Convert js object to jquery

With the continuous development of front-end development, JavaScript and jQuery have become the two most commonly used programming languages ​​​​in front-end development. Although the syntax of the two is different, they can both be used to create and manipulate objects. In actual development, it is often necessary to convert JavaScript objects into jQuery objects in order to more conveniently use some functions provided by jQuery. This article will introduce how to convert JavaScript objects into jQuery objects.

1. Using the $() function

In jQuery, the $() function is the most basic selector. By using this function, we can convert JavaScript objects into jQuery objects. For example, if we have a JavaScript object:

let obj = {
  name: "Tom",
  age: 18,
  gender: "male"
};

We can use the $() function to convert it to a jQuery object:

let $obj = $(obj);

In this example, we have the JavaScript object as $() function parameters. The $() function will wrap the object into a jQuery object and return it. Now, $obj is a jQuery object in which we can use some of the functions provided by jQuery.

2. Using the $.extend() function

Another way to convert a JavaScript object into a jQuery object is to use the $.extend() function. This function is used to merge two or more objects. By passing an empty jQuery object and a JavaScript object as arguments to this function, we can convert the JavaScript object into a jQuery object. The sample code is as follows:

let obj = {
  name: "Tom",
  age: 18,
  gender: "male"
};

let $obj = $.extend({}, obj);

In this example, we first create a JavaScript object obj, and then pass it as the second parameter to the $.extend() function. The first parameter of this function is an empty object used to represent the target object of the merged result. In this way, we can convert JavaScript objects into jQuery objects.

3. Use the $.parseJSON() function

If your JavaScript object is JSON format data returned from the server, you can use the $.parseJSON() function to Convert it to jQuery object. This function is used to parse a JSON string into a JavaScript object and then wrap it into a jQuery object. The sample code is as follows:

let jsonStr = '{"name":"Tom", "age":18, "gender":"male"}';

let $obj = $.parseJSON(jsonStr);

In this example, we pass a JSON string as a parameter of the $.parseJSON() function and save its return value as a jQuery object. In this way, we convert the JavaScript object into a jQuery object.

Summary:

This article introduces three methods of converting JavaScript objects into jQuery objects. Using the $() function is the most common method, and the $.extend() function and $.parseJSON() function can also complete this task well. No matter which method you use, you can more conveniently use some of the functions provided by jQuery. Hope this article can be helpful to you.
