We often need to do a pop-up window on the home page (in fact I hate this stuff), the general approach is to add such a onload= in <body> "window.open (' new-window.htm ', ', ', ' width=300, height=250 ') " Where new-window.htm is the file name of the newly opened window page, the back page is width and height, but if it is a will to this window, a will not, and often change the contents of this window, that is really the wife trouble (Ayu head so, gas dead me, one day unexpectedly changed n times, so that Dmitri Trenin, wrote this small program).
Basic ideas:
1. To do such a program, the key is to accurately find <body> mark on the home page, and in which add onload= "window.open (' new-window.htm ', ', ', ' width=300,height=250 ')", To become <body onload= "window.open (' new-window.htm ', ', ' width=300,height=250 ')", how can we find <body>? Through observation found that the entire home page on a <body>, using the INS function to find <body> in the page starting position plus five to get the position of the statement should be inserted. Of course, you also have to be able to delete onload= "window.open (' new-window.htm ', ', ', ' width=300,height=250 ')", which is to delete the sentence from "<body" to "" "" ", To undo the pop-up window, I found that there is only one "'" in the page, and the first one to look back at least from the first is what we want "".
2. To create a file, named New-window.htm, this is relatively simple, look at the following code to know.
Production process:
With the idea, we started the next.
First, make a page of input parameters, file name, newwindow.asp on this page, there are six text boxes, the first name to enter the window name, the second name is Co1, to fill out the page background, the third name is CO2 to fill in the text color, the fourth name is BG, Used to fill in the bottom chart file name, the fifth name is W, to fill out the width of the pop-up window, the fifth named H, to fill out the width of the pop-up window. Also, a scrolling text box named LR is used to fill in the content to be published in the pop-up window. Create three more buttons, the first is to create a pop-up window, the second is a preview, the third is the Undo pop-up window, the button type is submitted, the name is B1,B2,B3 respectively. After the form is submitted by the newwindow1.asp file, the code for the file is as follows (you can also write yourself as described above):
<!--#include file= "Window.ini"-->
<title> Excellent computer website Express www.zydn.net</title>
<body bgcolor= "#E0F0F8" >
<div align= "center" >

Insert a file Newwindow.ini in the front, this file is used to record the last number you entered the parameters, the first time you use, as long as the file to fill in a few spaces.
Before the page input parameters submitted by the newwindow1.asp file to deal with, while we look at this file, while to explain the role of each sentence,
FileName: newwindow.asp, full text as follows:
<%patha=server. MapPath ("newwindow1.asp")
Patha=left (Patha,len (Patha)-14) ' * * * The above two are used to get the path where the file is located so that the file SystemObject object that is established by the file access component can then be read and created.
