I want there to be a textbox on my screen(like the one i'm typing in now) that you can type in then click a submit button and it sends whatever you typed in the box to javascript and javascript prints it out.Here is my code This is the part that works.
<html>
<body>
<input type="text" id="userInput"=>give me input</input>
<button onclick="test()">Submit</button>
<script>
function test()
{
var userInput = document.getElementById("userInput").value;
document.write(userInput);
}
</script>
</body>
</html>
OK so that's nice, but lets say I want input from that textbox and button while I'm already in a function and don't want to restart the function?
Thanks, Jake
This question is related to
javascript
html
input
user-input
I tried to send/add input tag's values into JavaScript variable which worked well for me, here is the code:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function changef()
{
var ctext=document.getElementById("c").value;
document.writeln(ctext);
}
</script>
</head>
<body>
<input type="text" id="c" onchange="changef"();>
<button type="button" onclick="changef()">click</button>
</body>
</html>
Late reading this, but.. The way I read your question, you only need to change two lines of code:
Accept user input, function writes back on screen.
<input type="text" id="userInput"=> give me input</input>
<button onclick="test()">Submit</button>
<!-- add this line for function to write into -->
<p id="demo"></p>
<script type="text/javascript">
function test(){
var userInput = document.getElementById("userInput").value;
document.getElementById("demo").innerHTML = userInput;
}
</script>
This is bad style, but I'll assume you have a good reason for doing something similar.
<html>
<body>
<input type="text" id="userInput">give me input</input>
<button id="submitter">Submit</button>
<div id="output"></div>
<script>
var didClickIt = false;
document.getElementById("submitter").addEventListener("click",function(){
// same as onclick, keeps the JS and HTML separate
didClickIt = true;
});
setInterval(function(){
// this is the closest you get to an infinite loop in JavaScript
if( didClickIt ) {
didClickIt = false;
// document.write causes silly problems, do this instead (or better yet, use a library like jQuery to do this stuff for you)
var o=document.getElementById("output"),v=document.getElementById("userInput").value;
if(o.textContent!==undefined){
o.textContent=v;
}else{
o.innerText=v;
}
}
},500);
</script>
</body>
</html>
