Run Code Online (Sandbox Code Playgroud) 我有以下代码,它运行良好,但问题是,超过500个字符后,它开始允许用户键入(它接受字符而不是限制它们!).

$('#txtAboutMe').keyup(function () {
var text = $(this).val();
var textLength = text.length;`enter code here`
if (text.length > maxLength) {
$(this).val(text.substring(0, (maxLength)));
alert("Sorry, you only " + maxLength + " characters are allowed");
}
else {
//alert("Required Min. 500 characters");
}
});"
