Description

Text input method, device, apparatus and storage medium supporting backspace input method

technical field

The present invention relates to the technical field of text input, and in particular, to a text input method, device, device and storage medium supporting a backspace input method.

Background technique

In some software text input boxes, it is sometimes set to allow only certain types of characters to be input, for example, some fields in electronic scale management software are only composed of numbers. For example: item number, shelf life, etc. This is a habit in the industry. In order to prevent fools, the scale management software generally restricts the input of such a text input box to prevent the user from entering characters other than numbers.

In the prior art, the processing method for a text input box that only allows input of numbers is: when a value is input on the keyboard, it is judged whether the current input value is a number or a backspace, and if not, the input value is set to #0 (that is, : Null character), thus realizing the function of allowing only numbers to be entered. However, the prior art has the risk of losing valid information when faced with input methods that generate a delete key.

等。越南常用的输入法工具是unikey，在输入这些带有特殊声调的字母，通过组合键的模式来完成。如输入

是通过按两下a来实现。又如输入字母

是通过按下字母a与w来实现。Taking Vietnamese characters as an example, in addition to the commonly known A to Z, Vietnamese letters also refer to 5 tones to represent. For example, the letter a has multiple tones:

Wait. The commonly used input method tool in Vietnam is unikey. When entering these letters with special tones, the key combination mode is used to complete them. as input

This is done by pressing a twice. like typing letters

This is done by pressing the letters a and w.

其原理是，第一次按下a时，输入法输出a字符的键值(即：在文本框中输入a)；第二次按下a时，输入法先输出退格字符(backspace)的键值(即：将文本框中的a删除)，然后再输出

字符的键值(即：在文本框中输入

)。Although on the surface, unikey is like pinyin, and the corresponding value is typed after combining letters. But in fact, when unikey is entering letters, such as

The principle is that when you press a for the first time, the input method outputs the key value of the character a (ie: enter a in the text box); when you press a for the second time, the input method outputs the backspace character first. Key value (ie: delete a in the text box), and then output

The key value of the character (ie: type in the text box

).

)，这个过程中Unikey输入法会文本输入框输入三个ASCII编码：#97(即：a)、#8(即：退格)和#226(即：

)。其中，#97和#226因为不属于数字和退格，会被置为空值不产生输入动作，而#8会产生退格动作而将之前正常输入的123中的3删除。When the existing scale management tool uses the Unikey input method for input, the wrong value is generated when a letter with a tone is entered by mistake in a field that only allows input of numbers, resulting in the deletion of the normally input number. For example: enter after 123 and press a twice (ie: wrong input

), in this process, the Unikey input method will input three ASCII codes in the text input box: #97 (ie: a), #8 (ie: backspace) and #226 (ie:

). Among them, #97 and #226 will be set to null because they do not belong to numbers and backspace, and will not generate input action, while #8 will generate backspace action and delete 3 in 123 that was normally input before.

In view of this, the applicant hereby proposes the present application after studying the prior art.
