class&style style setting

class

html code

<p id="box">
    <strong>阿斯顿发</strong>
</p>
Copy after login

css code

.red {
    color: red;
}
.gray {
    background-color: gray;
}
Copy after login

js code

window.onload = function() {
    new Vue({
        el: '#box',
        data: {
            red: 'red',
            gray: 'gray'
        }
    });
}
Copy after login

How to write the style to take effect

  1. :class="[red, gray]" The data attribute in the vue parameter is called

    <strong :class="[red, gray]"></strong>
    Copy after login
  2. :class="{red : true, gray: true}"

    <strong :class="{red: true, gray: true}"></strong>
    Copy after login

    The second method can also call the data attribute of the vue parameter. Remember, everything in Vue is data

    new Vue({
        el: '#box',
        data: {
           red: 'red',
           gray: 'gray',
           a: true,
           b: false
     }   
    });
    Copy after login
    <strong :class="{red: a, gray: b}"></strong>
    Copy after login
  3. :class="json", a simplified version of the second method, the official version

    new Vue({
        el: '#box',
        data: {
            red: 'red',
            gray: 'gray',
            json: {
                a: true,
                b: false
            }
        }
    });
    Copy after login
<strong :class="json"></strong>
Copy after login

style

is basically the same as class

  1. :style="{}"

<strong :style="{color: &#39;red&#39;, backgroundColor: &#39;gray&#39;}"></strong>
Copy after login
  1. :style="a"

    new Vue({
        el: '#box',
        data: {
            red: 'red',
            gray: 'gray',
            a: {
                color: 'red',
                backgroundColor: 'gray' //注意复合样式的书写规范
            }
        }
    });
    Copy after login
    <strong :style="a">阿斯顿发</strong>
    Copy after login
  2. :style="[a, b]", a, b correspond to the two json data in data
