书接上回。
一、开关选择器---switch

开关选择器小案例
text.wxml
<view class="page">
<view class="item">
声音<switch type="switch" checked bindchange="change" />
</view>
<view class="item">
震动<switch type="switch" bindchange="change" />
</view>
</view>
text.js
Page({
change:function(e){
console.log(e.detail.value)
//被选上的时候值为true
//没有被选上的时候值为false
//通过这个我们可以对其进行操作
}
})
text.wxss
.item{
background-color: #dfdfdf;
padding: 10px;
line-height: 30px;
border: 1px solid white;
}
switch{
float: right
}
运行效果

二、图标---组件:icon
微信提供了很多默认的图标,可以自行选择,那么列举一下、

图标案例
text.wxml
<view class="page">
<view>{{title}}</view>
<view wx:for="{{icons}}" class="center">
{{item.type}} <icon type="{{item.type}}" size="{{item.size}}"></icon>
</view>
<button>
<icon type="download"></icon>下载
</button>
</view>
text,js
Page({
data:{
title:"",
icons:[
{
type:"success" ,size:"25"
},
{
type:"success_no_circle" ,size:"25"
},
{
type:"info" ,size:"25"
},
{
type:"warn" ,size:"25"
},
{
type:"waiting" ,size:"25"
},
{
type:"cancel" ,size:"25"
},
{
type:"download" ,size:"25"
},
{
type:"search" ,size:"25"
},
{
type:"clear" ,size:"25"
},
]
},
text.css
button{
width: 150px;
margin-top: 10px;
}
icon{
position: relative;
top: 4px;
}
各种图标效果

三、页面 链接---组件:navigator

页面链接小案例
这里介绍两种链接的样式,一个是通过点击事件,一个是通过navigator组件
text.wxml
<view class="page">
<navigator url="/pages/demo7/demo7?title=form_demo8">跳转到demo7</navigator>
//通过点击的方式跳转
<view bindtap="redirect">跳转到demo6</view>
</view>
text.js
Page({
redirect:function(){
wx.navigateTo({
url: '/pages/demo6/demo6?title=from-demo8&a=1&b=2',
success: function(res){
// success
},
fail: function() {
// fail
},
complete: function() {
// complete
}
})
}
})
可以看到,我们在链接的后面传递了参数,所以在对应的页面需要接收参数,在上栗中我们要设置接收
那我们现在,通过传递的title来改变上栗中的title
Page({
data:{
title:"",
icons:[
{
type:"success" ,size:"25"
},
{
type:"success_no_circle" ,size:"25"
},
{
type:"info" ,size:"25"
},
{
type:"warn" ,size:"25"
},
{
type:"waiting" ,size:"25"
},
{
type:"cancel" ,size:"25"
},
{
type:"download" ,size:"25"
},
{
type:"search" ,size:"25"
},
{
type:"clear" ,size:"25"
},
]
},
onLoad:function(options){
this.setData({
//options以数组的形式拿到从上一个页面传递过来的所有参数
title:options.title
})
}
})
运行结果

四、音乐---组件:audio

音频小栗子
text.wxml
<view class="page">
<audio poster="{{poster}}" name="{{name}}" author="{{author}}" src="{{src}}"controls></audio>
