jquery动态实现填充下拉框
项目需要实现一个功能 当点下拉框时动态加载后台数据。这是后台数据
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {request.setCharacterEncoding("UTF-8");response.setCharacterEncoding("UTF-8");Map<String, String> product_names = DataManager.getGroup_names();StringBuffer sb = new StringBuffer();sb.append("{");Set<String> keys = product_names.keySet();for(Iterator<String> iter = keys.iterator();iter.hasNext();) {String key = iter.next();sb.append(product_names.get(key)+":");sb.append("['"+key+"'],");}sb.deleteCharAt(sb.length()-1);sb.append("}");response.getWriter().write(sb.toString());}
前台设值
$.ajax({type:"post",url:"InitData",data:"",success:function(data) {var map =eval("("+data+")");$.each(map,function(key,values){$("<option value="+values+">"+key+"</option>").appendTo("#p_name");}); }});
