#UiField Hyperlink historyLink;
this.historyLink.getElement().setAttribute("rel", "nofollow");
This sets the rel attribute of the containing div.
<div class="gwt-Hyperlink" rel="nofollow">history</div>
How do I get at the a tag?
You can get a element this way
Element a = historyLink.getElement().getFirstChildElement();
Maybe you can use an InlineHyperlink instead (if you don't want the div wrapper at all), but actually I don't understand the use of rel=nofollow on a link with a #hash-only href: if that's for Google AJAX crawling, can't you simply avoid outputting the link in the HTML snapshot you send in response to an _escaped_fragment_ request?

Is it possible to use ckeditor on a form input instead of textarea, i am building a CMS and now trying to add ckeditor and majority of of fields are form input not textarea
Thanks in advance
You can use CKEditor on an element (a div, say) that has contenteditable set. In fact, by default contenteditable elements will have CKEditor editors instantiated. It seems unconventional to use a rich text editor on an input of type text but I imagine it could be done.
As far as I know CkEditor has to be created using a textarea. In saying this, I am using it in a Razor MVC view and its one of the classes in my form..
The request will be blocked though and you will get this error;
A potentially dangerous Request.Form value was detected from the
client
To get around this, you need to get the value of the CKEditor text and html encode it. You can do this
when submitting your form, intercept it on the onsubmit function:
<form id="myform" onsubmit="javascript:onFormSubmit(this);return false" >
...
</form>
Then in this onFormSubmit function
Get the value,
Set the property value to the url encoded value
Do a ajax call to your server with the data
Your function will get the CKEditor encoded value like so:
function onFormSubmit(form)
{
var editor = CKEDITOR.instances["EditorId"];
var richtextValue = editor.getData();
var urlEncodedValue = encodeURIComponent(richtextValue);
// TODO rest of code doing ajax post to submit your form and its data
// Here you need to do an ajax call to your server pass it the form data along with the url encoded CKEditor value for that property
}
I use SHtml.jsonForm in myjsonclass.show to wrap a jsonform to the HTML page with the following command:
<div id="form" class="lift:myjsonclass.show">
It works fine.
The SHtml.jsonForm method defines a random id for the form tag, I wonder if there is a solution to get that id and use it in the HTML. It will make easier for example to apply form validators in Javascript.
I have solved that by accessing a known element of the form and asking for its parent in javascript: element.parent(); So I am able to get id of the form with: element.attr('id').
I have this xml as part of the responseXml of an Ajax call:
<banner-ad>
<title><span style="color:#ffff00;"><strong>Title</strong></span></title>
</banner-ad>
When I used this jQuery(responseXml).find("title").text(); the result is "Title".
I also tried jQuery(responseXml).find("title:first-child") but the result is [object Object].
I want to get the result:
<span style="color:#ffff00;"><strong>Title</strong></span>
Please let me know how to do this in jQuery.
Thanks in advance for any help.

Your problem is that you cannot simply append nodes from one document (the XML response) to another (your HTML page). The issue is two-fold:
You can use jQuery to append nodes from the XML document to the HTML page. This works; the nodes appear in the HTML DOM, but they stay XML nodes and therefore the browser ignores the style attribute, for example. Consequently the text will not be yellow (#ffff00).
As far as I can see, jQuery offers no built-in way to get the XML string (i.e. a serialized node) from an XML node. jQuery can handle XML documents quite well, but there is no equivalent to what .html() does in HTML documents.
So to make this work we need to extract the XML string from the XML document. Some browsers support the .xml property on XML nodes (namely, IE), the others come with an XMLSerializer object:
// find the proper XML node
var $title = $(doc).find("title");
// either use .xml or, when unavailable, an XMLSerializer
var html = $title[0].xml || (new XMLSerializer()).serializeToString($title[0]);
// result:
// '<title><span style="color:#ffff00;"><strong>Title</strong></span></title>'
Then we have to feed this HTML string to jQuery so new, real HTML elements can be created from it:
$("#target").append(html);
There is a fiddle to show this in action: http://jsfiddle.net/Tomalak/QWHj8/. This example also gets rid of the superfluous <title> element.
Anyway. If you have a chance to influence the XML itself, it would make sense to change it:
<banner-ad>
<title><span style="color:#ffff00;"><strong>Title</strong></span></title>
</banner-ad>
Just XML-encode the payload of <title> and you can do this in jQuery:
$("#target").append( $(doc).find("title").text() );
This would probably work:
$(responseXml).find("title").html();
I am trying to target a specific div with the results of a form post.
I have found the below code, but am unclear on where the URL for the page that handles the form data is specified. Any help greatly appreciated.
$("form1").submit(function() {
$.post($(this).attr("action"), $(this).serialize(), function(html) {
$("#someDiv").html(html);
});
return false; // prevent normal submit
});
For example, I want to send form id="form1" to somepage.php, and have somepage.php displayed into div id=someDiv.
In that code-snippet, $(this).attr("action") is the URL: it's taken from the action="..." attribute of the <form> element. If, for whatever reason, you don't want to use that attribute to specify the URL, you can replace $(this).attr("action") with an explicit URL (as a string).
It is defined in the action attribute of your form tag
Is it possible to create Ajax.ActionLink which has instead of text, the whole DIV?
I'd like to map div on Ajax.ActionLink
I don't think that this will work using the standard MVC Ajax scripts. I believe that the MVC javascript is created to use an <a> element by default. On a different note, embedding a div tag within an <a> is not valid XHTML. What are you trying to achieve?
Using Jquery is probably the easiet way you want to go. As an example:
<div onclick="SomeAjaxFunction()">some div content</div>
function SomeAjaxFunction()
{
$.get('<%= Url.Action("SomeAction", "InSomeController") %>', function(data) {
$('.result').html(data); // assuming a partial view
alert('Load was performed.');
});
}
However, if you are dead set on using MS Ajax, to work with divs, you need to possibly look at the Sys.Mvc.MvcHelpers._asyncRequest function and do some of your own re-wrapping to make it usable. I have not tried or tested this, so use at your own risk. (Stick with the Jquery, there is far better help and support available.)
