获取输入值并显示在另一个div中 [英] Take input value and display in another div
问题描述
我不知道为什么以下不起作用。我从W3school的示例此处。
基本上我想从输入文本中取值，当它改变并修改另一个div以包含该值时。我只想让div显示新的价值，但我确实希望它每次都改变它，所以我认为onchange是要走的路。
<！DOCTYPE html>
< html>
< head>
< script>
函数myFunction（）
{
var div = document.getElementById（'divID'）;
div.innerHTML = div.innerHTML + x.value;
}
< / script>
< / head>
< body>
输入您的姓名：< input type =textid =fnameonchange =myFunction（）>
当您离开输入栏时，会触发一个功能，将输入文本转换为大写。< / p>
< div id =divID>< / div>
< / body>
< / html>
预先感谢此次的所有帮助。
你有两个问题，第一个是x未定义。
秒，你应该使用另一个触发器，以便每次都发生这种情况。
尝试一下：
function myFunction（）
{
var input = document.getElementById（'fname'）
var div = document.getElementById（'divID' ）;
div.innerHTML = div.innerHTML + input.value;
}
并将您的html更改为：
< input type =textid =fnameonkeypress =myFunction（）>
I cant for the life of me figure out why the following is not working. I took if from the W3school example here.
Basically I want to take the value from the input text when it changes and modify another div to include the value. I only want the div to show the new value, but I do want it to change it each time so I figured the onchange was the way to go.
<!DOCTYPE html>
<html>
<head>
<script>
function myFunction()
{
var div = document.getElementById('divID');
div.innerHTML = div.innerHTML + x.value;
}
</script>
</head>
<body>
Enter your name: <input type="text" id="fname" onchange="myFunction()">
<p>When you leave the input field, a function is triggered which transforms the input text to upper case.</p>
<div id="divID"></div>
</body>
</html>
Thanks in advance for all the help on this one.
You have 2 problems, first is that x is undefined. second you should use another trigger for this for this to happen each time.
try this out:
function myFunction()
{
var input = document.getElementById('fname')
var div = document.getElementById('divID');
div.innerHTML = div.innerHTML + input.value;
}
and change your html to:
<input type="text" id="fname" onkeypress="myFunction()">
