I have a basic gantt chart set up with an array of projects with each task that looks like this:
{
text: "test title"
start_date: "2020-03-21"
end_date: "2020-03-27"
projectNumber: "3525"
id: 95
}
I have my date_format set like this:
gantt.config.date_format = '%Y-%m-%d';
The data loads fine and the chart gets populated with the data but when I go to get a task by Id or show all chart tasks, the output shows the dates as objects and not as strings like I originally set them. This is an example output:
text: "test"
start_date: Sat Mar 21 2020 00:00:00 GMT-0400 (Eastern Daylight Time) {}
end_date: Fri Mar 27 2020 00:00:00 GMT-0400 (Eastern Daylight Time) {}
projectNumber: "48"
id: 9
progress: 0
$no_start: false
$no_end: false
$rendered_type: "task"
duration: 6
$source: []
$target: []
parent: 0
$rendered_parent: 0
$level: 0
$open: false
$index: 0
Why aren't the start and end dates strings in the same format that I inserted them as? Is this default behavior of the gantt chart?
Yes, it is by design. Gantt works directly with the date objects. If you want to save the data in a JSON variable, you can use the gantt.serialize() method, and the dates will be converted to strings:
