json数据格式：一个多层json，对应的遍历取内部的值。
{
"code": 0,
"message": "成功",
"data": [
{
"id": "9",
"name": "工具",
"O2OSmallCategroy": [
{
"id": "2030",
"name": "锤/锉/锯/刀/尺",
"SmallIndustry": [
{
"id": "44182",
"name": "综合套装"
},
{
"id": "44184",
"name": "电讯工具套装"
}]
}
]
}
]
}
代码是通过ajax返回json数据后的内部jquery拼接。
var strData = ‘‘; var data = json.data; $.each(data, function (index, item) { strData += ‘<li class=\"ztree_one\"><div><span class=\"root_colse root_open\"></span><a href=\"javascript:;\">‘ + item["name"] + ‘</a></div>‘; if (item["O2OSmallCategroy"].length != 0) { strData += ‘<ul>‘; $.each(item["O2OSmallCategroy"], function (i, i_item) { strData += ‘<li class=\"ztree_two\"><div><span class=\"root_colse root_open\"></span><a href=\"javascript:;\">‘ + i_item["name"] + ‘<i class=\"tree_del\" data-txt=\"2_‘ + i_item["id"] + ‘\"></i></a></div>‘; $.each(i_item["SmallIndustry"], function (j, j_item) { strData += ‘<ul><li><span class=\"tree_docu\"></span><a href=\"javascript:;\">‘ + j_item["name"] + ‘<i class=\"tree_del\" data-txt=\"3_‘ + j_item["id"] + ‘\"></i></a></li></ul>‘; }); strData += ‘</li>‘; }); strData += ‘</ul>‘; } });
