Vue judges whether a string starts with a certain string

You can use the startsWith() method to determine whether a string starts with another string. This method is part of ES6 and can be used in the following ways:

let str = 'Hello World';

if (str.startsWith('Hello')) {
  console.log('字符串以Hello开头');
} else {
  console.log('字符串不以Hello开头');
}

This will output a string starting with Hello.

If the string you need to check is longer, you can store it in a variable like this:

let str1 = 'Hello World';
let str2 = 'Hello';

if (str1.startsWith(str2)) {
  console.log('字符串以Hello开头');
} else {
  console.log('字符串不以Hello开头');
}

This will output "String starts with Hello" to the console.
