Procedural API Description
|
|
|
|
The main aim is to make input validation expressible in a simple format.
|
|
You define profiles which declare the required and optional fields and any constraints they might have.
|
|
The results are provided as an object that makes it easy to handle missing and invalid input.
|
|
|
|
Usage
|
|
|
|
var results = dojo.validate.check(form, profile);
|
|
|
|
Profile Object
|
|
|
|
var profile = {
|
|
// filters change the field value and are applied before validation.
|
|
trim: ["tx1", "tx2"],
|
|
uppercase: ["tx9"],
|
|
lowercase: ["tx5", "tx6", "tx7"],
|
|
ucfirst: ["tx10"],
|
|
digit: ["tx11"],
|
|
|
|
// required input fields that are blank will be reported missing.
|
|
// required radio button groups and drop-down lists with no selection will be reported missing.
|
|
// checkbox groups and selectboxes can be required to have more than one value selected.
|
|
// List required fields by name and use this notation to require more than one value: {checkboxgroup: 2}, {selectboxname: 3}.
|
|
required: ["tx7", "tx8", "pw1", "ta1", "rb1", "rb2", "cb3", "s1", {"doubledip":2}, {"tripledip":3}],
|
|
|
|
// dependant/conditional fields are required if the target field is present and not blank.
|
|
// At present only textbox, password, and textarea fields are supported.
|
|
dependencies: {
|
|
cc_exp: "cc_no",
|
|
cc_type: "cc_no",
|
|
},
|
|
|
|
// Fields can be validated using any boolean valued function.
|
|
// Use arrays to specify parameters in addition to the field value.
|
|
constraints: {
|
|
field_name1: myValidationFunction,
|
|
field_name2: dojo.validate.isInteger,
|
|
field_name3: [myValidationFunction, additional parameters],
|
|
field_name4: [dojo.validate.isValidDate, "YYYY.MM.DD"],
|
|
field_name5: [dojo.validate.isEmailAddress, false, true],
|
|
},
|
|
|
|
// Confirm is a sort of conditional validation.
|
|
// It associates each field in its property list with another field whose value should be equal.
|
|
// If the values are not equal, the field in the property list is reported as Invalid. Unless the target field is blank.
|
|
confirm: {
|
|
email_confirm: "email",
|
|
pw2: "pw1",
|
|
}
|
|
};
|
|
|
|
Results Object
|
|
|
|
isSuccessful(): Returns true if there were no invalid or missing fields, else it returns false.
|
|
hasMissing(): Returns true if the results contain any missing fields.
|
|
getMissing(): Returns a list of required fields that have values missing.
|
|
isMissing(field): Returns true if the field is required and the value is missing.
|
|
hasInvalid(): Returns true if the results contain fields with invalid data.
|
|
getInvalid(): Returns a list of fields that have invalid values.
|
|
isInvalid(field): Returns true if the field has an invalid value.
