Question

我可以从服务返回任何JSON。基于JSON，我需要动态创建SelectBoxes并填入其中的值。

EG -

 JSON = {
    "Level": [{
        "Product": [{
            "ID": "ID1",
                "Brand": "Brand2",
                "Type": "Type3",
                "Line": "Line4",
                "Family": "Family5"
        }],
            "Location": [{
            "City": "City1",
                "State": "State2",
                "Region": "Region3",
                "Country": "Country4"
        }],
            "Time": [{
            "Day": "Day1",
                "Week": "Week2",
                "Month": "Month3",
                "Quarter": "Quarter4",
                "Year": "Year5"
        }]

    }]
}

在这种情况下，将创建3个主选择框，其下方有子选择框。喜欢 - OneMain SelectBox - 时间，低于时间5个选择框，第二个SelectBox - 位置，在另外4个选择框之下，依此类推。

如何使其动态达到这样的水平是完全无能为力的。

Answer 1

试试这个，

var level=JSON['Level'][0];
for(var pr in level){
    var $select =$('<select/>');
    $select.append('<option>'+pr+'</option>');
    key=level[pr][0];
    for(k in key){
         $select.append('<option>'+key[k]+'</option>'); 
    }
    $select.appendTo('body');
}

嗨，我认为这就是你想要的example，我使用Jquery

var  JSONS = {
    "Level": [{
      "Product": [{
            "ID": "ID1",
                "Brand": "Brand2",
                "Type": "Type3",
                "Line": "Line4",
                "Family": "Family5"
        }],
            "Location": [{
            "City": "City1",
                "State": "State2",
                "Region": "Region3",
                "Country": "Country4"
        }],
            "Time": [{
            "Day": "Day1",
                "Week": "Week2",
                "Month": "Month3",
                "Quarter": "Quarter4",
                "Year": "Year5"
        }]

    }]
} 

$(document).ready(function(){
    $.each(JSONS.Level[0],function(key,val){
       var currentSection = val[0];

        var selectEle=$('<select id="'+key+'"></select>');
        $.each(currentSection,function(k,va){
          var op =  "<option>"+va+"</option>";
            selectEle.append(op);

        });

        $('#selectWrap').append(selectEle);        
    });



});

使用jquery基于JSON创建动态SelectBox
