本文实例为大家分享了vue实现全选反选功能的具体代码,供大家参考,具体内容如下
<!DOCTYPE html>
<html lang="en">

<meta charset="UTF-8">
<title>Title</title>
</head>
<script type="text/javascript" src = "vue.js"></script>
<body>
<div id = "test">
<input type='checkbox' v-model="checkBox.checked" class='input-checkbox' @click='checkedAll'>全选
<div v-for='checkb in checkboxData'>
<input type='checkbox' class='input-checkbox' @click="checkItem" v-model='checkBox.items[checkb.id]'>
{{checkb.value}}
</div>
</div>
</body>
<script>
var vue = new Vue({
el:"#test",
data:{
checkboxData:[
{
id:'1',
value:'苹果'
},{

},
methods:{
checkedAll: function() {
var _this = this;
console.log(_this.checkboxData);
console.log(this.checkBox.items);
this.checkboxData.forEach(function (item) {
console.log(item.id);
_this.checkBox.items[item.id] = _this.checkBox.checked;
console.log(_this.checkBox.items);
});
//实现反选
},
checkItem:function(){
var unchecked = 0;
var _this = this;
this.checkboxData.forEach(
function(item) {
unchecked += (! _this.checkBox.items[item.id]) || 0;
});
_this.checkBox.checked = unchecked > 0 ? false : true;
}
}
})
