How to call multiple functions with @click in vue?

Question:

How to call multiple functions in a single @click? (aka v-on:click)?

I tried

  • Split functions with a semicolon: <div @click="fn1('foo');fn2('bar')"> </div>;

  • Use several @click: <div @click="fn1('foo')" @click="fn2('bar')"> </div>;

but how to do it properly?

P.S.: For sure I always can do

<div v-on:click="fn3('foo', 'bar')"> </div>

function fn3 (args) { 
  fn1(args);
  fn2(args);
}

But sometimes this isn't nice.

On Vue 2.3 and above you can do this:

<div v-on:click="firstFunction(); secondFunction();"></div>
// or
<div @click="firstFunction(); secondFunction();"></div>
Answer

First of all you can use the short notation @click instead of v-on:click for readability purposes.

Second You can use a click event handler that calls other functions/methods as @Tushar mentioned in his comment above, so you end up with something like this :

<div id="app">
   <div @click="handler('foo','bar')">
       Hi, click me!
   </div>
</div>

<!-- link to vue.js !--> 
<script src="vue.js"></script>

<script>
   (function(){
        var vm = new Vue({
            el:'#app',
            methods:{
                method1:function(arg){
                    console.log('method1: ',arg);
                },
                method2:function(arg){
                    console.log('method2: ',arg);
                },
                handler:function(arg1,arg2){
                    this.method1(arg1);
                    this.method2(arg2);
                }
            }
        })
    }()); 
</script>
Answer

to add an anomymous function to do that may be an alternative:

<div v-on:click="return function() { fn1('foo');fn2('bar'); }()"> </div> 
Answer

Separate into pieces.

Inline:

<div @click="f1() + f2()"></div> 

OR: Through a composite function:

<div @click="f3()"></div> 

<script>
var app = new Vue({
  // ...
  methods: {
    f3: function() { f1() + f2(); }
    f1: function() {},
    f2: function() {}
  }
})
</script>
Answer

This simple way to do v-on:click="firstFunction(); secondFunction();"

Answer

This works for me when you need to open another dialog box by clicking a button inside a dialogue box and also close this one. Pass the values as params with a comma separator.

<v-btn absolute fab small slot="activator" top right color="primary" @click="(addTime = true),(ticketExpenseList = false)"><v-icon>add</v-icon></v-btn>
Answer

If you want something a little bit more readable, you can try this:

<button @click="[click1($event), click2($event)]">
  Multiple
</button>

To me, this solution feels more Vue-like hope you enjoy

Answer

in Vue 2.5.1 for button works

 <button @click="firstFunction(); secondFunction();">Ok</button>
Answer

The Vue event handling only allows for single function calls. If you need to do multiple ones you can either do a wrapper that includes both:

<div @click="handler"></div>
////////////////////////////
handler: function() { //Syntax assuming its in the 'methods' option of Vue instance
    fn1('foo');
    fn2('bar');
}

EDIT

Another option is to edit the first handler to have a callback and pass the second in.

<div @click="fn1('foo', fn2)"></div>
////////////////////////////////////
fn1: function(value, callback) {
    console.log(value);
    callback('bar');
},
fn2: function(value) {
    console.log(value);
}

Html:

<div id="example">
  <button v-on:click="multiple">Multiple</button>
</div>

JS:

var vm = new Vue({
  el: '#example',
  data: {
    name: 'Vue.js'
  },
  // define methods under the `methods` object
  methods: {
    multiple: function (event) {
      this.first()
      this.second()
    }
    first:  function (event) {
      //yourstuff
    }
    second: function (event) {
      //yourstuff
    }
  }
})

vm.multiple()
Answer

I'd add, that you can also use this to call multiple emits or methods or both together by separating with ; semicolon

  @click="method1(); $emit('emit1'); $emit('emit2');"
Answer

you can, however, do something like this :

<div onclick="return function()
              {console.log('yaay, another onclick event!')}()" 
              @click="defaultFunction"></div>

yes, by using native onclick html event.
