我正在使用jqgrid inline edit我有一个方案来调用"cancel edit"按钮事件并发送消息＆＃34;您确定要取消吗？＆＃34 ;
//代码：
//卸载网格。
$('#CommentsData').jqGrid('GridUnload');
//Comments grid start.
$("#CommentsData").jqGrid({
datastr: tableSrc,
hoverrows: false,
datatype: "jsonstring",
jsonReader: {
id: 'CommentId',
repeatitems: false
},
height: 'auto',
width: 'auto',
hidegrid: false,
gridview: true,
sortorder: 'desc',
sortname: 'DateTime',
pager: '#CommentsPager',
rowList: [], // disable page size dropdown
pgbuttons: false, // disable page control like next, back button
pgtext: null, // disable pager text like 'Page 0 of 10'
viewrecords: false, // disable current view record text like 'View 1-10 of 100'
caption: "Comments",
colNames: ['DateTime', 'UserName', 'Comments'],
colModel: [
{
name: 'DateTime', index: 'DateTime', width: 120, formatter: "date", sorttype: "date",
formatoptions: { srcformat: "ISO8601Long", newformat: "m/d/Y h:i A" }
},
{ name: 'UserName', index: 'UserName' },
{ name: 'CommentText', index: 'CommentText', editable: true }],
//Events to add and edit comments.
serializeRowData: function (postdata) {
var filterResult;
var jsonResult;
if (tableSrc == "")
jsonResult = $.parseJSON(commentDetails);
else
//Parse values bind to the comments.
jsonResult = $.parseJSON(tableSrc);
var newResult = new Object();
//Check if operation is edit.
if (postdata.oper == "edit") {
//Filter the edited comments from main source.
newResult = Enumerable.From(jsonResult).Where(function (s) { return s.CommentId = postdata.id }).First();
newResult.CommentText = postdata.CommentText;
}
else {
filterResult = Enumerable.From(jsonResult).First();
newResult.CommentText = postdata.CommentText;
newResult.TransactionId = filterResult.TransactionId;
newResult.TaskId = filterResult.TaskId;
}
filterResult = JSON.stringify(newResult);
$.ajax({
url: '@Url.Action("UpdateComments", "Home")',
datatype: 'json',
data: { 'resultData': filterResult, 'action': postdata.oper },
type: 'POST',
success: OnCompleteComments,
error: function (xhr, status, error) {
if (xhr.statusText == "Session TimeOut/UnAuthorized") {
alert(xhr.statusText);
window.location.href = '@Url.Action("LogOut", "Account")';
}
else
alert(xhr.responseText);
}
});
//After update Load the grid.
function OnCompleteComments(result) {
selectTaskComment = false;
$('#dialog').dialog("close");
myfilter = $("#TransactionsGrid").jqGrid("getGridParam", "postData").filters;
rowList = $('.ui-pg-selbox').val();
Loadgrid($("#TransactionsGrid").getGridParam('page'));
}
},
onSelectRow: function (id) {
selectTaskComment = true;
var thisId = $.jgrid.jqID(this.id);
$("#" + thisId + "_iledit").removeClass('ui-state-disabled');
$("#del_" + thisId).removeClass('ui-state-disabled');
var selectValues = jQuery('#CommentsData').jqGrid('getRowData', id);
thisId = $.jgrid.jqID(this.id);
if (selectValues.UserName == '@ViewBag.UserName' || '@ViewBag.IsAdmin' == 'True') {
$("#" + thisId + "_iledit").removeClass('ui-state-disabled');
$("#del_" + thisId).removeClass('ui-state-disabled');
}
else {
$("#" + thisId + "_iledit").addClass('ui-state-disabled');
$("#del_" + thisId).addClass('ui-state-disabled');
}
}
});
jQuery("#CommentsData").jqGrid('navGrid', '#CommentsPager', { edit: false, add: false, del: true, search: false, refresh: false }, {}, {},
{
//Delete event for comments
url: '@Url.Action("UpdateComments", "Home")',
serializeDelData: function (postData) {
return {
resultData: JSON.stringify(postData.id),
action: JSON.stringify(postData.oper),
}
},
errorTextFormat: function (xhr) {
if (xhr.statusText == "Session TimeOut/UnAuthorized") {
window.location.href = '@Url.Action("LogOut", "Account")';
} else {
return xhr.responseText;
}
},
beforeSubmit: function () {
myfilter = $("#TransactionsGrid").jqGrid("getGridParam", "postData").filters;
return [true, '', ''];
},
afterSubmit: function (response, postdata) {
selectTaskComment = false;
Loadgrid($("#TransactionsGrid").getGridParam('page'));
return [true, '', ''];
}
});
$('#CommentsData').jqGrid('inlineNav', '#CommentsPager', { edit: true, add: true, save: true, del: false, cancel: true });
$("#CommentsData_iledit").addClass('ui-state-disabled');
$("#del_CommentsData").addClass('ui-state-disabled');
在哪种情况下我必须编写代码并抛出警告消息？
如果可能，还需要知道上述代码是否可以优化。因为删除事件是在比较编辑和添加的单独位置编写的。如果这是正确的方法，我有点困惑。
答案 0 :(得分：2)
调用＆＃34;取消编辑＆＃34;的最简单方法按钮将执行代码
$("#CommentsData_ilcancel").click(); // trigger click event on Cancel button
其中CommentsData是网格的ID。
