onBeforeBranchLoading

if dynamic loading is enabled, fires after a user expands the task branch but before loading starts

settings

object

an object which contains the task id and request URL

boolean

Available only in PRO Edition

Example

gantt.attachEvent("onBeforeBranchLoading", function(settings){
    var task = gantt.getTask(settings.taskId);
    config.url += "&value=" + encodeURIComponent(task.text);
    return true;
});

This event can be used to add extra parameters to dynamic loading requests. The settings object contains two properties - the id of the task and the request url:

{
   taskId: 1,
   url:"/data?parent_id=1"
}

The request url can be modified from code.

This event fires only when Dynamic loading is enabled.

The event is blockable, returning false will cancel the dynamic loading request.
