1.直接写监听

mounted() {//监听键盘Esc按键事件this.$nextTick(function() {// 按下键盘document.addEventListener('keydown', function(e) {// Esc按键是27 if (e.keyCode == 27) {//在这里写你的操作逻辑console.log("打印了");}});});}

2.将监听内容封装到方法里

created() {window.addEventListener("keyup", this.enterSearch)},methods:{enterSearch: function(e) {//监听回车if (e.keyCode === 13) {//在这里写你的操作逻辑//this.adduser()}},}
