[原]js中实现子页面向父页面中赋值

(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" οnclick="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" οnclick="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>
