根据下面马克的回答用工作代码编辑。
我真的开始讨厌 MVC。我整天都在努力让一个简单的网格工作,但我更幸运的是我的头在我的桌子上敲了一个洞。
我正在尝试实现一个在网格中显示结果的搜索页面。用户可以使用 3 个下拉列表来选择搜索条件。他们必须至少选择一个。搜索后,用户将能够选择要导出的记录。所以我需要在生成的网格中包含复选框。这是未来的头痛。
使用JqGrid 和搜索表单 - ASP.NET MVC作为参考,我已经能够让网格出现在页面上(一项重大成就)。但是我无法获取要填充的数据。
顺便说一句,jqGrid 4.4.4 - jQuery 网格
这是我的看法:
@model Models.ExportDatex
<script type="text/javascript">
$(document).ready(function () {
$('#btnSearch').click(function (e) {
var selectedSchool = $('#ddlSchool').children('option').filter(':selected').text();
var selectedStudent = $('#ddlStudent').children('option').filter(':selected').text();
var selectedYear = $('#ddlYear').children('option').filter(':selected').text();
var selectedOption = $('#exportOption_1').is(':checked');
if (selectedSchool == '' && selectedStudent == '' && selectedYear == '') {
alert('Please specify your export criteria.');
return false;
}
selectedSchool = (selectedSchool == '') ? ' ' : selectedSchool;
selectedStudent = (selectedStudent == '') ? ' ' : selectedStudent;
selectedYear = (selectedYear == '') ? ' ' : selectedYear;
var extraQueryParameters = {
school: selectedSchool,
student: selectedStudent,
year: selectedYear,
option: selectedOption
};
$('#searchResults').jqGrid({
datatype: 'json',
viewrecords: true,
url: '@Url.Action("GridData")?' + $.param(extraQueryParameters),
pager: '#searchResultPager',
colNames: ['SchoolID', 'Student Name', 'Student ID', 'Apprenticeship', 'Result'],
colModel: [
{ name: 'SchoolID' },
{ name: 'Student Name' },
{ name: 'StudentID' },
{ name: 'Apprenticeship' },
{ name: 'Result' }]
}).trigger('reloadGrid', [{ page: 1 }]);
});
});
</script>
@using (Html.BeginForm("Index", "Datex", FormMethod.Post))
{
<h2>Export to Datex</h2>
<div class="exportOption">
<span>
@Html.RadioButtonFor(model => model.ExportOption, "true", new { id = "exportOption_1" })
<label for="exportOption_1">VET Results</label>
</span>
<span>
@Html.RadioButtonFor(model => model.ExportOption, "false", new { id = "exportOption_0" })
<label for="exportOption_0">VET Qualifications</label>
</span>
</div>
<div class="exportSelectionCriteria">
<p>Please specify the criteria you want to export data for:</p>
<table>
<tr>
<td>School:</td>
<td>@Html.DropDownListFor(model => model.SchoolID, Model.Schools, new { id = "ddlSchool" })</td>
</tr>
<tr>
<td>Student: </td>
<td>@Html.DropDownListFor(model => model.StudentID, Model.Students, new { id = "ddlStudent" })</td>
</tr>
<tr>
<td>Year Completed:
</td>
<td>
@Html.DropDownListFor(model => model.YearCompleted, Model.Years, new { id = "ddlYear" })
</td>
</tr>
</table>
<table id="searchResults"></table>
<div id="searchResultPager"></div>
</div>
<div class="exportSearch">
<input type="button" value="Search" id="btnSearch" />
<input type="submit" value="Export" id="btnExport" />
</div>
}
这是我的控制器。由于我们还没有数据库,我只是在使用来自不同数据库的现有表来提供记录 ID 的同时对一些结果进行硬编码。
[HttpGet]
public JsonResult GridData(string sidx, string sord, int? page, int? rows, string school, string student, string year, string option)
{
using (SMIDbContainer db = new SMIDbContainer())
{
var ds = (from sch in db.SCHOOLs
where sch.Active.HasValue
&& !sch.Active.Value
&& sch.LEVEL_9_ORGANISATION_ID > 0
select sch).ToList();
var jsonData = new
{
total = 1,
page = 1,
records = ds.Count.ToString(),
rows = (
from tempItem in ds
select new
{
cell = new string[]{
tempItem.LEVEL_9_ORGANISATION_ID.ToString(),
tempItem.SCHOOL_PRINCIPAL,
"40161",
"No",
"Passed (20)"
}
}).ToArray()
};
return Json(jsonData, JsonRequestBehavior.AllowGet);
}
}
