When a form with a textarea using CkEditor is submitted using ajax the post is empty on the server side.
If I remove CkEditor, the value is posted. Any ideas?
On submit, run this code:
for (instance in CKEDITOR.instances) {
CKEDITOR.instances[instance].updateElement();
}
.. basically for AJAX, you need to force CKEditor to update your textareas so they contain the data you see in the CKEditor windows. See this question for more details.
You don't really need to update anything with JS. All you have to do is to make sure your textarea (the one you replace with CKEDITOR.replace() on $(document).ready()) has the same name as the property you want to set value of, e.g.:
<textarea id="editor" name="Body">#Model?.Body</textarea>
This works for me:
CKEDITOR.replace( 'content' );
function updateAllMessageForms()
{
for (instance in CKEDITOR.instances) {
CKEDITOR.instances[instance].updateElement();
}
}

In previous versions(3.5) of CKEditor I was able to enter:
<br style="page-break-after: always;" />
However, after upgrading to 4.4.5, I noticed that the RTE no longer shows this HTML source, from the Database column, and so if one resaves the form with this RTE on it, then NULL is saved back to the database. It seems that CKEditor is stripping this HTML out for some reason.
How can I prevent this?
Many thanks.
EDIT 1
Discovered this to be added to config.js:
config.allowedContent = 'br {page-break-after}';
But does not work, although it should do....
EDIT 2
Link for above config setting
EDIT 3
I can try to enter the above HTML, in HTML Source View, but if I toggle the HTML Source button, and go back to Source View, it is now gone. So CKEditor is stripping this HTML out for some reason.
EDIT 4
Removed as now irrelevant
EDIT 5
Looking at the Browser source I see:
<textarea class="RuleRTE" cols="20" id="myCk" rows="2"><br style="page-break-after: always;" /> </textarea>
So clearly the data is there and being retrieved, but being converted which prevents me seeing it in the HTML Source view.
I have now found this is irrelevant as <p>test</p> test fine and it gets converted as well, I guess to prevent it being rendered like normal HTML in the page. So it seems the CKEditor does not like the tag ???
EDIT 6:
Removed as now irrelevant to question.
EDIT 7:
Debug JS:
<script type="text/javascript" language="javascript">
var editor = CKEDITOR.replace('Content', {
allowedContent: 'br[*]'
});
editor.on('instanceReady', function () {
console.log(editor.filter.allowedContent);
});
Results seem to show allowedContent is working fine, but BR element still invisible.
[Object, Object]
0: Object attributes: true
classes: null
elements: Object br: true
I suspect that there's a syntax or usage error with the way you're attempting to modify the allowedContent setting. Try doing something more simple along these lines: (do it in code rather than the config file)
var your_ck_editor = CKEDITOR.replace( 'your_ck_element_id', {
allowedContent: 'br[*]'
} );
The br[*] setting should allow any <br /> element with any attribute.
For troubleshooting purposes try this:
console.log( your_ck_editor.filter.allowedContent );
If this code does not work for you please post all the code that you use to set up your CKEditor as well as the output of your console.log call.
I have a section of a form that dynamically loads different sets of fields based on the user's selection in a control. I'm using a javascript event handler to detect when the selection changes, and using AJAX (with HTML payload) to pull in the proper set of fields.
I would like to be able to use Laravel's Form::getValueAttribute() method to automatically fill in the form fields' values in both the static and dynamic form parts. However, the partial view that is loaded by my AJAX call does not have the same instance of the Form class as the view with my main Form, so I can't simply call getValueAttribute() in the partial.
My thought is to make the AJAX call a POST, and serialize the necessary data (a subset of Input::old() or the model data depending whether the page is loaded as the result of validation errors, or an UPDATE request) to send along with the POST so that the HTML fragment I get back has the values set properly.
Is this the best way to get what I want? If so, does Laravel have any tools to help with the serialization of form data? If not, what might be a better approach?
I've found an approach I like better. When the view is loaded normally I use AJAX as usual to load the partial. But when the view is loaded for a validation post-back or for editing, I use Laravel's Views' nest method to nest the partial view containing the proper fields directly into the response. The partial then has access to all the Input and error data I need. The user is still able to change the field set as usual but I put up a confirm prompt for them if they have already set some values in a field set they previously selected. If they decide to proceed anyway, the field set is cleared and a new field set is brought in via AJAX as usual.
My code looks something like this:
Controller:
public function newThing() {
if ( Request::session()->has('errors') ) {
// this is a validation post-back
return View::make('thing')
->nest('fields', 'fields_partial');
} else {
// just a normal unfilled form
return View::make('thing');
}
}
public function editThing() {
return View::make('thing')
->nest('fields', 'fields_partial');
}
View: thing.blade.php (just a snip of it)
...
<form>
...
<select id="picker">...</select>
<div class="sub-fields">
{{ isset($fields) ? $fields : '' }}
</div>
...
</form>
...
<script>
$('#picker').change(function() {
// if any .sub-fields inputs have been changed, get confirmation from the user
// if user confirms, do ajax stuff to replace .sub-fields contents with new field set
// otherwise cancel the change
});
</script>
Can some one help me..
I have a script who generates code like this >>
<div id="imageok">img1.png</div>
<div id="imageok">img22.jpg</div>
<div id="imageok">img333.gif</div>
In AJAX the name of the image is called imgname its equal to content of the div.
I want to replace the text inside the div but I can't use the id because its the same for each div.. I tried to search for div by it content (I have the name of the image in the AJAX)
Perhaps its something like..
GET element where content =="img1.png" > replace
I just can't write it correct..
Please help me .
I think what you are trying to do can be accomplished more 'neatly' with jQuery.
Have you used jQuery before? If yes, then you can do something like this:
// get content into a variable called 'result'
$('div').each(function(i) {
if ($(this).text() == 'img1.png') {
$(this).text(result);
}
});
I haven't tested this code. Hope it helps.
jQuery.validate stops my form from being submitted. I would like it to just show the user what is wrong but allow them to submit anyway.
I am using the jquery.validate.unobtrusive library that comes with ASP MVC.
I use jquery.tmpl to dynamically create the form and then I use jquery.datalink to link the input fields to a json object on the page. So my document ready call looks something like this.
jQuery(function ($) {
// this allows be to rebind validation after the dynamic form has been created
$("form").removeData("validator");
$("form").removeData("unobtrusiveValidation");
$.validator.unobtrusive.parse($("form"));
// submit the answers
$("form").submit(function(e) {
$("input[name=jsonResponse]").val(JSON.stringify(answerArray));
return true;
});
}
I note that there is an option
$("form").validate({ onsubmit: false });
but that seems to kill all validation.
So just to recap when my form is rendered I want to show all errors immediately but I don't want to prevent the submit from working.
So after some research (reading the source code) I found I needed to do 2 things
add the class cancel to my submit button
<input id="submitButton" type="submit" class="cancel" value="OK" />
This stops the validation running on submit.
To validate the form on load I just had to add this to my document ready function
$("form").valid();
Hope this helps someone else
I am using CKEditor on my page. It is working fine except when I post back. I am getting this error:
A potentially dangerous Request.Form value was detected from the client (ctl00$MainContent$txtDesc="<p>
</p>
I am using this code to put CKEditor value into textbox on OnClientClick event of submit button:
function getEditorValue(){
var editor=$("#<%= txtDesc.ClientID%>").ckeditorGet();
editor.updateElement();
return true;
}
Have you tried setting the htmlEncodeOutput property?
> CKEDITOR.replace('#<%= txtDesc.ClientID%>', {
> htmlEncodeOutput: true });
This should encode the output and you should be able to avoid setting the requestValidationMode.
Documentation for it is here: ckEditor documentation
Set ValidateRequest="False" in your <% #Page declaration.
