为什么Firefox 6会忽略javascript window.open中的高度，宽度，顶部和左侧设置？ [英] Why is Firefox 6 ignoring my height, width, top and left settings in javascript window.open?
问题描述
这个函数的目的打开一个以屏幕为中心的800x600窗口，并在IE和Mozilla浏览器中以模态方式显示。
< html>
< head>
< script language =javascripttype =text / javascript>
函数openWindow（pageURL，Title，w，h）
{
var left =（screen.width / 2） - （w / 2）;
var top =（screen.height / 2） - （h / 2）;
if（window.showModalDialog）{
window.showModalDialog（pageURL，Title，'dialogWidth：'+ w +'px，dialogHeight：'+ h +'px，dialogTop：'+ top +'px ，dialogLeft：'+ left +'，resizable = no'）;
} else {
window.open（pageURL，Title，toolbar = no，location = no，directories = no，status = no，menubar = no，scrollbars = yes，resizable = no，modal = yes，copyhistory = no，width =+ w +，height =+ h +，top =+ top +，left =+ left）
}
}
< / script>
< / head>
< body>
< / body>
< / html>
为了澄清一下，函数被设计用来测试ShowModalDialog的存在（假定只有IE支持它），并落入适当的window.open分支在所有支持W3C的window.open命令，实现模式选项的一切。这个想法是，如果ShowModalDialog被实现，那么它会使用，否则使用window.open与Modal选项。
showModalDialog中的分号，而不是逗号：
< html>
< head>
< script language =javascripttype =text / javascript>
函数openWindow（pageURL，Title，w，h）
{
var left =（screen.width - w）/ 2;
var top =（screen.height - h）/ 2;
var options;
if（window.showModalDialog）{
options ='dialogwidth：'+ w +'; dialogheight：'+ h +'; dialogtop：'+ top +'; dialogleft：'+ left +';可调整大小=无';
console.log（options）;
window.showModalDialog（pageURL，Title，options）;
} else {
options =toolbar = no，location = no，directories = no，status = no，menubar = no，scrollbars = yes，resizable = no，modal = yes，copyhistory = no， width =+ w +，height =+ h +，top =+ top +，left =+ left;
console.log（window.open options：+ options）;
window.open（pageURL，Title，options）
}
}
< / script>
< / head>
< body>
< / body>
< / html>
Can anybody see what's wrong with my code? It behaves properly in IE but firefox 6 seems to ignore any height or width settings that I pass through to the javascript window.open call. I can't see anything obviously wrong with it but javascript isn't my first language so I may be making a noob error somewhere in this.
The purpose of this function is to open an 800x600 window centered on the screen and displayed modally in both IE and Mozilla family browsers.
<html>
<head>
<script language="javascript" type="text/javascript">
function openWindow(pageURL,Title,w,h)
{
var left = (screen.width/2)-(w/2);
var top = (screen.height/2)-(h/2);
if (window.showModalDialog) {
window.showModalDialog(pageURL,Title,'dialogWidth:' + w + 'px,dialogHeight:'+ h + 'px,dialogTop:'+ top + 'px,dialogLeft:' + left + ',resizable=no');
} else {
window.open(pageURL,Title,"toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=yes,resizable=no,modal=yes, copyhistory=no,width=" + w + ", height=" + h + ", top=" + top + ", left=" + left)
}
}
</script>
</head>
<body>
<a href="javascript:openWindow('http://www.google.com','Google',800,600);">Launch</a>
</body>
</html>
Just to clarify a bit, the function is designed to test for the presence of ShowModalDialog (presuming that only IE supported it) and fall into the proper window.open branch in everything that supports the W3C window.open command which implements the "Modal" option. The idea being that if ShowModalDialog was implemented then it would use that otherwise use the window.open with the "Modal" option.
Semi-colons, not commas, in showModalDialog:
<html>
<head>
<script language="javascript" type="text/javascript">
function openWindow(pageURL,Title,w,h)
{
var left = (screen.width - w) / 2;
var top = (screen.height - h) / 2;
var options;
if (window.showModalDialog) {
options = 'dialogwidth:' + w + ';dialogheight:'+ h + ';dialogtop:'+ top + ';dialogleft:' + left + ';resizable=no';
console.log(options);
window.showModalDialog(pageURL, Title, options);
} else {
options = "toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=yes,resizable=no,modal=yes, copyhistory=no, width=" + w + ", height=" + h + ", top=" + top + ", left=" + left;
console.log("window.open options: " + options);
window.open(pageURL, Title, options)
}
}
</script>
</head>
<body>
<a href="javascript:openWindow('http://www.google.com','Google',800,600);">Launch</a>
</body>
</html>
