微信小程序动态设置央视

微信小程序动态设置央视,第1张

一、wx.setNavigationBarTitle

1.设置整个小程序通用标题,在app.json里设置:

"window": {

"navigationBarTitleText": "默认标题"

}

复制

2.单独设置页面标题,在对应页面json文件里设置(子页面设置会覆盖通用设置):

{

"navigationBarTitleText": "首页"

}

复制

3.动态设置,比如说:我们从接口拿到商品名称后,把商品名称设置到标题上

wx.request({

url: "请求接口url",

method: "POST",

data: {},

success: function (res) {

if (res.data.code == 200) {

// 修改navigationBarTitleText

wx.setNavigationBarTitle({

title: goods_name

})

}

}

})

复制

tips:动态设置 >页面独立设置 >通用设置

效果图:

当然,另外我们可以通过点击事件来动态设置标题:

test: function () {

wx.setNavigationBarTitle({

title: "我是点击后的标题"

})

}

复制

效果图:

二、wx.setNavigationBarColor

设置页面导航条颜色

wx.setNavigationBarColor({

frontColor: '#ffffff',

backgroundColor: '#ff0000',

animation: {

duration: 400,

timingFunc: 'easeIn'

}

})

复制

frontColor:前景颜色值,包括按钮、标题、状态栏的颜色,仅支持 #ffffff 和 #000000

backgroundColor:背景颜色值,有效值为十六进制颜色

animation:动画效果

①animation的结构包括:duration,timingFunc;

②timingFunc:linear(动画从头到尾的速度是相同的),easeIn(动画以低速开始),easeOut(动画以低速结束),easeInOut(动画以低速开始和结束)

效果图:

三、wx.showNavigationBarLoading和wx.hideNavigationBarLoading

wx.showNavigationBarLoading:在当前页面显示导航条加载动画

wx.hideNavigationBarLoading:在当前页面隐藏导航条加载动画

index.wxml

<button bindtap="showLoading">显示加载动画</button>

<button bindtap="hideLoading">隐藏加载动画</button>

复制

index.js

// 显示加载动画

showLoading: function () {

wx.showNavigationBarLoading()

},

// 隐藏加载动画

hideLoading: function () {

wx.hideNavigationBarLoading()

}

复制

效果图:

四、wx.hideHomeButton

隐藏返回首页按钮。微信7.0.7版本起,当用户打开的小程序最底层页面是非首页时,默认展示“返回首页”按钮,开发者可在页面 onShow 中调用 hideHomeButton 进行隐藏。

问题描述:

我们修的汇编语言是JAVA,怎奈自己学术不精.现在此象高手请教.小程序是期末做课程设计用的.题目有日历记事本,学籍管理系统,计算器,画图程序.其他的也可以.现需要两个程序,谢谢大家!
