I have a php page, wich hase some external links to js files in the head, and on body I have some selectable elements from jquery(sometimes I do not have them, because thouse elements are generated if the user is login). The problem is in the javascript I wrote, I get this error: TypeError: Object [object Object] has no method 'disableSelection'. Even if I put a ".sortable" element in the php, I still get this error. In html looks like it has no problem with that and works fine. The code that gives me the error is this:
Sorry for my english. I can put the hole code if you want but is too big. I think the problem is because the javascript is loading too fast or before of the html is generated.( I tried to put a variable in the js and that function under a if() but is not working)
The javascipt(scripturi.js):
var logat=0;
$(document).ready(function() {
$( ".sortable0" ).sortable();
$( ".sortable0" ).disableSelection();
$( ".sortableIt" ).disableSelection();
$( ".sortableIt" ).sortable(
{
stop: function(event, ui)
{
for(var i=0;i<ui.item.parent().children().length;i++)
{
var x =ui.item.parent().children()[i].id;
//update items din acest sertar
//updateItemServer(x,i)
//alert(x+ " " + i);
}
}
});
$( ".sortable" ).disableSelection();
$( ".sortable" ).sortable({ stop: function(event, ui) {reparaZindex();}});
});
function updateItemServer(x,i){
//alert(x+" "+i);
}
function incarca(){
$(document).ready(function (){
$.getJSON("http://students.info.uaic.ro/~calin.chifan/api/compartiment/list.json", function(data){
var html = [];
/* loop through array */
$.each(data, function(index, d){
addCompartiment(d.nume_comp,d.id);
});
}).error(function(jqXHR, textStatus, errorThrown){ /* assign handler */
alert("error occurred!");
});
});
}
function addCompartiment(nume,id){
$("#sortable0").append('<ul class="sortable" id'+ +'>');
}
function updateIndexServer(x,y){
//alert(x+" "+y);
//trimite id-ul x si pozitia y
}
function reparaZindex(){
$.each($(".sortable > li"), function()
{
if($(this).find('.sertar')[0])
{
$(this).find('.sertar').eq(0).css('z-index',(500-$(this).index()*2));
updateIndexServer($(this).find('.sertar')[0].id,$(this).index())
}
if($(this).find('.sortableIt')[0])
$(this).find('.sortableIt').eq(0).css('z-index',(501-2*$(this).index()));
});
}
window.onload = function() {
//incarca();
//reparaZindex();
}
It's strange that in the html I don't have this problem. After the user is logedin I want to call a function that will append some ul (.selectable) elements but so far it can't even notice that there are some elements. If you want I can give you a link to the page I work.
A little bit of the php:
<?php
ini_set('session.save_path', '/tmp/');
session_start();
$logged=0;
if(isset($_SESSION['autentificat']))
{
if($_SESSION['autentificat']==1)
$logged=1;
}
$user= $_COOKIE['user'];
echo'

You need to place the jQuery code in the $(document).ready(); function and then it will run only when the page loads like so:
$(document).ready(function() {
// your code here
});
This will make sure it only runs when the page and all the DOM elements have completely loaded.
UPDATE:
Can you add the following code in your HTML head section as you need jQuery UI to make the relevant method call:
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script>
Make sure you include it after you have loaded jQuery, so the head section code should be like:
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script>
<script src="login.js"></script>
<script src="scripturi.js"></script>
<script src="dulap.js"></script>
<script src="login.js"></script>
First thing is to make sure you have jQueryUI loaded since the method you are calling belongs to its API. We can take things forward from there!
Your code does not include jquery ui anywhere! You just include JQuery, not the JQuery UI part. The Sortable is part of the jquery ui. Check it out at: http://jqueryui.com/sortable/ If you include it correctly it is not problem if you have a element on your page which responds to the selector or not. Just make sure, that you include the correct library.
You need to add jQueryUI. Please add below code to after jquery section.
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script>

Hello so I have 2 submit buttons with different names (btn1, btn2) in my html form and what I am trying to do is to submit to another page without refreshing page. So what I wanted to do is if I click btn1 submit it will do something and if I click btn2 it will do another thing. My code in the html page is this
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Percentage</title>
<script type="text/javascript" src="jquery.js"></script>
<script>
$(document).ready(function(){
$('#myForm').on('submit',function(e) {
$.ajax({
url:'update.php',
data:$(this).serialize(),
type:'POST',
success:function(data){
console.log(data);
$("#success").show().fadeOut(5000);
},
error:function(data){
$("#error").show().fadeOut(5000); //===Show Error Message====
}
});
e.preventDefault();
});
});
</script>
</head>
<body>
<form method="POST" id="myForm">
Input Amount: <input type="text" name="txt_amount" required placeholder="Input number"> <br /> <br />
<span id="error" style="display:none; color:#F00">Some Error!Please Fill form Properly </span> <span id="success" style="display:none; color:#0C0">All the records are submitted!</span>
<input type="submit" name="btn1"> <input type="submit" name="btn2">
</form>
</body>
</html>
And the code in my update.php page
<?php
if(isset($_POST['btn1'])) {
//insert query
} else if(isset($_POST['btn2'])) {
//another insert query
}
?>
I actually got it working if I only have 1 submit button and no if(isset()) thing in the update.php page. What can I do to use 2 submits and with issets in another page without refreshing the main page?
$(this).serialize();
The above code statement doesn't include name of the submit button as a key value pair.
So, as people have suggested before me, you should use button instead of submit button. Something like this.
HTML and JS
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Percentage</title>
<script type="text/javascript" src="jquery.js"></script>
<script>
$(document).ready(function(){
$('#btn1, #btn2').on('click',function(e) {
var datastr = $(this).serialize() + "&button_id="+$(this).attr('id');
$.ajax({
url:'update.php',
data:datastr,
type:'POST',
success:function(data){
console.log(data);
$("#success").show().fadeOut(5000);
},
error:function(data){
$("#error").show().fadeOut(5000); //===Show Error Message====
}
});
e.preventDefault();
});
});
</script>
</head>
<body>
<form method="POST" id="myForm" action="update.php">
Input Amount: <input type="text" name="txt_amount" required placeholder="Input number"> <br /> <br />
<span id="error" style="display:none; color:#F00">Some Error!Please Fill form Properly </span> <span id="success" style="display:none; color:#0C0">All the records are submitted!</span>
<button id="btn1">Button1</button><button id="btn2">Button2</button>
</form>
</body>
</html>
AND PHP would be:
<?php
if($_POST['button_id'] == 'btn1') {
//do something
} else if($_POST['button_id'] == 'btn2') {
//do something else;
}
?>
Use this, may useful for you
try
$('#myForm').on('submit',function(e) {
e.preventDefault();
});
OR
<button type="button">
Use on click event on the button and add the value attribute to the submit button, the value of the click button will be pased to the php file
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Percentage</title>
<script type="text/javascript" src="jquery.js"></script>
<script>
$(document).ready(function(){
$('input[type="submit"]').on('click',function(e) {
e.preventDefault();
$.ajax({
url:'update.php',
data:{'txt_amount':$('input[name="txt_amount"]').val(),'btn': $('input[type="submit"]').val()}
type:'POST',
success:function(data){
console.log(data);
$("#success").show().fadeOut(5000);
},
error:function(data){
$("#error").show().fadeOut(5000); //===Show Error Message====
}
});
});
</script>
</head>
<body>
<form method="POST" id="myForm">
Input Amount: <input type="text" name="txt_amount" required placeholder="Input number"> <br /> <br />
<span id="error" style="display:none; color:#F00">Some Error!Please Fill form Properly </span> <span id="success" style="display:none; color:#0C0">All the records are submitted!</span>
<input type="submit" name="btn1" value="btn1"> <input type="submit" name="btn2" value="btn2">
</form>
</body>
</html>
php:
<?php
if($_POST['btn'] == 'btn1') {
//do something
} else if($_POST['btn'] == 'btn2') {
//do something else;
}
?>
Can somebody please explain why this code does not allow my imploded variable separated by commas does not work when I surround it in a table or many div format.
The code works when I remove it from within the table. I also tested it with elements of the form within other divs and that failed to. It only works when its a HTML form on its own.
Summary: I want engineers output like. john,derek,peter et al.... At the moment it only gives my the top line
<?php
$eng = array();
$test = $_POST['test'];
$eng = implode(',',$_POST['engineers']);

//Append a new row of code to the "#items" div
$("#items").append('<div><input type="text" name="engineers[]"><button class="delete">Delete</button></div>');
});
$("body").on("click", ".delete", function (e) {
$(this).parent("div").remove();

});
</script>
</head>

<?php echo $eng; ?>

One thing to point out is that always process form input when the form is submitted.
And your markup is a little bit wrong, its the other way around. The table must be inside the form.
<?php
// handle form inputs when the form is submitted
if($_SERVER['REQUEST_METHOD'] == 'POST') {
$eng = implode(',', array_filter($_POST['engineers']));
echo $eng;
}
?>
<div class="form_table">
<!-- form must wrap the table -->
<form method="POST">
<table>
<tr>
<th><label for="engineers">Engineers</label></th>
<td>
<button type="button" id="add">Add Another Engineer</button>
<div id="items">
<div><input type="text" name="engineers[]" /></div>
</div>
</td>
</tr>
<tr>
<th colspan="2">
<input type="submit" name="" value="Add Job" class="submit" />
</th>
</tr>
</table>
</form>
</div>
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.0/jquery-ui.js"></script>
<script>
$(document).ready(function(){
//when the Add Filed button is clicked
$("#add").click(function (e) {
//Append a new row of code to the "#items" div
$("#items").append('<div><input type="text" name="engineers[]"> <button class="delete">Delete</button></div>');
});
$("body").on("click", ".delete", function (e) {
$(this).parent("div").remove();
});
});
</script>
Sample Output
put your form outside the table becase table tag can include tr tags not form tag
Ex:
<?php
$eng = array();
$test = $_POST['test'];
$eng = implode(',',$_POST['engineers']);
?>
<html>
<head>
<script src="//code.jquery.com/jquery-1.10.2.js"></script>

//Append a new row of code to the "#items" div
$("#items").append('<div><input type="text" name="engineers[]">
<button class="delete">Delete</button></div>');
});
$("body").on("click", ".delete", function (e) {
$(this).parent("div").remove();
});
});
</script>
</head>
<body><?php
echo $eng;
?>

<?php`enter code here`

Thanks
You're pretty much not posting anything from here:
jQuery(document).ready(function(){
jQuery("#subt").click(function(){
jQuery("#divload").show();
jQuery.ajax({url:"adp.php", type:"post", success:function(result){
jQuery("#disp").html(result);
jQuery("#divload").hide();
}});
return false;
});
});
So I would assume that you only want to generate a text field dynamically. And you can do it without the use of ajax:
var form = $('#FrmMain');
$('<input>').attr({'type' : 'text', 'id' : 'tt', 'name' : 'tt'}).appendTo(form);
Plus you're also trying to print out $_GET['tt'] while the form method is POST
if (isset($_POST['subtest']))
{
print $_GET['tt'];
}
This should also be:
echo $_POST['tt'];
I wanted to show textbox content without refreshing,so I used Jquery
I have problem with this part: name:form.name.value what does this exactly do?And why I have problem?when entering it will show nothing
<html>
<head>
<script type="text/javascript" src="./jquery.js"></script>
<script type="text/javascript">
function get(){
$.post('msql.php',{name:form.name.value},
function(output){
$('#mydiv').html(output).show();
}
);
}
</script>
</head>
<body>
<form name="name">
<input type="text" name="name">
<input type="button" name="but" value="Check" onclick="get();">
<div name="mydiv"></div>
</form>
</body>
</html>
msql.php:
<?php
echo $_POST['name'];
?>
try this:
$(document).ready(function() {
$('input[name="but"]').click(function() {
alert("start");
$name = $('input[name="name"]').val();
$.post('msql.php', {
name: $name
}, function(output) {
alert(output);
$('#mydiv').html(output).show();
});
return false;
});
})
html:
<form id="form_name">
<input type="text" name="name">
<input type="button" name="but" value="Check">
</form>
<div id="mydiv"></div>
I think your problem lies in the period (.) just after html.
it should be $('#mydiv').html(output);
Also, you'll be better off using mgraph's solution but remove the period I just told you about.
I don't think jquery understand what form.name.value is unless you provide it with a proper selector like mgraph suggested.
