how to use a4j:jsFunction to connect String parameter

[feuyeux]

There is a inputText and a button as the input components, and a outputText will print result.

How to use the a4j:jsFunction to set the outputText to obtain a summary result:

for instance, the first time, we input 1 and click the button, the print string is 1. And then input 2, we gain 1_2 ...

Thanks!

Hi Lu,

you can pass parameters using  <a4j:actionparam name="param1" assignTo="#{userBean.name}"  /> and you should use reRender to update your target. See http://docs.jboss.org/richfaces/latest_3_3_X/en/devguide/html/a4j_jsFunction.html for further information.

Best regards,

Mark

Thanks Mark.

Please consider:

At first time, we set the outputText as param1, whose value is #{userBean.name},

but at he seconde time, the outputText will be new param1, it's not old param1 plus new param1.

Is it clear? I like to provide the js to express it more:

function test(param1){

     var x=outputText.value; -- pseudocode

     outputText.value=x+param1;

}
