: how to get the id of the current element to pass it to a function

Hi Tobago friends,

 

I have a question for all JSF users (th'at's why I wrote +obago for those who have filters). I'd like to let each user choose what he wants displayed in his/her label and link fields. So I wrote a function that I'd like to call this way for example:

 

 &nbsp; &nbsp; &nbsp; &nbsp;   ; <tc:column >

 &nbsp; &nbsp;   ; &nbsp; &nbsp; &nbsp; &nbsp;   < tc:link label ="#{itf:toString(contract.client, 'xxxx' )}"></ tc:link>

 &nbsp; &nbsp;   ; &nbsp; &nbsp; </tc:column >

 

Where I'd like to have in xxxx the id of the current element.&nbsp; Does anyone have a solution to insert it automatically through javascript or an el expression?

&nbsp;

I think javascript could be a good candidte sth like

 

function( tag ) {

 ; return tag.id;

}

&nbsp;

But I'm really bad in js, I don't know when it gets called, how to call it to fill in the value at page load, and fetures like that...

 

I'd be very happy if someone can help.

&nbsp;

Cheers and folks,

Zied

Hi Mario,

 

Thanks!!! that's great to know. I'll try to search the document for xxxx and replace with the element id.

 

Though&nbsp;I prefer to let this solution as the no solution approch, In fact I planned to do my own xx:link and xx:label that gets its own id and pass it transaparently with no impact on the owning page...

 

Anyway it's a great thing to know in general.

Hi Zied,

 

I think the tag <tc:script/> is the solution. It has several attributes like "onload" or "onexit". You should place it inside <tc:page>. Here a skeleton:

 

<f:view>

 <script language="javascript">

 &nbsp; &nbsp; &nbsp; &nbsp;   ; function doIt(){

 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; &nbsp; &nbsp;   ;  alert("Welcome");

 &nbsp; &nbsp; &nbsp; &nbsp;   ; }

 </script>

 <tc:page>

  <tc:script onload="doIt()"/>

  …your content…

 </tc:page>;

</f:view>

 

Hope it helps.

 

Regards, Mario

Hi Simon,

 

I have a Facelets function wich will act on the server side:

&nbsp; - each user will be able to have its rows in database for specifying the pattern he want to have for a given id

 

For example&nbsp;let's say the pattern is simply an el expression:

  whan I use my facelets tag xx:link it gets the id of the tc:link element it contains and passes it to the facelets function. This one gets the corresponding el expression and returns&nbsp;the resulting&nbsp;string of itf:toString(contract.client, 'correspondingEl'

 

where correspondingEl is for example: "#{client.lastName} entred: #{client.entryDate}&quot; for the user1

and "#{client.lastName} sponsored #{client.sponsored.size}" for user2, both expressions will be in database under the key : "JSF id of the link"

 

For me it's important that this happens as transparently as using a standard tag. The content of the template tag can contain js code naturally, but it inspects alone the id of its content.

 

Regards,

Zied
