如何将json对象的值添加到现有无序列表的span标记中（按正确顺序）？

试过这个，但它只是将对象的最后一个值添加到span标记：

$.each(case_data['stage'+id+''], function(key, value) {
    $('#stageInfo li').each(function() {
        $(this).find('span').text(value);
    });
});

对象

 {
  "baseline":{
     "duration":"1 year",
     "age":"45",
     "hba1c":"7.6",
     "fpg":"7.9",
     "bmi":"29",
     "complications":"Overweight Hypertension",
     "baseline":"Metformin"
  },
  "stage1":{
     "duration":"2 years",
     "age":"46",
     "hba1c":"8.1",
     "fpg":"8.3",
     "bmi":"29",
     "complications":"Limited Progression Hypertension",
     "baseline":"Metformin"
  },
  "stage2":{
     "duration":"5 years",
     "age":"49",
     "hba1c":"8.2",
     "fpg":"8.4",
     "bmi":"33",
     "complications":"Patient takes early retirement; daily physical activity reduced",
     "baseline":"Metformin"
  },
  "stage3":{
     "duration":"10 years",
     "age":"55",
     "hba1c":"9.3",
     "fpg":"9.8",
     "bmi":"33",
     "complications":"Diagnosed with retinopathy grade 2",
     "baseline":"Metformin"
  }
}

HTML

        <ul id="stageInfo" class="stage_info">
            <li>1 <span></span></li>
            <li>2 <span></span></li>
            <li>3 <span></span></li>
            <li>4 <span></span></li>
            <li>5 <span></span></li>
            <li>6 <span></span></li>
            <li>7 <span></span></li>
        </ul>

Answer 1

就像那样：http://jsfiddle.net/hyUzd/

var ind = 0;
$.each(case_data['stage'+id], function(key, value) {
    $('#stageInfo li').eq(ind++).find('span').text(value);
});

Answer 2

我会使用jQuery代码渲染li项目。

从UL中删除内容：

<ul id="stageInfo" class="stage_info"></ul>

并在循环中构建它：

var index = 0;
$.each(case_data['stage'+id+''], function(key, value) {
    index++;
    $("#stageInfo").append("<li>"+index+"<span>"+value+"</span></li>");
});

祝你好运

循环json对象并向现有UL元素添加值
