javascript - How to set the word limit on Sina Weibo web version

Question

Just like the title.
To add, maybe you don’t understand what I mean, the number of letters and numbers here and the number of Chinese characters are different

Answer 1

The above is how to write jquery, js can be written like this

document.getElementById('textarea id').value.length;

It has been processed, Chinese is counted as 1 characters, and other characters such as English or numbers are counted as 0.5

Answer 2

Since the upper right corner shows how many words have been entered during onchange, it is obviously the value of js monitoring onchange that takes the length

Just handle it if it exceeds the length

Answer 3

Get the value of the text box, and then determine the length of the value.
