javascript pattern只允许数目字，英文字母和一些特殊字符

<script type="text/javascript">
    var emailPattern = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/;
    var chPattern = /^[A-Za-z0-9  \!\@\#\$\^\&\*\-\_\+\=\:\\\'\;\,\.\/\?\(\)\{\}\[\]\<\>]*$/;
   
    var s = "yang Hua Jie qwe231@[]";
    alert(chPattern.test(s) );
</script>
