Below I will share with you an implementation method of vue full selection and inverse selection (no bugs, novices can read it), which has a good reference value and I hope it will be helpful to everyone.
I won’t say any more nonsense and let’s get straight to the code!
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<p id="app">
<p style="padding-left: 20px">
<ul style="margin-bottom: 20px">
<li v-for="(item, index) in proData">
<input type="checkbox" :value="index" v-model="selectArr">{{item.name}}
</li>
</ul>
<label>
<input type="checkbox" @click="selectAll" :checked="checked"/>全选
</label>
</p>
</p>
</body>
<script src="https://cdn.jsdelivr.net/npm/vue"></script>
<script type="text/javascript">
var vm = new Vue({
el : "#app",
data : {
proData: [
{
"name": "张三"
}, {
"name": "李四"
}, {
"name": "王五"
}, {
"name": "赵六"
}
],
selectArr: [],
checked : false
},
watch : {
selectArr(curVal){
if(curVal.length == this.proData.length){
this.checked = true
}else{
this.checked = false
}
}
},
methods: {
selectAll(event){
if (!event.currentTarget.checked) {
this.selectArr = [];
} else { //实现全选
this.selectArr = [];
this.proData.forEach((item, i) =>{
this.selectArr.push(i);
});
}
}
}
})
</script>
</html>The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
