In the given code , I am trying to print the message but after taking input its not printing any message.
<!DOCTYPE html>
<html>
<head>
<title>CSS</title>
</head>
<body>
<form onsubmit="return Ak()">
<input type="text" name="abinash" placeholder="abinash" required id="q"><br><br>
<input type="submit" name="submit" value="submit">
<div id="w"></div>
</form>
<script type="text/javascript">
function Ak()
{
var y=document.getElementById("q").value;
document.getElementById("w").innerHTML="You have typed this password"+y;
}
</script>
</body>
</html>
Pressing the submit button will refresh the page.
event.preventDefault(); use this keyword.
<script type="text/javascript">
function Ak()
{
var y=document.getElementById("q").value;
document.getElementById("w").innerHTML="You have typed this password"+y;
event.preventDefault();
}
</script>
It was working, but after submitting form, all of content disappeared. You need to add event.preventDefault(); to onsubmit attribute of form:
<!DOCTYPE html>
<html>
<head>
<title>CSS</title>
</head>
<body>
<form onsubmit="event.preventDefault(); return Ak()">
<input type="text" name="abinash" placeholder="abinash" required id="q"><br><br>
<input type="submit" name="submit" value="submit">
<div id="w"></div>
</form>
<script type="text/javascript">
function Ak()
{
var y=document.getElementById("q").value;
document.getElementById("w").innerHTML="You have typed this password"+y;
}
</script>
</body>
</html>
event.preventDefault()
It is working, it's just that when you click that submit button the page reloads. I tried it out, and you can fix it by adding e.preventDefault(); to your function, and put (e) as the arg in the function, like so:
<!DOCTYPE html>
<html>
<head>
<title>CSS</title>
</head>
<body>
<form onsubmit="event.preventDefault(); return Ak()">
<input type="text" name="abinash" placeholder="abinash" required id="q"><br><br>
<input type="submit" name="submit" value="submit">
<div id="w"></div>
</form>
<script type="text/javascript">
function Ak()
{
var y=document.getElementById("q").value;
document.getElementById("w").innerHTML="You have typed this password: "+y;
}
</script>
</body>
</html>
Your code works, but the message will disappear because the form is successfully submitted. If you want it to stay on the screen, just return false from the Ak() function:
<!DOCTYPE html>
<html>
<head>
<title>CSS</title>
</head>
<body>
<form onsubmit="return Ak()">
<input type="text" name="abinash" placeholder="abinash" required id="q"><br><br>
<input type="submit" name="submit" value="submit">
<div id="w"></div>
</form>
<script type="text/javascript">
function Ak()
{
var y=document.getElementById("q").value;
document.getElementById("w").innerHTML="You have typed this password"+y;
return false;
}
</script>
</body>
</html>

When I'm running this code it is not showing me the message which I want to display (i.e: res).Suppose I'm giving an input "$code$".Can anyone just help me out?
<!DOCTYPE HTML>
<html>
<head>
</head>
<body>
<h1>Enter a sample message</h1>
<form>
<input type="text" name="a" id="a">
<button onclick="parse()">submit</button>
<p id="a"></p>
</form>
<script>
function parse(){
var msg=document.getElementById("a").innerHTML;
var res=msg.replace("$code$","1101");
document.getElementById("a").innerHTML=res;//this is to print res.
}
</script>
</body>
</html>
Two elements can't have the same ID. Further, an input element's value can not be obtained using the innerHTML property. Also, on clicking the submit button, the page will reload since the form get's submitted. To prevent that, call the function parse in an onsubmit on the <form> tag, and return false from the function.
<!DOCTYPE HTML>
<html>
<head>
</head>
<body>
<h1>Enter a sample message</h1>
<form onsubmit="return parse();">
<input type="text" name="a" id="a">
<button type="submit">submit</button>
<p id="b"></p>
</form>
<script>
function parse(){
var msg = document.getElementById("a").value;
document.getElementById("b").innerHTML = msg;
return false;
}
</script>
</body>
</html>
Check this:
<form>
<input type="text" name="a" class="input_field" id="a">
<button type="button" onclick="parse()">submit</button>
<p id="a"></p>
</form>
<script>
function parse(){
var msg=document.getElementById("a").innerHTML;
var form = document.getElementsByTagName("form")[0]
msg = form.getElementsByClassName("input_field")[0].value;//this is to print res.
}
</script>
I added type="button" to the button to prevent the form from reloading the page

1. problem with the jquery path
2. always put the scripts in the head section
I have two html pages named order.html,check.html and test.js(included in both html files)
When i click on submit button in order.html,amount field value from order.html should get updated/populate into cost field of check.html.
Below is the code i am using but its not working,can someone let me know whats wrong??
order.html
<html>
<head>
<script language="javascript" type="text/javascript" src="test.js"></script>
</head>
<body>
<form name="order" action="check.html" method="get">
name:<input type ="text" id="amount" name="amount">
<input type="submit" value="finish" onclick="cost()" >
</form>
</body>
</html>
check.html
<head>
<script language="javascript" type="text/javascript" src="test.js"></script>
</head>
<body>
<form name="check" action="confirm.html" method="get">
<input type="text" name="cost" id="cost" readonly="readonly">
</form>
</body>
</html>
test.js
function cost(){
var amount= $("#amount").val();
jQuery.load("check.html",function(){
$("#cost").html(amount);
});
}
Your order.html input type submit should be input type button.
Change your test.js to
function cost(){
var amount= $("#amount").val();
$('body').load("check.html",function(){
$("#cost").val(amount);
});
}
And input type="button"
Try this:
order.html:
<html>
<head>
<script language="javascript" type="text/javascript" src="test.js"></script>
</head>
<body>
<div id="main_div">
<form name="order" action="check.html" method="get">
name:<input type="text" id="amount" name="amount"> <input
type="button" value="finish" id="submit_btn">
</form>
</div>
</body>
</html>
Jquery:
$(document).ready(function() {
$('#submit_btn').click(function() {
var amount = $("#amount").val();
$('#main_div').load("check.html", function() {
$('#main_div').find("#cost").val(amount);
});
});
});
I've made a simple test case that is suppose to take the value in the textarea and put it in the div with the id "submit-output" without refreshing, but for some reason it doesn't work.
clicking the submit button doesn't seem to call the postMessage() function, and even reloads the page when I have return false in there at the end.
Can someone please tell me why the submit button is using the default behavior?
<html lang="en">
<head>
<meta charset="utf-8">
<title>Test Case</title>
</head>
<body>
<div id="submit-output">[No output]</div>
<form id="post-form">
<textarea name="post" rows="2" cols="50"></textarea>
<input type=submit value="Submit" id="submitbutton" onclick="postMessage()">
</form>
<script src="http://code.jquery.com/jquery.js"></script>
<script>
$(document).ready(function() {
function postMessage(){
$('#post-form').submit(function(){
console.log("submit");
$('submit-output').html($('#post-form').children('.post').val());
console.log("submitted");
elem.children('.post').val("");
return false;
});
}
});
</script>
</body>
</html>
You shouldn't use the "click" event of a submit button, only the "submit" event of the form.
Also, the $('submit-output') command will try to find a TAG with this name, not the ID, you should use $("#submit-output") instead.
Other important thing: you need to use e.preventDefault() to prevent the event posting the form.
Code working:
<div id="submit-output">[No output]</div>
<form id="post-form">
<textarea id="txtInput" name="post" rows="2" cols="50"></textarea>
<input type="submit" value="Submit" id="submitbutton" />
</form>
Javascript:
$(document).ready(function() {
$("#post-form").submit(function(e) {
e.preventDefault();
$("#submit-output").html($("#txtInput").val());
$("#txtInput").val("");
});
});
DEMO FIDDLE
You don't need onclick="postMessage()" in the input tag, remove that and remove the postMessage() function. Also add event.preventDefault(); like this:
<html lang="en">
<head>
<meta charset="utf-8">
<title>Test Case</title>
</head>
<body>
<div id="submit-output">[No output]</div>
<form id="post-form">
<textarea name="post" rows="2" cols="50"></textarea>
<input type=submit value="Submit" id="submitbutton">
</form>
<script src="http://code.jquery.com/jquery.js"></script>
<script>
$(document).ready(function() {
$('#post-form').submit(function(event){
event.preventDefault();
console.log("submit");
$('#submit-output').html($('#post-form').children('.post').val());
console.log("submitted");
return false;
});
});
</script>
</body>
</html>

Test Case
<div id="submit-output">[No output]</div>
<form id="post-form">
<textarea name="post" rows="2" cols="50"></textarea>
<input type=submit value="Submit" id="submitbutton" >
</form>
<script src="http://code.jquery.com/jquery.js"></script>
<script>
$(document).ready(function() {
function postMessage(){
console.log("submit");
$('#submit-output').html($('#post-form').children('.post').val());
console.log("submitted");
elem.children('.post').val("");
return false;
}
$('#post-form').submit(postMessage);
});
</script>
</body>
