搜索数据刷新页面(超级蠢的需求)

var _href = "{{ config('app.source_url') }}merchants/shareEvent/list";

function searchName(that){
    var thisurl = window.location.href;
    var inval = $(that).val();
   if(thisurl.match(/(type=0)/g)){
     window.location.href=_href+'?type=0&product_name='+inval
     }else if(thisurl.match(/(type=1)/g)){
        window.location.href=_href+'?type=1&product_name='+inval
    }else{
         window.location.href=_href+'?product_name='+inval
}
//下面不合理，会跳转页面，因为有三种状态，都会返回''
    $.ajax({
        type:'get',
        url:_href,
        dataType:"html",
        contentType:'application/json; charset=utf-8',
        data:{
            product_name:$('#searchInput').val(),
        },
        success:function(res){
            $("body").html(res);
        }
    })
}
