deleteMarkedTimespan requires a very specific configuration to delete a marked timespan. For example, if I place a timespan with the start and end date, I need to know the old start and end date in order to delete the timespan on that one single timeline. Instead, if I just pass the sections: {timeline: id} as the config, I would argue that the default behavior should be to delete the markedTimespan on that timeline. Either way, for my purpose, I called
scheduler._delete_marked_timespan_by_config({
sections: { timeline: object.id }
});and added
if(typeof a[h][f] != 'undefined' && typeof d == 'undefined' && e == "default"){
delete a[h][f];
}into scheduler._delete_marked_timespan_by_config located in dhtmlxscheduler_limit.js
I looked for a fix for a while, before I just hacked around it.
Just thought someone might benefit from my solution. Just keep in mind this is only useful when you have one markedtimespan on a timeline. The timelines I have are limited use, and I want a way of notifying the user when the timeline is over so they can remove it from their community.
