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);
});
});
});

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>
<!DOCTYPE html>
<html>

<title>Function</title>
<script type="text/javascript">
function sum(x,y) {
var z = x+y;
document.write("Sum is"+z);
}
</script>
</head>
<body>
<form>
<input type="" id="t1" name=""/>
<input type="" id="t2" name=""/>
<input type="button" onclick="sum(t1.value,t2.value)" value="Click me"/>
</form>
</body>
</html>
Hi Guys, I am a beginner with JavaScript and I'm facing this little problem. If I enter 5 and 5 the result is 55. But I want to sum up these values.
As #TonyDong said, uses parseInt to convert the string to int if desired input is integer.
To make your function works better, you need to validate the inputs first before sum.
Below is one example:
make the type of two inputs are 'number'
checkValidity() for the form or two inputs in function=sum. if validated, sum the values, if not, return error.
<!DOCTYPE html>
<html>
<head>
<title>Function</title>
<script type="text/javascript">
function sum(x,y)
{
if(document.getElementById("submit").checkValidity()) {
var z = parseInt(x)+parseInt(y);
document.write("Sum is "+z);
}
else {
document.write("Input value must be Int!");
}
}
</script>
</head>
<body>
<form id="submit">
<input id="t1" name="" type="number"/>
<input id="t2" name="" type="number"/>
<input type="button" onclick="sum(t1.value,t2.value)" value="Click me"/>
</form>
</body>
</html>
You should covert x and y to integers first, like parseInt(x) and parseInt(y) while doing the summation.
Then, instead of document.write, you can use console.log.
<!DOCTYPE html>
<html>
<head>
<title>Function</title>
<script type="text/javascript">
function sum(x,y) {
var z = parseInt(x)+parseInt(y);
console.log("Sum is",z);
}
</script>
</head>
<body>
<form>
<input type="" id="t1" name=""/>
<input type="" id="t2" name=""/>
<input type="button" onclick="sum(t1.value,t2.value)" value="Click me"/>
</form>
</body>
</html>
form.html
function validate() {
var name = document.Myform.name.value;
document.write(name);
}
<html>
<head>
<script src="validations.js"></script>
</head>
<body>
<form name="Myform" onsubmit="return validate()">
Enter name: <input type="text" name="name" /><br/><br/>
<input type="submit" />
</form>
</body>
</html>
Output: undefined
After typing my name in input box it is showing undefined.
The Problem is on your input. you should change t he name=="name" to name="name". Then change your validate function to us getElementsByName. See the code below:
<html>
<head>
<script>
function validate(){
var name=document.getElementsByName('name')[0].value;
document.write(name);
}
</script>
</head>
<body>
<form name="Myform" onsubmit="return validate()">
Enter name: <input type="text" name="name"><br><br>
<input type="submit" />
</form>
</body>
</html>
dont make use of name attribute it old way of W3C standard, from long time they are suggesting make use of id attribute.
you code needs to be like this
<input type="text" id="txtname"/><br><br>
and javascript like
var name=document.getElementById("txtname").value;
You just have to fix your name=="name". In HTML we use = to assign attribute values/
function validate() {
var name = document.Myform.name.value;
document.write(name);
}
<html>
<head>
<script src="validations.js"></script>
</head>
<body>
<form name="Myform" onsubmit="return validate()">
Enter name: <input type="text" name="name" /><br><br>
<input type="submit" />
</form>
</body>
</html>
the validate function doesn't return anything as would usually be the case for this type of event hander ~ it will instead simply write the name ~ is that the desired result?
<html>
<head>
<title>form validation</title>
<script src="validations.js"></script>
<script>
function validate(e){
e.preventDefault();
var name=e.target.querySelector('input[ name="name" ]').value;
document.write( name );
return true;
}
</script>
</head>
<body>
<form name="Myform" onsubmit="return validate(event)">
Enter name: <input type="text" name="name"/><br><br>
<input type="submit" />
</form>
</body>
</html>
I am trying to use ajax but it is not working when I clicks the button it does not show the alert box on browser.
<html>
<head>
<title>Ajax</title>
<script scr="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
</head>
<body>
Name: <input type="text" id="data">
<input type="submit" id="sub" value="save">
<script>
$(document).ready(function () {
$('#sub').click(function () {
alert('ok');
});
});
</script>
</body>
</html>
Please try the below code
<html>
<head>
<title>Ajax</title>
<script src="https://code.jquery.com/jquery-1.9.1.min.js"></script>
<script>
$(document).ready(function(){
$('#sub').click(function(){
alert('ok');
});
});
</script>
</head>
<body>
Name: <input type="text" id="data" >
<input type="submit" id="sub" value="save">
</body>
</html>
1. problem with the jquery path
2. always put the scripts in the head section
i want to write the value in textbox under it,how can i do it?thanks in advance
i wrote this codes:
<html>
<head>
<script language="javascript">
function show (text){
document.write("text");
}
</script>
</head>
<body>
<input type=textbox name=textbox value="Insert Name"/>
<input type=button name=button value="OK" onclick=show(textbox.value)/>
</body>
</html>
first of all: document.write replaces document content, use window.alert or such
next, consider enclosing fields in the <form> and then use show(this.form.textbox.value)
thats besides other scripting errors :)
Modify your html like this:
<input type=textbox name=textbox value="Insert Name" id="txt" />
<span id="spn"></span>
<input type=button name=button value="OK" onclick="show();" />
And JavaScript like this:
function show(){
document.getElementById('spn').innerHTML = document.getElementById('txt').value;
}
Something like this should work: Working example
<html>
<head>
<script language="javascript">
function show (text){
document.getElementById("text").innerHTML = text;
}
</script>
</head>
<body>
<input type=textbox name=textbox id=textbox value="Insert Name"/>
<input type=button name=button value="OK" onclick="show(document.getElementById('textbox').value)"/>
<div id="text"></div>
</body>
</html>
