HomeBackend DevelopmentPHP TutorialjQuery获取json后使用zy_tmpl生成下拉菜单_php技巧

第一次写关于AppCan开发的文章,有人写了关于jQuery或者原生Ajax与json的交互,那我就稍微写写我开发过程中使用jQuery获取json后使用zy_tmpl生成下拉菜单的实例吧。

PHP服务端生成json的那部分就不写那么多了,就是输入一个数组$res,然后

复制代码 代码如下:

echo $_GET['jsoncallback'] . "(" . json_encode($res) . ")";

在AppCan的模版中,先加入一个下拉菜单,我的菜单是:

<!--下拉列表开始-->
<div class=" ui-has-label">
  <label class="ui-select ">选择楼群:</label>
  <div class="ui-select">
    <div class="ui-btn ui-btn-icon-right ui-btn-corner-all ui-btn-b">
      <span class="ui-btn-inner ui-btn-corner-all" >
        <span class="ui-btn-text">楼名</span>
        <div class="ui-li-link-alt ui-btn ui-btn-corner-right ui-shadow">
        <span class="ui-icon ui-icon-arrow-d ui-icon-shadow"></span>
        </div>
      </span>
      <select name="lc" id="lc" selectedIndex="0" id="select-choice-0" onchange="zy_slectmenu(this.id)">
        数据加载中,请稍候
      </select>
    </div>
  </div>
</div>
<!--下拉列表结束-->

然后在中加入:

function getlq(){
  $.getJSON('http://localhost/json.php&#63;jsoncallback=&#63;', function(data) {
    var tmpl='<option value="${BuildingId}">${BuildingName}</option>';
    $("#lc").html("");
    $("#lc").append(zy_tmpl(tmpl,data,zy_tmpl_count(data)));
  })
}

这样在onload或者onchange、onclick时执行getlq();就能实现select的更新。

以上所述就是本文的全部内容了,希望大家能够喜欢。
