织梦dedecms中tag标签地址栏小问题解决

<script type="text/javascript"> 
var url=window.location.href;


//提取?问后的内容
function getCaption(obj){
    var index=obj.lastIndexOf("\?");
    obj=obj.substring(index+1,obj.length);
    return obj;
}

//去掉数组中的空值
Array.prototype.notempty = function() {
    var arr = [];
    this.map(function(val, index) {
        //过滤规则为，不为空串、不为null、不为undefined，也可自行修改
        if (val !== "" && val != undefined) {
            arr.push(val);
        }
    });
    return arr;
}

var str=getCaption(url);
var arr=str.split("/");
var cen = arr.notempty();

//处理输入的地址不带页数的问题
if(cen[1]==undefined)
{
	var urls = url.charAt(url.length-1);
	if(urls =="/")
	{
		window.location.href=url+"1/";
		}else{
		window.location.href=url+"/1/";
			}
	}


</script>
