this.$nextTick(() => {}是Vue.js中的一个方法,它在DOM更新之后执行回调函数。具体来说,它会在下次DOM更新循环结束之后执行传入的回调函数。这个方法常用于在修改DOM后,需要执行一些与DOM有关的操作,比如获取焦点、修改样式等。在提供的代码片段中,this.$nextTick()被用于确保在修改DOM元素后再执行相关的操作。在第一个代码片段中,changeColor()方法中的this.$nextTick()用于在修改完this.myid后,判断并修改相应的DOM元素的类名。在第二个代码片段中,getedit()方法中的this.$nextTick()用于在修改完this.isDisabled后,将焦点聚焦到input元素上。通过将操作放入this.$nextTick()中,可以确保这些操作在下次DOM更新循环结束后执行,以避免出现操作不准确或无效的情况。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
