感觉2.0好坑啊，自定义指令和1.0完全不一样，并且文档写得也不太清晰，下面是我写得一个demo,希望帮助大家更好地理解自定义指令

window.onload = function() {
// 全局指令
Vue.directive('demo',{
bind:function(el,val){
el.style.color = val.value.color
}
});
Vue.directive('focus',{
inserted: function(el,val) {
el.focus()
}
});
// 局部指令
var app = new Vue({
el: '#box',
directives: {
demo: {
bind: function(el, val) {
el.style.color = val.value.color
}
},
focus: {
inserted: function(el,val) {
el.focus()
}
}
}
});
}
