Ajax Get請求將找不到JSON文件

Question

我有一個JSON文件，我試圖從中提取鍵和值，但此功能將永遠不會成功。 'datafile.json'位於完全相同的目錄中。 警報（網絡鏈接）永遠不會運行，但警報（'測試1'）工作正常。

<div class="container"> 
    <table class="table table-bordered table-striped table-hover" align="center">
        <col width="50%">
        <col>
        <col width="15%">
        <col width="25%">
        <thead>
            <tr bgcolor="#76767a" align="right">
                <th align="left">Skill</th>
                <th>Rank</th>
                <th>Level</th>
                <th>Experience</th>
            </tr>
        </thead>
    </table>
</div>

<script>
var weblink = 'datafile.json';
var data = {};
$(document).ready(function(){   
    alert('test 1');    
    $.ajax({
        type : 'GET',
        dataType : 'json',
        url : weblink,
        success: function(data){
            alert(weblink);
            $.each(datas, function(key, val){
            items.push("<tr>");
            items.push("<td id =''"+key+"''>"+val.skill+"</td>");
            items.push("<td id =''"+key+"''>"+val.rank+"</td>");
            items.push("<td id =''"+key+"''>"+val.level+"</td>");
            items.push("<td id =''"+key+"''>"+val.exp+"</td>");
            items.push("</tr>");
            });
            $("<tbody/>", {"class": "mydata", html: items.join("")}).appendTo("table");
        }
    });
});

</script>

我的datafile.json是：

您可以使用腳本標記加載json文件。 可選擇為其提供.js擴展名。 你必須將它分配給一個變量，它將被視為javascript，但也許這對你有用。

    <script type="text/javascript" language="javascript" src="datafile.json"></script>
<div class="container"> 
    <table class="table table-bordered table-striped table-hover" align="center">
        <col width="50%">
        <col>
        <col width="15%">
        <col width="25%">
        <thead>
            <tr bgcolor="#76767a" align="right">
                <th align="left">Skill</th>
                <th>Rank</th>
                <th>Level</th>
                <th>Experience</th>
            </tr>
        </thead>
    </table>
</div>

<script>
// var data is defined in the json script
$(window).load(function(){   
  $.each(data, function(skill) {
      items.push("<tr>");
      $.each(skill, function(key, val){
          items.push("<td id =''"+key+"''>"+val.skill+"</td>");
          items.push("<td id =''"+key+"''>"+val.rank+"</td>");
          items.push("<td id =''"+key+"''>"+val.level+"</td>");
          items.push("<td id =''"+key+"''>"+val.exp+"</td>");
      });
      items.push("</tr>");
  })

  $("<tbody/>", {"class": "mydata", html: items.join("")}).appendTo("table");
});

</script>
