Additional InputValidators:

Tutorial/Demo

Here are the validators that are included in this libary. Add the name to any input's data-validators property and then create a new Form.Validator and these will automatically be applied.

Validator: validate-nospace

Enforces that there are no spaces in the input value.

Validator: validate-enforce-oncheck

When added to a checkbox/radio button, and a list (array) of element id's can be passed in (toEnforce) to enforce validation on those fields.

Example

<input type="checkbox" class="validate-enforce-oncheck toEnforce:['name','email','phone']"/>
//when checked, the inputs with the ids 'name', 'email', and 'phone' will also be validated on change/submit
 
<input type="checkbox" class="validate-enforce-oncheck enforceChildrenOf:'someParent'"/>
//when checked, all inputs inside $('someParent') will be validated on change/submit

Validator: validate-ignore-oncheck

When added to a checkbox/radio button, and a list (array) of element id's can be passed in (toIgnore) in the validatorProps to ignore validation on those fields.

Example

<input type="checkbox" class="validate-ignore-oncheck toIgnore:['name','email','phone']"/>
//when checked, the inputs with the ids 'name', 'email', and 'phone' will NOT be validated on change/submit
 
<input type="checkbox" class="validate-ignore-oncheck ignoreChildrenOf:'someParent'"/>
//when checked, all inputs inside $('someParent') will NOT be validated on change/submit

Validator: validate-toggle-oncheck

When the input is checked or un-checked, the inputs defined will be toggled from ignore (if the input is un-checked) to enforce (if it is checked).

Example

<input type="checkbox" class="validate-toggle-oncheck toToggle:['name','email','phone']"/>
//when checked, the inputs with the ids 'name', 'email', and 'phone' will be validated on change/submit
//when unchecked, they will be ignored
 
<input type="checkbox" class="validate-toggle-oncheck toToggleChildrenOf:'someParent'"/>
//when checked, all inputs inside $('someParent') will be validated on change/submit
//when unchecked, they will be ignored

Validator: validate-required-check

Forces the user to check a checkbox (thing agreeing to terms and conditions).

Validator: validate-reqchk-bynode

At least one checkbox/radio is required to be checked in this node. nodeId needs to be passed to the validatorProps.

Example

<input type="checkbox" class="validate-reqchk-bynode nodeId:'someParent'"/>
 
//you can also specify a selector for the parent
<input type="checkbox" class="validate-reqchk-bynode nodeId:'someParent' selector:'input.foo[type=checkbox]'"/>

Validator: validate-reqchk-byname

At least one checkbox/radio is required to be checked in this name group. You can specify an optional label that completes the error message: "Please select a label." - it defaults to either "checkbox" or "radio" - the type of the input. By default it uses the name of the input to find all inputs with the same name but you can specify the optional validatorProps name groupName if you prefer.

Example

<input type="checkbox" class="validate-reqchk-byname label: 'flavor'" name="favoriteFlavor"/>

Validator: validate-after-date

Takes in the id of a start field id and compares it to make sure the given value is later than or equal to the start date. If no other input is specified it uses the current time. The other validatorProps option is afterLabel which completes the sentence "The date should be the same or after label." If you do not specify an afterLabel, either "the current time" or "the start date" is used (the latter is used if afterElement is specified);

Example

<input type="text" name="endDate" class="validate-after-date afterElement:'startDate'"/>
//if you don't include afterElement the current time is used

Validator: validate-before-date

Takes in the id of a end field id and compares it to make sure the given value is before or equal to the end date. If no other input is specified it uses the current time. The other validatorProps option is beforeLabel which completes the sentence "The date should be the same or before label." If you do not specify an beforeLabel, either "the current time" or "the end date" is used (the latter is used if beforeElement is specified);

Example

<input type="text" name="startDate" class="validate-before-date beforeElement:'endDate'"/>
//if you don't include beforeElement the current time is used

Validator: validate-custom-required

Required field with an option to define what an empty value is. For example, if you have a list months in a drop down list and first option is "select month" has a value of 'null', you can define a custom-required with emptyValue='null', so it's treated as an empty value.

Example

<select class="validate-custom-required emptyValue:'null'">
    <option value="null">Select One</option>
    ...etc.
</select>

Validator: validate-same-month

Takes another input's id and makes sure both ranges are within the same month. Pass in the sameMonthAs value in the validatorProps as the id of the form to compare to.

Example

<input class="validate-same-month sameMonthAs:'startDate'"/>

Validator: validate-match

Takes in an id of a field and matches them together. Can also take matchName that is used in the error message (i.e.: password confirmations). matchName defaults to the name of the other field, which isn't always very helpful, so you should specify it.

<input type="input" class="validate-match matchInput:'password' matchName:'password'"/>
//error msg: This field needs to match the password field.

Validator: validate-cc-num

Validates that an input is a valid credit card number (Visa, MasterCard, Amex, Discover). Note that it replaces all non-numeric characters to the value (but not to the input's displayed value) before it applies validation, so the user could put in dashes, letters, punctuation, whatever, but if the numbers in the value without those things makes a valid CC number, it will pass.

<input type="input" class="validate-cc-num"/>
