DOM:window.showModalDialog

Summary

Creates and displays a modal dialog box containing a specified HTML document.

Syntax

returnVal = window.showModalDialog(uri[, arguments][, options]);

where

  • returnVal is a variant, indicating the returnValue property as set by the window of the document specified by uri.
  • uri is the URI of the document to display in the dialog box.
  • arguments is an optional variant that contains values that should be passed to the dialog box; these are made available in the window object's window.dialogArguments property.
  • options an optional string that specifies window ornamentation for the dialog box, using one or more semicolon delimited values:
Syntax Description
center: {on | off | yes | no | 1 | 0 } If this argument's value is on, yes, or 1, the dialog window is centered on the desktop; otherwise it's hidden. The default value is yes.
dialogheight: height Specifies the height of the dialog box; by default, the size is specified in pixels.
dialogleft: left Specifies the horizontal position of the dialog box in relation to the upper-left corner of the desktop.
dialogwidth: width Specifies the width of the dialog box; by default, the size is specified in pixels.
dialogtop: top Specifies the vertical position of the dialog box in relation to the upper-left corner of the desktop.
resizable: {on | off | yes | no | 1 | 0 } If this argument's value is on, yes, or 1, the dialog window can be resized by the user; otherwise its size is fixed. The default value is no.
scroll: {on | off | yes | no | 1 | 0 } If this argument's value is on, yes, or 1, the dialog window has scroll bars; otherwise its size is fixed. The default value is no.

Note: Firefox does not implement the dialogHide, edge, status, or unadorned arguments.

Compatibility

Introduced by Microsoft Internet Explorer 4. Support added to Firefox in Firefox 3, and to Safari in Safari 5.1.

Examples

Try out showModalDialog().

Notes

showModalDialog() is currently being standardized as part of HTML5. The third argument (for additional options) is not present in the HTML5 version, and is (safely) ignored by both Safari and Chrome.
