Javascript文本更改无法正常工作 [英] Javascript text changing not working
问题描述
您好，
我创建了一个html文件并插入了一个按钮，指的是这样下载文件：
Hello,
I created a html file and inserted a button that refers to download a file this way:
<h2><a href="file.exe" download="" style="color: #13600d">
<button width="200" height="100" >download/button></a> </h2>
我希望按钮是单击并下载启动浏览器将显示感谢您下载，所以我尝试了这个：
I wanted that when the button is clicked and the download starts the browser will show "Thank you for downloading" so I tried this:
<span id="thanks"> </span>
<script> function thankyou() {
var words = "Thanks for downloading";
document.getElementById("thanks").textContent = words;
} </script>
我点击按钮，文件下载开始但跨文本没有变化。
我尝试了什么：
我尝试找到一些解决方案，例如将textContent更改为innerHTML或innerText，但它没有'工作。
我使用谷歌浏览器作为我的浏览器。
谢谢，
Dvir
I clicked the button, the file download started but the span text didn't change.
What I have tried:
I tried finding some solutions, like change textContent to innerHTML or to innerText, but it didn't work.
I use Google Chrome as my browser.
Thanks,

推荐答案
你的代码很好，除了你需要调用你的thankyou（）函数。下面的代码显示了如何从HTML按钮标记onClick事件中调用它。我还添加了HTML 标签属性target =_ blank，因此下载将在新菜单中打开。
Your code is fine, except you need to call your thankyou() function. The code below shows how to call it from within the HTML button tag onClick event. I also added the HTML tag attribute target="_blank" so the download will open in a new menu.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<script> function thankyou() {
var words = "Thanks for downloading";
document.getElementById("thanks").textContent = words;
} </script>
</HEAD>
<BODY>
<h2><a href="file.exe" download="" target="_blank" style="color: #13600d">
<button width="200" height="100" onclick="thankyou();">download</button></a> </h2>
<span id="thanks"> </span>
</BODY>
</HTML>
将事件附加到按钮cl ick
attach the event to the button click
<a href="file.exe" download="" style="color: #13600d">
<button width="200" height="100" onclick="thankyou()">download </button>
</a>
textContent IE 9支持[ ^ ]属性+只有这样才能更好地使用 innerHTML [ ^ ] property
textContent[^] property is supported in IE 9+ only so better to use innerHTML [^] property
document.getElementById("thanks").innerText = words;
