This is a simple vue demo:
<body>
<div id="app">
<ul>
<li v-for="text,i in todoList" v-on:click="method_1(i)" >{{text}}</li>
</ul>
<ul>
<li v-for="text,i in todoList" v-on:click="method_2" >{{text}}</li>
</ul>
<ul>
</ul>
</div>
<script src="https://cdn.bootcss.com/vue/2.5.16/vue.min.js"></script>
<script>
new Vue({
el:"#app",
data:{
todoList:["aaaaa",'bbbbbb','ccccc']
},
methods:{
method_1:function(i){
console.log(i) // i is index of v-for
},
method_2:function(e){
console.log(e)
},
}
})
</script>
</body>
I want to bind onclick function and put event and index from v-for as this function's params.
If I use v-on:click="method_1(i)":
-- vue will this take i is varibale of before;
eles if I use v-on:click="method_1 :
-- vue will automatlly take click event as params.
But I want both click event and variable of before as my function's params.How can I do that?

To use both events and params, you need to have something like example($event, params)
Using your example,
<li v-for="(text, i) in todoList" v-on:click="method_1($event, i)">
{{ text }}
</li>
methods: {
method_1: function(ev, i){
console.log(ev) // this is the event
console.log(i) // i is index of v-for
}
}
