I have a simple form to take user input. User must fill very fields in that form. If they don't, javascript gives the alert message but it's not working. I am not getting alert message if I submit the form empty. Here's my form.html:
</style>
<script type="text/javascript">
function Validate(){
if(document.simple_form.session.value == "" ||
document.simple_form.hostname.value == "" ||
document.simple_form.username.value == ""
document.simple_form.password.value == "")
{
alert("Please fill out all fields before clicking Load!");
return false;
}
}
</script>
</head>
<body>
<form action="." method="post" onsubmit="return Validate();" name="simple_form">
{% csrf_token %}
<fieldset>
<legend>Session</legend>
<label for="input-one" class="float"><strong>Session Name:</strong></label><br />
<input class="inp-text" name="session" id="sess" type="text" size="30" /><br />
<label for="input-two" class="float"><strong>RemoteHost:</strong></label><br />
<input class="inp-text" name="hostname" id="host" type="text" size="30" onblur="if(this.value=='') { this.value='ngs.pradhi.com:/upload' }" onfocus="if(this.value=='ngs.pradhi.com:/upload') { this.value='' }" value="ngs.pradhi.com:/upload" />
<label for="input-three" class="float"><strong>Username:</strong></label><br />
<input class="inp-text" name="username" id="user" type="text" size="30" />
<label for="input-four" class="float"><strong>Password:</strong></label><br />
<input class="inp-text" name="password" id="pass" type="password" size="30" />
</fieldset>
<p><input class="submit-button" type="submit" value="Load" /></p>
<p><input class="save-button" type="reset" name="cancel" value="Cancel" /></p>
</form>
Is there something I am missing?
You're missing a final || in your Validate() function.
I've got a working jsfiddle here (I added a couple of </br>'s too).

I want us javascript to submit my html form.
I try two method.
The first one is good for me.
function formSubmit() {
document.getElementById("myForm").submit()
}
<form id="myForm" action="" method="get">
firstname：<input type="text" name="firstname" size="20"><br />
Last name：<input type="text" name="lastname" size="20"><br />
<br />
<input type="button" onclick="formSubmit()" value="submit" >
</form>
otherwise,the second one can not work for me
window.addEventListener("click", function(event){
event.preventDefault();
document.getElementById("myForm2").submit() }
)
});
<form id="myForm2" action="" method="get">
firstname：<input type="text" name="firstname" size="20"><br />
Last name：<input type="text" name="lastname" size="20"><br />
<br />
<input type="button" value="submit" >
</form>
All i want to do is to use addeventlistner method to submit form
Here is a way to do it.
function formSubmit() {
document.getElementById("myForm").submit()
}
document.getElementById("submitBtn").addEventListener("click", function(event) {
event.preventDefault()
document.getElementById("myForm").submit()
})
<form id="myForm" action="https://google.com" method="get">
First name:
<input type="text" name="firstname" size="20">
<br /> Last name：
<input type="text" name="lastname" size="20"><br />
<br />
<button id="submitBtn" type="button" onclick="formSubmit()">Submit</button>
</form>
You can use input type like this
<form id="myForm2" action="" method="get">
firstname：<input type="text" name="firstname" size="20"><br />
Last name：<input type="text" name="lastname" size="20"><br />
<br />
<input type="submit" value="submit" >
</form>
and submit event for related form
document.getElementById("myForm2").addEventListener("submit", function() {
console.log("submitted")
})
I have HTML code which displays a pre-compiled login form. Is it possible to improve this code in order to make the login automatic, so it autofills the user information (name, password)?
<html><body>
<form
id="myForm"
action="http://***.***.***.***/***/****/*******="
method="post">
Account name:<br>
<input name="****" value="****" />
<br>
Password:<br>
<input type="password" name="pwd" value="****" />
<br><br>
<input type="submit" value="Login">
</form>
</body></html>
What you can do is use JavaScript:
function login() {
document.getElementById("username").value = "username";
document.getElementById("password").value = "password";
}
<html><body>
<form id="myForm" action="http://***.***.***.***/***/****/*******=" method="post">
Account name:<br>
<input name="****" value="****" id="username" />
<br>
Password:<br>
<input type="password" name="pwd" value="****" id="password"/>
<br><br>
<input type="submit" value="Login" onclick="login()" />
</form>
</body></html>
you can also use the jQuery submit event for your form. In your javascript use:
$(document).ready(function(){
$("#myForm").submit();
});
Of course, just click on the button on load:
<html><body onload="document.getElementById('login').click();">
<form
id="myForm"
action="http://***.***.***.***/***/****/*******="
method="post">
Account name:<br>
<input name="****" value="****" />
<br>
Password:<br>
<input type="password" name="pwd" value="****" />
<br><br>
<input type="submit" value="Login" id="login">
</form>
</body></html>
folks.
I hope you don't see this as a silly question because i am new to JavaScript. I did my research on how to solve this problem but the answers i found on stack overflow were kind of too high for me right now. And i don't like to copy codes either. I want to learn it. My JavaScript code worked on one field but didn't work for all fields even when i did a loop.
Please you are free to show me how to do this professionally. I would be grateful to see many approaches or methods. Gracias
function Validate(x){
var required = document.getElementsByClassName("required");
for(var x = 0; x > required.length; x++){
if ((required[x].value == "") || (required[x].value == null)) {
required[x].style.backgroundColor = "red";
required[x].style.color = "white";
} else {
required[x].style.backgroundColor = "";
required[x].style.color = "#777";
}
}
}
<form id="form1" name="form1" method="post" action="">
<p>
<label for="textfield">Name</label><br />
<input type="text" name="name" id="name" class="forme required" onblur="Validate(name)" />
<br />
<label for="textfield">Surname</label><br />
<input type="text" name="surname" id="surname" class="forme required" />
<br />
<label for="textfield"> School</label><br />
<input type="text" name="school" id="school" class="forme required" />
<br />
<label for="textfield">Mobile</label><br />
<input type="text" name="mobile" id="mobile" class="forme required" />
<br />
<label for="email"> Email</label><br />
<input type="text" name="email" id="email" class="forme required"/>
</p>
<p>
<input type="reset" name="reset" id="reset" value="Reset" />
<input type="submit" onclick="Validate()" name="submit" id="submit" value="Submit" />
</p>
</form>
Be grateful for ya time.
as mentioned in the comments of your question, you used the wrong sign (">" ist false, "<" is true). But your code has some more failures.
The for attribute on the label elements should always point to the respective input field, so use the ID of the input field.
It's may better to use the JavaScript addEventListener method instead of the DHTML attribute onclick, but that is probably a matter of taste.
document.getElementById("submit").addEventListener("click", function(event){
var req = document.querySelectorAll("form input.required"),
error = false;
for(var i = 0; i < req.length; i++){
if(req[i].value.trim() == ""){
if(!error){
error = true;
}
req[i].style.setProperty("color", "#ffffff");
req[i].style.setProperty("background-color", "#ff0000");
} else {
req[i].style.removeProperty("color");
req[i].style.removeProperty("background-color");
}
}
if(error){
// Prevent Form Submit
event.preventDefault();
}
});
<form id="form1" name="form1" method="post" action="">
<p>
<label for="name">Name</label><br />
<input type="text" id="name" name="name" class="forme required" />
</p>
<p>
<label for="surname">Surame</label><br />
<input type="text" id="surname" name="surname" class="forme required" />
</p>
<p>
<label for="school"> School</label><br />
<input type="text" id="school" name="school" class="forme required" />
</p>
<p>
<label for="mobile">Mobile</label><br />
<input type="tel" id="mobile" name="mobile" class="forme required" />
</p>
<p>
<label for="email"> Email</label><br />
<input type="email" id="email" name="email" class="forme required" />
</p>
<p>
<input type="reset" id="reset" name="reset" value="Reset" />
<input type="submit" id="submit" name="submit" value="Submit" />
</p>
</form>
Please note: Don't use ONLY JavaScript to validate your form fields. You should always check the passed user informations on the server side too, because you can't control the user.
Have fun learning JavaScript.
Sincerely,
Sam.
I have multiple forms in same page with submit , i want to hide the form after form submit and display a link for the respective forms
Below is the html i have the same class name for all the forms
and for the submit class also.
<div id="wpcf7-f63-p1-o1">
<form name="" class="wpcf7-form" action="" method = "post">
<input type="text" name="your-name" value="" size="40" />
<input type="text" name="email" value="" size="40" />
<input type="submit" value="Send" class="but" />
</form>
</div>
<div id="wpcf7-f63-p1-o2">
<form name="" class="" action="" method = "post">
<input type="text" name="your-name" value="" size="40" />
<input type="text" name="email" value="" size="40" />
<input type="submit" value="Send" class="but" />
</form>
</div>
i tried the below code
<script>
jQuery(".wpcf7-form").submit(function()
{
jQuery("^wpcf7-f63-p1-").hide();
});
</script>';
In your example typed:
jQuery("^wpcf7-f63-p1-").hide();
i think should be:
jQuery("#wpcf7-f63-p1-o1").hide();
Use this on form submit
$('input[type="submit"]').click(function() {
$form = $(this).parent();
$('<p>link to form</p>').insertBefore($form);
$form.hide();
});
Are you looking for jquery .find() ?
you could do something like this:
$('form').submit(function(){
$(this).find('.myForm').hide();
$(this).find('.link').show();
}
.link {
display:none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<form name="" class="" action="" method = "post">
<div class="myForm">
<input type="text" name="your-name" value="" size="40" />
<input type="text" name="email" value="" size="40" />
<input type="submit" value="Send" class="but" />
</div>
<a class="link" href="#">Link</a>
</form>
ah error on your jquery selector, change your js to:
jQuery(".wpcf7-form").submit(function()
{
jQuery("[id^='wpcf7-f63-p1-']").hide()
return false;
});
working jsfiddle code
NB. you may need to delete the return false, I added it to see the elements getting disappeared after submit.
I have a page where i am disabling the button after submit for 10 seconds and if validation succeeds form is submitted. However, the form is getting submitted even though validation is returning false.
I tried using
<input type="submit">
instead of image still same issue.
Below is the code:
<html>
<head>
<script>
function enableMe(myBtn) {
myBtn.disabled = false;
}
function doValidation() {
document.getElementById('hidden1').value = 'true';
return false;
}
</script>
</head>
<body>
<form id="loginForm" method="post" action="https://www.mySite.com/authService">
<label for="userid">Username</label><br/>
<input type="text" value="" id="userid" name="userid"/>
<br/>
<label for="password">Password</label>
<br/>
<input type="password" value="" id="password" name="password"/>
<br/>
<br/>
<input type="image" id="submitBtn" src="btn_login.gif"
onsubmit="this.disabled=true; setTimeout(enableMe,10000,this); return doValidation();">
<input type="hidden" id="hidden1" name="hidden1" value="false"/>
</form>
</body>
</html>
Validation should be attached to form, not input element...
<form id="whatever" ... onsubmit="return doValidation();">
