space in the second parameter that's causing it. If you use "UploadPhoto" instead of "Upload Photo", it works:

$('#change_photo_link').click(function(){
    $id = $('#id').attr('value');

    window.open("photo.upload.php?id=" + $id,"UploadPhoto",
    "menubar=no,width=430,height=100,toolbar=no");
});

我似乎找不到任何官方原因来说明为什么 window.open() 的 windowName 参数中的空格会导致错误，但这很可能只是一个实现细节.windowName 用作内部引用，并且可以用作锚点或表单的目标属性的值，所以我猜 IE 无法在内部处理它.Gecko/Firefox 的参考文档说这个参数应该不包含空格，但显然 Gecko 的当前版本没有问题，如果有的话.

I can't seem to find any official reasons as to why having a space in the windowName parameter of window.open() causes an error, but it's likely just an implementation detail. The windowName is used as an internal reference, and can be used as a value for a target attribute of an anchor or form, so I guess IE can't handle that internally. The reference docs for Gecko/Firefox says that this parameter should not contain spaces, but clearly current versions of Gecko don't have a problem with it if it does.
