destoon教程之列表页实现自定义挑选

任何页面实现自定义挑选，不贰开内核文件，全部在模板中实现，不影响升级，不使用搜索功效。

首页在页头引入jquery.min.js 文件，默许的模板是有这个的。假如不是默许的模板，也没这个文件，请去下载个。


然后在挑选的页面引入以下JS代码：

<script>
function getQueryString(){
var result = location.search.match(new RegExp("[\?\&][^\?\&]+=[^\?\&]+","g"));
if(result == null){
return "";
}
for(var i = 0; i < result.length; i++){
result[i] = result[i].substrin(1);
}
return result;
}

function goSort(name,value){
var string_array = getQueryString();
var oldUrl = (document.URL.indexOf("index.php")==-1)?document.URL+"index.php":document.URL;
var newUrl;
if(string_array.length>0)//假如已经有挑选前提
{ var repeatField = false;
for(var i=0;i<string_array.length;i++){
if(!(string_array[i].indexOf(name)==-1)){
repeatField = true;//假如有反复挑选前提，更换前提值
newUrl = oldUrl.replac(string_array[i],name+"="+value);
}
}

//假如没有反复的挑选字段
if(repeatField == false){
newUrl = oldUrl+"&"+name+"="+value;
}

}else{//假如还没有挑选前提
newUrl = oldUrl+"?"+name+"="+value;
}

//跳转
window.location = newUrl;
}


function setSelected(name,value){
var all_li = $("#"+name).find("a");
//清除所有a标签的now类
all_li.each(function(){
$(this).removeClass("now");
});
//为选中的a增添now类
all_li.eq(value).addClass("now");
}

$(document).ready(function(){
var string_array = getQueryString();
for(var i=0;i<string_array.length;i++){
var tempArr = string_array[i].split("=");
setSelected(tempArr[0],tempArr[1]);//设定选中的挑选前提
}
});
</script>

然后在模板中引入前提语句，这下面的是挑选前提，看不懂的先学学，参照 修改。

{php $condition = "status=3";}
{php $dmode = array('',1=>" and price=0",2=>" and price>0");}
{php $dcatid = array('',1=>" and catid=10",2=>" and catid=11");}
{php $dprice = array('',1=>" and price<1001",2=>" and price>1000 and price<2000",
3=>" and price>2001 and price<3000",4=>" and price>3001 and price<5000",5=>" and and price>5001 and price<10001",6=>" and price>10000");}
{php $order = isset($order) ? intval($order) : 0;}
{php $mode = isset($mode) ? intval($mode) : 0;}
{php $dorder = array('addtime desc','price desc','hits desc');}
{php $condition.= $dmode[$mode];}
{php $condition.= $dcatid[$catid];}
{php $condition.= $dprice[$price];}
{php $condition.=" order by $dorder[$order]";}

挑选模板，仅供参照

</div>

</div>

<div class="right j-right" style="margin-left: 300px;">
<div class="sort wfs">
<div style="float:left;">
<span style="margin-left:45px; float:left; padding-top:5px; font-size:12px;">排序：</span>

<span class="sort-icons j-sort-icons" id="order">

</div>

</div>

轮回语句中&condition=后面参加上$condition
