| | | * icon 图标 |
| | | * @description 基于字体的图标集,包含了大多数常见场景的图标。 |
| | | * @tutorial https://www.uviewui.com/components/icon.html |
| | | * @property {String} name 图标名称,见示例图标集 |
| | | * @property {String} color 图标颜色,可接受主题色 (默认 color['u-content-color'] ) |
| | | * @property {String | Number} size 图标字体大小,单位px (默认 '16px' ) |
| | | * @property {Boolean} bold 是否显示粗体 (默认 false ) |
| | | * @property {String | Number} index 点击图标的时候传递事件出去的index(用于区分点击了哪一个) |
| | | * @property {String} hoverClass 图标按下去的样式类,用法同uni的view组件的hoverClass参数,详情见官网 |
| | | * @property {String} customPrefix 自定义扩展前缀,方便用户扩展自己的图标库 (默认 'uicon' ) |
| | | * @property {String | Number} label 图标右侧的label文字 |
| | | * @property {String} labelPos label相对于图标的位置,只能right或bottom (默认 'right' ) |
| | | * @property {String | Number} labelSize label字体大小,单位px (默认 '15px' ) |

| | | * @property {String | Number} space label与图标的距离,单位px (默认 '3px' ) |
| | | * @property {String} imgMode 图片的mode |
| | | * @property {String | Number} width 显示图片小图标时的宽度 |
| | | * @property {String | Number} height 显示图片小图标时的高度 |
| | | * @property {String | Number} top 图标在垂直方向上的定位 用于解决某些情况下,让图标垂直居中的用途 (默认 0 ) |
| | | * @property {Boolean} stop 是否阻止事件传播 (默认 false ) |
| | | * @property {Object} customStyle icon的样式,对象形式 |
| | | * @event {Function} click 点击图标时触发 |
| | | * @event {Function} touchstart 事件触摸时触发 |
| | | * @example <u-icon name="photo" color="#2979ff" size="28"></u-icon> |
