限制前台输入太多字数：
js中：function htmlstr(str,len){
var htmlContent = str;
var regEx = /<[^>]*>/g;
var nakeText = htmlContent.replace(regEx, "");
if(nakeText.length >=len){
document.write(nakeText.substring(0,len)+"...");
}else{
document.write(nakeText);
}
}
html中：
<script type="text/javascript">
htmlstr('${remark}', 180)
</script>
后台中在添加方法就限制：
userSkill.setRemark(CommonUtils.replace(userSkill.getRemark()));
