我正在阅读这个文本文件...我把它读成数组。

fields[0]是术语,fields[1]是定义,fields[2]是示例。

我正在尝试将我从文本文件中获取的数组传递给另一个函数,以便我可以在另一个<div>中显示定义和示例。这是我的代码:

 <html>
 <head>
     <!--<input type="file" id="fileinput" /> -->
     <script type="text/javascript">
         var xmlhttp = new XMLHttpRequest();
         xmlhttp.onreadystatechange = function allText()
         {
             if (xmlhttp.status == 200 && xmlhttp.readyState == 4)
             {
                 var inputText = xmlhttp.responseText;  // the whole text file being stored in a variable
                 var lines = inputText.split('\n');  // splitting the whole file into manageable rows using \n
                 var allMainText = "";  // declaring a variable for use later
                 for (var i = 0; i < lines.length; i++) // creating a for loop
                 {
                     var fields = lines[i].split('||');  // this is where the separation between tag, definition and example happens
                     // fields 0 is the tag itself
                     // fields 1 is the definition
                     // fields 2 is the example
                     var oneLine = '<a href = "#' + fields[0]
                                 + ' "   onclick="testFunction();"> '
                                 + '&lt;' 
                                 + fields[0]
                                 + '&gt;'
                                 + ' </a> ||';
                     allMainText += oneLine;  // += means that things can be added as the loop executes
                 }
                 document.getElementById("menu").innerHTML = allMainText;  // allMainText is displayed in the "main" div
             }
         }

         function testFunction (fields, oneLine)
         {
             var defandExample = fields[1] + '<br/>' + fields[2]; 
             document.getElementById("defandexample").innerHTML = defandExample;
         }

         xmlhttp.open("GET", "everythingtext.txt", true);  // getting the actual .txt file to be used
         xmlhttp.send();
     </script>
     <link rel="stylesheet" type="text/css" href="css/everythinghtmldynamize.css">
     <link href="https://fonts.googleapis.com/css?family=Abril+Fatface|Raleway" rel="stylesheet">

<body>
    <div id="menu"> yo </div>
    <div id="defandexample"></div>   
</body>
</html>

制作变量&#34;字段&#34;和&#34; oneLine&#34;全局范围通过在声明&#34; xmlhttp&#34;之后立即声明它们。变量
