JQuery Validation <select> min depends on other field, not working

Question

I have a select \"ArrearsLHOLocation\" that has an option \"None Selected\" with a value of -1 and all other selectable values are greater than 0.

Here is the rule d

Answer 1

A select can only be required or not. I've never seen the min rule used on a select to force the user to choose an option.

Your "None Selected" option should contain value="" and then when you declare the required rule on this, the user will be forced to select any option other than "None Selected".

    None Selected
    option 1
    option 2
    option 3

Then your depends parameter would simply need to return a boolean to state whether the user needs to select an option.

$('[name="list"]').rules("add", {
    required: {
        depends: function (elem) {
            return $("#check").is(":checked");
        }
    },
    messages: {
        required: "Select from the list"
    }
});

EDIT:

Since you want to keep your first option as value="-1", you'll need to create a custom rule/method using the addMethod() method that recognizes your first option as invalid.

$.validator.addMethod('select', function(value, element) {
    return (value == -1) ? false : true;
});
