如何判断这样一个字符串？

[yanboneck]

如何判断这个字段是否是“wjXX-消XXXX”这种格式的？XX代表阿拉伯数字？

呵呵，这是判断武警消防部队车牌号的。

你应该判断从第一位到第二位为:WJ 然后第6，7位为:-消

取出后4位和后6、7位进行判断

function wolf(x)
{
return(new RegExp(/^wj\d{2}\-消\d{4}$/ig).test(x));
}
//测试：
alert(wolf("wjXX-消XXXX"));
alert(wolf("wj11-消1233"));
alert(wolf("wj1-消1"));
alert(wolf("wj00-狼1233"));
alert(wolf("京wj00-消1233B"));
