我在嵌套网格的 JqWidgets 上下文菜单中面临双重发布问题。该事件正在触发 n 次(其中“n”是我单击上下文菜单的时间)
除此之外,如果我将事件处理程序方法保留在上下文菜单创建之外,而不是在这种情况下事件处理程序没有被调用
场景 1(我遇到双重发布问题,无法获取选定的行列值)
//handle context menu clicks.
var teamButtonClick = function (event) {
try{
// create context menu for Task
var taskContextMenu = jQuery("#teamMenu").jqxMenu({ width: 160, height: 162, autoOpenPopup: false, mode: 'popup'});
jQuery("#<portlet:namespace />teamGrid").on('contextmenu', function () {
return false;
});
jQuery("#teamMenu").on('itemclick', function (event) {
try {
var args = event.args;
var rowindex = jQuery("#teamGrid").jqxGrid('getselectedrowindex');
if (jQuery.trim(jQuery(args).text().trim()) == "Add User") {
editrow = rowindex;
jQuery("#rowId").val(editrow);
var dataRecord = jQuery("#teamGrid").jqxGrid('getrowdata', args.rowindex);
alert(dataRecord);
}
}catch(e) {alert(e);}
});
var buttonID = event.target.id;
jQuery("#teamGrid").jqxGrid('selectrow', buttonID);
var scrollTop = jQuery(window).scrollTop();
var scrollLeft = jQuery(window).scrollLeft();
taskContextMenu.jqxMenu('open', parseInt(event.clientX) + 5 + scrollLeft, parseInt(event.clientY) + 5 + scrollTop);
return false;
}catch(e) {
alert('error in contextmenu: ' + e);
}
}
场景 2(当我保持在上下文菜单创建块之外时,我的事件处理程序没有被调用)
// event handler is not getting called in this case
jQuery("#teamMenu").on('itemclick', function (event) {
try {
var args = event.args;
var rowindex = jQuery("#teamGrid").jqxGrid('getselectedrowindex');
if (jQuery.trim(jQuery(args).text().trim()) == "Add User") {
editrow = rowindex;
jQuery("#rowId").val(editrow);
var dataRecord = jQuery("#teamGrid").jqxGrid('getrowdata', args.rowindex);
alert(dataRecord);
}
}catch(e) {alert(e);}
});
//handle context menu clicks.
var teamButtonClick = function (event) {
try{
// create context menu for Task
var taskContextMenu = jQuery("#teamMenu").jqxMenu({ width: 160, height: 162, autoOpenPopup: false, mode: 'popup'});
jQuery("#<portlet:namespace />teamGrid").on('contextmenu', function () {
return false;
});
var buttonID = event.target.id;
jQuery("#teamGrid").jqxGrid('selectrow', buttonID);
var scrollTop = jQuery(window).scrollTop();
var scrollLeft = jQuery(window).scrollLeft();
taskContextMenu.jqxMenu('open', parseInt(event.clientX) + 5 + scrollLeft, parseInt(event.clientY) + 5 + scrollTop);
return false;
}catch(e) {
alert('error in contextmenu: ' + e);
}
}
