四、jquery代码 tree.js

var treeData = {};

function getTree(obj, tree) {
treeData = tree;
var data = tree.data;
var treeContentStart = "";
var treeContentEnd = "";

if(data.length > 0) {
treeContentStart += '<ul class="nav nav-pills tree-ul-first" role="tablist">';
$.each(data, function(i, n) {
var menuLeftIcon = n.menuLeftIcon ? n.menuLeftIcon : 'glyphicon glyphicon-paperclip';
if(n.menuChildData && n.menuChildData.length > 0) {
treeContentStart += '<li role="presentation">' +
'<a href="javascript:void(0)" data-url="' + n.menuUrl + '" onclick="openChildNotes(this)">' +
'<span class="tree-span-left ' + menuLeftIcon + '"></span>' + n.menuName + '<span class="' + tree.clickIconBefore + ' tree-span-right"></span></a>';
treeContentStart += fillTreeData(n.menuChildData);
} else {

'<a href="javascript:void(0)" data-url="' + n.menuUrl + '">' +
'<span class="tree-span-left ' + menuLeftIcon + '"></span>' + n.menuName + '</a>';
}
treeContentStart += '<li>';
});
treeContentEnd += "</ul>";
}
obj.html(treeContentStart + treeContentEnd);
}

function fillTreeData(data) {
var treeContentStart = "";
var treeContentEnd = "";
if(data.length > 0) {
treeContentStart += '<ul class="nav nav-pills tree-ul-childs">';
$.each(data, function(i, n) {
var menuLeftIcon = n.menuLeftIcon ? n.menuLeftIcon : 'glyphicon glyphicon-paperclip';
if(n.menuChildData && n.menuChildData.length > 0) {
treeContentStart += '<li>' +
'<a href="javascript:void(0)" data-url="' + n.menuUrl + '" onclick="openChildNotes(this)"><span class="tree-span-left ' + menuLeftIcon + '"></span>' + n.menuName + '<span class="' + treeData.clickIconBefore + ' tree-span-right"></span></a>';
treeContentStart += fillTreeData(n.menuChildData);
} else {
treeContentStart += '<li>' +
'<a href="javascript:void(0)" data-url="' + n.menuUrl + '"><span class="tree-span-left ' + menuLeftIcon + '"></span>' + n.menuName + '</a>';
}
treeContentStart += '<li>';
});
treeContentEnd += "</ul>";
}
return treeContentStart + treeContentEnd;
}

function openChildNotes(obj) {
var o = $(obj);
var showState = o.next().css("display");
var leftOff = o.css("padding-left");
var paddingLeft = leftOff.substring(0, leftOff.length - 2);
if(showState == "block") {
showState = "none";
o.find("span").last().removeClass(treeData.clickIconAfter).addClass(treeData.clickIconBefore);
o.next().find("li").find("a").css("padding-left", (parseInt(paddingLeft) - 20) + 'px');
$("ul", o.next("ul")).css("display", showState);
$("li a span.tree-span-right", o.next("ul")).removeClass(treeData.clickIconAfter).addClass(treeData.clickIconBefore);
} else {
showState = "block";
o.find("span").last().removeClass(treeData.clickIconBefore).addClass(treeData.clickIconAfter);
o.next().find("li").find("a").css("padding-left", (parseInt(paddingLeft) + 20) + 'px');
}
o.next("ul").css("display", showState);
}
