How to convert date to string in jquery
In front-end development, date processing is a very common task. However, when storing dates in the database or transmitting data, we often need to convert date objects into strings. This article will introduce how to use jQuery to convert a date object into a string.
1. Introduction to JavaScript date objects
Before learning how to convert dates into strings, we need to first understand the date objects in JavaScript. JavaScript date objects are used to represent time and date and can perform corresponding operations. The method to create a date object is very simple, just use the Date() constructor.
For example:
var date = new Date(); console.log(date); // 输出当前日期和时间
Here we not only create a date object, but also print the date object. This code will output the current date and time, such as: Tue Aug 31 2021 16:16:53 GMT 0800 (China Standard Time).
2. Convert date objects into strings
Next, we will introduce how to use jQuery to convert date objects into strings. jQuery provides a plug-in specifically for date formatting - jQuery UI Datepicker. We can convert the date object into a string using the plugin's dateFormat property.
var date = new Date();
var dateString = $.datepicker.formatDate('yy-mm-dd', date);
console.log(dateString); // 输出格式化后的日期字符串Here, we first create a date object, and then use the $.datepicker.formatDate method to convert the date object into a string, and we define the format of the string as 'yy-mm-dd'. Finally, we print the string to the console.
3. Parameter list for date formatting
In the above code, we saw the dateFormat attribute and set the format to ‘yy-mm-dd’. So, what are the optional values for this attribute? Let's introduce the formatting parameters supported by jQuery UI Datepicker:
| Parameter | Description |
|---|---|
| d | One day of the month (1-31) |
| dd | One day of the month (01- 31) |
| ddd | Abbreviation of the day of the week (for example: Monday, Tuesday, etc.) |
| dddd | The full name of the day of the week (for example: Monday, Tuesday, etc.) |
| m | Month (1-12) |
| mm | Month (01-12) |
| mmm | Abbreviation of month (for example: January, February, etc.) |
| mmmm | The full name of the month (for example: January, February, etc.) |
| yy | Year Two-digit representation (for example: 21, 22, etc.) |
| yyyy | Four-digit representation of the year (for example: 2021, 2022, etc.) |
| h | Hours (0-23) |
| hh | Hours (00-23) |
| H | Hours (0-12) |
| HH | Hours (00-12) |
| M | Minutes (0-59) |
| MM | Minutes (00-59) |
| s | Seconds (0-59) |
| ss | Seconds (00-59) |
| l or L | milliseconds (0-999) |
| t or T | AM or PM mark (e.g. : AM or PM) |
| z or zz or zzz | Time zone expression (for example: CST, GMT, etc.) |
4. Sample code
Finally, let’s look at a complete code example. The specific code is as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>jQuery日期转字符串</title>
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<link rel="stylesheet" href="https://code.jquery.com/ui/1.13.0/themes/smoothness/jquery-ui.css">
<script src="https://code.jquery.com/ui/1.13.0/jquery-ui.min.js"></script>
</head>
<body>
<div id="date"></div>
<script>
var date = new Date();
var dateString = $.datepicker.formatDate('yy-mm-dd', date);
$("#date").text(dateString); // 将日期字符串输出到div元素中
</script>
</body>
</html>We first introduced jQuery and jQueryUI resource files, and then used $ The .datepicker.formatDate method converts the date object into a string and sets the format of the string to 'yy-mm-dd'. Finally, we output the date string into a div element.
5. Summary
This article introduces how to use jQuery to convert JavaScript date objects into strings, and gives a list of date formatting parameters supported by jQuery UI Datepicker. For better understanding, we also provide a complete demo code for readers' reference.
Of course, jQuery's code is already very concise. If you use a framework in your project, the framework also has its own date processing library, which can process dates more conveniently.
