Question

我正在使用Laravel（这只是因为我需要刷新内容部分，所以我只需刷新页面的内容部分而不刷新页面。

我尝试使用jQuery删除div然后重新渲染视图，但它仍然无法正常工作。

主要问题是我有jQuery脚本，它包含在带有刀片格式的If / Then / Else中，但是我需要在不重新加载整个页面的情况下进行更改（它适用于移动设置，并且重新设置） - 在网络上渲染页面更容易，然后完全重新加载，它看起来也更好。

以下是相关代码：

  @if(Auth::check())
@if(Auth::user()->isRider() || Auth::user()->isDriver())
  <script>
    var watchid;
    var csrf_token = $('meta[name="csrf-token"]').attr('content');
    //User is already a rider/driver
    if (navigator.geolocation) {
        watchid = navigator.geolocation.watchPosition(setPos, fail, {
          enableHighAccuracy: true,
          maximumAge: 3600000,
          timeout: 20000
        });
    } else {
        alert("Geolocation is not supported by this browser.");
    }


    function setPos(pos) {
      var coords = [pos.coords.latitude, pos.coords.longitude];
      sendData('/updatePosition',
      {'latitude': coords[0], 'longitude': coords[1], '_token': csrf_token},
      function(msg) {
        //Success function
      },
      function(msg) {
        //Error function
      });
      $('#map').removeMarker('userLoc');
      $('#map').addMarker({
        coords: [coords[0], coords[1]], // GPS coords
        id: 'userLoc',
      })
      @if(Auth::user()->isDriver())
        var geocoder  = new google.maps.Geocoder();
        var address;
        var latlng = {lat: coords[0], lng: coords[1]};

          if(status == 'OK') {
            address = results[1].formatted_address;        // if address found, pass to processing function

它有点像超级类似的克隆，但是当我刷新它时我需要刷新jQuery，所以我得到了不同的脚本。

是否有其他方法可以刷新页面的内容部分而无需重新加载？或者我该怎么办？

也许只是重新创建视图是一样的？

将jquery的脚本放入Head中，并在头部添加该脚本后调用js。

的这个函数

<script type="text/javascript">
function LoadMyJs(scriptName) {
var docHeadObj = document.getElementsByTagName("head")[0];
var dynamicScript = document.createElement("script");
dynamicScript.type = "text/javascript";
dynamicScript.src = scriptName;
docHeadObj.appendChild(newScript);
}
</script>

刷新Div而不刷新页面
