js creates a child window and returns a value sample code_javascript skills

Copy can be used directly, dear friends!

Copy code The code is as follows:

//Parent window
function onClick(){
var k = showModalDialog(
"view/WriteKey.jsp", contained page
"newwindow", fixed value
"dialogHeight:200px;
dialogWidth:400px; width
toolbar:no; whether there is a toolbar
menubar:no; whether there is a menu bar
scrollbars:no; scroll bar
resizable:no;
location:no ; Address bar
status:no; Status bar
left:100px;
top:100px;"); Alas, there are still two attributes I don’t remember, go to Baidu to download them.
//K is the value returned by the window
//Judge k
if(k!=null&&typeof(k)!=undefined){
..... ..........ok
}
}
//Sub window "view/WriteKey.jsp

JS part
function trans(tag){
var s=document.getElementById("dy").value document.getElementById("keyZ").value;
window.returnValue=s;
window.close();
}

ok, done,
