@description 借助此组件,可以实现表单的输入, 有"text"和"textarea"类型的,此外,借助uView的picker和actionSheet组件可以快速实现上拉菜单,时间,地区选择等, 为表单解决方案的利器。 * @tutorial https://www.uviewui.com/components/field.html * @property {String} type 输入框的类型(默认text) * @property {String} icon label左边的图标,限uView的图标名称 * @property {Object} icon-style 左边图标的样式,对象形式 * @property {Boolean} right-icon 输入框右边的图标名称,限uView的图标名称(默认false) * @property {Boolean} required 是否必填,左边您显示红色"*"号(默认false) * @property {String} label 输入框左边的文字提示 * @property {Boolean} password 是否密码输入方式(用点替换文字),type为text时有效(默认false) * @property {Boolean} clearable 是否显示右侧清空内容的图标控件(输入框有内容,且获得焦点时才显示),点击可清空输入框内容(默认true) * @property {Number String} label-width label的宽度,单位rpx(默认130) * @property {String} label-align label的文字对齐方式(默认left) * @property {Object} field-style 自定义输入框的样式,对象形式 * @property {Number | String} clear-size 清除图标的大小,单位rpx(默认30) * @property {String} input-align 输入框内容对齐方式(默认left) * @property {Boolean} border-bottom 是否显示field的下边框(默认true) * @property {Boolean} border-top 是否显示field的上边框(默认false) * @property {String} icon-color 左边通过icon配置的图标的颜色(默认#606266) * @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 Boolean} error-message 显示的错误提示内容,如果为空字符串或者false,则不显示错误信息 * @property {String} placeholder 输入框的提示文字 * @property {String} placeholder-style placeholder的样式(内联样式,字符串),如"color: #ddd" * @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} disabled 是否不可输入(默认false) * @property {Number String} maxlength 最大输入长度,设置为 -1 的时候不限制最大长度(默认140) * @property {String} confirm-type 设置键盘右下角按钮的文字,仅在type="text"时生效(默认done) * @event {Function} input 输入框内容发生变化时触发 * @event {Function} focus 输入框获得焦点时触发 * @event {Function} blur 输入框失去焦点时触发 * @event {Function} confirm 点击完成按钮时触发 * @event {Function} right-icon-click 通过right-icon生成的图标被点击时触发 * @event {Function} click 输入框被点击或者通过right-icon生成的图标被点击时触发,这样设计是考虑到传递右边的图标,一般都为需要弹出"picker"等操作时的场景,点击倒三角图标,理应发出此事件,见上方说明 * @example <u-field v-model="mobile" label="手机号" required :error-message="errorMessage"></u-field>
