Question

我尝试从文本框中获取值到变量并在同一页面中显示该值？

目标是用户将BTC钱包插入文本框，我需要将文本框中的值分配到同一页面中的变量，然后回显该值。

我试过这段代码，但是我收到了一个错误这是我的错误

在阅读了有关所有类型表单的更多内容后，我认为它有效。实际上它很容易，但我只是以错误的方式开始。现在它的工作完美这是工作代码

<h1 align="center">Welcome To Dice Game</h1>
<center><input type="text" id="wallet" />
<input type="button" onclick="getwords()" value="Enter" />
<div id="output">
</div></center>
<script language="javascript">
function getwords(){
myOutput=document.getElementById('output');
textbox = document.getElementById('wallet');
if (textbox.value != "")

myOutput.innerHTML="You entered: " + textbox.value;
else
alert("No wallet has been entered!")
}
</script>
