Examples and usage of window.open and parameter descriptions

Window

　　First, window.open () Support environment:

javascript1.0+/jscript1.0+/nav2+/ie3+/opera3+

　　Second, the basic grammar:

window.open (Pageurl,name,parameters)

which

Pageurl for the child window path name for the child window handle parameters for window parameters (comma-delimited arguments)

　　Third, the example:

<SCRIPT>
<!--
window.open (' page.html ', ' newwindow ', ' Height=100,width=400,top=0,left=0,toolbar=no,menubar=no,scrollbars=no, Resizable=no,location=no, Status=no ')
Write a line
-->
</SCRIPT>

After the script is run, the page.html will open in the new form NewWindow, the width is 100, the height is 400, from the screen top 0 pixels, the screen left 0 pixels, no toolbar, no menu bar, no scroll bar, not adjustable size, no address bar, no status bar.

Please compare. There are a number of other parameters that are commonly used in the example above, see Four.

　　Four, the parameters

　　Example Description:

"1, the most basic pop-up window code"

In fact, the code is very simple:

<script language= "JavaScript" >
<!--
window.open (' page.html ')
-->
</SCRIPT>

Because it's a javascripts code, they should be placed between <script language= "JavaScript" > tags and </script>. <!--and--> are useful for some versions of browsers that do not display the code in the label as text in these old browsers. To develop this good habit ah.

window.open (' page.html ') is used to control the pop-up of the new window page.html, if page.html is not in the same path as the main window, before the path, absolute path (http://) and relative path (...) should be specified. /) are available. Both single and double quotes are OK, just don't mix.

This piece of code can be added anywhere in HTML,

"2, after the Set pop-up window"

Let's say a pop-up window setting. Just add something to the code above. Let's customize the appearance of this pop-up window, size, and popup position to fit the page's specifics.

<script language= "JavaScript" >
<!--
window.open (' page.html ', ' newwindow ', ' height=100, width=400, top=0,left=0, Toolbar=no, Menubar=no, Scrollbars=no, Resizable=no,location=no, Status=no ')
Write a line
-->
</SCRIPT>

Parameter explanation:

<script language= "javascript" > JS script started;
window.open the command to eject a new window;
The filename of the ' page.html ' pop-up window;
' NewWindow ' pop-up window name (not filename), not required, available null ' instead;
height=100 window height;
width=400 window width;
The pixel value of the Top=0 window from the top of the screen;
The pixel value of the left=0 window from the left side of the screen;
Toolbar=no whether the toolbar is displayed, yes for display;
Menubar,scrollbars represents the menu bar and scroll bar.
Resizable=no whether to allow changes to the window size, yes to allow;
Location=no whether the address bar is displayed, yes is allowed;
Status=no whether the information in the status bar is displayed (usually the file is open), yes to allow;
</SCRIPT> JS script End

"3, control pop-up window with function"

The following is a complete code.
<script language= "JavaScript" >
<!--
function Openwin () {window.open ("page.html", "NewWindow", "height=100, width=400, toolbar=
No, Menubar=no, Scrollbars=no, Resizable=no, Location=no, Status=no ")
Write a line
}
-->
</script>
<body >
... Any page content ...
</body>

A function Openwin () is defined here, and the function content is to open a window. There is no use before calling it.
How to call it?

Method One: <body > Browser pop-up window when reading the page;
Method Two: <body onunload= "Openwin ()" > Browser out of the page pop-up window;
Method Three: Call with a connection:

<a href= "#" > Open a Window </a>

Note: The "#" used is a virtual connection.

Method Four: Use a button to invoke:

<input type= "button" value= "open Window" >

"4, pop-up 2 windows at the same time"

Change the source code a little bit:

<script language= "JavaScript" >
<!--
function Openwin ()
{window.open ("page.html", "NewWindow", "height=100, width=100, Top=0,left=0,toolbar=no, Menubar=no, Scrollbars=no, Resizable=no, Location=no, Status=no ")
Write a line
window.open ("page2.html", "NewWindow2", "height=100, width=100, top=100, Left=100,toolbar=no, Menubar=no, scrollbars= No, Resizable=no, Location=no, Status=no ")
Write a line
}
-->
</script>

To avoid the 2 windows that pop up, use top and left to control the pop-up positions without overwriting each other. The last four methods mentioned above can be invoked.

Note: The name of the 2 windows (NewWindows and NewWindow2) is not the same, or simply all empty. Ok?

"5, the main window to open the file 1.htm, while pop-up small Windows page.html"

The following code is added to the main window <script language= "JavaScript" >
<!--
function Openwin ()
{window.open ("page.html", "", "width=200,height=200")
}
-->
</script>

Join <body> Area:

<a href= "1.htm" >open</a> can be.

"6, pop-up window of the timing off control"

Below we have some control of the pop-up window, the effect is better. If we add a small piece of code to the pop-up page (note is added to the page.html HTML, not the main page, otherwise ...), let it automatically shut down in 10 seconds is it cooler?

First, add the following code to the

<script language= "JavaScript" >
function Closeit ()
{settimeout ("self.close ()", 10000) file://milliseconds}
</script>

Then, then use <body > This sentence to replace page.html in the middle of some <BODY> this sentence on it. (Don't forget to write this sentence!) The function of this sentence is to call the code that closes the window, and then close the window itself after 10 seconds.

"7, add a Close button in the pop-up window"

<FORM>
<input type= ' BUTTON ' value= ' close ' >
</FORM>

Oh, now more perfect!

"8, included pop-up window-one page two windows"

The example above contains two windows, one is the main window and the other is a pop-up window.

With the example below, you can do the above in one page.

<script language= "JavaScript" >
function Openwin ()
{Openwindow=window.open ("", "Newwin", "height=250, width=250,toolbar=no,scrollbars=" +scroll+ ", Menubar=no");
Write a line
OpenWindow.document.write ("<TITLE> example </TITLE>")
OpenWindow.document.write ("<body bgcolor= #ffffff >")
OpenWindow.document.write ("OpenWindow.document.write ("New window opened!")
OpenWindow.document.write ("</BODY>")
OpenWindow.document.write ("</HTML>")
OpenWindow.document.close ()}
</SCRIPT>
<body>
<a href= "#" > Open a Window </a>
<input type= "button" value= "open Window" >
</body>

Look at the code inside OpenWindow.document.write () is not standard HTML? Just write more lines in the format. Be sure to pay attention to one more label or one less label will cause errors. Remember to end with OpenWindow.document.close ().

"9, the Ultimate application-pop-up window of the cookie control"

Recall that the above pop-up window, although cool, but there is a little trouble (immersed in joy, must not find it?) For example, you put the above script in a page that needs to go through frequently (for example, the first page), then each refresh this page, the window will pop up once, is not very annoying? Is there a solution to:-(? yes! ;-) Follow me.

We can use cookies to control it.

First, add the following code to the <HEAD> area of the homepage HTML:

<script>
function Openwin ()
{window.open ("page.html", "", "width=200,height=200")}
function Get_cookie (Name)
{var search = Name + ' = '
var returnvalue = "";
if (Document.cookie.length > 0) {
offset = document.cookie.indexOf (search)
if (offset!=-1) {
Offset + = Search.length
End = Document.cookie.indexOf (";", offset);
if (end = = 1)
end = Document.cookie.length;
Returnvalue=unescape (document.cookie.substring (offset,end))
}
}
Return returnvalue;
}
function Loadpopup () {
if (Get_cookie (' popped ') = = ") {
Openwin ()
Document.cookie= "Popped=yes"
}
}
</script>

Then, with <body > (note not openwin but Loadpop Ah!) Replace the main page in the original <BODY> this sentence can be. You can try to refresh the page or re-enter the page, and the window will never pop again. The real pop-only-once!.

Written here pop-up window of the production and application skills are basically completed, I am also tired, said so much, I hope to be making a friend of the Web site to help me very relieved.

Note that the capitalization in the JS script is best kept consistent.
