Question

I have a form and I am using jQuery validation plugin to validate it. Now I am trying to validate decimal number input.

I have tried the following code, but its not working. Is the problem with the regular expression or the way of writing the custom rule is wrong in my code?

 rules: {
      paid_amount: {
              required:true,
                      rexp: ^[1-9]\d*(\.\d+)?$
      },

   }
     },

 messages: {
             paid_amount: {
                      required: "Enter Paid Amount",
              rexp:"Decimal Numbers Only"
    },  

     }
});

You can use the number validation method found here

From the docs:

$("#myform").validate({
  rules: {
    field: {
      required: true,
      number: true
    }
  }
});

In your case:

rules: {
    paid_amount: {
        required:true,
        number: true
    }
},
messages: {
    paid_amount: {
        required: "Enter Paid Amount",
        number: "Decimal Numbers Only"
    }
}
