-  * 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 https://uviewui.com/components/input.html
 
-  * @property {String | Number}  value          输入的值
 
-  * @property {String}      type          输入框类型,见上方说明 ( 默认 'text' )
 
-  * @property {Boolean}      fixed          如果 textarea 是在一个 position:fixed 的区域,需要显示指定属性 fixed 为 true,兼容性:微信小程序、百度小程序、字节跳动小程序、QQ小程序 ( 默认 false )
 
-  * @property {Boolean}      disabled        是否禁用输入框 ( 默认 false )
 
-  * @property {String}      disabledColor      禁用状态时的背景色( 默认 '#f5f7fa' )
 
-  * @property {Boolean}      clearable        是否显示清除控件 ( 默认 false )
 
-  * @property {Boolean}      password        是否密码类型 ( 默认 false )
 
-  * @property {String | Number}  maxlength        最大输入长度,设置为 -1 的时候不限制最大长度 ( 默认 -1 )
 
-  * @property {String}      placeholder        输入框为空时的占位符
 
-  * @property {String}      placeholderClass    指定placeholder的样式类,注意页面或组件的style中写了scoped时,需要在类名前写/deep/ ( 默认 'input-placeholder' )
 
-  * @property {String | Object}  placeholderStyle    指定placeholder的样式,字符串/对象形式,如"color: red;"
 
-  * @property {Boolean}      showWordLimit      是否显示输入字数统计,只在 type ="text"或type ="textarea"时有效 ( 默认 false )
 
-  * @property {String}      confirmType        设置右下角按钮的文字,兼容性详见uni-app文档 ( 默认 'done' )
 
-  * @property {Boolean}      confirmHold        点击键盘右下角按钮时是否保持键盘不收起,H5无效 ( 默认 false )
 
-  * @property {Boolean}      holdKeyboard      focus时,点击页面的时候不收起键盘,微信小程序有效 ( 默认 false )
 
-  * @property {Boolean}      focus          自动获取焦点,在 H5 平台能否聚焦以及软键盘是否跟随弹出,取决于当前浏览器本身的实现。nvue 页面不支持,需使用组件的 focus()、blur() 方法控制焦点 ( 默认 false )
 
-  * @property {Boolean}      autoBlur        键盘收起时,是否自动失去焦点,目前仅App3.0.0+有效 ( 默认 false )
 
-  * @property {Boolean}      disableDefaultPadding  是否去掉 iOS 下的默认内边距,仅微信小程序,且type=textarea时有效 ( 默认 false )
 
-  * @property {String | Number}  cursor          指定focus时光标的位置( 默认 -1 )
 
-  * @property {String | Number}  cursorSpacing      输入框聚焦时底部与键盘的距离 ( 默认 30 )
 
-  * @property {String | Number}  selectionStart      光标起始位置,自动聚集时有效,需与selection-end搭配使用 ( 默认 -1 )
 
-  * @property {String | Number}  selectionEnd      光标结束位置,自动聚集时有效,需与selection-start搭配使用 ( 默认 -1 )
 
-  * @property {Boolean}      adjustPosition      键盘弹起时,是否自动上推页面 ( 默认 true )
 
-  * @property {String}      inputAlign        输入框内容对齐方式( 默认 'left' )
 
-  * @property {String | Number}  fontSize        输入框字体的大小 ( 默认 '15px' )
 
-  * @property {String}      color          输入框字体颜色  ( 默认 '#303133' )
 
-  * @property {Function}      formatter          内容式化函数
 
-  * @property {String}      prefixIcon        输入框前置图标
 
-  * @property {String | Object}  prefixIconStyle      前置图标样式,对象或字符串
 
-  * @property {String}      suffixIcon        输入框后置图标
 
-  * @property {String | Object}  suffixIconStyle      后置图标样式,对象或字符串
 
-  * @property {String}      border          边框类型,surround-四周边框,bottom-底部边框,none-无边框 ( 默认 'surround' )
 
-  * @property {Boolean}      readonly        是否只读,与disabled不同之处在于disabled会置灰组件,而readonly则不会 ( 默认 false )
 
-  * @property {String}      shape          输入框形状,circle-圆形,square-方形 ( 默认 'square' )
 
-  * @property {Object}      customStyle        定义需要用到的外部样式
 
-  *
 
-  * @example <u-input v-model="value" :password="true" suffix-icon="lock-fill" />
