1，在没有树形控件等的情况下，后台用sql查询出树形结构数据，前台直接根据标记遍历（其实属性控件也是如此）（用js直接遍历数据）
2，还有中方式后台根据父子关系组装成list，前台用jsp标签遍历父子
<div id="div1" style="width:100%;">
</div>
$(function(){
alert("2");
appendTable();
});
function appendTable() {
alert("11");
var roleId=$("input[name='roleId']").val();
var leave=$("input[name='leave']").val();
var pId=$("input[name='pId']").val();
var dataParent = {
roleId: roleId,
leave:leave,
pId:pId
};
$.ajax({
type: "post",
url: "${pageContext.request.contextPath}/system/opmRole/Auths",
data: dataParent,
success: function (data) {
if(data!=''&&data!=null){
//alert(data);<table
var div1=$("#div1");
//var table1=$("#table1");
var table1=$("<table></table>");
var arr = eval(data);
for(j=0;j<arr.length;j++){
//alert(arr[j]);
//alert(arr[j].leave);
if(arr[j].leave=='1'){//包括两级文件夹
var row =$("<tr></tr>");
var td =$("<td></td>");
td.append($(arr[j].str));
row.append(td);
table1.append(row);
}
var row2 ;
if(arr[j].leave=='2'){//页面
row2 =$("<tr></tr>");
var td =$("<td></td>");
td.append(arr[j].str);
row2.append(td);
table1.append(row2);
}if(arr[j].leave=='3'){//按钮
var td =$("<td></td>");
td.append(arr[j].str);
table1.find("tr:last").append(td);
}
//table1.append(row2);
//var strq = JSON.stringify(table1);
alert(strq);
}
div1.html(table1);
//alert(table1);
}else{
alert("你输入的会员编号不存在！");
}
},
error:function(data){
alert("数据加载异常！");
}
});
}
//全选 选中多选框
function checkedAllBox(obj) {
if(obj.checked){
var a = document.getElementsByName(obj.value);
for (i = 0; i < a.length; i++) {
a[i].checked=true;
}
}else{
var a = document.getElementsByName(obj.value);
for (i = 0; i < a.length; i++) {
a[i].checked=false;
}
}
}
迭代的时候各个层次的数据过了方法就没有，不能共享，要实现类似共享累加：
1，返回值累加，用一个变量专门累加返回值
2,第二次回调前传入要共享的参数
