Re: [TRINIDAD] Javascript sendPartialFormPost - how to read param in bean

[Elmar Kretzer]

Thanks for your response Cédric,

that seems to be a clean approach.
Furthermore this way it should also be possible to to avoid writing
TrPage.getInstance().sendPartialFormPost(myForm,
                                             {source: "myButton"},
                                             {});

and instead make use of e.g. jQuery(''#mybutton).trigger("click").




But does anyone know if it is possible to read those PartialFormPost  
Params?

TrPage.getInstance().sendPartialFormPost(
    theForm,
    {param1: "value1", param2: "value2"});

Maybe from the RequestContext ?

I don't know the answer either (and I'd be glad to know it, btw), but
what I do is that my javascript code updates form fields (hidden if
necessary) with values I want to send back :

in jspx :
...
function myfunc()
{
 document.getElementById("param1").value=someValue;
 TrPage.getInstance().sendPartialFormPost(myForm,
                                             {source: "myButton"},
                                             {});
}

...
<tr:inputText type="hidden" id="param1" value="#{myBean.param1}"/>
<tr:commandButton action="#{myBean.doSomething}" id="myButton">

in bean :
public String doSomething()
{
 String s=getParam1();
 ...
}

Note that :
-you can hide the button as well (with inlineStyle)
-everything will work as is you clicked the button. So you can use
partialTriggers, partialSubmit, etc. referencing the button, je
javascript code will do the same.
-I think the Trinidad documentation should have a similar example. I
spent hours figuring out that "source" thing !

Hi everyone,

when i am triggering a partial submit via javascript and add e.g.  
param1 to
the call,

how can i read the value of the param in the bean from the  
FacesContext ?

Javascript Code:

TrPage.getInstance().sendPartialFormPost(
    theForm,
    {param1: "value1", param2: "value2"});

any clues?

Thanks in advance
