The vue method passes in multiple parameters

When using Vue, you often need to use methods to pass in multiple parameters to achieve a specific function. This article will introduce two common ways to pass in multiple parameters.

1. Passing parameters in array form

Vue's method parameter passing supports passing parameters in array form, that is, placing the parameters in an array in order, and then using destructuring syntax to retrieve the parameters in the method . The following is a simple example:

methods: {
  handleEvent(args) {
    const [arg1, arg2] = args;
    console.log(arg1, arg2);
  }
},

When calling this method, you can pass in an array containing multiple parameters to pass parameters:

<button @click="handleEvent(['Hello', 'Vue'])">Click me!</button>

Use destructuring syntax in the method, Parse the incoming parameters in sequence to achieve the purpose of passing in multiple parameters.

2. Use object form to pass parameters

In addition to using array form to pass parameters, Vue also supports using object form to pass parameters, that is, packaging multiple parameters in an object, and then in the method Use object destructuring syntax to extract each parameter. The following is an example:

methods: {
  handleEvent({ arg1, arg2 }) {
    console.log(arg1, arg2);
  }
}

When calling this method, you can pass in an object containing multiple parameters to achieve parameter passing:

<button @click="handleEvent({ arg1: 'Hello', arg2: 'Vue' })">Click me!</button>

Use object destructuring syntax in the method to The incoming parameters are parsed out in sequence, thereby achieving the purpose of passing in multiple parameters.

Summary

The above introduces two common ways to pass parameters in Vue methods, namely using array form to pass parameters and using object form to pass parameters. Both methods can achieve the purpose of passing in multiple parameters, and developers can choose the appropriate method according to their needs. Of course, when using these methods, you also need to pay attention to the use of deconstructing grammar to avoid grammatical errors.
