                 * 1. 输入框输入

                 *  - 输入不可解析为合法数字，进行格式化后显示在input框
                 * 2. 键盘点击上下按钮（input value根据受控值进行更改）
                 * 3. keepFocus+鼠标点击上下按钮（input value根据受控值进行更改）
                 *
                 * The focusing state is the input state, and the controlled value of the input state needs special treatment
                 * For example:
                 *  - input legal value
                 *      123 = > input value should also be 123, and the number should be set to 123
                 *  - input illegal value, only set the input value, do not set the illegal number
                 *      abc = > input value This is abc at this time, but it will be formatted after being out of focus
                 *      100 (out of range) = > input value should be 100, but no number
                 *
                 * There are three ways to maintain the input state
                 * 1. input box input
                 *  - input can be resolved into legal numbers, input value is determined according to the input value, and input value is updated when out of focus
                 *  - input cannot be resolved into legal numbers, and it will be displayed in the input box after formatting
                 * 2. Keyboard click on the up and down button (input value is changed according to the controlled value)
                 * 3.keepFocus + mouse click on the up and down button (input value is changed according to the controlled value)
