今天来介绍一下slider(滑动选择器):
官方文档:https://mp.weixin.qq.com/debug/wxadoc/dev/component/slider.html
1.效果图如下,
2.index.js中:
//index.js
//获取应用实例
const app = getApp()
var that;
var isDisabled = true;
Page({
data: {
//默认最小值20;
min: 20,
//默认最大值20;
max: 100,
//设置不禁用
disabled: false,
//设置选中默认颜色
colorSelect: '#00ff00',
//设置背景颜色
backgroundColor: "#ccc",
//设置滑块的大小
blockSize: 28,
//设置滑块的颜色
blockColor: "#eeeeee",
//是否显示当前 value
showValue: true,
//步长
step: 5,
},
onLoad: function () {
that = this;
},
//设置最小值
minInput: function (e) {
that.setData({
min: e.detail.value,
})
},
//设置最大值
maxInput: function (e) {
that.setData({
max: e.detail.value,
})
},
//设置是否禁用滑动
btnDisabled: function (e) {
if (isDisabled == true) {
isDisabled = false;
that.setData({
disabled: true,
})
} else {
isDisabled = true;
that.setData({
disabled: false,
})
}
},
//已选择的颜色
colorSelectInput: function (e) {
that.setData({
colorSelect: e.detail.value,
})
},
//设置背景条的颜色
bgColorInput: function (e) {
that.setData({
backgroundColor: e.detail.value,
})
},
//设置滑块的大小
blockSizeInput: function (e) {
that.setData({
blockSize: e.detail.value,
})
},
//设置步长,取值必须大于 0,并且可被(max - min)整除
stepInput: function (e) {
that.setData({
step: e.detail.value,
})
},
//设置滑块的颜色
blockColorInput: function (e) {
that.setData({
blockColor: e.detail.value,
})
},
//设置是否显示当前value
btnshowValue: function () {
that.setData({
showValue: false,
})
},
//完成一次拖动后触发的事件
sliderchange: function (e) {
wx.showToast({
title: "拖动后触发" + e.detail.value,
duration: 1000
})
},
//拖动过程中的触发的事件
bindchanging: function (e) {
wx.showToast({
title: "拖动中触发" + e.detail.value,
duration: 1000
})
},
})
3.index.wxss中:
/*输入框样式 */
.section {
width: 93%;
margin: 20rpx;
background-color: #ccc;
padding: 10rpx;
font-size: 30rpx;
border-radius: 5px;
}
/*button样式 */
.button {
width: 95%;
margin: 20rpx;
}
4.index.wxml中:
<view class="section_gap">
<text class="section__title">使用示例:</text>
<view class="body-view">
<slider bindchange="sliderchange" bindchanging="bindchanging" min="{{min}}" max="{{max}}" disabled="{{disabled}}" activeColor='{{colorSelect}}' backgroundColor='{{backgroundColor}}' block-size='{{blockSize}}' block-color='{{blockColor}}' step="{{step}}" show-value='{{showValue}}'/>
</view>
</view>
<view class="section">
<input placeholder="设置最小值,默认为20" type="number" bindinput="minInput" confirm-type="done" focus/>
</view>
<view class="section">
<input placeholder="设置最大值,默认为100" type="number" bindinput="maxInput" confirm-type="done" focus/>
</view>
<view>
<view class='text'>设置已选择的颜色(请使用十六进制颜色值,例如:#ff00ff)</view>
<input class="section" placeholder="" value="#" bindinput="colorSelectInput" confirm-type="done" focus/>
</view>
<view>
<view class='text'>设置背景条的颜色(请使用十六进制颜色值,例如:#ff00ff)</view>
<input class="section" placeholder="" value="#" bindinput="bgColorInput" confirm-type="done" focus/>
</view>
<view>
<view class='text'>设置滑块的颜色(请使用十六进制颜色值,例如:#ff00ff)</view>
<input class="section" placeholder="" value="#" bindinput="blockColorInput" confirm-type="done" focus/>
</view>
<view class="section">
<input placeholder="设置滑块的大小,取值范围为12 - 28" type="number" bindinput="blockSizeInput" confirm-type="done" focus/>
</view>
<view class="section">
<input placeholder="步长,取值必须大于 0,并且可被(max - min)整除" type="number" bindinput="stepInput" confirm-type="done" focus/>
</view>
<button class='button' catchtap='btnDisabled'>设置/取消禁用</button>
<button class='button' catchtap='btnshowValue'>隐藏当前value</button>
