In a HTML form I am using JavaScript Form validation to avoid empty fields. This is the code for the form:
<form method="post" name="form1" onsubmit="return validateForm()" action="<?php echo $editFormAction; ?>">
<table align="center">
<tr valign="baseline">
<td nowrap align="right">Nickname:</td>
<td>
<input type="text" name="nickname" value="" size="32">
</td>
</tr>
<tr valign="baseline">
<td nowrap align="right">Email:</td>
<td><input type="text" name="email" value="" size="32"></td>
</tr>
<tr valign="baseline">
<td nowrap align="right">Password:</td>
<td><input type="text" name="password" value="" size="32"></td>
</tr>
<tr valign="baseline">
<td nowrap align="right"> </td>
<td><input type="submit" value="Insert record"></td>
</tr>
</table>
<input type="hidden" name="estado" value="0">
<input type="hidden" name="MM_insert" value="form1">
</form>
And this is the JavaScript function:
<script>
function validateForm()
{
var x=document.forms["form1"]["nickname"].value;
if (x==null || x=="")
{
alert("First name must be filled out");
return false;
}
}
</script>
As expected, if the user clicks on the submit button and the field 'nickname' is empty, the Alert Dialog is shown, but after closing it, the form is submitted. I am using Dreamweaver as editor and JQuery Mobile in my web, may be this is the problem.
Any help is welcome.

JavaScript:
$(document).on('submit', '#form1', function(){
var x=document.forms["form1"]["nickname"].value;
if (x==null || x=="") {
alert("First name must be filled out");
return false;
} else {
return true;
}
});
Changes:
jQuery Mobile has its own way of form handling, you need to disable it if you want to have classic form handling. It is done via attribute data-ajax="false".
Never use inline javascript with jQuery Mobile, I mean NEVER.
For me this is working fine :
<script>
function validateForm()
{
var x=document.forms["form1"]["nickname"].value;
if (x==null || x=="")
{
alert("First name must be filled out");
return false;
}else{
return true;
}
}
</script>
Just added a else statement. It's working fine for me.
I think your code should work. But If not you can make some changes as
Change 1 Remove Submit event from tag
<form method="post" name="form1" action="<?php echo $editFormAction; ?>">
Change 2.
Change submit button to default button and validate event here
<input type="button" onclick="javascript:validateForm();" value="Insert record">
Change 3.
Now change in javascript Add code form sub
<script>
function validateForm()
{
var x=document.forms["form1"]["nickname"].value;
if (x==null || x=="")
{
alert("First name must be filled out");
}else{
document.forms["form1"].submit();
}
}
</script>

I cant get any of the buttons using onclick to recognise the functions. I get an error "cant find variable". Im very new to all this and at a loss. It doesn't matter which button I click I have the same issues with all of them.
in the below code,
I click on <button onclick="show_admin()">Admin</button> which should call function show_admin().. What am I doing wrong please.

I have tried rearranging the function and moving its position. with no luck
Unless you have JSX installed, You can't just stick HTML elements into JavaScript like that. You will need to use quotes around all the HTML.
It looks like you're reusing the same tags anyway, why not stick all those tags into the HTML portion and update the values in Javascript? You can also update the CSS through JavaScript and set display:none if you want to hide an unused element.
I added the below to the html section
<div class="split right">
<div class="centered" id="showdata">
<form id="adminForm">
<table>
<tr>
<td> User Name </td>
<td>
<input type="String" name="UserName" placeholder="%s">
</td>
</tr>
<tr>
<td> Password </td>
<td>
<input type="String" name="UserPass" placeholder="%s">
</td>
</tr>
</table>
<input type="submit" value="Update Admin Details">
</form>
and the following to the script section
function admin(){
document.getElementById("wifiForm").style.display="none";
document.getElementById("tagForm").style.display="none";
document.getElementById("adminForm").style.display="block";
}
Im using a form to be able to use the input of the user to save some information.
In this case it's instructions for a receipt. However I would like to have an unlimited number of fields for that (as you can see in the image it has 3 fields).
I would like to have an option at the bottom, like a button where it would create a new input field. I've searched in bootstrap documentation and I don't find anything related to that, they always use a fixed number of input fields...
Any suggestion?
This is the code I'm using to generate the fields (10 at the moment):
<div class="col-md-4">
<h2>Instructions</h2>
<div class="form-group">
<table style="width:75%">
<tr>
<th><label asp-for="Instructions[0].Designation" class="control-label"></label></th>
</tr>
#for (int i = 0; i < 10; i++)
{
<tr>
<td><input asp-for="Instructions[i].Designation" class="form-control" placeholder="Step #(i+1) " /></td>
</tr>
<span asp-validation-for="Instructions[i].Designation" class="text-danger"></span>
}
</table>
</div>
The following code is a fully functional example on how you can achive what you are asking for:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Instructions</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
</head>
<body>
<div class="col-md-4">
<h2>Instructions</h2>
<div class="form-group">
<table id="instructionsTable" style="width:75%">
<tr>
<th><label asp-for="Instructions[0].Designation" class="control-label"></label></th>
</tr>
<tr>
<td><input asp-for="Instructions[i].Designation" class="form-control" placeholder="Step #(i+1)" /></td>
</tr>
<span asp-validation-for="Instructions[i].Designation" class="text-danger"></span>
</table>
</div>
<input id="addInputBtn" type="button" value="+" />
<script>
$(document).ready(function(){
$("#addInputBtn").click(function(){
var newInput = "<tr><td><input asp-for='Instructions[i].Designation' class='form-control' placeholder='' /></td></tr>";
$("#instructionsTable").append(newInput);
})
});
</script>

I am trying to create a simple login page for a server:
<html>
<head>
<title>Login Page</title>
</head>
<body>
<form name="loginForm" method="post" action="login.php">
<table>
<tr>
<td colspan=2><center><font size=4><b>HTML Login Page</b></font>
</center></td>
</tr>
<tr>
<td>Username:</td>
<td><input type="text" size=25 name="userid"></td>
</tr>
<tr>
<td>Password:</td>
<td><input type="Password" size=25 name="pwd"></td>
</tr>
<tr>
<td ><input type="Reset"></td>
<td><input type="submit" onclick="return check(this.form); load();"
value="Login">
</td>
</tr>
</table>
</form>
<script language="javascript">
function check(form)
{
if(form.userid.value == "n" && form.pwd.value == "n")
{
return true;
}
else
{
alert("Error Password or Username")
return false;
}
</script>
</body>
</html>
The HTML above is how i would like the page to look, however i want to add another function that when the login button is pressed i would like the page to take me to a different page like google for example.
Is there anyway I can do this?
Through Html you can do something like:
<form action="http://google.com">
<input type="submit" value="Go to Google">
</form>

I need my control flow as Click radio->click details button->Pop up with radio button details message. Please help me !
First you dont have any form submit action means you dint submit the form anywhere is the reason you dint get any value from post.If you dont want to reload page you can use jquery to set the value of popup.
Fiddle
Second to place required field in radio button just put required in only one radio button.Source
Do this
<form id="myform">
<p>
Untraced :<input type="radio" name="inc_untraced" value="No" required />No
<input type="radio" name="inc_untraced" value="Yes" />Yes
</p>
<input type="submit" name="details" value="Details" id="my-button" />
</form>
<!-- Element to pop up -->
<div id="element_to_pop_up">
<a class="b-close">x<a/>
U have clicked on <?php $_POST['inc_untraced'];?>
</div>
Fiddle
(function($) {
$(function() {
// Binding a click event
// From jQuery v.1.7.0 use .on() instead of .bind()
$('#my-button').bind('click', function(e) {
// Prevents the default action to be triggered.
e.preventDefault();
if($('input:radio:checked')){
var v = $('input:radio:checked').val();
if(v!=undefined){
$('.radioVal').text(v)
}else{
alert('please select radio button')
return false;
};
}
// Triggering bPopup when click event is fired
$('#element_to_pop_up').bPopup();
});
});
})(jQuery);
<p>
Untraced :<input type="radio" name="inc_untraced" value="No" required />No
<input type="radio" name="inc_untraced" value="Yes" required />Yes

Hi all i have login form design in html 5 and depending on login details enterd it shoud redirect to respective page. i am checking login details in javascript and redirecting page using javascript but its not working at all. page is not getting redirect.
<form id="html5form" method="post">
<table border="0" cellpadding="0" cellspacing="0" width="100%" class="tbl_form">
<tbody>
<tr>
<td>
<label>Username: <span>*</span></label>
</td>
<td>
<input type="text" name="txtLoginNm" id="txtLoginNm" class="field" required="required" placeholder="Enter Username" onkeydown="fnAdmPassword(e);"/>
</td>
</tr>
<tr>
<td>
<label>Password: <span>*</span></label>
</td>
<td>
<input type="password" name="txtPwd" id="txtPwd" maxlength="20" class="field" required="required" Placeholder="Enter Password" onkeydown="fnAdmPassword(e);"/>
</td>
</tr>
<tr>
<td>
</td>
<td>
<input type="submit" title="Login" value="Login" name="Login" class="buttom" onclick="javascript:return fnlogin();" />
</td>
</tr>
</tbody>
</table>
</form>
//// and the javascript function is as follows
function fnlogin()
{
if ((document.getElementById("txtLoginNm").value == "") && (document.getElementById("txtPwd").value == ""))
{
alert("Please enter Username & Password!");
}
else if ((document.getElementById("txtLoginNm").value == "user155") && (document.getElementById("txtPwd").value == "user155"))
{
window.location.href = "comp-admin/u_dashboard.shtm";
}
else if ((document.getElementById("txtLoginNm").value == "superadmin") && (document.getElementById("txtPwd").value == "superadmin")) {
window.location.href = "s-admin/edit-profile.shtm";
}
else (alert("Invalid username or password!"))
}
please tell me why page is not getting redirect
This is why it is not redirecting
<input type="submit" title="Login" value="Login" name="Login" class="buttom" onclick="javascript:return fnlogin();" />
You have to make 2 changes here
Change button type from submit to just button, because then submit functionality is taking precedence and you have no action url defined
Remove javascript: from your call. (As also suggested by Jan Hančič in comments)
So try this
<input type="button" title="Login" value="Login" name="Login" class="buttom" onclick="return fnlogin();" />
