Я хочу загрузить jqGrid при нажатии кнопки в MVC 3, но я не могу это сделать.Данные поступают нормально, но на странице ничего не происходит.Когда я нажимаю, он показывает загрузку сетки, но потом, когда ничего не происходит.Пожалуйста, смотрите следующее:
My View
@{
ViewBag.Title = "Home";
}
@section Javascript
{
<script type="text/javascript">
var jqDataUrl = "LoadCustomerData";
$(document).ready
(
function () {
$('#btnContinue').live('click', function () {
bindCustomers();
});
}
);
var bindCustomers = function () {
alert('in');
// Set up the jquery grid
$("#jqTable").jqGrid
(
{
// Ajax related configurations
url: jqDataUrl,
datatype: "json",
mtype: "POST",
// Specify the column names
colNames: ["CustomerId", "FirstName", "LastName"],
// Configure the columns
colModel: [
{ name: "CustomerId", index: "CustomerId", width: 40, align: "left" },
{ name: "FirstName", index: "FirstName", width: 100, align: "left" },
{ name: "LastName", index: "LastName", width: 200, align: "left"}],
// Grid total width and height
width: 550,
height: 200,
// Paging
toppager: true,
pager: $("#jqTablePager"),
rowNum: 5,
rowList: [5, 10, 20],
viewrecords: true, // Specify if "total number of records" is displayed
// Default sorting
//sortname: "Id",
//sortorder: "asc",
// Grid caption
caption: "A Basic jqGrid - Read Only"
}
).navGrid("#jqTablePager",
{ refresh: true, add: false, edit: false, del: false },
{}, // settings for edit
{}, // settings for add
{}, // settings for delete
{sopt: ["cn"]} // Search options. Some options can be set on column level
);
alert('loading finish');
}
</script>
}
