Dynamic event calendar in javascript

This JavaScript code example helps you to create a dynamic calendar widget. It renders days, months, and years dynamically into a div element. The calendar widget comes with a user-friendly interface to navigate the next and previous month.

How to Create Dynamic Calendar in JavaScript

1. First of all, create the HTML structure for the basic interface of the calendar as follows:

         

    

        

        

            ‹
            ›
        
        
        

Jump To: 
      
                 Jan
                 Feb
                 Mar
                 Apr
                 May
                 Jun
                 Jul
                 Aug
                 Sep
                 Oct
                 Nov
                 Dec
             
                    
        
    

You can place the above HTML anywhere on your webpage where you want to display the calendar. If you want to change the language, set it through the data-lang attribute. The available languages are as follows:

• en for English [default]
• id for Indonesian
• fr for French

2. After that, style the calendar using the following CSS styles. You can set the custom CSS values in order to change the interface of the calendar according to your theme.

.wrapper {
    margin: 15px auto;
    max-width: 1100px;
}

.container-calendar {
    background: #ffffff;
    padding: 15px;
    max-width: 475px;
    margin: 0 auto;
    overflow: auto;
}

.button-container-calendar button {
    cursor: pointer;
    display: inline-block;
    zoom: 1;
    background: #00a2b7;
    color: #fff;
    border: 1px solid #0aa2b5;
    border-radius: 4px;
    padding: 5px 10px;
}

.table-calendar {
    border-collapse: collapse;
    width: 100%;
}

.table-calendar td, .table-calendar th {
    padding: 5px;
    border: 1px solid #e2e2e2;
    text-align: center;
    vertical-align: top;
}

.date-picker.selected {
    font-weight: bold;
    outline: 1px dashed #00BCD4;
}

.date-picker.selected span {
    border-bottom: 2px solid currentColor;
}

/* sunday */
.date-picker:nth-child[1] {
  color: red;
}

/* friday */
.date-picker:nth-child[6] {
  color: green;
}

#monthAndYear {
    text-align: center;
    margin-top: 0;
}

.button-container-calendar {
    position: relative;
    margin-bottom: 1em;
    overflow: hidden;
    clear: both;
}

#previous {
    float: left;
}

#next {
    float: right;
}

.footer-container-calendar {
    margin-top: 1em;
    border-top: 1px solid #dadada;
    padding: 10px 0;
}

.footer-container-calendar select {
    cursor: pointer;
    display: inline-block;
    zoom: 1;
    background: #ffffff;
    color: #585858;
    border: 1px solid #bfc5c5;
    border-radius: 3px;
    padding: 5px 1em;
}

3. Finally, add the following JavaScript code to functionalize the calendar.

function generate_year_range[start, end] {
    var years = "";
    for [var year = start; year  daysInMonth[month, year]] {
                break;
            } else {
                cell = document.createElement["td"];
                cell.setAttribute["data-date", date];
                cell.setAttribute["data-month", month + 1];
                cell.setAttribute["data-year", year];
                cell.setAttribute["data-month_name", months[month]];
                cell.className = "date-picker";
                cell.innerHTML = "" + date + "";

                if [ date === today.getDate[] && year === today.getFullYear[] && month === today.getMonth[] ] {
                    cell.className = "date-picker selected";
                }
                row.appendChild[cell];
                date++;
            }


        }

        tbl.appendChild[row];
    }

}

function daysInMonth[iMonth, iYear] {
    return 32 - new Date[iYear, iMonth, 32].getDate[];
}
