I'm trying to create a nested UL from JSON. I am able to loop through and grab the data from the object, but I am having trouble building the nested UL. I figure the '.append' method is placed in the wrong spot. The resulting LIs are all grouped together. How do I create a loop (or another way is fine too) that will build the UL with the submenu LIs properly nested? I've tried using other similar posts to solve my issue, but I can't seem to make it make sense with my data and code. A little braindead from this - I've tried a few methods to create this dynamic list and so far none has been successful. Any help would be appreciated :)
我正在尝试从JSON创建一个嵌套的UL。我能够循环并从对象中获取数据，但是我在构建嵌套的UL时遇到了麻烦。我图”。append的方法被放置在错误的位置。产生的LIs都被分组在一起。我如何创建一个循环(或者另一种方法也是好的)，它将使用正确嵌套的子菜单构建UL ?我尝试过使用其他类似的文章来解决我的问题，但是我的数据和代码似乎没有意义。我已经尝试了一些方法来创建这个动态列表，到目前为止还没有一个成功。如有任何帮助，我们将不胜感激。

I build the loop to access all of the nested menu data:
我构建循环来访问所有嵌套的菜单数据:
var mainMenu = $("#test ul.mainMenu");
var subMenuL1 = $("#test ul.mainMenu ul.submenuLevel1");
var subMenuL2 = $("#test ul.mainMenu ul.submenuLevel1 ul.submenuLevel2");
var i, j, k, navItem, navItemLevel1, navItemLevel2;
for(var i = 0; i < menu.length; i++){
var navItem = menu[i];
mainMenu.append('<li class="main"><a href="' + navItem.url + '">' + navItem.title +' </a></li>');
for(var j = 0; j < menu[i].menu.length; j++){
var navItemLevel1 = navItem.menu[j];
subMenuL1.append('<li class="level1"><a href="' + navItemLevel1.url + '">' + navItemLevel1.title +' </a></li>');
for(var k = 0; k < menu[i].menu[j].menu.length; k++){
var navItemLevel2 = navItemLevel1.menu[k];
subMenuL2.append('<li class="level2"><a href="' + navItemLevel2.url + '">' + navItemLevel2.title +' </a></li>');

You can use a recursive function for appending submenus.
可以使用递归函数添加子菜单。
This is a simple solution for three sublevels or more
对于三个或更多的子级别，这是一个简单的解决方案
function appendMeu(parent, menu, level) {
for(var i = 0;i < menu.length; i ++) {
var submenu = parent.append('<li>' + menu[i].title + '</li>')
.find("li:last");
if(menu[i].menu != undefined && menu[i].menu.length > 0) {
submenu = submenu.append('<ul class="submenuLevel' + (level + 1) + '"></ul>').find("ul");
appendMeu(submenu, menu[i].menu, level + 1);
}
}
}
$(function() {
appendMeu($(".mainMenu"), menu, 0);
});

Most of what you make is dynamic so start with something like this
你做的大部分都是动态的，所以从这个开始
<div id="test">
<ul class="mainMenu">
</ul>
</div>
Then in your code use the things you just made and add to them. Something like this:
然后在您的代码中使用您刚刚制作的东西并添加到它们中。是这样的:
for(var i = 0; i < menu.length; i++){
var navItem = menu[i];
subMenuL1 = mainMenu.append('<li class="main"><a href="' + navItem.url + '">' + navItem.title +' </a></li>');
for(var j = 0; j < menu[i].menu.length; j++){
var navItemLevel1 = navItem.menu[j];
subMenuL2 = subMenuL1.append('<li class="level1"><a href="' + navItemLevel1.url + '">' + navItemLevel1.title +' </a></li>');
for(var k = 0; k < menu[i].menu[j].menu.length; k++){
var navItemLevel2 = navItemLevel1.menu[k];
subMenuL2.append('<li class="level2"><a href="' + navItemLevel2.url + '">' + navItemLevel2.title +' </a></li>');
}
}
};

Here's how to do this with the jQuery template plugin I mentioned
下面是我提到的jQuery模板插件。
This would be in your script tag:
这将在您的脚本标记中:
$(function () {
$('#t_menu').tmpl(menu).appendTo('#test');
});
And this in your html :
在你的html中:
<div id="test"> </div>
<script id="t_menu" type="text/html">
<ul class="mainMenu">
{{each menu}}
<li class="main">
<a href="${url}">${title}</a>
<ul class="submenuLevel1">
{{each menu}}
<li class="level1">
<a href="${url}">${title}</a>
<ul class="submenuLevel2">
