复制代码 代码如下:

<script type=\"text/javascript\">
var checkNo = function(e){
var keyCode = e.charCode ? e.which : e.keyCode;
if(keyCode == 8){
return true;
}
var realkey = String.fromCharCode(keyCode);
var reg = \"\\\\d\";
var regExp = new RegExp(reg);
return regExp.test(realkey);
}
</script>

复制代码 代码如下:

//限制最大输入长度
var checkMaxL = function(length) {
var regC = /[^ -~]+/g;
var regE = /\\D+/g;
var str = jQuery(\"#remark\").val();

if (regC.test(str)){
jQuery(\"#remark\").val(str.substring(0, length));
}

if(regE.test(str)){
jQuery(\"#remark\").val(str.substring(0, length));
}
}
