I'm trying to make a simple register/login system but when I press the button for both, it doesn't do what I need it to do.
I put
alert("I work!");
at the beginning of each function supposed to work to see if it actually gets triggered but it doesn't. I also checked if the onclick events for both are referenced correctly and they are. I even tried to copy the actual scripts into the html file to ensure that it's not a reference issue. At this point, I'm really stuck, and if this is some syntax error, it doesn't alert me and I'm not aware of any.
The codes are:
index.html:
<!DOCTYPE html>
<html>
<head>
<title>Opportunities</title>
<script type="text/javascript" src="jquery-3.3.1.min.js"></script>
<script type="text/javascript" src="/js/script.js"></script>
</head>
<body>
<p>Uwu</p>
<form>
<p>Username <input type="text" class="username" /></p>
<p>Password <input type="password" class="password" /></p>
<button onclick="loginUser()">Login</button>
</form>
<p>Not yet registered? Click here to create an account. </p>
</body>
</html>
registration.html:
<!DOCTYPE html>
<html>
<head>
<title>Register</title>
<script type="text/javascript" src="jquery-3.3.1.min.js"></script>
<script type="text/javascript" src=/js/script.js"></script>
</head>
<body>
<p>Registration page</p>
<form>
<p>Username <input type="text" class="username" /></p>
<p>Password <input type="password" class="password" /></p>
<button onclick="registerUser()">Register</button>
<!--onclick event doesn't work-->
</form>
<p>Click here to go back.</p>
</body>
</html>
and script.js:
var url = "http://localhost:8888";
function test(){
console.log('hello');
}
function registerUser(){
alert("I work!");
var username = document.getElementbyClassName("username");
var password = document.getElementbyClassName("password");
$.ajax{(
url: url + "/register",
method: "post",
data: {
username: username[0].value,
password: password[0].value
}
success: function(respons){
alert(response.message);
}
}).error(function(response){
alert(response.message);
});
}
function loginUser(){
alert("I work!");
var username = document.getElementbyClassName("username");
var password = document.getElementbyClassName("password");
$.ajax({
url: url + "/login",
method: "post",
data: {
username: username[0].value,
password: password[0].value
}
}).success(function(response){
alert(response.message);
}).error(function(response){
alert(response.message);
});
}
Whenever I press the buttons for each, it just clears the texts in my inputs but doesn't launch an alert like I intend to. Please do tell me what I should check regarding this. Thank you.
I think your script is not loaded
Remove the frist backslash ('/') from
<script type="text/javascript" src=/js/script.js"></script>
If you are using your browser I would try first that you dont have any "popup" script blocking extensions, I had the same issue and the issue was chrome popup js blocker cause simple adblocker doesnt work for some sites.
cheers
Looks like a typo in the registerUser() function try changing the ajax call to
$.ajax({
url: url + "/register",
method: "post",
data: {
username: username[0].value,
password: password[0].value
},
success: function(respons){
alert(response.message);
}
}).error(function(response){
alert(response.message);
});

I trying to print the data which was entered by the user, and transfer that through ajax and trying to print or echo it with the help of php code, but I could not do that. enter code here
this is my code:
<html>
<head>
<title>
test ajax
</title>
<script src="jquery.js"></script>
</head>
<body>
<h2>test button</h2><br>
<form>
<input type="text" id="a"><br>
<input type="button" id="b" value="display">
</form>
<script>
$(document).ready(function() {
$('#b').click(function() {
let a = $('#a').val();
alert(a);
$.ajax({
type: "POST",
url: "same_file.php",
data: {
c: a
},
success: function() {}
});
});
});
</script>
</body>
</html>
<?php
extract($_POST);
if(isset($_POST["c"])) {
echo $_POST["c"];
}
?>
I think that, I have the problem with the php code. please give me any solution.
Try it like this
This is your Html
<html>
<head>
<title>
test ajax
</title>
<script src = "https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<body>
<h2>test button</h2><br>
<form>
<input type = "text" id = "a" > <br>
<input type = "button" id = "b" value = "display" >
</form>
</body>
</html>
<script>
$(document).ready(function(){
$('#b').click(function() {
let a = $('#a').val();
//alert(a);
$.ajax({
type: "POST",
url: "same_file.php",
data: {c: a},
success: function(response) {
alert(response);
}
});
});
});
</script>
This is your same_file.php
<?php
//extract($_POST); code works even without this
if(isset($_POST["c"])) {
echo $_POST['c'];
}
?>
Not sure if your jquery library call is ok so I called the one on the web instead. Also your success:function() was not doing anything which is why you didn't receive anything.
Also always format your code with some indention so that it can be easier to read and comprehend by others.
You probably want to echo before the body is rendered.
But in true, unless you need to process the data the user sends, you don't need PHP at all.
And in truth, you probably don't need jQuery as well, fetch() works just fine.
$(document).ready(function() {
$('#b').click(function() {
let a = $('#a').val();
alert(a);
$.ajax({
type: "POST",
url: "same_file.php",
data: {
c: a
},
success: function() {}
});
});
});
<?php
if (isset($_POST["c"]))
{
// print/echo user data send from form.
echo $_POST["c"];
// stop the script from rendering the html below.
exit();
}
?>
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>
<h2>test button</h2><br>

<input type="text" id="a"><br>
<input type="button" id="b" value="display">

<!-- add script element with js code here -->

I want a user to fill in a website url and when clicking on the submit button I want a ajax request to fire and show the response on the same page in <div id="test"></div> but when I fill in the input field and click submit nothing shows. But if I check the console I see the ajax page getting requested.
Here is pagespeed.html
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js" integrity="sha256-9/aliU8dGd2tb6OSsuzixeV4y/faTqgFtohetphbbj0=" crossorigin="anonymous"></script>
<form method="post">
<input type="text" id="website" name="website">
<button id="button_1" value="val_1" name="but1">button 1</button>
</form>
<script>
$("button").click(function(e) {
e.preventDefault();
$.ajax({
type: "POST",
url: "/lighthouse.php",
data: {
email: $('#website').val() // < note use of 'this' here
},
success: function(result) {
$('#test').html(data);
},
error: function(result) {
alert('error');
}
});
});
</script>
<div id="test">
</div>
And here is lighthouse.php
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js" integrity="sha256-9/aliU8dGd2tb6OSsuzixeV4y/faTqgFtohetphbbj0=" crossorigin="anonymous"></script>
<script>
$(document).ready(function() {
// INTRODUCTION RIGHT
$("#test").text("Let's get in touch");
});
</script>
So the jQuery function is not showing on the pagespeed.html page because the <div id="test"></div> keeps empty.
Thanks for your time!
You need to change from
$('#test').html(data);
to
$('#test').html(result);
because
I have created a form in which on submitting name my url is getting redirected but i want after form action it should get redirect to my mobile validation page. after putting the code, i want it to show the offer page. I am not able to write ajax. my function is not getting called. here is what i have tried till now
http://plnkr.co/edit/3DA7YGb58BgcVcD0d10f?p=preview
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="style.css">
<script src="script.js"></script>
</head>
<body>
<form name="msform" action="another.html" method="post" id="msform">
<input name="name" type="text" placeholder="First Name" />
<input class="bl" id="submitbl" type="submit" value="Submit" />
</form>
<script type="text/javascript">
$("#submitbl").click(function(){
if($("#msform").valid() === true) {
var name = $('input[name|="name"]').val();
//use ajax to run the check
$.ajax({
type : 'POST',
url : 'mobile.html',
success: function(responseText){
resp = responseText.trim().substring(14);
if(resp == 'qualified') {
url_redirect({url: "offer.html",
method: "post",
data: { "fname": name }
});
}
}
});
}
});
</script>
</body>
</html>
For this you can do something like:
write a jQuery onsubmit function and trigger click event for submit button.
$("#msform").on('submit',function(){
$("#submitbl").trigger('click');
});
Or
submit your form through ajax and in success function redirect to mobile.html
i got a website with some buttons and a camerastream which shows a coffee machine. with php function i'm able to set the machine on/off via TCP/IP messages. Now i would like to send on/off commands over button, without refreshing the website. After reading some similar threads, i recognized that the only way is using AJAX.
After pressing Button the Page doesnt refresh but it seems that something in backround get done. But my "Test" String doesnt get show.
Does anyone know whats wrong with my code?
Thanks in advance!
ajax.php
<?php
if($_POST['action'] == 'call_this') {

You are using the HTML element input with a type set to submit, this means that on click the page assumes you want to be redirected to the handling page URL normally supplied in the Form tag. You can use the javascript method of PreventDefault() or you can change the element from a form submit to a link like this.
<html>
<head>
<script src="jquery-1.12.0.min.js"></script>
<script language="javascript" type="text/javascript" src="buttonClick.js"></script>
</head>
<body>
....
....
SET ON
....
....
</body>
</html>
A link with a javascript href will not try and redirect. Your example left the page before waiting for the php script to return.
Try This, ajax.php :
<?php
if($_POST['action'] == 'call_this') {
echo 'TEST';
}
?>
buttonClick.js :
$(document).ready(function()
{
$("#form1").submit(function (e) {
e.preventDefault();
$.ajax({
type: "POST",
url: 'ajax.php',
data:{action:'call_this'},
success:function(html) {
alert(html);
}
});
})
})
index.php :
<html>
<head>
<script src="jquery-1.12.0.min.js"></script>
<script language="javascript" type="text/javascript" src="buttonClick.js"></script>
</head>
<body>
....
....
<form id="form1">
<input type="submit" name="submit" value="SET ON">
</form>
....

Hi I am very new to JavaScript, looking for some help. I have a form, shown below. When the user gives input and clicks submit, I want to call a php file (shown below also) to be invoked and return a hello. Here is the code I have tried, though it is not working as intended.
<html>
<head>
<script type='text/javascript' src="http://code.jquery.com/jquery-1.8.0.min.js"></script>
</head>
<body>
<form>
<input id="name-typed" type="text" />
<input id="name-submit" type="submit" value="submit" onclick="post()"/>
</form>
<div id="result"></div>
</body>
<script>
function post() {
var hname = $('input#name-typed').val();
$.post('dat.php',{name: hname},function(data) {
$('div#result').html(data);
});
}
</script>
</html>
The PHP file dat.php looks like this:
<?php echo "hello";?>
As in my first paragraph, can anyone suggest any changes I should make?
Try this:
you can change dat.php to say:
<?php
$name = $_POST['name'];
echo "Hello ".$name;
?>
And then your html file would be:
Notice that the button type is changed to a normal button so that it just execute the function rather than submitting the form.
<html>
<head>
<script type='text/javascript' src="http://code.jquery.com/jquery-1.8.0.min.js"></script>
</head>
<body>
<form>
<input id="name-typed" type="text" />
<button type="button" onclick="post()">Submit</button>
</form>
<div id="result"></div>
</body>
<script>
function post() {
$.ajax({
type: "POST",
url: "dat.php",
data: { name: $('#name-typed').val()
},
success: function(response) {
$('#result').html(response);
}
});
}
</script>
</html>
I haven't test but something like this:
$('form').submit(function(){
post()
return false;//block the reload of the page
})
In fact I think you just forget the return false. remvove the onclick if you use my answer
