jQuery Question

FullCalendar Horizontal Time Range Selection

Can someone tell me how to achieve something like below image.
How can I select particular time range in selected days.

Notice that the selection spans multiple days. It's a horizontal selection across multiple days (as opposed to a continuous one).

I am using fullCalendar jquery library.

So, the exact thing you need to do isn't quite possible unless you want to heavily modify FC. But you can do something quite close:

horizontal FC selection


Basic Algorithm

  • Turn on selectHelper so that FC will attempt to render it as an event.
  • In eventRender, stop the helper from actually rendering. Instead, take its start and end dates and chunk them into one event per day.
  • Render the chunked events.

Chunking and Rendering

// Chunks a multiday event into an array of events
// i.e. From {start:"2015-05-06T11:00",end:"2015-05-08T15:00"}
//      into [ {start:"2015-05-06T11:00",end:"2015-05-07T15:00"},
//             {start:"2015-05-07T11:00",end:"2015-05-08T15:00"} ]
var chunk = function (event,type) {
    var chunked = [];
        //diff = moment.duration(event.end.diff(event.start));
    if (event.start.format('HHmm') > event.end.format('HHmm')) {
        return false; //Can't chunk, starttime > endtime
    for (var day = event.start.clone(); !day.isAfter(event.end,'day'); day.add(1,'day')) {
            id:"chunked-"+type //Used as a flag in the render function
    return chunked;
// Takes an event and renders it chunked. Also remove the previous chunked-helper.
// Runs after a timeout and only once.
var renderChunkedHelper = (function(){
    var id = 0;
    return function(event){
        id = window.setTimeout(function(){
            var chunked = chunk(event,"helper");
            eventToChunk = null;
            $("#calendar").fullCalendar( "removeEvents", "chunked-helper");
            for(var i = 0; i < chunked.length; i++){
                $("#calendar").fullCalendar("renderEvent", chunked[i]); //Manually render each chunk
        },0); //delay in ms. Could be tweaked for optimal perfomance


FC options

    selectable: true,
    selectHelper: true,
    select: function( start, end, jsEvent, view ){
        if(window.confirm("Create this event?")){
            $("#calendar").fullCalendar( "removeEvents", "chunked-helper");
            $("#calendar").fullCalendar( "addEventSource",chunk({start:start,end:end},"event"));
            $("#calendar").fullCalendar( "removeEvents", "chunked-helper");
    eventRender: function (event,element) {
        if(event.className[0] === "fc-helper"){ //if it's the drag event
            return false; //don't actually render the select helper
