Here is how i would implement the validation rule :
这是我将如何实现验证规则:
$('.myinput').val().match(/^[+-]?$\d(?:\.\d\d)?$/)
The problem with your pattern is that it is not fixed-length, so hard to code in mask, and you may encounter some people giving $3.5, which is not what you want. With such a pattern of yours, I think it will be hard not to fall back on regexp matching.
你的模式的问题是它不是固定长度的,所以在掩码中很难编码,你可能会遇到一些人给3.5美元,这不是你想要的。有了你的这种模式,我认为很难不依赖正则表达式匹配。
You may consider making the cent part mandatory, in which case your pattern is almost ok, just add .99 at the end and it should do it (although as a user I would hate to have to start my currency with a space character...).
您可以考虑强制使用美分部分,在这种情况下,您的模式几乎没问题,只需在最后添加 0.99 就可以了(尽管作为用户,我不希望以空格字符开头我的货币.. .)

Just to clarify Antony response, the plugin that he's using is jquery-maskmoney:
为了澄清安东尼的回应,他使用的插件是 jquery-maskmoney:

I think this will help you.
我认为这会对你有所帮助。
Use the syntax
使用语法
$(mask_id).maskMoney({showSymbol:false,decimal:'.',precision:2});
You can show the symbol but it is probably better to hide it.
您可以显示符号,但最好隐藏它。

I know that in mask you can also make some of the mask optional, so you might be able to get away with this
我知道在面具中你也可以选择一些面具,所以你可以摆脱这个
$.mask.definitions['~']='[ +-]';
$(".currency").mask("~?.99");
