【1. The most basic pop-up window code】

Actually the code is very simple:

Copy code The code is as follows:

Because it is a piece of javascripts code, they should be placed between the tag and . are effective for some older browsers. In these old browsers, the code in the tag will not be displayed as text. Develop this good habit.

Window.open('page.html') is used to control the pop-up of a new window page.html. If page.html is not in the same path as the main window, the path should be stated in front, the absolute path (http:// ) and relative paths (../) are available. You can use either single quotes or double quotes, just don't mix them.

This piece of code can be added anywhere in the HTML, between and , and between . The earlier it is, the earlier it will be executed, especially if the page code is long. , and if you want the page to pop up earlier, put it as far forward as possible.

【2. Pop-up window after setting】

Let’s talk about the settings of pop-up windows. Just add a little more to the code above.
Let’s customize the appearance, size, and pop-up position of this pop-up window to suit the specific conditions of the page.

<scrip tlanguage="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') //写成一行 --> </scrip>
[Ctrl A select all Note: If you need to introduce external Js, you need to refresh to execute ]

Parameter explanation:

js script starts;
window.open command to pop up a new window;
'page.html' pop-up window file name;
'newwindow' pop-up The name of the window (not the file name) is optional and can be replaced by an empty '';
height=100 window height;
width=400 window width;
top=0 pixel value from the top of the screen to the window ;
left=0 The pixel value of the window from the left side of the screen;
toolbar=no whether to display the toolbar, yes to display;
menubar, scrollbars represent the menu bar and scroll bar.
Resizable=no whether to allow changing the window size, yes is allowed;
location=no whether to display the address bar, yes is allowed;
status=no whether to display the information in the status bar (usually the file has been opened ), yes is allowed;
js script ends

【3. Use functions to control pop-up windows】

The following is a complete code

<scrip tlanguage="JavaScript"> <!-- function openwin(){window.open("page.html","newwindow","height=100,width=400,toolbar=no,menubar=no,scrollbars=no,resizable=no,location=no,status=no") //写成一行 } //--> <bodyonload> …arbitrary page content… </bodyonload></scrip>
