5. Modal and non-modal windows

The window.showModalDialog () method is used to create a modal dialog box that displays HTML content.
The Window.showmodelessdialog () method is used to create a non-modal dialog box that displays HTML content.

How to use:

Vreturnvalue = window.showModalDialog (sURL [, varguments] [, Sfeatures])
Vreturnvalue = Window.showmodelessdialog (sURL [, varguments] [, Sfeatures])

Parameter description:

sURL --Required parameter, type: String. Used to specify the URL of the document to be displayed by the dialog box.

varguments --optional parameter, type: Variant. Used to pass parameters to the dialog box. There are no limits on the types of arguments passed, including arrays. The dialog box uses window.dialogarguments to get the arguments passed in.

sfeatures --optional parameter, type: String. Used to describe the appearance of the dialog box and other information, you can use the following one or several, with a semicolon ";" Separated.

----------------
1. Dialogheight: Height of dialog box, not less than 100px
2. Dialogwidth: Width of the dialog box.
3. Dialogleft: Distance from the left of the screen.
4. Dialogtop: Distance from the screen.
5. Center: {yes | no | 1 | 0}: Center, default yes, but can still specify height and width.
6. Help: {yes | no | 1 | 0}: Whether to display the Assist button, default yes.
7. Resizable: {yes | no | 1 | 0} [ie5+]: Whether the size can be changed. Default No.
8. Status:{yes | no | 1 | 0} [ie5+]: Whether the status bar is displayed. Default is yes[Modeless] or no[modal].
9. scroll:{Yes | no | 1 | 0 | on | off}: Scroll bar is displayed. The default is yes.

Parameter passing:

1. To pass a parameter to a dialog box, pass it through varguments. Type is not limited, for string types, the maximum is 4,096 characters. You can also pass objects, for example:

<script>
var obj = new Object ();
Obj.name= "51js";
window.showModalDialog ("modal.htm", obj, "dialogwidth=200px;dialogheight=100px");
</script>
Modal.htm
<script>
var obj = window.dialogarguments
Alert ("You passed the parameter:" + obj.name)
</script>

2. You can return information by Window.returnvalue to the window that opens the dialog box, or it can be an object. For example:

<script>
Str =window.showmodaldialog ("modal.htm",, "dialogwidth=200px;dialogheight=100px");
alert (str);
</script>
Modal.htm
<script>
Window.returnvalue= "Http://www.jb51.net";
</script>
