使用uview输入框 绑定了v-model 获取输入框的值,发现value值变化后触发了页面onshow，数字键盘异常消失，查看组件参数和事件后，想起对应解决办法 ,欢迎指教！

<template>
	<view>
	    <u-input v-model="value"  type="number" shape="circle" border="surround" placeholder="请输入金额"
				 @focus="inputfocus" @blur="unfocused"  :focus="firstFocus" @change='firstChange'/>
	</view>
</template>

<script>
	export default {
		data() {
			return {
				firstFocus:false,
                value: '',
			}
		},
		onShow() {
		    //调用fisrtChange
			this.firstChange()
		},
		methods: {
			firstChange() {
                // 如果input 绑定了value值 输入内容触发了onshow 会中断数字输入框
				// this.firstFocus = false; 
				setTimeout(() => {
					this.firstFocus = true; //自动获取焦点
				},0)
			},
            unfocused(){
				// 失焦后 聚焦状态改为false
				this.firstFocus = false
			},
		}
	}
</script>
