js defines object array (combination) multi-dimensional array method

Defining an array in php is very simple, but in js it will make an error if characters are subscripted, so combine it with objects

var top_ = {
 
    'index':'首页',
    'user':'用户',
    'tree':'模块树'
} ;
var all_list = [
    {
         
         "index": [
             {'name':'网站栏目管理','url':'1.html'},
             {'name':'网站栏目管理2','url':'2.html'}
         ]
         
          
    },
    {
        "user": [
             {'name':'用户管理','url':'user.html'},
             {'name':'用户添加','url':'add.html'}
         ]
         
    },
    {
        "tree": [
             {'name':'模块树管理','url':'manager.html'},
             {'name':'模块树添加','url':'add_new.html'},
             {'name':'模块树添333加','url':'add_ne33w.html'}
         ]
         
    }
];

The above defines a module tree array. . . .

In addition, when retrieving data, it is also very easy to retrieve.

//根据顶部的下标得到左边菜单
function return_left_menu_by_index(index){
 
var left_ = '' ;
for(var i in all_list){
 
for(var j in all_list[i]){ 
if(j == index){
//默认显示的菜单
//console.dir(all_list[i][j]);
for(var k in all_list[i][index]){
//console.dir(k);
var new_onclick = 'onclick=change_right_url("'+all_list[i][index][k].url+'")' ;
left_+='<div style="width:120px; height:30px;line-height:30px;border:solid 1px; margin:3px;padding:2px;cursor:pointer" '+new_onclick+'>'+all_list[i][index][k].name+'</div>';
}
}
 
}
}
 
return left_ ;
}
