Methods

ajax

Send the data to the server for testing.

Synopsis

glow.forms.tests.ajax();

Description

A request to the given URL will be made and the response will be passed to the given callback.

'arg' is the function to handle the response from the server.

'url' is the url to call. You can use placeholders in here for form values (see example).

Example

function handleResponseText(response) {
  if (response.text() == "OK") {
    return glow.forms.PASS;
  } else {
    return glow.forms.FAIL;
  }
}

myForm.addTests(
  "username",
  ["ajax", {
    arg: handleResponseText,
    url: "/cgi/checkname.cgi?name={username}"
  }]
);

count

There must be exactly the given number of values submitted with this name.

Synopsis

glow.forms.tests.count();

Description

This is useful for multiple selects and checkboxes that have the same name.

Example

myForm.addTests(
  "fieldName",
  ["count", {
    arg: "2"
  }]
);

custom

Create a custom test.

Synopsis

glow.forms.tests.custom();

Description

'arg' is a function which tests the form value.

The function is given the following parameters:

values

An array of values submitted for that form field. If you are only expecting one value, it can be accessed via values[0]

opts

An object of any additional data included with the test

callback

This is a function used to tell Glow whether the test has passed or not. A callback is used rather than 'return' to allow async tests. The first parameter is either glow.forms.PASS or glow.forms.FAIL, the second is the success or failure message.

formData

This is an object of all values captured in the form.

Example

myForm.addTests(
  "username",
  ["custom", {
    arg: function(values, opts, callback, formData) {
      for (var i = 0, len = values.length; i < len; i++) {
        if (values[i] == "Jake") {
          callback(glow.forms.FAIL, "The name Jake is not allowed.");
          return;
        }
      }
      callback(glow.forms.PASS, "Good name.");
    }
  }]
