移动端软键盘收起监听

watchKeybord() {
    let me = this
    let oriWinHeight = window.innerHeight
    window.onresize = function() {
        me.isKeybordAvail = true
        let newHeight = window.innerHeight

        // 阀值大于140判断为键盘收起
        if (newHeight - oriWinHeight > 140) {
            me.oprNum(‘input‘)
        }
        oriWinHeight = newHeight
    }
}        

setTimeout(function() {
    // 判断是否可用resize监听
    if (me.isKeybordAvail) {
        return
    }
    if (!newValue) {
        me.oprNum(‘input‘)
    }
