我創(chuàng)建了一個在 HTMLdiv元素中創(chuàng)建內(nèi)部元素的腳本。它工作正常，但我認為我使用字符串的方式在 JavaScript 中不是最合適的。HTML<body> <div class="chart-container"> <div class="chartlyrics">...</div><div class="chartlyrics box" id="powered_by"></div> </div> </body>“ ... ”所在的位置是我創(chuàng)建元素的位置。Javascriptdocument.getElementsByClassName('chartlyrics')[0].innerHTML = '<img src="img/103-logo.jpg" class="" /><br />Powered by 'HTML 結(jié)果：<body> <div class="chart-container"> <div class="chartlyrics"><img src="img/103-logo.jpg" class="" /><br />Powered by </div><div class="chartlyrics box" id="powered_by"></div> </div> </body>在 JavaScript 中創(chuàng)建元素時如何不使用字符串來執(zhí)行此操作？我試過了，但它給了我一個語法錯誤：document.getElementsByClassName('chartlyrics')[0].innerHTML = '' var img = document.getElementsByClassName('chartlyrics') .appendChild(document.createElement("img")); img.src = "img/103-logo.jpg"img.class = ""img.textContent = 'Powered by ' console.log(document.getElementsByClassName('chartlyrics')[0].innerHTML);結(jié)果：document.getElementsByClassName (...). appendChild is not a function
從 JavaScript 正確地將 img src 添加到 html
