書上的例子﹐不知對你有沒有用
<HTML>
<HEAD>
<TITLE>Window Focus() and Blur()</TITLE>
<SCRIPT LANGUAGE="JavaScript1.1">
// declare global variable name
var newWindow = null
function makeNewWindow() {
// check if window already exists
if (!newWindow || newWindow.closed) {
// store new window object in global variable
newWindow = window.open("","","width=250,height=250")
// pause briefly to let IE3 window finish opening
setTimeout("fillWindow()",100)
} else {
// window already exists, so bring it forward
newWindow.focus()
}
}
// assemble new content and write to subwindow
function fillWindow() {
var newContent = "<HTML><HEAD><TITLE>Another Sub Window</TITLE></HEAD>"
newContent += "<BODY bgColor='salmon'>"
newContent += "<H1>A Salmon-Colored Subwindow.</H1>"
newContent += "<FORM><INPUT TYPE='button' VALUE='Bring Main to Front' onClick='self.opener.focus()'>"
newContent += "<FORM><INPUT TYPE='button' VALUE='Put Me in Back' onClick='self.blur()'>"
newContent += "</FORM></BODY></HTML>"
// write HTML to new window document
newWindow.document.write(newContent)
newWindow.document.close()
}
