jQuery Forum

First of all, for Jörn, thanks for all the work you put into this plugin; no validation plugin will ever suit everyone's needs but this one comes damn close; excellent work.

Now for the questions.

1. Is it possible to have a custom rule set with custom error messages? preferably one that's called by an attribute value? or what would be the best way to implement that?

For example (something like):

1. // Script
2. jQuery.validator.addRuleSets({
3.     rules: {
4.         customRule: {
5.                 required: function() {
6.                     if(jQuery('#someField').val() && jQuery('#someOtherField').val()){return false}
7.                     else return true;
8.                 },
9.                 rangelength: [2,5],
10.                 digits: true,
11.                 remote: {
12.                     url: "/url/validateSomething",
13.                     type: "post",                  
14.                     data: {
15.                         extraData: function() {
16.                             return jQuery('#element').val();
17.                         }
18.                     }
19.                 }
20.         },
21.         customRule2: {
22.                 required:true,
23.                 digits: true
24.         }
25.     },
26.     messages: {
27.         customRule: {
28.             required: "Some Error Text",
29.             rangelength: "Some Other Error Text",
30.             digits: "etc",
31.             remote: "etc"
32.         },
33.         customRule2: {
34.             required: "Some Error Text",
35.             digits: "etc",
36.         }
37.     }
38. });
39. 
    
40. // HTML
41. <input id="somefield" name="somefield" type="text" validate="do:customRule" />
42. <input id="someotherfield" name="someotherfield" type="text" validate="do:customRule2" />

The reason for this is a little complicated but basically it's because I can't count on concrete field names / ids  (or I would simply write the rules based on those). Additionally, I would rather not jam 30 lines of script into an attribute value (or class); plus, I am a firm believer in not over-abusing class names for the sake of script processing even if it doesn't validate (which is why I want to look for an alternative to addClassRules - though it isn't clear whether that supports custom error messages without custom methods either).

2. Is it possible to reference the element being validated in a remote call without doing it absolutely?

For example (something like):

1. // DO:
2. remote: {
3.     url: "/url/validateSomething",
4.     type: "post",                  
5.     data: {
6.         someKey: function() {
7.             return jQuery(this).val();
8.         },
9.     }
10. }
11. // BUT NOT:
12. remote: {
13.     url: "/url/validateSomething",
14.     type: "post",                  
15.         data: {
16.             someKey: function() {
17.                 return jQuery('#absoluteReference').val();
18.             }
19.         }
20.     }
21. }

Again, for the same reason. I can't count on field names / ids and would like to send the server a specific named key/value pair regardless of the actual field name key. (this assumes, of course, that I find a solution to question 1)

3. Is it possible to return a custom error message when using the "remote" rule?

For example (something like):

1. remote: {
2.     url: "/url/validateSomething",
3.     type: "post",                  
4.     data: {
5.         extraData: function() {
6.             return jQuery('#element').val();
7.         },
8.     message: {returnedJSONObject.error}
9.     }
10. }

Thanks in advance,

James.
