Show/hide quick view form fields on page load

I need to hide/show quickview form fields by using javascript. Its throws error. getproperty is undefined.

function getAttributeValue() {
    var quickViewControl = Xrm.Page.ui.quickForms.get("<QuickViewControlName>");
    if (quickViewControl != undefined)
    {
        if (quickViewControl.isLoaded())
        {
            //here i need to hide new_hiddenvale field
        }
    }
}
