JS code
'use strict';
$(document).ready(function() {
});
function change() {
document.getElementById('the-name').innerHTML = document.getElementById('name');
}
HTML code
<p> What's your name? <input type="text" placeholder="Name" id = "name"></input></p>
<button id="button" onclick= "change(document.getElementById('name'))"> Answer </button>
<p>Hello <span id = "the-name"></span>,</p>
With the code above, I get the result in the title whenever I try to run it by clicking the button. Could someone point me to the right direction by telling me what I am doing wrong? Much appreciated, thank you!
Your problem is that you are assigning a HTMLInputElement to the innerHTML of your element instead of a text or a HTML content in the line:
document.getElementById('the-name').innerHTML = document.getElementById('name');
You need to get the input value:
document.getElementById('the-name').innerHTML = document.getElementById('name').value;
Demo:
'use strict';
$(document).ready(function() {});
function change() {
document.getElementById('the-name').innerHTML = document.getElementById('name').value;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p> What's your name? <input type="text" placeholder="Name" id="name"></input>
</p>
<button id="button" onclick="change(document.getElementById('name'))"> Answer </button>
<p>Hello <span id="the-name"></span>,</p>
You are assigning the whole HTML-Input Element to your <span>.
You have to use the value property of you HTML-Input Element to get its value.
document.getElementById('the-name').innerHTML = document.getElementById('name').value

I'm trying to simply get the value of an input and put it into a p tag.but it looks like that I'm not getting anything from the input tag
<body>
<input type="text" id="text">
<button class="button" onclick="sum();">click</button>
<p id="lblResult">Result</p>
</body>
<script>
const text = document.getElementById('text').value;
function sum()
{
document.getElementById('lblREsult').innerHTML = text;
}
</script>
You get value from input on page load when it's empty, move document.getElementById('text').value into sum function.
And you have an typo, lblREsult !== lblResult
function sum() {
const text = document.getElementById('text').value;
document.getElementById('lblResult').innerHTML = text;
}
<input type="text" id="text">
<button class="button" onclick="sum();">click</button>
<p id="lblResult">Result</p>
Say I have this text box:
<input type="text" id="myText" placeholder="Enter Name Here">
Upon pressing a button, I would like to send the value entered into this div:
<div id="text2"></div>
I'm not entirely sure how to do this. Do I create a function and call it to the div? How would I do that?
Could someone clear this up for me? Thanks.
Add an onclick to your button:
<input type="button" id="somebutton" onclick="addText()">
Then write the javascript:
function addText()
{
document.getElementById('text2').innerHTML = document.getElementById('myText').value;
}
Solution using onclick event:
<input type="text" id="myText" placeholder="Enter Name Here">
<div id="text2"></div>
<button id="copyName" onclick="document.querySelector('#text2').innerHTML = document.querySelector('#myText').value" value="Copy Name"></button>

You can manipulate the content inside the div from javascript code. Your button should trigger a function (using the onclick event), which would access the specific div within the DOM (using the getElementById function) and change its contents.
Basically, you'd want to do the following:
<!DOCTYPE html>
<html>
<script>
function changeContent() {
document.getElementById("myDiv").innerHTML = "Hi there!";
}
</script>
<body>
<div id="myDiv"></div>
<button type="button" onclick="changeContent()">click me</button>
</body>
</html>
Mark D,
You need to include javascript to handle the button click, and in the function that the button calls, you should send the value into the div. You can call $("#myText").val() to get the text of the text box, and $("#txtDiv").text(txtToAppend) to append it to the div. Please look at the following code snippet for an example.
function submitTxt() {
$("#txtDiv").text($("#myText").val())
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="myText" placeholder="Enter Name Here">
<button onclick = "submitTxt()"> Submit </button>
<div id="txtDiv"> </div>
HTML could be:
<input type='text' id='myText' placeholder='Enter Name Here' />
<input type='button' id='btn' value='click here' />
<div id='text2'></div>
JavaScript should be external:
//<![CDATA[
var pre = onload; // previous onload? - window can only have one onload property using this style of Event delegation
onload = function(){
if(pre)pre();
var doc = document, bod = doc.body;
function E(e){
return doc.getElementById(e);
}
var text2 = E('text2'); // example of Element stored in variable
E('btn').onclick = function(){
text2.innerHTML = E('myText').value;
}
}
//]]>
I would recommend using a library like jQuery to do this. It would simplify the event handling and dom manipulation. None the less, I will include vanilla JS and jQuery examples.
Assuming the HTML in the body looks like this:
<form>
<input id="myText" type="text" placeholder="Enter Name Here">
<br>
<input type="submit" id="myButton">
</form>
<div id="text2"></div>
The Vanilla JS example:
//Get reference to button
var myButton = document.getElementById('myButton');
//listen for click event and handle click with callback
myButton.addEventListener('click', function(e){
e.preventDefault(); //stop page request
//grab div and input reference
var myText = document.getElementById("myText");
var myDiv = document.getElementById("text2");
//set div with input text
myDiv.innerHTML = myText.value;
});
When possible avoid using inline onclick property, this can make your code more manageable in the long run.
This is the jQuery Version:
//Handles button click
$('#myButton').click(function(e){
e.preventDefault(); //stop page request
var myText = $('#myText').val(); //gets input value
$('#text2').html(myText); //sets div to input value
});
The jQuery example assumes that you have/are adding the library in a script tag.
I am new to "html" and "Javascript".
<p id="pid"></p>
<script>
abc="hello";
document.getElementById("pid").innerHTML=abc;
</script>
<input type="text"
value="<script>document.getElementById("pid").innerHTML</script>"/>
How the code gets executed in the above case.
Looks like you are trying to set a value of the input field to be equal to the content of the pid paragraph. In this case you should set value property of the HTMLInputElement. You can get a reference to it using getElementById (there are many ways to get this element object) which you already know how to use. For example:
<p id="pid"></p>
<input type="text" id="input" />
<script>
var abc = "hello";
var pid = document.getElementById("pid");
pid.innerHTML = abc;
document.getElementById("input").value = pid.innerHTML;
</script>
the content of the 'value' attribute is just text, the browser will not interpret the JS code.
You can use the DOM instead:
<p id="pid"></p>
<script>
abc="hello";
document.getElementById("pid").innerHTML=abc;
</script>
<input id = "myInput" type="text" value="" />
<script>
document.getElementById("myInput").value = abc;
//OR : document.getElementById("myInput").value = getElementById("pid").innerHTML;
</script>
see : Accesing the javascript variable in html tag
I think you're trying to do this:
<script>
function myFunction(){
var abc="hello";
document.getElementById("pid").innerHTML=abc;
}
</script>
<p id="pid"></p>
<input type="button" value="Click Me" onclick="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()">
x is undefined in your function, it should be document.getElementById('fname').
And if you want to change the div each time you press the key, use onkeyup or onkeypress instead of onchange.
You may change x.value to document.getElementById("fname").value, if I understand your question correctly.
<head>
<script type="text/javascript">
function input(){
var input_taker = document.getElementById('email').value;
document.getElementById('display').innerHTML = input_taker;
}
</script>
</head>
<form method="post" action="#">
<input type="text" name="email" placeholder="email#example.com" id="email" onchange="input()">
<input type="submit" name="save" value="save">
</form>
<div id="display"></div>
Ok, so check this out - http://jsfiddle.net/2ufnK/2/
The issue is that you need to define x here,
var x = document.getElementById("fname");
x now references to the html object.
Then you can just call the, ".value", method to get its text. Then everything else works the way you've written it.
I am trying to run this code.
the code should take a string as input and put that input to a div and calculate the width of the div.
here is code i have used.
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
</head>
<body>
<input type="text" value="" name="input">
<input type="submit" value="submit" name="submit">
<script>
var elem = '<div id="divitem" style="width:auto;"></div>';
$('body').append($(elem));
$("submit").click(function () {
var text = $(this).text();
value= $("input").val(text);
alert(value);
});
</script>
</body>
</html>
but i am not getting any output. how to do this?
please help me.
Try this paps!
Demo
This is similar to your problem.
HTML
<div id="container">
<input type="text" value="" id="inputtext">
<input type="button" value="submit" id="submit">
</div>
Script
$(function(){
var elem = '<span id="divitem"></span>';
$('#container').append($(elem));
$("#submit").click(function () {
$('#divitem').html($('#inputtext').val());
alert($('#divitem').width());
});
});
Here's a fiddle
To obtain value from a text field you need to use this,
$('input[name="input"]').val();
and not .text()
To answer your second question, you need to use this
$('#divitem').attr('style');
or
$('#divitem').attr('width');
The problem is here:
$("submit").click(function () {
var text = $(this).text();
value= $("input").val(text);
alert(value);
});
$(this) refers to the element that you select, which is the submit button.
You should replace the first line of the function with
$('input[name="input"]').text();
Finally, setting the html content of the div, will be done this way:
elem.html(test);
Hope this helps. Have a great day.
I have created a jsFiddle for your question http://jsfiddle.net/N4zFZ/ in JavaScript
You can calculate width by
`var width = $('#divId').attr('width');`
