Avoid the Cause Analysis of the new form displayed in showModalDialog _ javascript skills

Avoid the Cause Analysis of the new form displayed in showModalDialog. Generally, you need to use window. open. showModalDialog and showModelessDialog to return the value.

1. What are the differences between showModalDialog and showModelessDialog?

4. How to use javascript to turn off the window opened by showModalDialog (or showModelessDialog.

Must also be used together Otherwise, a new IE window will be opened and closed.

5. Data Transmission skills of showModalDialog and showModelessDialog.
(Author's note: I wanted to write it in the form of a question and answer, but I couldn't figure out how to ask this, so I had .)
This is troublesome. I have changed it several times, but I cannot explain it in the white space (the language level is getting worse and worse). I have to explain it in an example.
Example:
Now you need to read or set a variable var_name in a showModalDialog (or showModelessDialog ).

General transfer method:
Window. showModalDialog ("filename.htm", var_name)
// Pass the var_name variable
When showModalDialog (or showModelessDialog) is read and set:
Alert (window. dialogArguments) // read the var_name variable
Window. dialogArguments = "oyiboy" // set the var_name variable
This method can be met, but what if you want to operate var_name and then change var_id? No

Then perform the operation. This is the limitation of this transfer method.

The following is the recommended transfer method:
Window. showModalDialog ("filename.htm", window)
// No matter what variables you want to operate, only the window object of the main window is passed directly.
When showModalDialog (or showModelessDialog) is read and set:
Alert (window. dialogArguments. var_name) // read the var_name variable
Window. dialogArguments. var_name = "oyiboy" // set the var_name variable

You can also operate the var_id variable.
Alert (window. dialogArguments. var_id) // read the var_id variable
Window. dialogArguments. var_id = "001" // set the var_id variable

You can also operate any object in the main window, such as the elements in the form object.
Window. dialogArguments. form1.index1. value = "this is the value of the index1 element"

6. Multiple showModelessDialog operations.
Because it is very difficult to say, I will be a little lazy and use the Code directly. If I don't understand it, I will send a letter directly (oyiboy # 163.net (

Change # To @) to ask me.

The main function of the following code is to move another showModelessDialog location in a showModelessDialog.

Some js Code of the main file.
Var s11_showmodelessdialog('control .htm' ', window, "dialogTop: 1px; dialogLeft: 1px") // Open Control

Create window
Var s2 = showModelessDialog (''about: blank '', window," dialogTop: 200px; dialogLeft: 300px ")

// Open the controlled window

Control some code of .htm.
Script
// Operation location data. This special operation function is required because the window location data is in the "xxxpx" mode.
Function countNumber (A_strNumber, A_strWhatdo)
{
A_strNumber = A_strNumber.replace (''px '','''')
A_strNumber-= 0
Switch (A_strWhatdo)
{
Case "-": A_strNumber-= 10; break;
Case "+": A_strNumber + = 10; break;
}
Return A_strNumber + "px"
}
Script





The above key parts are:
Window naming method: var s1 = showModelessDialog (''Control

Create .htm'', window, "dialogTop: 1px; dialogLeft: 1px ")
Variable access method: window. dialogArguments. s2.dialogTop

This example is just about the location operation between showModelessDialog and showModelessDialog,

The showModelessDialog interface controls each other's display pages and transmits variables and data. It depends on your efforts.

If you open a mode window and want to close the window and reload the parent window in the window, the Code is as follows:
