Question

我是使用ajax的新手。我有一个ajax程序，当一个人在搜索栏中查找用户时，它会搜索用户。它在每个键上执行的操作是使用ajax从数据库中提取数据以供推荐以帮助用户选择。但问题是它对大多数页面都有效，除了编辑和显示特定数据的页面。

这里是ajax

   function suser(str){

        var xhttp;
        if(str.length==0)
        { document.getElementById("srtd").innerHTML = "" 
            document.getElementById("srtd").style.border="0px";
            return;}
        else{
        if (window.XMLHttpRequest) {
        xhttp = new XMLHttpRequest();
        } else {
        // code for IE6, IE5
        xhttp = new ActiveXObject("Microsoft.XMLHTTP");
            }
            xhttp.onreadystatechange = function() {
        if (xhttp.readyState == 4 && xhttp.status == 200) {
            var res=xhttp.responseText;
            var i=JSON.parse(res);
            var j=i.length;
            document.getElementById("srtd").innerHTML = "";
          var  d=document.getElementById("srtd");
        var u=document.createElement("ul");
        u.style="list-style-type:none";

            d.appendChild(u);
            for(var k=0; k<j ; k++){
         var    li=document.createElement("li");

         u.appendChild(li);
            li.innerHTML="<a href='livsearres/"+ i[k].id +"' class='btn' >"+ i[k].name +" "+i[k].fname+" "+i[k].gname+"</a>";

            }
            //document.getElementById("srtd").innerHTML="<a href='showuser/"+ i[0].id +"' class='btn mybtn-n' >"+ i[0].name +" "+i[0].fname+"</a>";


        }
      }
      xhttp.open("GET", "lusrser/"+str, true);
      xhttp.send();}
    }

这是我的控制器，它返回用户的ajax

public function livesearch($str)
{

    $users=User::where('name', 'LIKE', $str.'%')->orWhere('userid', 'LIKE', $str.'%')->get();
     $searchs = explode(" ", $str);

    if (count($searchs) == 1)
    {
    $users=User::where('name', 'LIKE', $str.'%')->orWhere('userid', 'LIKE', $str.'%')->get();
          return $users;
      }
       elseif (count($searchs) == 2)
    {
    $users=User::where('name', 'LIKE', $searchs[0].'%')->where('fname', 'LIKE', $searchs[1].'%')->get();
          return $users;
      }
       elseif (count($searchs) == 3)
    {
    $users=User::where('name', 'LIKE', $searchs[0].'%')->where('fname', 'LIKE', $searchs[1].'%')->where('gname', 'LIKE', $searchs[2].'%')->get();
       return $users;
      }
      else 
    {
        $users="[]";
   return  $users;
      }

}

在每个页面上都有类似的搜索输入

<input   onkeyup="suser(this.value)" type="search" name="search" class="form-control"  placeholder="Search" >

网址

route::get('/indexuser','UserController@index');
route::get('/createuser','UserController@create');
route::post('/createuser','UserController@store');
route::get('/edituser/{id}','UserController@edit');
route::post('/edituser','UserController@update');
route::get('/showuser/{id}','UserController@show');

因为仅在showuser和edituser上工作时我认为它与编辑或显示的id的附加数据有关，任何正文都可以帮助我解决它。

错误消息是

如果您使用的是刀片文件，则可以使用此技巧。

像这样定义一个javascript变量。

var SiteUrl = '{{ url::to("") }}';

你可以用这样的ajax网址连接它。

xhttp.open("GET", SiteUrl+"lusrser/"+str, true);

如果您在baseURL中添加了'/'，请使用上面的

否则您可以使用xhttp.open("GET", SiteUrl+"/lusrser/"+str, true);

希望这有帮助......别的让我知道。

ajax不会为他们的网址中有id的网页工作吗？
