Passing reference to current form to javascript

[schenger]

Hey,

i would like to disable all inputs in a form during ajax request. Therefore i call a javascript function and i try to pass the current form reference. The problem in javascript is the form reference undefined. Can i pass current form reference like: disableElements(this.form);

<rich:inputNumberSlider id="slider"
    value="#{node.submittedValue }"
    valueChangeListener="#{handler.valueChanged }"
    label="#{node.name }"
    inputPosition="top"
    width="400"
    showInput="true"
    enableManualInput="true"
    minValue="#{node.min}"
    maxValue="#{node.max}">
    <a4j:support event="onchange"
        onsubmit="disableElements(this.form);"
        requestDelay="1000" status="commonstatus"
        reRender="part" />
</rich:inputNumberSlider>

or is it possible to block only a part of the page with modalpanel?

thank you very much

In the javascript you can directly access the "form" object many way, like

var frm = document.forms[index];

here by using index you can get the required form if there are multiple form inside same document.

you can directly get form object of element like this,

var form = element.form;

if you pass the object 'this'   check what you are getting the in javascript  by giving alert like alert(object.id)

Hi Deb Dutta,

thank you for reply.

var frm = document.forms[index];

In my case this is a portal page so there are many forms and the index of the form can be different. Also i cannot give id to the forms so i could not use

document.getElementById('formid'). They are generated elsewhere.

if you pass the object 'this'   check what you are getting the in javascript  by giving alert like alert(object.id)

I've tried that. I can see 'undefined' in the alert message.

maybe other ideas?

thanks a lot.

hmm...understood,

for the element  get the parent  form id where it is included  and can pass it like this

  onsubmit="disableElements('formid);

then in the js method get the form object,

var formobj = document.getElementById(formid);
