you Have 2 syntax errors, one in your onClick attribute, your about:blankisn't quoted
Two, in window.open you have +'at the end of you second argument also you have the third argument as a string, it should be boolean.
你有 2 个语法错误，一个在你的 onClick 属性中，你about:blank没有引用
两个，在 window.open 中，你有+'第二个参数的末尾，第三个参数是一个字符串，它应该是布尔值。

A unique bit of relevant trivia:
at least in recent releases of IE, 9.0.8112.16241 (vista/win7) and 8.0.6001.18072 (xp), programmatically do a window.open(‘about:blank')and the programmable focus()will be stuck in the address bar showing “about:blank”.
Note:window.open(”)with an empty string URL is the same as window.open(‘about:blank').
一个独特的相关琐事：
至少在最近版本的 IE、9.0.8112.16241 (vista/win7) 和 8.0.6001.18072 (xp) 中，以编程方式执行 awindow.open(‘about:blank')并且可编程focus()将卡在地址栏中显示“ about:blank” .
注意：window.open(”)带有空字符串的 URL 与window.open(‘about:blank').
Adding the option location=noworks around this based on IE security settingAllow websites to open windows without address or status bars
添加该选项location=no可根据 IE 安全设置解决此问题Allow websites to open windows without address or status bars
However they default badly (force address bar). Simplest I've found is to have users set our site in their security settings as “trusted” where the default “medium” settings do not force the address bar to show.
然而，它们的默认设置很糟糕（强制地址栏）。我发现的最简单的方法是让用户在他们的安全设置中将我们的站点设置为“受信任”，其中默认的“中等”设置不会强制显示地址栏。
Using a dummy URI javascript:popup=1in IE 8 did work around this, but that may open in a new tab based on settings which may not work for you.
javascript:popup=1在 IE 8 中使用虚拟 URI确实解决了这个问题，但它可能会根据可能不适用于您的设置在新选项卡中打开。
Relevant custom security setting:
相关自定义安全设置：
- Where: Tool->Internet Options->Security->Custom Level->Miscellaneous
- Value: Allow websites to open windows without address or status bars: enable
- 其中：工具->Internet 选项->安全->自定义级别->其他
- 值：允许网站打开没有地址栏或状态栏的窗口：启用
Note:mine is a legacy web based “application” that employs the legitimately useful design of popups which are beneficial (no one has ripped them out of “Word” yet). It is enough challenge for those of us damaged as this useful UI mechanism has been marred by scammers and hackers that I implore you to resist further beating us up with the non-productive “don't use popups” tangential interjection.
注意：我的是一个传统的基于网络的“应用程序”，它采用了合法有用的弹出窗口设计，这些设计是有益的（还没有人将它们从“Word”中删除）。对于我们这些受到损害的人来说，这是足够的挑战，因为这种有用的 UI 机制已被骗子和黑客破坏，我恳请您不要再用非生产性的“不要使用弹出窗口”切向感叹词来打击我们。

in html calling code,
在 html 调用代码中，
<input type="button" value="Open window" onclick="openWin('http://www.google.com', 200, 200)" />
in the url part you can have an either absolute url or relative one..
在 url 部分，您可以拥有绝对 url 或相对 url。
hope this helps..

Try this instead:
试试这个：
<input type="button"
value="Open window"
onclick="openWin('about:blank', 200, 200);" />
I think the colon in the URL param in your function call is causing the problem - if it's a string it should be in quotes.
我认为函数调用中 URL 参数中的冒号导致了问题 - 如果它是一个字符串，它应该用引号引起来。
EDIT: added a semi colon - this seems to work for me.
编辑：添加了一个分号 - 这似乎对我有用。

Your falseat the end of the w=window.open()line isn't properly quoted/concatenated.
您false在该w=window.open()行的末尾未正确引用/连接。
