vue10-class陣列樣式繫結

首先看程式碼

<!DOCTYPE html>
<html lang=en>

<head>
    <meta charset="utf-8" />
    <title>Hello world</title>
    <script src="vue.js"></script>
    <style>
        .activated {
            color: red;
        }

        .activated-one {
            font-size: 50px;
        }
    </style>
</head>

<body>
    <div id="root">

        <!--class陣列繫結 後面加一個數組,可以寫多個值,陣列的值會被vue中的值代替 -->
        <div @click="handleDivClick" :class="[activated,activatedOne]">HelloWorld</div>
    </div>


    <script>
        var vm = new Vue({
            el: "#root",
            data: {
                activated: "",
                activatedOne: "activated-one"
            },
            methods: {
                handleDivClick: function () {
                    if (this.activated === "activated") {
                        this.activated = "";
                    } else {
                        this.activated = "activated";
                    }
                }
            }
        })

    </script>
</body>

</html>

vue繫結class屬性,後面跟著要給陣列,陣列的值就是vue例項中變數的值,把樣式的名稱賦值給變數,渲染後就賦給了class屬性。
