jquery 验证数值大小

Posted 2023-03-13

有TextBox tbA、tbB两个 在都有值的情况下用jQuery.validate()验证 tbA数值小于tbB数值 都是数值，比大小 用jQuery.validate.js 怎么比大小呢

参考技术A 简单实现代码如下：
$("#rewardForm").validate(
rules:

"reward":

required:
true,
digits:true,
balance:true,
checkBalance:true

,
messages:
"reward":
digits:"
*
请填写正确的转账金额（应为数字）",
required:"
*
请输入转账金额
"


);
jQuery.validator.addMethod("balance",
function(value,element)

var
sumreward=$("#sumreward").val();
return
this.optional(element)
||
value<=
sumreward;
,
$.validator.format("
*
余额不足
"));
jQuery.validator.addMethod("checkBalance",
function(value,element)

var
balance=0;
return
this.optional(element)
||
value>balance;
,
$.validator.format("
*
转账金额必须大于0
"));
