本文介绍如何使用window.showModalDialog方法实现父窗口与子窗口之间的数据传递。通过示例展示了参数设置、对话框特性配置及返回值处理等关键步骤。

2.window.showModalDialog()

vReturnValue = window.showModalDialog(sURL [, vArguments] [, sFeatures])

vArguments父窗口向子窗口传递参数；

vReturnValue子窗口向父窗口传递数据。

父窗口html

<div id="popup_2" align="center"><hr>
	<fieldset><legend>window.showModalDialog()</legend>
		<p><label for="name_2">名字:</label> <input type="text" name="name_2"></p>
		<p><label for="age_2">年龄:</label> <input type="text" name="age_2"></p>
