/**
* Field 输入框
* @description 此组件可以实现表单的输入与校验包括 "text" "textarea" 类型
* @tutorial https://ext.dcloud.net.cn/plugin?id=21001
* @property {String } type 输入框的类型默认text
* @property {Boolean} required 是否必填左边您显示红色"*"默认false
* @property {String } leftIcon label左边的图标限uni-ui的图标名称
* @property {String } iconColor 左边通过icon配置的图标的颜色默认#606266
* @property {Boolean} rightIcon 输入框右边的图标名称限uni-ui的图标名称默认false
* @property {String } label 输入框左边的文字提示
* @property {Number } labelWidth label的宽度单位px默认65
* @property {String } labelAlign label的文字对齐方式默认left
* @property {String } labelPosition label的文字的位置默认left
* @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 {String } placeholder 输入框的提示文字
* @property {String } placeholderStyle placeholder的样式(内联样式字符串)"color: #ddd"
* @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} focus 是否自动获得焦点默认false
* @property {Boolean} disabled 是否不可输入默认false
* @property {Number } 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 } confirmType 设置键盘右下角按钮的文字仅在type="text"时生效默认done
* @property {String } errorMessage 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 {Number } clearSize 清除图标的大小单位px默认15
* @property {Boolean} trim 是否自动去除两端的空格
* @property {String } name 表单域的属性名在使用校验规则时必填
* @property {Array } rules 单行表单验证规则接受一个数组
* @property {Boolean} inputBorder 是否显示input输入框的边框默认false
* @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 {Boolean} auto-height 是否自动增高输入区域type为textarea时有效默认true
* @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 <uni-field v-model="mobile" label="手机号" required :error-message="errorMessage"></uni-field>
