我试图解决在jQuery数据表中停留在当前页面上的问题。单击一行中的“编辑”链接时,将打开一个模式弹出窗口并填充控件。这需要一个将页面再次设置为第1页的回发。花了整个上午寻找解决方案,没有工作。
所以我决定用ajax填充模态;解决了我的分页问题,但不知何时没有填充模态中的控件。
这就是我的尝试:
<div class="modal fade" id="editModal" role="dialog" aria-labelledby="editLabel" aria-hidden="true">
<div class="modal-dialog fade in ui-draggable">
<div class="modal-content">
<div class="modal-header ui-draggable-handle">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title"><span id="spnEditHeader"></span></h4>
</div>
<div class="modal-body">
<div class="row">
<div class="col-sm-3">
....
</div>
<div class="col-sm-4">
<div class="form-group">
<label for="ddlArea">Area</label>
<asp:DropDownList runat="server"
ID="ddlArea"
ClientIDMode="Static"
CssClass="form-control"
DataTextField="AreaName"
DataValueField="AreaID"
AppendDataBoundItems="true">
<asp:ListItem Text="Select Area" Value="-1" />
</asp:DropDownList>
</div>
</div>
<div class="col-sm-5">
<div class="form-group">
<label for="ddlDistrict">District</label>
<asp:DropDownList runat="server"
ID="ddlDistrict"
Enabled="false"
ClientIDMode="Static"
CssClass="form-control"
DataTextField="DistrictName"
DataValueField="DistrictID"
AppendDataBoundItems="true">
<asp:ListItem Text="Select District" Value="-1" />
</asp:DropDownList>
</div>
</div>
</div>
(带编辑链接的数据表的一部分):
tblMPOO = $('#tblMPOO').DataTable({
jQueryUI: true,
data: [],
dom: 'lfrtip',
stateSave: true,
stateDuration: 60 * 10,
order: [[0, "asc"], [1, "asc"], [2, "asc"]],
"columns": [
{
"data": "MPOOID"
}, { ...
}, {
"render": function (data, type, row) {
var cellContent = '';
cellContent =
"<a href='javascript:' onclick=\"showEdit('" + row.MPOOID + "'); \">Edit</a> | " +
"<a href='javascript:' onclick=\"deleteCourse('" + row.MPOOID + "', '" + row.DistrictID + "'); \">Delete</a>";
return cellContent;
}
],
"pageLength": 15,
processing: true
});
$(document).ready(function () {
$('#editModal').modal({
keyboard: true,
backdrop: "static",
show: false
}).on('show.bs.modal', function (e) {debugger
//var mpooID = $(e.relatedTarget).data('MPOOID');
var mpooID = $('#hfMPOOID').val();
//make ajax call to populate items
populateMPOOEdit(mpooID);
});
$(".modal-dialog").draggable({
handle: ".modal-header"
});
});
function showEdit(MPOOID) {debugger
$('#hfMPOOID').val(MPOOID);
showEditModal();
}
function showEditModal() {
some other stuff here ...
$('#editModal').modal('show');
}
function populateMPOOEdit(mpooID) {
$.ajax({
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
url: '<%= ResolveUrl("services/mpoo.asmx/GetMPOOListByMPOOID") %>',
cache: false,
data: JSON.stringify({ "MPOOID": mpooID }),
}).done(function (result) {
jResult = JSON.parse(result.d);
$.each(jResult, function (val, txt) {debugger
$('#tbMPOOName').val = txt.MPOOName;
// $('#tbMgrFN').val = txt.ManagerFirstName; <--- This is wrong, corrected below
$('#tbMgrFN').val(txt.ManagerFirstName);
$('#tbMgrLN').val(txt.ManagerLastName);
$('#tbPhone').val(txt.Phone);
$('#tbEmail').val(txt.Email);
var AreaID = txt.AreaID;
var DistrictID = txt.DistrictID;
$("#ddlArea")[0].selectedIndex = 0;
$("#ddlDistrict")[0].selectedIndex = 0;
$("#ddlArea").val(AreaID);
$("#ddlArea").change(); <-- added this to force its onchange event to fire
$("#ddlDistrict").val(DistrictID); <-- This still doesn't work
});
}).fail(function (jqXHR, textStatus, errorThrown) {
var errMsg = textStatus + ' - ' + errorThrown + '... Status: ' + jqXHR.status + ", ResponseText: " + jqXHR.responseText;
});
}
另一个问题,在同一个上下文中:我使用ajax根据另一个下拉列表中的选择更改填充一个下拉列表(两个下拉都在上述模态中)。我使用第一个DDL的onchange()来填充第二个DDL。工作良好。
假设此问题已解决且控件已填充,请在js函数中设置第一个下拉值是否会触发其onchange事件?
更新
我做了一些修改问题的修改,控件值没有填充;用更新的代码标记它们。在“populateMPOOEdit()”中,我还强制触发Area下拉列表的onchange()事件。但是,在下一行,当我设置区下拉的选定值时,它不起作用(某些时间问题?)
