插件可以满足常用的提示显示,支持12个方向,支持边框、背景色、文本颜色自定义,支持位置微调、层级微调、宽度间距等参数调整。
先看看效果:
tips:提示信息组件
参数:
- msg:'asdf',内容
- dire:2,方向
- w:250,宽度
- _x:0,横向偏移
- _y:0,纵向偏移
- zIndex:100000,层级
- borderColor:#FFF,边框颜色
- bgColor:#FFF,背景颜色
- useHover:true是否使用悬浮显示
- color:默认提示文字颜色
- padding:边距
javascript代码:

CSS:
.tip-wrap { position: absolute; display: none; } .tip-arr-a, .tip-arr-b { position: absolute; width: 0; height: 0; line-height: 0; border-style: dashed; border-color: transparent; } page: <div class="test"> <span data-tip-msg="我是测试数据<br>我是测试数据<br>我是测试数据">我是测试数据</span> </div> <script> $('.test span').tips(); </script>
