|
|
*
|
|
* The LuCI validation class provides functions to perform validation
|
|
* on user input within various [form]{@link LuCI.form} input fields.
|
|
*
|
|
* To import the class, use `'require validation'`. To import it in
|
|
* external JavaScript, use `L.require("validation").then(...)`.
|
|
*
|
|
* Note: it is not required to import this class in forms for use: it is
|
|
* imported by {@link LuCI.ui ui} where {@link LuCI.form form} elements
|
|
* are defined.
|
|
*
|
|
* A typical validation is instantiated by first constructing a
|
|
* {@link LuCI.form} element and
|
|
* by adding a [datatype]{@link LuCI.form.AbstractValue#datatype} to the
|
|
* element properties.
|
|
*
|
|
* @example
|
|
*
|
|
* 'use strict';
|
|
* ...
|
|
*
|
|
* let m, s, o;
|
|
*
|
|
* ...
|
|
*
|
|
* o = s.option(form.Value, 'some_value', 'A value element');
|
|
* o.datatype = 'ipaddr';
|
|
*
|
|
* ...
|
|
*
|
|
* @example <caption>A validator stub can be instantiated so:</caption>
|
|
*
|
|
* const stubValidator = {
|
|
* factory: validation,
|
|
* apply: function(type, value, args) {
|
|
* if (value != null)
|
|
* this.value = value;
|
|
*
|
|
* return validation.types[type].apply(this, args);
|
|
* },
|
|
* assert: function(condition) {
|
|
* return !!condition;
|
|
* }
|
|
* };
|
|
*
|
|
* @example <caption>and later used so in a custom `o.validate` function:</caption>
|
|
*
|
|
* ...
|
|
* stubValidator.apply('ipaddr', m4 ? m4[1] : m6[1])
|
|
* ...
|
|
*
|
|
* @example <caption> One can also add validators to HTML UI elements via
|
|
* {@link LuCI.ui#addValidator}: </caption>
|
|
*
|
|
* ...
|
|
* s.renderSectionAdd = function(extra_class) {
|
|
* var el = form.GridSection.prototype.renderSectionAdd.apply(this, arguments),
|
|
* nameEl = el.querySelector('.cbi-section-create-name');
|
|
* ui.addValidator(nameEl, 'uciname', true, function(v) {
|
|
* let sections = [
|
|
* ...uci.sections('config', 'section_type1'),
|
|
* ...uci.sections('config', 'section_type2'),
|
|
* ];
|
|
* if (sections.find(function(s) {
|
|
* return s['.name'] == v;
|
|
* })) {
|
|
* return _('This may not share the same name as other section type1 or section type2.');
|
|
* }
|
|
* if (v.length > 15) return _('Name length shall not exceed 15 characters');
|
|
* return true;

* }, 'blur', 'keyup');
