js中实现子页面向父页面中赋值（两种方法）
? (方法一)
父页面:<input id="input1" type="text"/><a href="javascript:window.open('test1.aspx');void(0)">弹出新的子窗口</a>子页面:<input id="input2" type="text" /><input id="bt" type="button" onclick="doit();" value="更新父窗口的内容"/><script type="text/javascript" language="javascript">function doit(){ var _value=document.getElementByIdx('input2').value; window.opener.document.getElementByIdx('input1').value=_value;}</script>?
(方法二)
父页面:<input id="input1" type="text" /><a href="javascript:GetReturnValue();void(0)">弹出新的模态子窗口</a><script type="text/javascript" language="javascript"> function GetReturnValue() { var temp= window.showModalDialog("test1.aspx","","center=yes;help=no;status=no"); document.getElementByIdx('input1').value = temp; }</script>子页面:<input id="input2" type="text" /><input id="bt" type="button" onclick="doit();" value="更新父窗口的内容"/><script type="text/javascript" language="javascript">function doit(){ var _value=document.getElementByIdx('input2').value; window.returnValue =_value; window.close();}</script>?
