Hide/Show FieldLabel in ExtJs form

This is an overriding function to enable hide/show fieldLabel in ExtJs field form.
The current release of ExtJs 2.1 does not support it.

You can use the function hideItem and showItem in order to show/hide the form field.

Put this function in a javascript file eg. ext-override.js
Then include this file into your html file containing ExtJs form.

Ext.override(Ext.form.Field, {
    hideItem :function(){
        this.formItem.addClass('x-hide-' + this.hideMode);             
    },

    showItem: function(){
        this.formItem.removeClass('x-hide-' + this.hideMode);             
    },
    setFieldLabel: function(text) {
    var ct = this.el.findParent('div.x-form-item', 3, true);
    var label = ct.first('label.x-form-item-label');
    label.update(text);
  }
});
