我在一个js文件中编写了带有deferd和promise的函数。之后,我在另一个HTML文件(在其中创建菜单)中调用该函数,此页面将用作Web部件。所以我想在菜单生成后运行该函数,该怎么做。
Ph.DAL = function() {
this.getRequest = function(listName, select, filter, orderby, top, _async) {
var dfd = $.Deferred()
var request = baseRequest
request.type = 'GET'
request.async = _async
request.url =
siteAbsoluteUrl +
"/_api/web/lists/getbytitle('" +
listName +
"')/items?" +
(this.isNullOrEmpty(select) ? '' : '$select=' + select) +
'&' +
(this.isNullOrEmpty(filter) ? '' : '$filter=' + filter) +
'&' +
(this.isNullOrEmpty(orderby) ? '' : '$orderby=' + orderby) +
'&' +
(this.isNullOrEmpty(top) ? '' : '$top=' + top)
request.headers = { ACCEPT: 'application/json;odata=verbose' }
dfd = $.ajax(request)
return dfd.promise()
}
我要从另一个html页面调用以生成动态菜单
$(document).ready(function() {
var utility = new Ph.DAL()
var menuHTML = ''
utility
.getRequest(
'Navigation',
'Id,Title,Icon,URL,Target,ParentId,OrderBy',
"Active eq 'Yes'",
'',
'',
true
)
.done(function(data) {
if (data && data.d && data.d.results && data.d.results.length > 0) {
createMenu(data.d.results, null)
}
$('#respMenu').html(menuHTML)
$('#respMenu').aceResponsiveMenu({
resizeWidth: '768', // Set the same in Media query
animationSpeed: 'fast', //slow, medium, fast
accoridonExpAll: false, //Expands all the accordion menu on click
})
})
function createMenu(jSON, parentId) {
var _menu
_menu = Enumerable.from(jSON)
.where(function(value) {
return value.ParentId == parentId
})
.orderBy(function(value) {
return value.OrderBy
})
.toArray()
if (_menu.length > 0) {
_menu.map(function(item, i) {
menuHTML +=
'<li class="' +
(item.URL.toLowerCase() == utility.pageName.toLowerCase() ? 'active' : '') +
'"><a href="' +
item.URL +
'">'
menuHTML +=
'<i class="' +
item.Icon +
'"></i><span class="title">' +
item.Title +
'</span></a>'
var subMenu = Enumerable.from(jSON)
.where(function(value) {
return value.ParentId == item.Id
})
.orderBy(function(value) {
return value.OrderBy
})
.toArray()
if (subMenu.length > 0) {
createSubMenu(jSON, subMenu)
}
menuHTML += '</li>'
})
}
}
function createSubMenu(mainData, data) {
menuHTML += '<ul>'
data.map(function(item, i) {
menuHTML += '<li><a href="' + item.URL + '">' + item.Title + '</a>'
var subMenu = Enumerable.from(mainData)
.where(function(value) {
return value.ParentId == item.Id
})
.orderBy(function(value) {
return value.OrderBy
})
.toArray()
if (subMenu.length > 0) {
createSubMenu(mainData, subMenu)
}
})
menuHTML += '</li></ul>'
}
})
现在我正在尝试循环li并想在特定的类上添加活动类,但是生成了菜单,并且函数调用更早了,所以它不起作用。我该怎么办。
在创建菜单后运行此功能
$.menuActive = function (menuItem) {
$('#respMenu li').each(function() {
if ($(this).text() == menuItem) {
$(this).addClass('active')
return false
}
})
}

您应该尝试使用MutationObserver API
var mutationObserver = new MutationObserver(function(mutations) {
mutations.forEach(function(mutation) {
// Do something here
});
});
mutationObserver.observe(myRefElement, {attributes: true})

//You can use custom events
//Do this after $('#respMenu').html(menuHTML)
$( "#respMenu" ).trigger( "list_ready" );
//In another file
$( "#respMenu" ).on( "list_ready", function () {
//Do ur stuff here
});
