| | | * input 输入框 |
| | | * @description 此组件为一个输入框,默认没有边框和样式,是专门为配合表单组件u-form而设计的,利用它可以快速实现表单验证,输入内容,下拉选择等功能。 |
| | | * @tutorial http://uviewui.com/components/input.html |
| | | * @property {String} type 模式选择,见官网说明 |
| | | * @property {Boolean} clearable 是否显示右侧的清除图标(默认true) |
| | | * @property {} v-model 用于双向绑定输入框的值 |
| | | * @property {String} input-align 输入框文字的对齐方式(默认left) |
| | | * @property {String} placeholder placeholder显示值(默认 '请输入内容') |
| | | * @property {Boolean} disabled 是否禁用输入框(默认false) |
| | | * @property {String Number} maxlength 输入框的最大可输入长度(默认140) |
| | | * @property {String Number} selection-start 光标起始位置,自动聚焦时有效,需与selection-end搭配使用(默认-1) |
| | | * @property {String Number} maxlength 光标结束位置,自动聚焦时有效,需与selection-start搭配使用(默认-1) |
| | | * @property {String Number} cursor-spacing 指定光标与键盘的距离,单位px(默认0) |
| | | * @property {String} placeholderStyle placeholder的样式,字符串形式,如"color: red;"(默认 "color: #c0c4cc;") |
| | | * @property {String} confirm-type 设置键盘右下角按钮的文字,仅在type为text时生效(默认done) |
| | | * @property {Object} custom-style 自定义输入框的样式,对象形式 |
| | | * @property {Boolean} focus 是否自动获得焦点(默认false) |
| | | * @property {Boolean} fixed 如果type为textarea,且在一个"position:fixed"的区域,需要指明为true(默认false) |
| | | * @property {Boolean} password-icon type为password时,是否显示右侧的密码查看图标(默认true) |
| | | * @property {Boolean} border 是否显示边框(默认false) |
| | | * @property {String} border-color 输入框的边框颜色(默认#dcdfe6) |
| | | * @property {Boolean} auto-height 是否自动增高输入区域,type为textarea时有效(默认true) |
| | | * @property {String Number} height 高度,单位rpx(text类型时为70,textarea时为100) |
| | | * @example <u-input v-model="value" :type="type" :border="border" /> |
