如何将数组转换为另一个函数，以便将其显示到另一个div中

Question

I have this text file I am reading... I read it into an array. 我有这个正在阅读的文本文件...我把它读成数组。

fields[0] is the term, fields[1] is the definition and fields[2] is the example. fields[0]是术语， fields[1]是定义， fields[2]是示例。

I am trying to pass the array I get from the text file into another function so I can display the definition and example in another <div> . 我试图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>显示定义和示例。 Here is my code: 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>

通过声明“xmlhttp”变量后立即声明变量“fields”和“oneLine”全局范围。
