记录一下uniapp输入框input的@input事件失效问题

今天开发中遇到一个Bug,input的&＃64;input事件竟然时而触发时而失效&＃xff0c;先来看看我的代码&＃xff1a;
HTML:

<input&＃64;input&＃61;"changeNumber"type&＃61;"number"v-model&＃61;"orderForm.number"placeholder&＃61;"请输入1 &＃xff5e; 99的整数"
/>


JS&＃xff1a;修改前

changeNumber(e) {let num &＃61; Number(e.detail.value);if (num &＃61;&＃61;&＃61; 0 || num &＃61;&＃61;&＃61; "") {num &＃61; 1;}if (num < 0) {num &＃61; 1;}if (num > 99) {num &＃61; 99;}this.orderForm.number &＃61; num.toFixed(0);},


JS&＃xff1a;修改后 解决BUg

changeNumber(e) {let num &＃61; Number(e.detail.value);if (num &＃61;&＃61;&＃61; 0 || num &＃61;&＃61;&＃61; "") {num &＃61; 1;}if (num < 0) {num &＃61; 1;}if (num > 99) {num &＃61; 99;}setTimeout(() &＃61;> { this.orderForm.number &＃61; num.toFixed(0) }, 0)},


这个BUg很奇怪&＃xff0c;直接赋值属于同步&＃xff0c;加了定时器就变成异步赋值了&＃xff0c;具体原因不明确&＃xff0c;个人猜测是因为同步赋值没有改变视图层&＃xff0c;异步赋值视图层会刷新&＃xff0c;个人愚见&＃xff0c;有知道原因的大佬欢迎在下面留言纠正&＃xff1b;
