oNewWindow=window.open([sURL] [, sName] [, sFeatures] [, bReplace])ParameterssURL Optional. String that specifies the URL of the document to display. If no URL is specified, a new window with about:blank is displayed.
sName Optional. String that specifies the name of the window. This name is used as the value for the TARGET attribute on a FORM or an A element.
In Internet Explorer 5 and later, specifying the value _search opens sURL in the browser's search pane.
sFeatures Optional. String that specifies the window ornaments to display. The following features are supported: channelmode = { yes | no | 1 | 0 } Specifies whether to display the window in theater mode and show the channel band. The default is no.
directories = { yes | no | 1 | 0 } Specifies whether to add directory buttons. The default is yes.
fullscreen = { yes | no | 1 | 0 } Specifies whether to display the browser in a full-screen or normal window. The default is no, which displays the browser in a normal window.
Use full-screen mode carefully. Because this mode hides the browser's title bar and menus, you should always provide a button or other visual clue to help the user close the window. ALT+F4 also closes the new window.
height = number Specifies the height of the window, in pixels. The minimum value is 100.
left = number Specifies the left position, in pixels. This value is relative to the upper-left corner of the screen.
location = { yes | no | 1 | 0 } Specifies whether to display the input field for entering URLs directly into the browser. The default is yes.
menubar = { yes | no | 1 | 0 } Specifies whether to display the menu bar. The default is yes.
resizable = { yes | no | 1 | 0 } Specifies whether to display resize handles at the corners of the window. The default is yes.
scrollbars = { yes | no | 1 | 0 } Specifies whether to display horizontal and vertical scroll bars. The default is yes.
status = { yes | no | 1 | 0 } Specifies whether to add a status bar at the bottom of the window. The default is yes.
titlebar = { yes | no | 1 | 0 } Specifies whether to display a title bar for the window. This parameter is ignored unless the caller is an html application or a trusted dialog box. The default is yes.
toolbar = { yes | no | 1 | 0 } Specifies whether to display the browser toolbar, making buttons such as Back, Forward, and Stop available. The default is yes.
top = number Specifies the top position, in pixels. This value is relative to the upper-left corner of the screen.
width = number Sets the width of the window, in pixels. The minimum value is 100.
bReplace Optional. Boolean that specifies whether the URL that is loaded into the new page should create a new entry in the window's browsing history or replace the current entry in the browsing history. If set to true, no new history entry is created.
系统出问题了，比如ie有问题，可能调整一些设置什么得，就行了
代码从90%以上的机器上都没问题，就是有那么几台机器不行
其实，那些机器从前都是可以得，或者不知道访问了什么非法网站了
也或许，安装软件把系统的某些设置给改了
反正，就是window.open不起作用了，根本打不开窗口了我觉得，大可不必怀疑语句的错误，，，，
<!--
//检查用户输入，无误后提交
function checkuser()
{
//......
//省略了部分验证语句 var openwin=window.open("about:blank","main",""); //问题在这里，有的机器根本不执行这个 openwin.moveTo(0,0);
openwin.resizeTo(screen.width,screen.height-30);
document.logon.target="main";
document.logon.method="post";
document.logon.action="enter.php";
document.logon.submit();
document.logon.txt_password.value=""}
//-->
</script>其实，就是这么简单的一个函数，都很标准，没啥特殊的地方
这个问题的关键在于谁对ie的设置什么得比较熟悉
或者,window.open是否使用还有一些限制，内幕之类的大家跟贴啊，分不够，我再重新开贴！！！！！！！！！！！！！！
还有,谁能告诉我,第二个参数什么意思>??/计:本例中的""main,什么时候能用的照?在那里?
如果两个window.open使用同一个名字，那么这两个将使用同一个窗口
后面的窗口将再前面的打开的窗口中显示（覆盖）这样是不行的，我说过了，应该不是语句的问题
