Ajax做列表无限加载和Ajax做二级下拉选项，供大家参考，具体内容如下
//栏目Ajax做加载
public function ajaxlist(){
//echo "http://www.域名.com/index.php?a=Index&c=Index&m=ajaxlist";
//echo "<hr>";
$data = Q('sum');
$where = array();
$where['cid'] = 33;
$rongyuList = M('content')->limit($data,2)->where($where)->select();
$data['stat'] = 1;
$data = $rongyuList;
$this->ajax($data);
//也可以手动把想要的字段拼接成字符串
/*echo "[";
foreach($rongyuList as $k){
echo "{"."\""."title"."\"".":"."\"".$k['title']."\"".","."\""."description"."\"".":"."\"".$k['description']."\"".","."\""."cid"."\"".":"."\"".$k['cid']."\""."}".",";
}
echo "]";*/
}
具体页面实现：
<script type='text/javascript'>
/*ajax*/
(function(){
//发送数据
var url = "__WEB__"+"?a=Index&c=Index&m=ajaxlist";
var oSum = '';
$('a.ajaxBut').click(function(){
oSum = $('div.zizhiListContBox>a').size();
$.post(url,{sum:oSum},function(result){
console.log(result);
eval("var info="+result);
for(var key in info){
oStr = "<a href='"+"__WEB__"+"?a=Index&c=Index&m=content&mid=1&cid=33&aid="+info[key]['aid']+""+"'><h3 class='f100 f16 ts500'>"+info[key]['title']+"</h3><p>"+info[key]['description']+"</p><span class='b parb'></span></a>";
$('div.zizhiListContBox').append(oStr);
};
});
});
})();
</script>
Ajax 做二级选项：
<!-- 示例：HTML --> <dl class="pr keshi" > <dt class="pa">科室：</dt> <dd class="pa"> <select name='keshi' class='m_keshi'> <option value='0'>--请选择科室--</option> </select> <select name='zhuanjia' class='m_zhuanjia'> <option>--请选择专家--</option> </select> </dd> </dl>
示例控制器：
//示例控制器
/* Ajax请求栏目列表 */
public function ajaxlanmu(){
$lanmuList = M('category')->where('pid=142')->select();
$this->ajax($lanmuList);
}
public function ajaxzhuanjia(){
$where = array();
$data = Q('sum');
$data = $data ? $data : 143;
$where['cid'] = $data;
$zhuanjiaList = M('guahao')->where($where)->select();
$this->ajax($zhuanjiaList);
}
示例：JS
<script>
(function(){
var lanmuUrl = "__WEB__"+"?a=Index&c=Index&m=ajaxlanmu";
var zhuanjiaUrl = "__WEB__"+"?a=Index&c=Index&m=ajaxzhuanjia";
var oSum = oStr = oStr2 = oVal = oKong = info2 = oCid = '';
/* lanmu */
$.post(lanmuUrl,function(result){
eval("var info="+result);
for(var key in info){oStr += "<option value='"+info[key]['catname']+"' cid='"+info[key]['cid']+"'>"+info[key]['catname']+"</option>";};
$('dl.keshi').find('select.m_keshi').append(oStr);
});
/* zhuanjia */
$('dl.keshi').find('select.m_keshi').change(function(){
oVal = $(this).find('option:selected').val();
if(oVal == 0){
$('dl.zhuanjia').find('select.m_zhuanjia').html("<option>--请选择专家--</option>");
}else{
oCid = $(this).find('option:selected').attr('cid');
$.post(zhuanjiaUrl,{sum:oCid},function(result){
eval("info2="+result);
oStr2 = '';//注意这里要清空第一次请求的数据
for(var key2 in info2){
oStr2 += "<option value='"+info2[key2]['title']+"'>"+info2[key2]['title']+"</option>";
};
$('dl.zhuanjia').find('select.m_zhuanjia').html(oStr2);
});
};
});
})();
</script>
