我写了一段正则,想在js中匹配,可是使用test、exec后,都不好使,下面是代码,大家帮忙看下


<script> <br /> <br /> function aa(){ <br /> var pattern="/^[1-9]/d*$/"; <br /> var a = "222"; <br /> if(pattern.test(a)){ <br /> alert("成功"); <br /> }else{ <br /> alert("失败"); <br /> } <br /> } <br /> window.onload = aa(); <br /> <br /> </script>

打开页面后,不弹出文本框,啥也没有,怎么回事?


回复讨论(解决方案)

正则写错了
不是 var pattern="/^[1-9]/d*$/";
应该是 var pattern="/^[1-9]\d*$/";

果然,谢谢
