Answer 1

show(data) {

    let self = this;
    console.log("show(data)")
    self.page.setData({ 'isHide': true, 'content': data });
    setTimeout(function () {
        self.page.setData({ 'isHide': false })
    }, 2000)
}


self就没事了

Answer 2

searchInput: function(e){
    var value = e.detail.value;
    this.setData({
        confirm: (value ? true : false)
    });
}
