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>
