在监听键盘事件时,我们经常需要检查常见的键值。Vue 允许为 v-on 在监听键盘事件时添加按键修饰符:

 

JS部分:

复制代码
 1     Vue.config.keyCodes = {  2 f2:113,  3  }  4 var app = new Vue({  5 el: "#app",  6  data() {  7 return {  8 msg: "我是谁,我从哪里来,我又要往哪里去"  9  } 10  }, 11  methods:{ 12  submit(){ 13 console.log("你按了回车键"); 14  }, 15  f2submit(){ 16 console.log("你按了f2键"); 17  } 18  } 19 });
复制代码

 

HTML部分:

1     <div id="app"> 2 <p><input type="text" placeholder="回车可提交" @keyup.enter="submit"></p> 3 <p><input type="text" placeholder="f2可提交" @keyup.f2="f2submit"></p> 4 </div>

 

结果:

Vue内置的按键名:

  • .enter
  • .tab
  • .delete (捕获“删除”和“退格”键)
  • .esc
  • .space
  • .up
  • .down
  • .left
  • .right
