I am using ajax to gather the CKEditor content and submit it to the server. Once I look at it after it is submitted, all the html tags < and > have been converted to their html entities. This is not what I want, as I obviously need to preserve the HTML.
Is there something I did wrong?
A couple of questions:
Which AJAX library are you using?
What method are you using to fetch the content from CKEditor?
I use jQuery + validate (form validation plugin) for my form submissions.
The textarea to which CKEditor is bound is named body.
For some weird reason when I submitted the form, the content wasn't being submitted at all. Looking into the HTML I found that the textarea wasn't being populated by CKEditor (don't ask me why).
What I did was to just prior to submission, manually grab the data from CKEditor and stash it into the textarea. A single line of jquery should suffice.
$( '#body' ).val( CKEDITOR.instances.body.getData() );
And then proceed with the form submission normally. jQuery has a very good data serialization method - a function called serialize(), which I use to convert the entire form's data into a string. At the PHP end, this string is auto-converted into members of the $_POST array.
You should try the same approach and see if it works for you.
If you're still stuck, post your code here.

In the end I realized that my server was not saving the data at UTF-8 even though ajax was sending it this way. So, I fixed that and the data saves correctly.
Correct is to set up in config this
entities : false

I have a wizard style page that I want to validate a page at a time. So before the user can move off the (partial) page I submit the inputs from the div for validation. Client side validation works OK but on some pages there are one or more fields I need to validate on the server. Yes I know about remote validation.
I can get the server side validation done without a problem. The issue I have is how do I display the errors on the correct fields? I can locate the fields in the div and find the span where the error message is suppose to go. But I just can't get the message to display.
I must be missing something when updating the field span. I would have thouht that there is a jQuery routine to add error information to a field. I need something similar to the controllers AddModuleError. So when I get return from my $.Post I can set error text on the appropriate fields.
Any suggestions?
A potential solution to your problem might be in this article "Client side validation after Ajax Partial View result in ASP.NET MVC 3"
Basically, once you get your html from the post you can invoke validation using jQuery.validator.unobtrusive.parse()
As per the example in the article;
$.post("YourAction", { data: <your form data> },
function(htmlContent){
$('#container').html(htmlContent);
jQuery.validator.unobtrusive.parse('#content')
}
Worth looking into
If you are using the included RemoteAttribute, or the version I linked to in my answer to your other remote validation question, then you should not have to worry about displaying the error, as both work with the ValidationMessage helpers to automatically display errors.
Have you added Html.ValidationMessage(...) or Html.ValidationMessageFor(...) for each field to be validated?
After processing a jQuery Ajax Post from an HTML form successfully within a Go program, how do I load a new form? I first tried sending the form as the response and the Javascript displayed it, but it did not clear the old (existing) form. I then tried within the HTML Javascript to set the URL using "window.location = 'localhost:8088/MaintForm/'". That resulted in a warning from the browser but did not load the form and did not change the URL. I would like to ideally know both methods - via the Go program acting as a server, and via Javascript. If I manually change the URL, the form loads OK. What I am trying to do is receive a response in Javascript (jQuery Ajax), and then request the new form if the response is positive. I would prefer to do this without changing the URL. As I said above, this partially worked.
You would have to put your original form inside a tag, for example a div, and use your JQuery code to replace the contents of that tag with the new form. This way you are not changing the URL.
This is more of a javascript/JQuery question than a go-specific one.
In javascript:
location.href = '/MaintForm/';
In golang, you can use the http.Redirect function, like this:
http.Redirect(w, r, "/MaintForm/", http.StatusFound)
Please note: this appears to be solved by : I just need to do an "document.write(data);" in Javascript. "Data" contains the new HTML.
I'm requesting an ASP.net MVC view into a live box and the view contains form fields that have been marked up with attributes to be used by JQuery's unobtrusive validators plug-in.
The client script is not however working and my theory is that its because the validation framework is only being triggered on page load which has long since passed by the time the MVC view has been loaded into the live box.
Thus how can I let the validation framework know that it has new form fields to fix up?
Cheers, Ian.
var $form = $("form");
$form.unbind();
$form.data("validator", null);
$.validator.unobtrusive.parse(document);
// Re add validation with changes
$form.validate($form.data("unobtrusiveValidation").options);
You may take a look at the following blog post. And here's another one.
Another option, rather trick, which worked for me. Just add following line in the beginning of the partial view which is being returned by ajax call
this.ViewContext.FormContext = new FormContext();
Reference
For some reason I had to combine bjan and dfortun's answers...
So I put this in my view:
#{
this.ViewContext.FormContext = new FormContext();
}
And this execute this after the ajax call finishes:
var form = $("#EnrollmentForm");
form.unbind();
form.data("validator", null);
$.validator.unobtrusive.parse(document);
form.validate(form.data("unobtrusiveValidation").options);
I had a similar issue. I had a form that was using Ajax requests to re-display a part of the form with different form fields. I used unobtrusive validation by manually doing it on the client side using the
#Html.TextBoxFor
for my text boxes. For some reason the validation works when attempting to submit with invalid fields (i.e., the text boxes get outlined in red and the appropriate error messages display with the content I put in the
data_val_required
attribute, for example.
However, after I click a button that makes an Ajax request to modify the form with different fields and then submit again, only the red outline on the invalid fields display, but no error messages are rendered.
bjan's trick worked for me, but I still can't see what was causing the issue. All the HTML necessary to carry out the client-side validation was there I just can't figure out why the error message attribute values wouldn't display.
All I can think of is that the jQuery validation code doesn't make a second attempt to check the form fields after a submit was made.
i am using cakephp in my project. in this at one section i need to update the particular row onclick of the image. using ajax. i used mootools as javascript library. so please help me how could i do this.
thanks in advance
Simply speaking:
Create a CakePHP controller action that performs the row update.
Determine the URL of the controller action you just created. (ie. /controllername/actionname)
Determine if you need to do a GET or POST request to this URL for it to work.
Put code in your view that attaches an "onclick" event that makes and AJAX (GET/POST) request to the above controller.
CakePHP has a javascript helper that traditionally produced Prototype code, but in v1.3 it is now able to produce code for other Javascript frameworks (such as Mootools, jQuery, etc.)
However, many suggest writing your javascript in javascript (eg. actually using the Mootools framwork), rather than writing your javascript in PHP (like using CakePHP's helper to produce Mootools code).
Either way, in your view you need to have something like: <?php echo $js->link(.. or <script>Moo.. or <a onclick="Moo.. to attach your Javascript to that link.
You may also wish for your controller action to return some sort of response indicating whether or not the row update failed or succeeded. In that case you need to make sure the CakePHP controller action you are calling has a view that outputs this. JSON seems to be the ideal format for this (eg. { success: true }), but you need to remember to turn off Cake's debug output. This response can be captured into a variable by your Mootools code where you can decide what to do with it (eg. displaying an error).
As i know most programmer work with protype.js library.

When we use AJAX for validation the response comes through xml file and in case of javascript the response comes through html page.
Is it true or false ?
please explian both the cases.
Ajax can return pretty much anything. Your particular application or implementation might be returning XML, but Ajax commonly returns JSON and HTML as well. But it can return TXT or just status codes ..
AJAX is such a broad term that both of your cases can be called like that. Basically every call from already loaded page is AJAX even if it's done by dynamically creating tag or refreshing iframe.
actually Ajax is nothing but a term to describe what is happening, the response comes as an xml or html depending on what you want it to return, it is a string that ajax returns, in Javascript it is up to you what to do with that string, want to parse it as XML node? want to display it immidiately in an element "innerHMTL" or want to alert the returned string... the power of ajax is not what it returns, it is what it does on the server (remotly) without having to send the whole page in.
AJAX there can be any type of return text. With Javascript it can work on the DOM object and get anything from the page.
The main difference, AJAX a request goes to the server and the result is returned.
