jQuery.validator.format() - Where does it get it's parameter values from?
in Using jQuery Plugins
•
7 years ago
Reading through the jQuery.validator documentation on the format() function
, there is an example shown like this:
jQuery.validator.format("{0} is not a valid value");
There are no additional parameters given to the function, so I guess the "{0}" will not be getting replaced?
Or if so, where does it get its value from?
Thanks for enlightening me.

I'm in the documentation reading phase. Don't want to try/error
myself - want to know from the documentation or external knowledge. So I
didn't try. I'm not the gambling type of programmer.

The docs don’t say much about it.
jQuery.validator.format is an internal function that you could use
as well.

Yepp. That's why I have started this thread.
I don't understand. Actually this current thread is about jQuery.validator.format(). Are you sure you wanted to reply to this thread with your answer?jQuery.validator.format is an internal function that you could use as well.

Yes. Often when writing plugins, some of the internal functions are of
general use. They are made available on the outside for your use.
Most users won’t use jQuery.validator.format.
But if you do, you would use it like…

Ah, OK, I can see my mistake now:
validator.format() doesn't return a string, it yields a function object which you then call with appropriate parameters.
Function name and function description in the documentation are misleading. The return value type is not even mentioned.
You've got to look sharp in the example to see that validator.format() does not "replace {n} placeholders with arguments" but instead creates a function that can be called to replace {n} placeholders with arguments.
Thanks for taking the time!

By default, the value of {0},{1}.. in validator.format() get from parameter that u pass in. Example you define a method name CheckABC:
$.validator.addMethod("CheckABC", function (value, element, para) {return false},jQuery.validator.format("Value: {0}"))
and using that method as:
$.validator.addClassRules({
ClassToCheck: {
CheckABC: "hahaha"
}
});
then, any input with class name = ClassToCheck, the error will show: Value hahaha.
Note: The para can be a array.
Another thing worth to note is, you also can pass a function instead of message like this:
$.validator.addMethod("CheckABC", function (value, element, para) {return false}, function(para, element){
var newPara = "New " + para; // manipulate your value
return Jquery.validator.format("Value: {0}", newPara);
})
and error message would be Value: new hahaha
