這是我輸入文本的地方：單擊“計數(shù)”按鈕后，它將轉(zhuǎn)到此頁面：我的文字和字?jǐn)?shù)被顯示出來了。但是，我如何使用普通的JavaScript獲取此文本的單詞密度，并在此頁面上實(shí)際顯示它？這是我的網(wǎng)頁：<!DOCTYPE html><html> <head> <title>Word Counter</title> </head> <body> <div id="input-page"> <h1>Word Counter</h1> <form action=""> <textarea id="text" type="text" rows="22" cols="60"></textarea> <br /> </form> <button onclick="displayText()">COUNT</button> </div> <div id="count-page" style="display: none;"> <h1>Your Text:</h1> <p id="display-text"></p> <div id="word-count"></div> <div id="word-density"> <h1>Word Density:</h1> </div> </div> </body> <script src="app.js"></script></html>腳本：const displayText = () => { const inputPage = document.getElementById("input-page"); const countPage = document.getElementById("count-page"); const text = document.getElementById("text"); const textValue = text.value; if (text.value !== "") { // normal flow will continue if the text-area is not empty inputPage.style.display = "none"; document.getElementById("display-text").innerText = textValue; countPage.style.display = "block"; } else { // if the text-area is empty, it will issue a warning. alert("Please enter some text first.") } const countWords = (str) => { return str.split(" ").length; }; const wordCount = (countWords(textValue)); const renderWordCount = () => { const wordCountDiv = document.getElementById("word-count"); wordCountDiv.innerHTML = "<h1> Words Counted: " + wordCount + "</h1>"; }; renderWordCount();};
