How to use jquery quotes

When using jQuery, the use of quotation marks is crucial. There are two types of quotes in jQuery: single quotes and double quotes. Which type to use mainly depends on personal preference and the requirements of the code itself.

Be aware of the following when using single and double quotation marks:

1. jQuery statements must use one type of quotation marks to contain parameters and parameter values. For example:

$('button').click(function() {
    alert('Hello, world!'); // 使用单引号
});

$('button').click(function() {
    alert("Hello, world!"); // 使用双引号
});

2. When a string enclosed within quotes itself contains quotes, a different type of quote must be used to enclose the string. For example:

$('h1').text("It's a beautiful day!"); // 使用双引号
$("#quote").text('"The future belongs to those who believe in the beauty of their dreams."'); // 使用双引号和单引号

3. If you include JSON data in a code block, it is recommended to use double quotes. For example:

var myData = {
    "name": "John",
    "age": 25,
    "city": "New York"
};

4. If you need to use string interpolation, it is usually recommended to use backticks. For example:

var name = "John";
var age = 25;
console.log(`My name is ${name}, and I'm ${age} years old.`); // 使用反引号

In summary, when using jQuery, you should choose single quotes, double quotes, or backticks based on your code and personal preference, but always maintain consistency.
