Retrieve data after pressing submit button - javascript

<div class="chat-input-holder">
<textarea class="chat-input"></textarea>
<input type="submit" value="Send" class="message-send"/>
</div>
How to retrieve data in textarea field after clicking on submit button. Using jquery, ajax?

This code should work:
function getdata(Event){
Event.preventDefault()
let chatInput = $('#chat-input').val();
$('#result').text(chatInput)
}
$('#message-send').click(getdata);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.0/jquery.min.js"></script>
<form class="chat-input-holder"> <!-- replace div with form -->
<textarea class="chat-input" id="chat-input"></textarea>
<input type="submit" value="Send" id="message-send" class="message-send"/>
</form>
<p> for the example we will place the text on the div bellow. but use the data however you like</p>
<div id='result'>
</div>
Note that I changed the div tag into a form tag, and added some IDs.

You can find here a solution using jQuery. The output is currently store in a div with id="out", you can customize the code.
document.forms["chat-input-holder"].addEventListener('submit', e => {
e.preventDefault();
let text = $(".chat-input").val();
$("#out").html(text);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form id="chat-input-holder">
<textarea class="chat-input"></textarea>
<input type="submit" value="Send" class="message-send"/>
</form>
<div id="out"></div>

Toggle html button depending if textarea is filled or empty

Hey the task i try to achieve is to activate and deactivate a button depending on, if there is text in a textarea or not.
Here the code I'm trying to get going.
var button = document.getElementById("button_01");
var textarea = document.getElementById("textarea_01");
$(button).prop('disabled', true);
textarea.addEventListener('keyup', function() {
button.disabled = !this.value;
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="div_01">
<h1>String Editor</h1>
<textarea id="textarea_01" rows="5" placeholder="Paste your string here"></textarea>
</div>
<div id="div_02">
<h1>Options</h1>
<button id="button_01" type="button" value="submit">
Modify
</button>
</div>
and here a fiddle: Fiddle
What I'm really not understanding here is, why the button which I disabled in the js part is still active
I'm an absolute html/js/web developement newbie, so please give some explanation.
Thanks in advance
The jsFiddle doesn't work because there's no jQuery CDN link.
You can find an updated version, witch includes the jQuery CDN here.
You're using jQuery to disable the button on page-load.
I'll recommend using HTML for that:
<button id="button_01" type="button" value="submit" disabled>
Then, your code appears to work just fine because there's no jQuery needed anymore:
var button = document.getElementById("button_01");
var textarea = document.getElementById("textarea_01");
textarea.addEventListener('input', function() {
button.disabled = !this.value;
});
<div id="div_01">
<h1>String Editor</h1>
<textarea id="textarea_01" rows="5" placeholder="Paste your string here"></textarea>
</div>
<div id="div_02">
<h1>Options</h1>
<button id="button_01" type="button" value="submit" disabled>
Modify
</button>
</div>
Note;
Changed event from keyup to input so things like right-click and paste will trigger the event. (Thx to #freedomn-m)
Try like this.
var button = document.getElementById("button_01");
var textarea = document.getElementById("textarea_01");
button.disabled = true;
textarea.addEventListener('keyup', function() {
button.disabled = !this.value;
});
<div id="div_01">
<h1>String Editor</h1>
<textarea id="textarea_01" rows="5" placeholder="Paste your string here"></textarea>
</div>
<div id="div_02">
<h1>Options</h1>
<button id="button_01" type="button" value="submit">
Modify
</button>
</div>

Why is my button that calls a function on click making my page reload

I am working on a form that uses javascript to create a paragraph. For some reason, when I click my button, it forces my page to reload. Could you anyone let me know what I'm doing wrong here?
console.log('everything is linked')
function createParagraph() {
console.log('function called');
var wordOne=document.getElementById('textOne').value
var wordTwo=document.getElementById('testTwo').value
var paragraph = '<p>My first word is' + wordOne+'. My Second word is '+ wordTwo+'.</p>';
document.getElementById('answer').innerHTML= paragraph
}
<body>
<form action="">
<input id='textOne' type="text">
<input id='textTwo' type="text">
<button onclick="createParagraph()">Click Me</button>
</form>
<div id="answer"></div>
<script src="app.js"></script>
</body>
The default behavior of a <button> inside a <form> is to submit that form. Set the button's type to explicitly not be a "submit":
<button type="button" onclick="createParagraph()">Click Me</button>
Additionally, if you have no use for the actual <form> (don't want to submit it) then it's probably best to just remove it:
<body>
<input id='textOne' type="text">
<input id='textTwo' type="text">
<button type="button" onclick="createParagraph()">Click Me</button>
<div id="answer"></div>
<script src="app.js"></script>
</body>
That way there's nothing to accidentally be submitted in the first place.
Your button acts as a submit button, so your form is being submitted. To prevent this, you can use attribute onSubmit on your form and prevent sending form.
<form onSubmit="return false">
Because the button is in a form and the form is probably submitted.
add the type="button" to not submit the form.
console.log('everything is linked')
function createParagraph() {
console.log('function called');
var wordOne=document.getElementById('textOne').value
var wordTwo=document.getElementById('testTwo').value
var paragraph = '<p>My first word is' + wordOne+'. My Second word is '+ wordTwo+'.</p>';
document.getElementById('answer').innerHTML= paragraph
}
<body>
<form action="">
<input id='textOne' type="text">
<input id='textTwo' type="text">
<button type="button" onclick="createParagraph()">Click Me</button>
</form>
<div id="answer"></div>
<script src="app.js"></script>
</body>

How to clear textarea field onclick in AJAX?

How to clear textarea field onclick? the problem is I am using AJAX. it won't reload the page. can anyone help me to solve this problem.
<div class="write_comment" style="">
<textarea type="text" id="form_task_comment" name="form_task_comment" value="" placeholder="Write your comment here..."></textarea>
<div class="buttons" style="float:right">
<button id="btn_comment_submit" class="btn btn-default btn hoverable btn-sm btn_comment_submit" style="margin:0rem;" type="submit">Add Comment</button>
</div>
</div>
Try this. Click on button to clear Textarea
$('.clearText').click(function(){
$("#form_task_comment").val('');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class="clearText">Click Here To Clear Textarea</button>
<br>
<textarea id="form_task_comment">This is textarea</textarea>
In case you do not want to use jQuery. And the other posts above do not mention how to reset your textarea ON send. When you bind onclick, it would clear the text BEFORE sending. Therefore you need to use form onsubmit
var textArea = document.getElementById("form_task_comment")
var form = document.getElementById("form-name")
form.addEventListener("submit", function(event) {
textArea.value = "";
event.preventDefault();
}, false)
<div class="write_comment" style="">
<form id="form-name" >
<textarea type="text" id="form_task_comment" name="form_task_comment" value="" placeholder="Write your comment here..."></textarea>
<div class="buttons" style="float:right">
<button id="btn_comment_submit" class="btn btn-default btn hoverable btn-sm btn_comment_submit" style="margin:0rem;" type="submit">Add Comment</button>
</div>
</form>
</div>
Simply just replace textarea.value with nothing when button is clicked??
html code:
<input type="button" value="Clear Text" onclick="eraseText();"></input>
Javascript:
function eraseText()
{
document.getElementById("form_task_comment").value = "";
}
You can simply clear the value of text area using .val() like this
$("#form_task_comment").val('');
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<textarea id="form_task_comment">This is textarea</textarea>
Add this line of code wherever you want to clear the text area

How to add text into a div using a html form?

Adding the insertion of input type text into the div title on the same screen. Attempted broken function to they turn the input into a variable and use it to fill in the div.
<body>
<div class="form">
Form <br><br>
<form name="input" action="javascript:alert(titleValue);">
Title: <input type="text" name="title" class="titleInsert">
<input type="submit" value="Submit">
</form>
</div>
<div class="offer_display">
<div class="title" id= title></div>
</div>
</body>
<script>
var titleValue="";
$('#titleInsert').on("change", function () {
titleValue=$(this).val();
$("#title h3").text("titleValue");
});
</script>
</html>
Another problem with you code is, that you have to use "input" event and not "change".
See working code on fiddle: http://jsfiddle.net/z037qv3n/
<body>
Form <br><br>
<form name="input" action="javascript:alert(titleValue);">
Title: <input type="text" name="title" id="titleInsert">
<input type="submit" value="Submit">
</form>
<div class="title" id="title"></div>
</body>
<script>
var titleValue="";
$('#titleInsert').on("input", function () {
titleValue=$(this).val();
$("#title").text(titleValue);
});
</script>
</html>
Change your code for $('div.title').html(titleValue);
Live Demo : JSFIDDLE
You have to include jQuery library in your head section like this
<script src="http://code.jquery.com/jquery-1.10.2.js"></script>
There are lot of mistakes in your code please see below:
First mistake you should put your jQuery inside ready function.
Second mistake there is no such id #titleInsert it is a class so you have to do .titleInsert
Third mistake there is no tag h3 in #title
Fourth mistake you should use .keyup event instead .change event
Replace your jQuery code with following :
<script type="text/javascript">
$(document).ready(function(){
var titleValue="";
$('.titleInsert').on("keyup", function () {
titleValue=$(this).val();
$("#title").text("titleValue");
});
});
</script>

Form with two submit buttons doing two different things

I have a form that I have two buttons on. One button should take the user to one php script and the other button would take the user two a different php script. However for some reason the buttons aren't doing anything. Here is the code.
<script language="Javascript">
function OnButton1()
{
document.contactform.action = "../scripts/email-info.php"
// document.Form1.target = "_blank"; // Open in a new window
document.contactform.submit(); // Submit the page
return true;
}
function OnButton2()
{
document.contactform.action = "../scripts/email-info2.php"
//document.contactform.target = "_blank"; // Open in a new window
document.contactform.submit(); // Submit the page
return true;
}
</script
Then here is the actual form code:
<form id="contact-form" name="contactform" method="post">
<fieldset>
<div id="holder">
<div id="formLeft">
<div class="txtlabel">Name* </div><div class="input-bg"><input type="text"
name="name" id="name" required></div>
</div>
</div>
<div id="msgbox">
<div class="txtlabel">Tell Us About Your Business Needs</div>
<div class="message-bg">
<textarea name="message" id="message" rows="9" cols="56" required></textarea><input
name="formpage" type="hidden" value="<?=$pagename;?>" />
</div></div><div style="clear:both"></div><br /><br />
<input src="/submitbtn.jpg"
name="submit" value="View Now" class="submit-button" onclick="OnButton1();"/>
<input src="/submitbtn.jpg"
name="submit" value="Download Now" class="submit-button2" onclick="OnButton2();" />
</fieldset>
</form>
I've removed some of the submission fields to make it more easily viewable. But I get nothing when I click either button...Any thoughts??
problem is in input:
<input src="/submitbtn.jpg"
name="submit" value="View Now" class="submit-button" onclick="OnButton1();"/>
When you have a form:
document.contactform.submit
Javascript returns the input with name submit, not the submit function.
You could change the name of the input:
<input src="/submitbtn.jpg"
name="yourName" value="View Now" class="submit-button" onclick="OnButton1();"/>
Also, your inputs are not buttons, check this.
Update
This question mentions HTML5 formaction attribute:
<form action=#">
<buton formaction="script-1.php">submit one</button>
<buton formaction="script-2.php">submit two</button>
</form>
I'm surprised no one mentioned formaction. It is a legal attribute (in HTML5) for the input and button tag in submit/image state and can be used to send form data to a different action page. http://mdn.beonex.com/en/HTML/Element/input.html (it is also valid in button too).
<form action=#">
<buton formaction="script-1.php">submit one</button>
<buton formaction="script-2.php">submit two</button>
</form>
In case you need to support IE9-, you simply can polyfill this, using webshims.
<script src="webshims/polyfiller.js"></script>
<script>
webshims.polyfill('forms');
</script>
<!-- now it also works with IE8/9 and other legacy browsers -->
<form action=#">
<buton formaction="script-1.php">submit one</button>
<buton formaction="script-2.php">submit two</button>
</form>
The reference to your form is
document.forms.contactform
and not
document.contactform
So, for example, the submit button should be:
document.forms.contactform.submit();
// ^^^^^
The same correction should be applied to other references.
