基于vue实现多引擎搜索及关键字提示(2)

listenWords: function(event) { console.log("listen keyup"); var that = this; var searchInput = document.getElementById("searchData"); event = window.event || event; if (event.keyCode == 13) { // enter event.preventDefault(); that.gotoSearch(); } if (event.keyCode == 8) { // backspace console.log(searchInput.value.length); if(searchInput.value.length == 0){ searchInput.blur(); searchInput.focus(); } } },

如有更好的方式欢迎讨论。
