jQuery plugin for submiting Forms - javascript

I have a Form like this in asp Classic ..
<form method="post" name="AddItemForm" id="AddItemForm" action="/files/includes/CartControl.asp" style="display:inline;">
// bunch of Hidden Fields.
Then a SUBMIT button.
action of the form takes all the hidden fields and then after processing them redirects user to a CART page.
now what I want to do is....I want user to click on ADD TO CART button, however I want user to stay on the product page while form submits to a new window (not a javascript new window...something like lightbox/colorbox/fancybox DIV etc).
I looked into many jQuery plugins but could not get a satisfied answer...which plugin is BEST for my case? any simple example?
basicly I want to submit to a new overlay div and within that DIV redirect user to a new page to show Product Info.
Thanks

It seems that you are looking for some functionality for asynchronous form submission. There is this jQuery AJAX Form plugin that provides AJAX functionality for forms. You will have something like:
$('#AddItemForm').submit( function() {
// Submit asynchronously
$( this ).ajaxSubmit( function() {
// Form processing is done
// Redirect to the shopping cart page
});
// Show a modal or a fancy "please wait" message
// Prevent default submission
return false;
});

You can find some info in this answer, the code from one of the answers:
$('input#submitButton').click( function() {
$.post( 'some-url', $('form#myForm').serialize(), function(data) {
... do something with response from server
},
'json' // I expect a JSON response
);
});
In "do something with response" you can take the data or url and load it into an overlay div.
If it's a URL, you can use jquery .load :
$('#result').load('ajax/test.html');
If it's html (or data which you wrap in html), just do
$('#result').html(theHTML)

the simplest way (in my view) is to add target attribute to the form which will open new window while the current page won't chage...

form within AJAX jQuery toggle, submits at parent onClick not from submit button

Basically mysimplewebform.php form submits when the toggle is clicked, as opposed to after the form is loaded, used by user and SUBMITTED via submit button at form. Obviously I need to have form operate functionally; user fills it out, and clicks submit. I simply used AJAX to bring in the form on the template page. Now everytime toggle button is clicked 'Form is submitted with empty values' and then appears in the toggle. Making it pretty useless at this point, I have been struggling with this forever. I think this is a matter of toggling the data: below --
$(document).ready(function() {
$('#toggle3').click(function(){
var tog = $('.toggle');
$.ajax({
type: 'POST',
url: '/mysimplewebform.php',
data: $(this).closest('form').serialize(), // This was a recent suggestion
success: function (fields){
tog.html(fields);
tog.slideToggle(1000);
}
});
});
});
Branched out from: How to send external form POST data through AJAX
Ok, so you want to display an html form when a user clicks a button? In that case you can use the simplified jquery load method:
$('#yourbutton').click(function(){
$('#somediv').load('/mysimplewebform.php');
});
I know this doesnt handle your toggle requirement, but i dont think that is where you are having issues.
Now onto the php. I dont know exactly what should be in mysimplewebform so heres an example
if(isset($_POST['fname'])){
//we have a post request, lets process it
echo 'hello'.$_POST['fname'];
}?>
<form action="absolute/path/to/mysimplewebform.php" method="post" id="mysimplewebform">
<input type="text" name="fname" placeholder="Enter Name">
<input type="submit" value="submit">
</form>
Notice the action is an absolute path to the file, because a relative path will be wrong if the form is loaded into another page via ajax.
Now when this form is submitted, the browser will be redirected to mysimplewebform.php.
I expect you want to stay on the same page, in which case you could submit the form via ajax:
$('#mysimplewebform').submit(function(ev){
ev.preventDefault();//stop normal redirecting submit
$.post( $(this).attr('action'), $(this).serialize(), function(data){
$('#somediv').html(data)
});
This replaces the whole form in the dom with the output, so the hello message would be displayed.
All of the above is an attempt to help you understand where you have been going wrong in your attempts. It is not the best solution to your overall problem - i would separate the html form and processing into seperate files for a start, but it should be familiar to you.

jQuery alert after form submit and redirect

I am trying to invoke an alert box after a form is fully submitted AND the page is redirected, but don't exactly know how to go about it.
After a user registers with the site, it redirects them to their profile page.
What I want to do is, IF the request came from the from with ID of new_user, AND after the user gets redirected to their profile page, invoke an alert.
So on the profile page, after coming from the new_user form, invoke an alert.
Right now I am doing this:
$('form#new_user').submit(function(e) {
e.preventDefault(); // don't submit multiple times
this.submit(); // use the native submit method of the form element
alert("Testing page load.");
});
But that invokes the pop up after the form is submitted, before the user gets to the profile page.
How can I accomplish this?
Thanks.
hi i think you can do this easily using AJAX
pass the variables to the ajax page and on SUCCESS show the alert box which you want to show.
i think it is better to use AJAX to Jquery for your scenario.
Here's an idea on how you could do it:
#inside your RegistrationsController
def create
user = User.new(user_params)
if user.save
redirect_to user_profile_path(user, from: 'registration), notice: "Successful registration."
else
# code for handling error in registration
end
end
Now that you have a param :from passed to the user_profile_path every time a user is just registered, you can do something like this in your JS for your profile page
if(window.location.search == 'from=registration') {
alert("Redirected from registration!");
}
Let me know if that works.
Where you need this alert message? in your registration page or profile page?
If you want to invoke alert in your registration page, better you should us ajax post method for submitting the form.
If you want to display alert message in your profile page, pass a value as query string and write jquery alert function based on that query string value.

Submit Form in DNN, typical answer not working

I am trying to submit a mailchimp form from within my DNN (DotNetNuke) site. Typically, you just remove the form tags and put some javascript in the onclick event of the submit button...like here. This works and you can see as such here.
But, I am using this popup module, as I want this form to pop up when someone comes to the site. And in this configuration it does not work. It will submit the form to the designated URL, but no form data is passed. This page is here.
A couple of observations:
When you view the page source, the popup form is within the form tags, yet a this.form returns null in the script.
When you inspect the submit button element in Chrome, you see that the html form is then OUTSIDE the form tags.
So maybe there is some javascript with this popup module that is moving the DOM element on page load???
I created a js function to call on the input button submit; code is as follows:
function submitSubscription(clickedElement){
$form = $('body').find('form');
$form.attr('action', 'http://InciteResults.us2.list-manage1.com/subscribe/post?u=6d82b6a028c94cc75005eb4fe&id=1c7ceabac4');
$form.submit();
}
Note: in this function clickedElement.form is returning null.
Because your content is not in a <form>, you're going to put it inside a <form> in order for your script to work. You can either dynamically create a <form> element, or move your content back inside the main <form> when you submit. Try something like this:
function submitSubscription(clickedElement){
var $form = $('<form></form>', { action: 'http://InciteResults.us2.list-manage1.com/subscribe/post?u=6d82b6a028c94cc75005eb4fe&id=1c7ceabac4' });
$('#mc_embed_signup').wrap($form);
$form.submit();
}

How do I re-bind this Javascript event, using jQuery, after an XHR response?

I have a form embedded in a web page. When the user clicks submit the XHR response is either a form with all fields reset (i.e. upon success), or a form with error messages (i.e. upon failure). I use the response to overwrite the existing form.
This works the first time the user submits the form. If they submit a second time however, the problem is that the form is posting a full HTTP request.
In the web page the form is wrapped in a span, #add-container. The button within the form is #add-button.
Per the code below, I am trying to re-bind a function to the click event of the buttom whenever the content in the span changes. It seems that this works the first time (i.e. when the document loads), but not subsequent times (i.e. when the XHR response is loaded into the page).
// Add product and services
$(document).ready(function() {
$("#add-container").change(prepareAddForm());
});
function prepareAddForm() {
var uri = '/product/add/org/4/format/html';
$("#add-button").click(function() {
$("#add-container").load(uri, {language: "php", version: 5});
return false;
});
}
Any ideas? Thanks for your assistance...
Sorry - just sorted it out. Needed to use the .live() method!

How to post form using jQuery?

I have a form with a submit button and it works fine, but I now have a user request to make the form get saved (posted to save action) if a link on the page is clicked and the form is "dirty".
I've got the logic in place by having an isDirty JavaScript variable, now I would like to post the form from the JavaScript function when it is dirty.
My form declaration is as follows:
<form id="formSmart" action="<%= ResolveUrl("~/SmartForm/Proceed") %>"
method="post" enctype="multipart/form-data">
and my JavaScript is:
function checkLink() {
if (isDirty) {
$("#formSmart").submit();
}
}
The proceed action doesn't get called, yet when I click the submit button on the form it works fine. What am I doing wrong in the JavaScript?
Note: The call to checkLink() works fine, the ultimate problem is that $("#formSmart").submit(); is not posting to the Proceed action.
You have the correct way of submitting the form based on what you have posted and the names match up.
Are you sure you are calling checkLink and is isDirty equal to true?
Put and alert('Test'); right before you submit and in the if scope.
EDIT: To hookup your event you need to do the following:
$('#yourLinkID').click(checkLink(); return false;);
Note the return false which will cause your link to not execute a navigate. If you want the link to navigate, you can just remove that part.
Sounds like the requirement is that 'a link on the page is clicked'.
Perhaps attach this event to all the <a> tags on the page.
$(document).ready(function() {
// all <a> tags get the checkLink attached to them
$("a").click(checkLink());
});
your problem is that the browser navigate before the page performs your submit.
the solution is suspending the navigation till you save the form.
The UGLY solution:
you could do it buy saving the clicked url at a hidden field,
returning false to stop the navigation,
and after submit check for a value there and if it exists do navigation
A better solution:
post the form via ajax and after the ajax call completes(no need to check for success or error) perform the navigation(to make it really easy just use ajaxForm ajaxForm plugin)
the only problem with this solution is if the link has target="_blank" because then you have to use window.open which might be blocked by popup blockers
you can play with a simple jsbin sample i prepared showing this
this example post some values to an older version of this page + navigate to google, open fiddler and see that it first post and then navigate.
If you went to the jsbin page stop reading here
here is the Html:
<form id="formSmart" action="http://jsbin.com/oletu4/edit" method="post">
<input type="text" name="someLie" />
<input type="text" name="someLie2" />
<input type="submit" value="submit" />
<a id="lnkNavOut" href="http://www.google.com">www.google.com</a>
here is the JS:
$(document).ready(function(){
$("#lnkNavOut").click(function(){
var jqFormSmart = $("#formSmart");
//check here if the form is dirty and needs to be saved
var jqClickedLink = $(this);
$.ajax({
url: jqFormSmart.attr("action"),
type: "POST",
data:jqFormSmart.serialize(),
complete:function(){
location = jqClickedLink.attr("href");
}
});
return false;//stop navigation
});
});​
