进度条
progress
可应用于许多业务场景,如任务完成进度、loading 等等。
示例
<div class="layui-progress"> <div class="layui-progress-bar" lay-percent="30%"></div> </div> <hr class="ws-space-16"> <div style="width:300px"> <div class="layui-progress"> <div class="layui-progress-bar" lay-percent="50%"></div> </div> </div> <!-- import layui -->
进度条宽度是 100% 适配于它的父级元素,如上面的进度条是在一个 300px 的父容器中。
进度条主题
<div class="layui-progress"> <div class="layui-progress-bar layui-bg-red" lay-percent="10%"></div> </div> <hr class="ws-space-16"> <div class="layui-progress"> <div class="layui-progress-bar layui-bg-orange" lay-percent="30%"></div> </div> <hr class="ws-space-16"> <div class="layui-progress"> <div class="layui-progress-bar layui-bg-primary" lay-percent="50%"></div> </div> <hr class="ws-space-16"> <div class="layui-progress"> <div class="layui-progress-bar layui-bg-blue" lay-percent="60%"></div> </div> <hr class="ws-space-16"> <div class="layui-progress"> <div class="layui-progress-bar" lay-percent="70%"></div> </div> <!-- import layui -->
大号进度条
通过对进度条容器追加 className
为 layui-progress-big
可设置大尺寸风格的进度条。
<div class="layui-progress layui-progress-big"> <div class="layui-progress-bar" lay-percent="15%"></div> </div> <hr class="ws-space-16"> <div class="layui-progress layui-progress-big"> <div class="layui-progress-bar layui-bg-orange" lay-percent="35%"></div> </div> <hr class="ws-space-16"> <div class="layui-progress layui-progress-big"> <div class="layui-progress-bar layui-bg-blue" lay-percent="75%"></div> </div> <!-- import layui -->
显示进度值
<div class="layui-progress" lay-showpercent="true"> <div class="layui-progress-bar" lay-percent="30%"></div> </div> <hr class="ws-space-16"> <div class="layui-progress" lay-showpercent="true"> <div class="layui-progress-bar" lay-percent="5 / 10"></div> </div> <hr class="ws-space-16"> <div class="layui-progress layui-progress-big" lay-showpercent="true"> <div class="layui-progress-bar" lay-percent="70%"></div> </div> <!-- import layui -->
API
API | 描述 |
---|---|
var element = layui.element | 获得 element 模块。 |
element.render('progress', filter) | 进度条 progress 组件渲染。 |
element.progress(filter, percent) | 设置进度值 |
渲染
element.render('progress', filter);
- 参数
'progress'
: 渲染进度条的固定值 - 参数
filter
: 对应进度条容器lay-filter
的属性值
在元素加载完毕后,element 模块会自动对元素进行一次渲染。而当元素为动态插入时,需通过该方法完成初始化渲染。
<div id="test"></div>
<!-- import layui -->
<script>
layui.use(function(){
var element = layui.element;
var $ = layui.$;
// 动态插入进度条元素
$('#test').html(`
<div class="layui-progress" lay-filter="demo-filter-progress">
<div class="layui-progress-bar" lay-percent="30%"></div>
</div>
`);
// 渲染进度条组件
element.render('progress', 'demo-filter-progress');
});
</script>
属性
属性 | 描述 |
---|---|
lay-percent | 用于设置进度条的值,进度条内层容器属性。支持 百分比 和 分数 形式。用法详见:#示例 |
lay-showpercent | 是否显示进度值,进度条外层容器属性,默认不显示。用法详见:#示例 |
设置进度值
element.progress(filter, percent);
- 参数
filter
: 对应进度条容器lay-filter
的属性值 - 参数
'percent'
: 进度条的值
该方法用于动态改变进度条的值。示例:
<div class="layui-progress layui-progress-big" lay-showPercent="true" lay-filter="demo-filter-progress"> <div class="layui-progress-bar" lay-percent="0%"></div> </div> <hr class="ws-space-16"> <div class="layui-btn-container"> <button class="layui-btn" lay-on="setPercent">设置 50%</button> <button class="layui-btn" lay-on="loading">模拟 loading</button> </div> <!-- import layui --> <script> layui.use(function(){ var element = layui.element; var util = layui.util; // 普通事件 util.on('lay-on', { // 设置进度值 setPercent: function(){ element.progress('demo-filter-progress', '50%'); // 设置 50% 的进度 }, // 模拟 loading loading: function(othis){ var DISABLED = 'layui-btn-disabled'; if(othis.hasClass(DISABLED)) return; var n = 0; var timer = setInterval(function(){ n = n + Math.random()*10|0; if(n>100){ n = 100; clearInterval(timer); othis.removeClass(DISABLED); } element.progress('demo-filter-progress', n+'%'); }, 300+Math.random()*1000); othis.addClass(DISABLED); } }); }); </script>
