1、绑定class,v-bind:class 简写为::class
对象方式:
<!-- 绑定一个class对象,也可以绑定data中的对象--> <span v-bind:class="{orange:isorange, green:isgreen}">abc</span> <span v-bind:class="colors">def</span>
data: { isorange: true, isgreen: false, colors: { ‘orange‘: false, ‘green‘: true } }
数组方式:
<span v-bind:class="[orangecolor, big]">abc</span> <span v-bind:class="[big,colors]">def</span>
data: { big: "big", orangecolor: "orange", colors: { ‘orange‘: false, ‘green‘: true } }
2、绑定style , v-bind:style 简写为: :style
对象方式:
<span v-bind:style="{color:yellowcolor,fontSize:larger}">def</span><span v-bind:style="fontsizes">def</span>
data: { larger: "30px", yellowcolor: "yellow", fontsizes: { ‘fontSize‘: ‘40px‘ } }
数组方式:
<span v-bind:style="[fontsizes,colorstyle]">sss</span>
data: { fontsizes: { ‘fontSize‘: ‘40px‘ }, colorstyle: { ‘color‘: ‘orange‘ } }
3、注意在data中写style样式的时候,CSS 属性名可以用驼峰式(camelCase)或短横分隔命名(kebab-case)。
整体的例子如下:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <script src="vue.js"></script> <style> .orange { color: orange } .green { color: green } .big { font-size: larger; } </style> </head> <body> <div id="app"> <!-- 绑定一个class对象,也可以绑定data中的对象--> <span v-bind:class="{orange:isorange, green:isgreen}">abc</span> <span v-bind:class="colors">def</span> <span v-bind:class="[orangecolor, big]">abc</span> <span v-bind:class="[big,colors]">def</span> <!-- 绑定一个style对象,也可以绑定data中的对象--> <span v-bind:style="{color:yellowcolor,fontSize:larger}">def</span> <span v-bind:style="fontsizes">def</span> <!--数组语法--> <span v-bind:style="[fontsizes,colorstyle]">sss</span> </div> </body> <script type="text/javascript"> var app1 = new Vue({ el: "#app", data: { isorange: true, isgreen: false, big: "big", larger: "30px", orangecolor: "orange", yellowcolor: "yellow", colors: { ‘orange‘: false, ‘green‘: true }, fontsizes: { ‘fontSize‘: ‘40px‘ }, colorstyle: { ‘color‘: ‘orange‘ } }, methods: { } }); </script> </html>
