三、Javascript模态对话框 取父页的值
1. a.htm 父页
有 window.showModalDialog("b.htm");
有 Html元素 <input type="text" value="value">
2.b.htm 弹出页面
能否在 b.htm 上取到 a.htm 中 t1值 ?
回答:
在a.html中设置
var results = window.showModalDialog("b.html");
(results){alert(results["key"]);}
在b.html中
<script>
window.Value={key:"返回到父页面"}
</script>
四、模态对话框模仿MessageBox
复制代码 代码如下:
