onContextMenu y-axis

Scheduler Javascript
#1

I am using DHTMLXscheduler v4.3 in timeline mode. I have implemented the onContectMenu handler but it works on the whole component. I want to show different menu options depending on where the user clicks. I can identify if they click on an event or on whitespace but I cant find a way to determine if that whitespace is a section in the left side y-axis. I want to identify which row(section) was clicked in specifically in the left y-axix column. Any help would be appreciated.

Thanks

Hello Trev,
To show the menu when it is called on the “event line”, you can check if there is an event id on click:

scheduler.attachEvent("onContextMenu", (eventId, nativeEventObj) => {
    if (eventId) {
        // menuEvent call
    }
}

To show another menu when it is called on the left side in the “sections” area, you can define the position of the cursor when clicked:

scheduler.attachEvent("onContextMenu", (eventId, nativeEventObj) => {
    var scellWidth = document.getElementsByClassName('dhx_matrix_scell')[0].clientWidth;
    if (nativeEventObj.clientX < scellWidth) {
        // menuSection call
    }
}

To determine in which “section” the click was made, you can use the scheduler.getActionData() method:

var actionData = scheduler.getActionData(nativeEventObj);
dhtmlx.message(`You clicked on section ${actionData.section}`);

You can also use dhx.ContextMenu for the context menu.
