MSCRM 2011 Hiding Tab based on value of statcode field

Question

I want to hide a tab in Quote entity based on value of statecode field of quote entity.

Senario: If the value is equal to ''3'' tab should be visible, if not tab should be invisible. You can find my code below but it's not working.

Please help, thanks.

   function hideTab(){
var field = Xrm.Page.data.entity.attributes.get("statecode");    
if (field == null || field.getValue() == null)
    return;
var value = field.getValue();
if(value != "3")
    return;

Xrm.Page.ui.tabs.get(tab_9).setVisible(false);
}

In order to read the field value using JavaScript, the field must be in the body of the crmForm (i.e. not in Header or Footer areas).

Additionally, I would refactor your code like this

function hideTab (){
    var field;
    var fieldValue;
    var isHidden = false;

    field = Xrm.Page.data.entity.attributes.get("statecode");    
    if (field != null && field.getValue() != null){
        fieldValue = field.getValue();
        alert(fieldValue);
        if(value != "3")
            isHidden = true;
    }

    alert(isHidden);
    Xrm.Page.ui.tabs.get('tab_9').setVisible(isHidden);
}

Notice I've added a couple of alerts so that you can check that

1. the function is running
2. the field is found
3. the field value is correct
