I want my form to load webpages. I want to turn html textbox into address bar. Just like whenever I write URL into that, It loads webpages in the same window.
My current HTML code is:
<html>
<body>
<title>BlogSoc Browser</title>
<h1 style="font-family:verdana;font-size:50px;color:#000000;text-align:center;">Address Bar</h1>
<center><form method="GET" action="/load.php"><input type="text" name="url" value="http://" /><input type="submit" value="Go" name="submit" /></form></center>
</body>
</html>
It looks like this: (couldn't post image)
or you can just open http://blogsoc.org/load
Please tell me the appropriate load.php code. Thanks in advance.
<?php
header("Location: " . $_GET['url']);
?>
should be what you need.
Using client side scripting:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('#myform').submit(function(){ //when form is submitted..
window.location = $('#url').val(); //..get url from the textbox and load that url
return false; // prevent the form from being submitted
});
});
</script>
</head>
<body>
<form id="myform">
<input type="text" id="url" value="http://" />
<input type="submit" id="submit" value="Submit" />
</form>
</body>
</html>
I used jQuery. For reference: https://developer.mozilla.org/en-US/docs/DOM/window.location

I have two functions that need to work when a button is pressed, but (I think)the problem is one is jQuery and the other is PHP (I can't change that part). This is what my code looks like:
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>
$(document).ready(function() {
$("#clicker").click(function(){
alert ("Button Was Clicked!");
});
});
</script>
</head>
<body>
<form name="myForm" action = "page_name.php">
<input id="clicker" type="submit" name="submit" value="Submit" />
</form>
<?php
$msg = "Not Clicked!";
if(isset($_POST['submit']))
{
$msg = "Clicked!";
}
?>
<p> <?php echo $msg; ?> </p>
</body>
</html>
For some reason, the PHP is not working, but the jQuery is. Could someone tell me what I need to change and why?
Thanks!
Use form to submit POST request.
Just change this:
<input id="clicker" type="submit" name="submit" value="Submit" />
with
<form action="" method="POST">
<button id="clicker" type="submit" name="submit">Submit</button>
</form>
Put this under your jquery script
$("#clicker").click(function(e){
e.preventDefault() ; alert ("Button Was Clicked!");
I test my first AJAX form, but when I submit my form the alert message just shows '2'. I search for sending ajax data to the same page and I found, that I can do that, but URL is optional.
my PHP code:
<html>
<body>
<form action="index.php" method="post">
<input name="name" type="text" />
<input type="submit" value="submit" name="submit">
</form>
<?php
if(isset($_POST["name"]))
{
$data="test string";
echo json_encode($data);
}
?>
<script src="jquery-2.1.0.min.js"></script>
<script src="ajax.js"></script>
</body>
</html>
my AJAX code:
$(document).ready(function() {
$('form').submit(function(event) {
$.ajax({
type : 'POST',
url : 'index.php',
data : $(this).serialize(),
dataType : 'json',
encode : true
})
.done(function(data) {
alert(1);
})
.fail(function(data) {
alert(2);
});
event.preventDefault();
});
});
I don't know where I go wrong?
It's better to delegate page generation and json-response generation to different pages. At least you should isolate it, because the following part of page also ends up in ajax-response:
<html>
<body>
<form action="index.php" method="post">
<input name="name" type="text" />
<input type="submit" value="submit" name="submit">
</form>
...
<script src="jquery-2.1.0.min.js"></script>
<script src="ajax.js"></script>
</body>
</html>
Modifiyng your script, you can do something like that:
<?
if(isset($_POST["name"]))
{
// And don't forget to specify content type!
header("Content-type: application/json");
$data="test string";
echo json_encode($data);
} else {
?>
<html>
<body>
<form action="index.php" method="post">
<input name="name" type="text" />
<input type="submit" value="submit" name="submit">
</form>
<script src="jquery-2.1.0.min.js"></script>
<script src="ajax.js"></script>
</body>
</html>
<? } ?>
And, for future, please, post the exact request and response information in your questions, which you can get on Network page for developer tools of chrome, for example.
I'm starting to study web development and as exercise I was trying to make a form for redirecting in HTML with javascript and PHP.
HTML
<html>
<head>
<title>FORM</title>
</head>
<body>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
<script src="script.js" type="text/javascript"></script>
<form>
<input type="text" name="url"><br>
<input class="btn" type="button" id="send" value="Send" />
</form>
</body>
</html>
JavaScript
$(document).ready(function() {
$("#send").click(function(){
var url = $("#url").val();
$.ajax({
type: "POST",
url: "engine.php",
data: "url=" + url,
dataType: "html"
});
PHP
<?php
session_start();
$url = $_POST['url'];
header("Location: /".$url.");
session_destroy();
exit;
?>
The main problem is that seems that the js isn't read. Futhermore I don't know if the PHP is correct. What's wrong?
There's no need to make an AJAX request if you want to redirect to another URL. Also, the way your doing it at the moment wouldn't redirect anyway.
Below, when your click function fires, it will get the URL from your input field, and re-direct to that page.
<html>
<head>
<title>FORM</title>
</head>
<body>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#form_name").submit(function(event){
event.preventDefault();
var url = $("#url").val();
document.location.href = url;
});
})
</script>
<form id="form_name" name="form_name">
<input type="text" name="url" id="url"><br>
<input class="btn" type="submit" id="send" value="Send" />
</form>
</body>
</html>
you need to add id to input
<input type="text" name="url" id="url"><br>
and also header() don't work in ajax
you need to use javascript for redirect
in php
<?php
session_start();
$url = $_POST['url'];
echo '<script>document.location.href = '.$url.'</script>';
session_destroy();
exit;
?>
and put echo text into document with ajax respond function
also you can use a better way ( with out Ajax and submit form )
$(document).ready(function() {
$("#send").click(function(){
var url = $("#url").val();
window.location.href = url;
});
here is the best answer for you How to redirect to another webpage in JavaScript/jQuery?
UPDATE:
also you need delete , tags, here the html code instead of ...
<input type="text" name="url" id="url"><br>
<input class="btn" type="submit" id="send" value="Send" />
So you think your javascript isn't being executed? Does that mean you've debugged this?
If none of your javascript runs - including your ready handler, then the server isn't finding the js files. If some of your javascript is running it's possible that an error is causing it to stop. You probably just need to do a little debugging.
I want to make a url search input for an iframe with HTML (and maybe JS).
I searched in alot of site and I didn't found.
Does anyone know how?
I think I'll need to use something like
<form action="http://" method="get" target="myiframe">
<input id="search" type="text">
</form>
?
You can use jQuery:
// Send search form data
$("#searchFormId").submit(function(event) {
// stop form from submitting normally
event.preventDefault();
// get search form input field value
var s = $('#inpuFieldId').val();
// update iframe url
$('#iframeid').attr('src', 'http://example.com?formvalue='+s);
}
);
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<title>Update iframe</title>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
</head>
<body id='body'>
<div><form action="" method="get" id="myform"> <input id="search" type="text" /><input type="submit" value="go" /> </form></div>
<div align="center"><iframe name="MyIframe" id="myiframe" src="" width="980" height="500" scrolling="yes" frameborder="0"></iframe><div>
<script>
// Send search form data
$("#myform").submit(function(event) {
// stop form from submitting normally
event.preventDefault();
// get search form input field value
var s = $('#search').val();
// update iframe url
$('#myiframe').attr('src', 'http://jquery.com/?s='+s);
}
);
</script>
</body>

Where is the wrong in form thanks.
A few things are wrong here:
You have an onclick on a hidden form element
The Post! anchor onclick isn't submitting anything
Suggested changes:
<head>
<script type="text/javascript" src="prototype.js"></script>
<script>
function showResponse(req){
$('show').innerHTML = req.responseText;
}
</script>
</head>
<body>
<form id="test" name="test" action="test.php">
<input type="hidden" name="name" id="name" value="cats" />
<input type="hidden" name="somethingElse" value="test" />
</form>
Post!
<div id="show"></div>
</body>
form id="test" and no name
and yet :
a href="#" onclick="myForm.submit()"
just for starters.
