The following is a sample code for determining the input string length in JavaScript code (Chinese characters are counted as two characters, and letters and numbers are counted as one ). I think this is quite good. now I will share it with you and give you a reference. Let's take a look at the following small series to bring you an example code for JS to judge the length of the input string (Chinese characters are counted as two characters, and letters and numbers are counted as one ). I think this is quite good. now I will share it with you and give you a reference. Let's take a look at it with Xiaobian.
Example code for js to determine the length of the input string (Chinese characters are counted as two characters, and letters and numbers are counted as one)
In text input, the submission fails due to the length limit of the database table field, so this method is used for verification.
Not much nonsense about the code:
Js determines the length of the input string (Chinese characters count as two characters, and letters and numbers count as one)
