Please add some identifiers to lightbox input fields. Right now, I have to use the following code to find some input fields in the lightbox:
var first = $('textarea', $('.dhx_cal_light .dhx_cal_lsection:contains("First Name")').parent());
var last = $('textarea', $('.dhx_cal_light .dhx_cal_lsection:contains("Last Name")').parent());
...
This code is extremely slow, especially on tablets or smartphones. You can automatically add an id to each field like this:
// example
var fieldName = 'First Name';
var fieldClass = 'lightbox-field-' + fieldName.replace(' ', '-');
field.addClass(fieldClass); // add the class 'lightbox-field-first-name' to this field
Of course, you can add an id or a class any other way, but it should be possible to find a specific field some way.
