I want to create a TextField in which when I give any input it show on div and this script is showing inputs but not properly...
I don't know where I am making mistakes and I request that please give your answers only in JavaScript please don't use jquery. Thank you .

<body>
<form name="form">
<input name="t" value="" onkeypress="printvalues();">
</form>
<div id="divId"></div>
</body>
</html>
script
function printvalues() {
var div = document.getElementById("divId");
div.innerHTML += form.t.value;
}
Here is my code with output
function printvalues() {
var div = document.getElementById("divId");
div.innerHTML = document.form.t.value;
}
EDIT:The keypress event executes before the value of textbox is changed so use keyup() event which triggers when the key is released instead like
<input name="t" value="" onkeyup="printvalues();">
Your solution is here....
Just change onkeypress to onkeyup
Made below changes and enjoy..
function printvalues(a) {
var div = document.getElementById("divId");
div.innerHTML=a;
}
<input type="text" name="t" onkeyup="printvalues(this.value);">

I am currently learning to use the replace method in JS. I was able to get it to work in a simple function using the console to check the output. However I am now working on making a simple user interface to interact with the function and it has caused some difficulty. I can get the function to accept and re-print the user's text, but the replace portion doesn't seem to be functioning properly as I've written it. Here is the HTML:
<!DOCTYPE html>
<!-- Create a function grabText that replaces the char - with _ -->
<html lang="en">
<meta charset="utf-8">
<head>
<title>HMTL Template</title>
</head>
<body>
<input type="text" id="inputField"
placeholder="Input Text"/>
<button id="clickButton" onclick="grabText();">Run</button>
<p id="outputText"></p>
</body>
</html>
And here is the JS:
var inputText;
function grabText () {
inputText = document.querySelector("#inputField");
document.getElementById("outputText").innerHTML = inputText.value;
inputText.value.replace(/-/g , "_");
document.getElementById("outputText").innerHTML = inputText.value;
}
I suspect there is an issue with where and how I am using .value . Thanks for any help.
keep in mind replace returns a new string, it doesn't change the existing one.
var inputText;
function grabText() {
inputText = document.querySelector("#inputField");
document.getElementById("outputText").innerHTML = inputText.value.replace(/-/g, "_");
}
<input type="text" id="inputField" placeholder="Input Text" />
<button id="clickButton" onclick="grabText();">Run</button>
<p id="outputText"></p>
I'm trying to improve my Javascript by starting a simple web interface, but every time I try to add an event listener to an input field, it breaks my code.
Here's my HTML:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="colors.css">
<script src="spot.js"></script>
</head>
<div id="ask">
Search for an artist to see their top songs:
</div>
<form>
<input type="text" name="artist" id="artist-search">
</form>
<div id="sub">
submit
</div>
</html>
And here's my Javascript:
window.onload = loaded;
var inField;
function loaded() {
document.getElementById("sub").addEventListener("click", search);
inField = document.getElementById("artist-search");
}
//https://api.spotify.com/v1/search?q=tania%20bowra&type=artist
function search() {
alert();
//var query = "//https://api.spotify.com/v1/search?q=";
}
When I add the getElementById to "artist-search", the alert in the search function stops working. Why is this? And is there a better way to get the text in an input field when someone clicks a submit button using vanilla Javascript?
I have this text field hidden with HTML hidden code, now when the user enter an invalid input I use javascript to unhide the text field and display an error message, this is what is suppose to happen.
I have seen a lot of css style like
`style.visibility = 'visible';` and `style.display='block';`
But none of them are working for me what happens is that the error text shows for less than a second and then disappears, any one would like to share their thoughts.
This is the complete code for better understanding, it's still not working in firefox and Edge while IE and Chrome wont do anything, in Firefox, it just blinks once on each button press and that about it.
Javascript:
</script>
function validate(){
var firstname = document.getElementById("fn").value;
if (firstname == "") {
document.getElementById("fn").style.visibility = "visible";
document.getElementById("fn").text = "ERROR";
}
}
function init()
{
var formData = document.getElementById("enqForm");
formData.onsubmit = validate;
}
window.onload = init;
</script>
<!DOCTYPE html>
<html lang="en">
<head>
<script src="scripts.js"></script>
</head>
<body>
<form id="enqForm">
<input id="fn" type="text" placeholder="First Name *" />
<input id="sendbutton" type="submit" value="Enquire" />
</form>
</body>
</html>
Instead of changing the style, you can change the form's type attribute.
Using JavaScript - assuming you want to change lnspan to text:
document.getElementById('lnspan').type = 'text';
Style is not the same as the type attribute.
Also there's two id attributes in your <input>, you may want to change that.
**THAT IS THE ANSWER TO YOUR QUESTION**
<html>
<head>
<script>
function newDoc() {
document.getElementById("hid").type="text";
document.getElementById("hid").value="ERROR";
}
</script>
</head>
<body>
<input type="button" value="Load new document" onclick="newDoc()">
<input type="hidden" id="hid" value="">
</body>
</html>
<!--However this makes your error message as text field which is not good.
What you can do is make the Error into embedded into paragraph <p> so the
users cannot change it and it also looks more professional
<!DOCTYPE html>
<html>
<head>
<script>
function newDoc() {
document.getElementById("te").innerHTML="ERROR";
}
</script>
</head>
<body>
<input type="button" value="Load new document" onclick="newDoc()">
<p id="te">
</body>
</html>
What i want to do is that when i click on the button "1" it should display the number "1" in the textbox above it.
what is wrong with my jquery code?

<input id="textbox" type="text" />

My jquery
$('#1').click(function)({
var txt = $('#textbox');
$('#1').html('txt');
});
Try this code
$('input[type="button"]').click(function() {
var txt = $(this).val();
$('#textbox').val(txt);
});
Will explain your problem with your jQuery code:
Line 1:
You registered with #1 button so this will be triggered on when button 1 is click, I made it generalised
Line 2:
You are getting value from textbox, whereas you are supposed to take value from button text.
Line 3:
You are assigning value in button, whereas you are supposed to assign to textbox and always use val() for input type of control and html() for other html container controls
The above were your errors explained.
Queries welcomed!
Fiddle demo
$(function(){
$('input[type="button"]').click(function(){
$('#textbox').val($(this).val());
});
});
You have to get the value using val() method. Also, you are passing variable txt as string to the html() function which is wrong. Try the below...
var txt = $('#textbox').val();
$('#input1').html(txt);
Try this
$('input[type="button"]').click(function() {
$('#textbox').val($(this).val());
});
You can try this one
$('div').on('click', 'input', function () {
$('#textbox').val(this.value);
});
I am trying to get the user to put something into the text area and the output should be what he wrote repeapiting x amount of times, but I get an error "document.forme is undefined".
Can you please help me understand why it is undefined?
My code:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>input home work</title>
<script type="text/javascript">
var help= document.forme.tryout.value;
for (x=1; x<=10;x++){
function numberCheak (){
document.write("this is"+" "+help++);
}
}
</script>
</head>
<body>
<form name="forme">
<input name="tryout" type="text" />
<input type="button" value="click me" onClick="numberCheak();"/>
</form>
</body>
</html>
Ok, you have a few problems. The first is that you are trying to access a form element that doesn't exist yet: the script is above the form element, so the form doesn't exist when you try to get it. If you move the script to the bottom of the page it will work better.
Second, the loop should be inside the function, not wrapped around the function.
Third, document.write has weird side effects and causes the document to be rewritten and will stop the script from continuing correctly.
Here's my revised script
function numberCheak() {
var help = document.forme.tryout.value;
for (var x = 1; x <= 10; x++) {
document.getElementById("output").innerHTML += help;
}
}
and the HTML form that goes with it
<form name="forme" id="forme">
<input name="tryout" type="text" />
<input type="button" value="click me" onclick="numberCheak();" />
<span id="output"></span>
</form>
You can see it in action on jsFiddle.
Forms are stored in collection and can be accessed like this:
var form = document.forms[i];
or
var form = document.forms[name];
In your case, i is 0 and name is forme.
