Question

我正在尝试创建一个网页，其中用户在文本字段中键入一些文本，此文本如下所示。我设法通过在每次单击“提交”按钮时将此文本添加到数组中来显示用户键入的文本。每当有人加载网页时，无论是谁输入评论，我都希望用户在显示的“评论”中显示。所以它有点像留言簿。到目前为止，我尝试做的是将数组保存在外部文件中，然后在页面重新加载时加载此文件。问题是我在stackoverflow和google中搜索时找不到办法。您对我如何做到这一点有什么建议吗？

HTML：

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <link href="css/reset.css" type="text/css" rel="stylesheet">
    <link href="css/style1.css" type="text/css" rel="stylesheet">
    <title>Speak your mind</title>
</head>
<body>
    <div id="header"><h1>Speak Your Mind</h1></div>
    <div id ="description"><h2>Share with the world whatever is in your mind right now!        </h2></div>
    <div id="writeText"><textarea rows="4" cols="50" id="writeThought"></textarea></div>
    <div id="submitThoughtContainer"><button id="submitYourThought">Submit Your Thought! </button></div>
    <div id="thoughtsContainer"></div>
    <script src="js/script.js"></script>
</body>    
</html>

使用Javascript：

var thoughts = [];

window.addEventListener('load', function() {
var writeThought = document.getElementById('writeThought');
var recentThought;
var thoughtsContainer = document.getElementById('thoughtsContainer');
var submitYourThought = document.getElementById('submitYourThought');
var thoughtsTemporal = "";

submitYourThought.addEventListener('click', function() {
    recentThought = writeThought.value;
    thoughts.splice(0, 0, recentThought);
    writeThought.value = "";
    thoughtsTemporal = "";
    for(var i = 0; i < thoughts.length; i++) {
        thoughtsTemporal += '<div class="thoughts">'+ thoughts[i] +'</div>';
        thoughtsContainer.innerHTML = "" + thoughtsTemporal;
        }
    });                      
});

如何将javascript数组保存为外部文件，然后加载它
