我的目标是让输入文本框有两个按钮,这些按钮将使用输入执行不同的数据库查询,然后将结果输出到Kendo Grid。有人可以给我一个例子或指出我做错了什么吗?我想使用Ajax,因为从我有限的理解,这将阻止整页重新加载。
查看代码:
<div class="loginForm">
<div id="searchForm" class="well">
<h2>Search</h2>
<form method="post" action="~/Search/Search">
<input type="text" id="search" name="input" class="form-control input-group input-group-lg" placeholder="Search..." required autofocus/>
<br />
<input type="submit" id="bunNumBut" name="submitBut" class="btn btn-primary btn-sm pull-left" value="Bundle Number" />
<input type="submit" id="custNumBut" name="submitBut" class="btn btn-primary btn-sm pull-right" value="Customer Number" />
</form>
</div>
</div>
<br />
<div>
{
@(Html.Kendo().Grid(Model)
.Name("searchResultsG")
.Columns(columns =>
{
columns.Bound(c => c.BundleNumber);
columns.Bound(c => c.CustomerNumber);
columns.Bound(c => c.Carrier);
columns.Bound(c => c.Active);
})
.Pageable(pageable => pageable
.Refresh(true)
.PageSizes(true)
.ButtonCount(5))
.Sortable()
.Editable()
.DataSource(dataSource => dataSource
.Ajax()
.Read(read => read
.Action("Bundles_Read", "Search")
.Data("bundlesReadData"))
.Model(model => model.Id(p => p.CustomerNumber)))
)
}
</div>
<script>
function bundlesReadData() {
return {
input: $('#search').val()
};
}
</script>
控制器代码:
[HttpPost]
public ActionResult Search(string input, string submitBut)
{
searchInput = input; //private class variables, but they get erased on each request
submitButton = submitBut; //private class variables, but they get erased on each request
switch (submitButt)
{
case "Bundle Number":
return View("Index");
case "Customer Number":
return View("Index");
default:
return View("Index");
}
}
public ActionResult Bundles_Read([DataSourceRequest]DataSourceRequest request)
{
if (searchInput == "Bundle Number")
return Json(GetBundlesByBunNum(searchInput).ToDataSourceResult(request));
else
return Json(GetBundlesByCustNum(searchInput).ToDataSourceResult(request));
}
我不知道如何将输入和submitBut传递给javascript函数bundlesReadData(),因为我想将条件数据传递给Bundles_Read()方法。我也不知道这个DataSourceRequest对象在做什么,它阻止我在我的Search()方法中调用GetBundlesByBunNum()和GetBundlesByCustNum()方法。如果有什么不清楚,或者我需要提供更多细节来帮助您,请告诉我。

如果您已经返回了所有数据,那么您可以在单个文本框中使用kendo的过滤功能,而不是发送额外的ajax请求来过滤结果。
当用户在文本框字段中输入内容时,如果BundleNumber或CustomerNumber包含用户输入字段值,则网格会过滤搜索结果。
<div class="loginForm">
<div id="searchForm" class="well">
<h2>Search</h2>
<input type="text" id="search" name="input" class="form-control input-group input-group-lg" placeholder="Search..." required autofocus/>
</div>
</div>
<script type="text/javascript">
$(function()
{
$('#search').on('input', function()
{
var value = $(this).val();
if (value)
{
$("#searchResultsG").data("kendoGrid").dataSource.filter(
{
logic: "or",
filters:
[
{ field: "BundleNumber", operator: "contains", value: value },
{ field: "CustomerNumber", operator: "contains", value: value }
]
});
}
else
{
$("#searchResultsG").data("kendoGrid").dataSource.filter({});
}
});
});
</script>
