MVC弹出子页面向父页面传值

实现思路是使用js在父子页面间传值

视图一代码，父页面

@{
    ViewBag.Title = "Index";
}

<script type="text/javascript">
    //alert("1");
    function test()
    {
        window.showModalDialog('test/listtest', 'newwindow', 'height=400,width=400,top=0,left=0,toolbar=no,menubar=no,scrollbars=no,resizable=yes,location=no, status=no')
        var temp = window.showModalDialog('test/listtest', 'newwindow', 'height=400,width=400,top=0,left=0,toolbar=no,menubar=no,scrollbars=no,resizable=yes,location=no, status=no')
        document.getElementById("test").value = temp;
    }
</script>

<h2>@ViewData["Message"]</h2>
<p><input type="submit" value="submit" onclick="test()"></p>
<p><input type="text" id="test"></p>

视图二代码：子页面

@model IEnumerable<mvctest.Models.student>

@{
    ViewBag.Title = "listtest";
}

<script type="text/javascript">
    function sendvalue(a) {
        alert(a);
        document.getElementById("test").value = a;
        window.returnValue = a;
        window.close();
    }
</script>
<p>
    <input type="submit" value="sendvalue" onclick="sendvalue()">
    <input type="text" id="test" value=sendvalue>
</p>

<h2>listtest</h2>

<p>
    @Html.ActionLink("Create New", "Create")
</p>
<table id="table1">
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.name)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.password)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.descript)
        </th>
        <th></th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.name)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.password)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.descript)
        </td>
        <td>
            <input type="button" value="haha" onclick="sendvalue('@item.name')">
        </td>
    </tr>

}
