JQuery 表单中textarea字数限制实现代码

$(#FashionStatement).val();
var limitNum = 1000;
var pattern = 还可以输入 + limitNum + 字;
$(#statementRowChk).html(pattern);
$(#FashionStatement).keyup(
function() {
var remain = $(this).val().length;
if (remain > 1000) {
pattern = $(字数超过限制，请适当删除部分内容);
}
else {
var result = limitNum - remain;
pattern = 还可以输入 + result + 字;
}
$(#statementRowChk).html(pattern);
}
);
