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>
Suppose a function trigger on Click button
<!DOCTYPE HTML>
<html lang="en">
<!--getElementsByTagName.html-->
<head>
<title>getElementsByTagName.html</title>
<meta charset="UTF-8"/>
<link rel="stylesheet" type="text/css" href="getElementsByTagName.css"/>
<script type="text/javascript">
//<![CDATA[
function getData(){
inputTag=document.getElementsByTagName("input");
divOutput=document.getElementById("output");
alert(inputTag.length);//length of input Tag
for(i=0;i<inputTag.length-1;i++){
if((inputTag[i].value=="") || (inputTag[i+1].value=="")){
alert("Please Enter Value");
}else{
a=inputTag[i].value;
b=inputTag[i+1].value;
}
}
$("#output").css("display","block");
divOutput.innerHTML="<strong>"+a+"<\/strong>";
divOutput.innerHTML+="<br\/>"+"<strong>"+b+"<\/strong>";
}//end function
//]]>
</script>
</head>
<body>
<form action="">
<fieldset>
<legend>Example getElementsByTagName</legend>
<label>Name</label>
<input type="text" id="txtName"/>
<label for="txtName">Password</label>
<input type="password" id="txtPassword"/>
<button type="button" onclick="getData()">
Submit
</button>
</fieldset>
<div id="output">
</div>
</form>
</body>
</html>
Is this right?? $("#output").css("display","block");
This code not working i.e. after click on submit button it doesn't show the output div?
Add this code:
$( "#output" ).on( "click", function() {
this.css("display", "block");
});
i am trying to pass the values from one html page to another html page but i am getting some errors..
below is my html page one code:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function first() {
location.href = "onclick2.html";
}
</script>
</head>
<body>
<button onclick="first()" >Home</button>
<form action="onclick2.html" method="post">
<input type="text" name="sender" />
<input type="submit" value="send"/>
</form>
</body>
</html>
below is my html page 2 code
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function first() {
location.href = "onclick.html";
}
</script>
</head>
<body>
<button onclick="first()">Home2</button>
<form action="onclick.html" method="get">
<input type="text" name="reciver" />
</body>
you can pass value in url and transfer it as given below :
location.href = "http://www.domainname.com/login.html?FirstName=admin&LastName=admin"
Trigger the image when i click submt button and in current active tab
<form name="myform" onsubmit="return onsubmitform();">
<input type="submit" name="operation" onclick="document.pressed=this.value" value="GetCATHY"/>
</form>
<script type="text/javascript">
function onsubmitform()
{
if(document.pressed=='GetCATHY')
{
document.pressed.action="img src=a.jpg";
}
}
You can easily do this using jQuery.
However this is pretty simple stuff so I suggest doing a bit of reading and practice on basic html.
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#submit").click(function(){
$("#hidden").show();
});
});
</script>
<style type="text/css">
.hidden {
display: none;
}
</style>
</head>
<body>
<form><input type="submit" id="submit"></form>
<div id="hidden" class="hidden">IMAGE</div>
</body>
</html>
I'm trying to get text from a text input, append it to a URL, and go to that URL, using Javascript. But when I submit, it appears to just reload the page.
http://jsfiddle.net/E3vv6/
<html>
<head>
<title>Home</title>
<link rel="stylesheet" href="main.css" />
<script type="text/javascript">
function loadSearchResult(searchToLoad) {
window.location = "https://encrypted.google.com/search?q=" + searchToLoad;
}
</script>
</head>
<body>
<form onsubmit="loadSearchResult(document.getElementById('googleBox').value)" method="post">
<fieldset>
<legend>Search</legend>
<input type="text" id="googleBox">
</fieldset>
</form>
</body>
</html>
You need to use event.preventDefault() in the submit function.
Live Demo (click).
Further, inline js (onsubmit in your html) is bad practice for a lot of reasons. Here are some: https://www.google.com/search?q=Why+is+inline+js+bad%3F
If would be better to get a reference to the form with javascript and attach the event listener.
<form id="myForm">
<input type="submit" value="Submit">
</form>
JavaScript:
var myForm = document.getElementById('myForm');
myForm.addEventListener('submit', function(e) {
myFunction();
e.preventDefault();
});
function myFunction() {
console.log('submitted!');
}
You need to prevent the default behaviour of the onsubmit.
You could use return false:
<html>
<head>
<title>Home</title>
<link rel="stylesheet" href="main.css" />
<script type="text/javascript">
function loadSearchResult(searchToLoad) {
window.location = "https://encrypted.google.com/search?q=" + searchToLoad;
return false;
}
</script>
</head>
<body>
<form onsubmit="return loadSearchResult(document.getElementById('googleBox').value)" method="post">
<fieldset>
<legend>Search</legend>
<input type="text" id="googleBox">
</fieldset>
</form>
</body>
</html>
