我对 ASP.NET 很陌生,对 Javascript 也很陌生。我正在编写一个 ASP.NET 用户控件。我有以下内容:
<head>
<title>Select Asset </title>
<script src="../Scripts/jquery-1.9.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
function CheckThenCloseActiveToolTip(supplierID) {
var radGrid = $find('ctl00_MainContent_SelectAssetGrid1_gridAssetList_ctl00');
var selectedItems = radGrid.get_masterTableView().get_selectedItems()
if (selectedItems == null || selectedItems.length == 0) return 'You must select an asset first';
else {
DoPartialPostBack('selectasset', selectedItems[0]._dataItem.Id);
CloseActiveToolTip();
}
}
function PopulateRooms(e) {
var idx = e.selectedIndex;
if (idx > -1) {
var dcId = JSON.stringify({ dataCenterId: e.options[idx].value });
var pageUrl = '/WebService/AVWebService.asmx';
$.ajax({
url: pageUrl + '/GetRooms',
type: 'post',
contentType: 'application/json; charset=utf-8',
dataType: 'json',
data: dcId,
success: OnRoomsReceived,
error: OnErrorCall
});
}
else {
var ddlRooms = document.getElementById('MainContent_SelectAssetGrid1_ddlRooms');
ddlRooms.disabled = true;
$('#ddlRooms').empty();
ddlRooms.options[0] = new Option('', '-1');
getAssets(0);
}
}
function OnRoomsReceived(result) {
var ddlRooms = document.getElementById('MainContent_SelectAssetGrid1_ddlRooms');
if (result.d.length > 0) {
ddlRooms.disabled = false;
$('#ddlRooms').empty();
ddlRooms.options[0] = new Option('', '-1');
for (var i = 0; i < result.d.length; i++) {
ddlRooms.options[i + 1] = new Option(result.d[i].Name, result.d[i].Id);
}
}
if (result.d.length = 1)
ddlRooms.selectedIndex = 1;
getAssets(0);
}
function resetGridData() {
getAssets(0);
}
function getAssets(startAt) {
var cpId = document.getElementById('hfldCompanyId').value;
var pageUrl = '/WebService/AVWebService.asmx';
var tableView = $find('ctl00_MainContent_SelectAssetGrid1_gridAssetList').get_masterTableView();
var ddldc = document.getElementById('MainContent_SelectAssetGrid1_ddlDataCenter');
var dcIdx = ddldc.selectedIndex;
var dcId = '';
if (dcIdx > -1)
dcId = ddldc.options[dcIdx].value;
var ddlrm = document.getElementById('MainContent_SelectAssetGrid1_ddlRooms');
var rmIdx = ddlrm.selectedIndex;
var rmId = '';
if (rmIdx > -1)
rmId = ddlrm.options[rmIdx].value;
var ddlStatuses = $find('ctl00_MainContent_SelectAssetGrid1_ddlStatuses';
var rbgAssetClass = document.getElementById('MainContent_SelectAssetGrid1_rbgAssetClass');
var ac = 0;
var rbgInputs = rbgAssetClass.getElementsByTagName('input');
for (var i = 0; i < rbgInputs.length; i++) {
if (rbgInputs[i].checked) {
ac = i;
}
}
var filters = [];
var fbs = document.getElementsByClassName('rgFilterBox');
for (var i = 0; i < fbs.length; i++)
if (fbs[i].value != '')
filters[filters.length] = { field: fbs[i].alt, value: fbs[i].value };
var params = JSON.stringify({ companyId: cpId,
startIndex: startAt,
maximumRows: tableView.get_pageSize(),
filterExpressions: filters,
dataCenterId: ddldc.options[ddldc.selectedIndex].value,
roomId: rmId,
Statuses: ddlStatuses._checkedIndices,
assetClass: ac
});
$.ajax({
url: pageUrl + '/GetSelectAssetData',
type: 'post',
contentType: 'application/json; charset=utf-8',
dataType: 'json',
data: params,
success: updateGrid,
error: OnErrorCall
});
}
function updateGrid(result) {
var tableView = $find('ctl00_MainContent_SelectAssetGrid1_gridAssetList').get_masterTableView();
tableView.set_dataSource(result.d.gridData);
tableView.dataBind();
tableView.set_virtualItemCount(result.d.count);
}
function gridAssetList_Command(sender, args) {
args.set_cancel(true);
var pageSize = sender.get_masterTableView().get_pageSize();
var currentPageIndex = sender.get_masterTableView().get_currentPageIndex();
if (args.get_commandName() == 'Filter')
currentPageIndex = 0;
getAssets(pageSize * currentPageIndex);
}
function gridAssetList_Created(sender, args) {
var fbtns = document.getElementsByClassName('rgFilter');
for (var i = 0; i < fbtns.length; i++)
fbtns[i].style.visibility = 'hidden';
var fbs = document.getElementsByClassName('rgFilterBox');
for (var i = 0; i < fbs.length; i++)
fbs[i].onkeypress = applyFilter;
}
function applyFilter(args) {
if (args.keyCode == 13)
resetGridData();
}
</script>
这在大多数情况下都有效,但如果我使用 Page.LoadControl() 加载 UserControl,它并不总是正确加载脚本。出于几个原因(可能是糟糕的原因),我想我会将脚本移动到外部文件中。
<script src="../Scripts/jquery-1.9.1.min.js" type="text/javascript"></script>
<script src="../Scripts/SelectAsset.js" type="text/javascript"></script>
.js 文件中没有额外的代码或设置,只是
function CheckThenCloseActiveToolTip(supplierID) {
var radGrid = $find('ctl00_MainContent_SelectAssetGrid1_gridAssetList_ctl00');
var selectedItems = radGrid.get_masterTableView().get_selectedItems()
if (selectedItems == null || selectedItems.length == 0) return 'You must select an asset first';
...
但现在我得到一个运行时错误,即“function gridAssetList_Command”我们未定义。该函数绑定到页面中网格的 OnCommand 事件。
当我在 Firebug 中检查页面时,它没有在脚本文件列表中列出我的 .js 文件。
我正在将我的脚本加载到 . 我没有改变它们,只是移动了它们。我错过了什么?

将功能添加到控件时,它似乎使用了不同的 ClientId。我得到的错误是动态资源中的以下内容:
Sys.Application.add_init(function() {
$create(Telerik.Web.UI.RadGrid, {"ClientID":"ctl00_MainContent_ctl03_gridAssetList","ClientSettings": ...
我将尝试将引用更改为 getElementByClass()
