Get the form id

Hello,

Is there a solution to get the FORM id with the idea of one of the input field? :

{ view:"form", id:"topForm1", data:[
	   {type:"text", id:"field_a", label: 'saisie1', click :"doSomething",value: "", inputWidth: 250, labelWidth: 100, align: "center", labelAlign: "center"}, ] 
}

when the function : doSomething is called i get the id of the input field, but how can i get the id of the form with it?

Regards.

function doSomething(id,e){
var formId = this.config.id;

}
