求一个正则表达式“非0整数或两位小数”

[小小骨头]

两位小数也不能输入0.0或0.00

^([1-9][0-9]*)+(.[0-9]{1,2})?$

^([1-9][0-9]*)+(.[0-9]{1,2})?$

负小数也可以输入

[天际的海浪]

^-?(?!0+(\.0*)?$)\d+(\.\d{1,2})?$

^-?(?!0+(\.0*)?$)\d+(\.\d{1,2})?$

试了一下，这样的话，任何数字都不能输入了

试了一下，这样的话，任何数字都不能输入了[/quote] 没问题啊

    var reg = /^-?(?!0+(\.0*)?$)\d+(\.\d{1,2})?$/;
    [".1","0.1","1.12","123.12","92","092",".13","-1","-1.2","0","0.0","0.00","00","1.234","5.10"].forEach(function(v){

EE_D692.tmp.htm:18 true "0.1" EE_D692.tmp.htm:18 true "-1.2" ==============这就应该有问题吧，他要求是有小数必须要两位。“非0整数或两位小数”
