jQuery验证自定义方法规则和带有动态名称的消息？

Question

I have a validation rule that I want to add using a variable varFunctionID, which represents a custom validation method. Rather than looking for the value of the variable, it searches for a function called varFunctionID, which does not exist. How can I ensure that the value, not the name, of the variable is used? Also, I cannot use the name in place of the variable.

var varFunctionID = "nameOfMyCustomValidationFunction";

$('#myField').rules('add', {
    varFunctionID: true
    },
    messages: {
        varFunctionID: "My message."
    }
});

* EDIT * There is no way to make the name dynamic. The way to handle such a need is to pass in a parameter to the validation method, like so:

$('#myField').rules('add', {
    myFunction: { myParm: "parm" }
    },
    messages: {
        myFunction: "My message."
    }
});

jQuery.validator.addMethod("myFunction", function (value, element, options) {
            var passParm= options.myParm;
});

Not sure why you would need to do such a thing. As your OP is written, it's entirely unclear why you can't use the actual name of the custom method in the first place.

You cannot do what you're asking . You would need to use the actual name of your custom method within the .rules() method.

EDIT : My previously suggested workaround is not viable.

The custom method is not meant to have a "dynamic" name and I'm not sure why the name would ever need to be dynamic. The custom method is created and you either assign it to one or more fields or don't. Anything "dynamic" about this function would be taken care of by passing in custom parameters.

See .addMethod() method documentation .
