jquery 验证数值大小

Question

jquery 验证数值大小

Answer 1

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 "));
