Standard Attribute Validators The validation rules for standard HTML5 attributes are handled entirely by the browser using the. As such, this plugin isn't in control of things like what qualifies as a valid email address or URL.
Validation protocols may be customized to meet each laboratory's unique certification requirements. TRINITY V3 strictly complies with 21 CFR Part 11 electronic signature requirements from reading test plates to reporting test results.

If you find you need more restrictive validations for these fields, you can use the pattern attribute to further constrain what's acceptable. Be careful that you aren't too restrictive though, which might lead to false negatives and a poor user experience. For example, you'd be surprised at what kinds of are considered valid according to standards.
Cross-browser Compatibility Because this plugin depends on the HTML5 Constraint Validation API, Internet Explorer 9 and older are not supported. If you need to support these browsers, you must add a polyfill like Ryan Seddon's. To display error messages, include a container after the input field with both help-block and with-errors classes.

Alternatively, you can add data-validate='true' / data-validate='false' to a specific input to force its inclusion / exclusion in the set of validated fields. Options Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-delay='. Error messages for individual form fields Error messages for individual form fields can alternatively be specified through the use of data attributes.
You can specify an error message for each type of validator on a field, i.e. Data-pattern-error=', data-required-error=', data-match-error=', etc. Or use data-error=' for a blanket error message to show for any errors on that field. Methods.validator(options) Attaches a validator to a form collection.validator('update') Updates the collection of inputs that will be validated. Call this method if the set of fields which need to be validated has changed.validator('validate') Immediately validates the entire form.validator('destroy') Destroys form validator and cleans up data left behind.

Was created by the W3C to help Web developers validate CSS. Validation Warnings The W3C CSS Validator checks for CSS1, CSS2, CSS3, and CSS4 properties. Some browsers use vendor extensions to simulate CSS3 and CSS4 properties. Vendor extensions can create warnings in the W3 CSS validation prosess. Vendor Extensions W3.CSS uses vendor extensions to support older browsers. Browser vendors are working to stop using prefixes in future browser versions. Until then, some extensions will have to be used to make modern CSS work in all browsers.
Below is a list of the most common vendor extensions used: Extension Browser -webkit- Chrome, Safari, Opera -moz- Firefox -o- Old Opera versions -ms- Microsoft Edge and Internet Explorer.
