I have a Yii CActiveForm backed with a CFormModel and I'm using the onChange htmlOption to call the javascript send().
The send function tweeks some of the form variables and populates a hidden field ready for form serialising and POSTing back to the server.
My problem is that I don't know how to reference the form fields from inside the javascript function using jQuery because the CActiveForm changes their names. Currently I'm having to hard code the names eg $('#SearchForm_myvar').val("myval"); which doesn't seem right.
How can I reference the form variables inside the javascript code?
Found the answer from the source so putting it here in case someone else wants it.
The jQuery id is:
"#" . CHtml::activeId($model,'myvar')

I was able to get Aurelia-validation working on a dynamically created form when using the compose element, but I've switched to custom elements for better encapsulation and reuse of the custom controls. However, now my validation seems to be half-broken.
https://gist.run/?id=6e97538c3888cae0f6134faed9d67362
Issue 1: The ValidateBindingBehavior is not doing anything. I suspect it's not finding the controller or matching the rules since the property name is not easily visible in the binding (due to dynamic controls).
Issue 2: For some reason validate() on submit actually only shows the first error instead of all of them. That indicates a problem but I don't know what.
Can anyone get the attached GistRun to work properly?
I need to call a CSJS function which uses JQuery. The tricky part is I need to call it after the Dojo parser has completed.
The CSJS function is calling $('#pageContainer input[type!="hidden"], #pageContainer select, #pageContainer textarea').serialize();
I need to call serialize() after the Dojo parser has completed otherwise I won't have the Dojo date fields in the serialized string.
I've tried putting the call in a script block at the bottom of the page like this: $(function() { serializeForm() }); but this is running before the Dojo parser has completed because my date picker field is missing.
I've also tried doing dojo.ready(serializeForm()) but that gave me an error:
TypeError: context is not a function
info: context is not a function
The error is coming from dojo.js line 1862
FYI: The purpose of serializing is to do a "is form dirty" check when the user tries to navigate away from the page (I had no luck with the enabledModifiedFlag I think because my app is using the dynamic content control to switch pages).
ready is expecting a call back function, remove the parenthesis, or wrap in anonymous function
dojo.ready(serializeForm)
or
dojo.ready(function(){serializeForm()})
I have an Aurelia application in which I'm trying to build a CMS component. This component will load data from the server and this data mainly contains slug, title and content fields.
I also have several global components defined in my application, and I want to be able to use those components in the server so when I pull that data my CMS component is able to transform/compile those custom elements.
An example would be a tab component. I have the tab component with this structure defined:
<tab-panel>
<tab title="First"></tab>
<tab title="Second"></tab>
</tab-panel>
The CMS component will contain a content property which I use to pass a string like this: '<tab-panel><tab title="First"></tab><tab title="Second"></tab></tab-panel>'
The component needs to compile that string and render it in its view. I've checked the enhance API, but it doesn't worked, at least for me. Any other suggestion to dynamically compile/render custom elements??
Thanks a lot in advance.
I've found the solution. I've used a compose element and InlineViewStrategy and it worked well, the components are shows and binding works as expected.
If your custom elements are registered globally using globalResources you can actually using the TemplatingEngine to dynamically insert content into the DOM and then compile it after-the-fact. This blog post goes into detail in how you can do it.
However, I would use this as a last resort. As is mostly always the case, there are much better ways to do something in Aurelia. Using the <compose> element is a great way to dynamically render content in your Aurelia applications and should always be the first port of call.
I have a seaside application with a master-detail page. The master page has a table that consists of a list of tr records. When the user clicks a particular tr element, I want to call a detail component, which'll show the individual record's data.
Since I cannot make a tr element with callback or have it contain an anchor with a callback, I want the tr's onClick property to have some JavaScript which'll call: subcomponent . When I tried this, I got an error saying call: can only be used in callbacks and tasks.
Using ajax is a workaround, however it breaks the back button.
Edit:
More generally, I'd like to know how to set callback like behaviour for various JavaScript events.
Well, you cannot render a component in a tr element, but you could add some anchor or other element in one of its td children.
For my project I did roughly the following: I added an anchor to each row with a special css class, e.g. '.dblclick-action'. This anchor has a normal Seaside callback.
Then I bound a dblclick handler to the tr element that does something like document.location=$(this).find('.dblclick.ction').get(0).href;
I am not close to a Smalltalk image now to give you source code, but I hope you get the idea: you don't use Ajax to click the link in that particular row, but instead have the browser navigate to the callback that is associated to the link in that row. You could say you use the tr.'s dblclick handler to click the link and then let the normal Seaside stuff do its work. No magic there. You can find a little bit more info here.
If you don't want the anchor to be visible you may want to experiment with making the anchor invisible (display: none) or the like.
If you are a bit more experiment friendly, you can also try saving a callback on the server and render its url with callback id as an attribute of the tr element and use the dblclick handler to follow the link from that attribute you extract the value of an attribute in query using attr().
I forgot to answer your initial question: you cannot issue a call: from javascript. But you can use the document.location trick to re/misuse an existing link to a callback on the page using the technique I described in my first answer.
I am using an .aspx page as cluetip bound to an anchor tag. I need to pass a parameter from anchor to this page and then call a WCF service to populate my template with returned JSON. I tried putting body onload function but that doesnt seems to work.
Thanks
Koby.

You want to use the .mouseenter() event. This new event in 1.4 is better than .blur() which is what you will see in most examples (and probably why you can find it, a search of blur jquery popup should give you lots of examples). But mouseenter is better in the lastest jQuery
Docs: (very nice example code at the bottom of the page.)

old version
just add the function to the onclick handler. You can do this in jquery with something like this
$(selector).click(function () {
code to do stuff (call wcf and populate)
you can use $(this) to see what was clicked on. ("passed" as you put it)
});
see fab new jQuery docs http://api.jquery.com/click/
