uniapp input自动聚焦

input标签有一个属性focus：获取焦点。默认值false

<input :focus="firstFocus" type="text" value="" placeholder="请输入药品名称" />

初始化firstFocus为false

export default {
    data() {
        return {
            firstFocus:false,
        }
    },
}

在onload中修改焦点值

onLoad(options) {
    var that = this;
    that.firstFocus = false;
    setTimeout(function(){
        that.firstFocus = true;
    },500)
}
