JQuery limits the textarea character limit (number of real-time prompts)

This is a basic function of JQuery. It can limit the number of words in textarea and prompt: You can enter xxx characters. In this example, it is limited to 1000 characters, for details, see the following code:

Copy to ClipboardReference: [www.bkjia.com] $ ('# FashionStatement'). val ('');
Var limitNum = 1000;
Var pattern = 'You can also enter' + limitNum + 'word ';
('{Statementrowchk'{.html (pattern );
$ ('# FashionStatement'). keyup (
Function (){
Var remain = $ (this). val (). length;
If (remain & gt; 1000 ){
Pattern = $ ('the number of words exceeds the limit. Please delete some content ');
}
Else {
Var result = limitNum-remain;
Pattern = 'You can also enter' + result + 'word ';
}
('{Statementrowchk'{.html (pattern );
}
);
