JS常用正则表达式及验证时间的正则表达式

<input type="text" maxlength="8" class="form-control" id="amount" style="margin-right: 2px;" value="" onChange="count();" onkeyup="if (this.value==this.value2) return; if (this.value.search(/^/d*(?:/./d{0,2})?$/)==-1) this.value=(this.value2)?this.value2:'';else this.value2=this.value;">元//第二种对于表单动态增加的方式，只能在js方法中验证。var amount=$("#amount").val();if (amount.search(/^/d*(?:/./d{0,2})?$/)==-1) {alert("金额格式不对，最多有两位小数");return false;}

var reg=//w+([-+.]/w+)*@/w+([-.]/w+)*/./w+([-.]/w+)*/;var email=$("#email").val();if(!reg.test(email) ){alert("请输入符合规范的邮箱账号！");return false;}

function isCharNum(flagValue){var flagPattern=/^[a-zA-Z0-9]*$/; //是否为字母和数字result=flagPattern.test(flagValue);return result;}
