jQuery验证规则内置

Question

I want to use min: 1 but I only want the rule to apply under some condition--which I think I can give in a depends function.

I want something like

rules: {
    field: {
        min: 1,
        depends: function(element) {
            return element.disabled == false;
        }
    }
}

See here for something similar https://stackoverflow.com/a/1090847/1333713

My rules above will still apply the min rule. How can I get it to respect my depends ?

Answer 1

To pass parameters to rules that require them, set a property named param . Like this,

rules: {
    myInputField: {
        min: {
            depends: function(element) {
                return element.disabled == false;
            },
            param: 1
        }
    }
}

Summary: when the validator validates myInputField , it will run the depends function to see if it should apply the min rule. If the depends function evaluates to true, the validator applies the min rule with the parameter 1 . This is the way to conditionally apply rules that take parameters.
