jQuery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
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(){ $.getJSON('http://localhost/json.php?jsoncallback=?', function(data) { var tmpl='<option value="${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。
