How to get selected value of DatePicker in JavaScript?
The DatePicker control is commonly used in web development to allow users to select a specific date from a calendar. Once a date is selected, it becomes important to retrieve the selected value for further processing. In JavaScript, you can easily accomplish this task with a few lines of code. Let’s explore how to get the selected value of a DatePicker in JavaScript.
To begin with, make sure you have included the necessary JavaScript libraries to use the DatePicker control. One popular library for this purpose is jQuery UI, which provides a wide range of user interface components, including the DatePicker.
Next, create a DatePicker control in your HTML markup. Give it a unique ID so that you can easily reference it in your JavaScript code:
“`html
“`
Now, let’s dive into the JavaScript code to retrieve the selected value from the DatePicker:
“`javascript
// Retrieve the selected value from the DatePicker
var selectedDate = $(“#datepicker”).datepicker(“getDate”);
// Convert the selected value to a desired format
var formattedDate = $.datepicker.formatDate(“dd-mm-yy”, selectedDate);
// Display the formatted selected value
console.log(“Selected Date: ” + formattedDate);
“`
In the code snippet above, we first use the jQuery selector `$(“#datepicker”)` to target the DatePicker control using its unique ID. Then, we call the `datepicker()` function with the `”getDate”` parameter to obtain the selected date. This function returns a JavaScript Date object representing the selected value.
Next, we use the `$.datepicker.formatDate()` method to format the selected date according to our desired format. In this example, the format is set to `”dd-mm-yy”` which represents day-month-year. Feel free to adjust the format as per your requirements.
Finally, we log the formatted selected value to the console. You can replace this step with any desired action, such as displaying the value in a specific element on your webpage.
