问题 I am using angular-ui-select within a website where the styled select fields are configured with an own tag named ui-select . This works great, but doing a W3C validation leads to this error: Element ui-select not allowed as child of element div in this context. (Suppressing further errors from this subtree.) Here's an example code: <!doctype html> <html lang="en"> <head><title>x</title></head> <body> <div> <ui-select></ui-select> </div> </body></html> I understand that <ui-select> is not

Hosting W3 XML Schema files locally

阅读更多关于 Hosting W3 XML Schema files locally

I work at a company where we have our own XML language with its own set of schemas that validate against the W3 schema . For business reasons, I need to host these files internally instead of relying on the web hosted versions. I have little experience with XML schemas and am wondering what exactly this means. Is it as simple as copying and pasting the page source into my own file and pointing our other schemas there? Do I need to worry about the namespace documents as well? Any help here is appreciated. Thanks. kjhughes To host external XSDs, including any from W3C, locally: Identify external

w3c markup validator ampersand (&) error

阅读更多关于 w3c markup validator ampersand (&) error

Is there any workaround for the w3c validation error for an & present in urls or some other place in HTML markup? It says: & did not start a character reference. (& probably should have been escaped as & .) The ampersand in my case is a part of a url for gravatar thumbnail. This is the problematic part of a url: c91588793296e2?s=50&d=http%3A%2F% . for each & sign you got write & in your example it would be: c91588793296e2?s=50&d=http%3A%2F% Use & for literal ampersands, even in URLs. http://htmlhelp.com/tools/validator/problems.html#amp Replace with & should be: c91588793296e2?s=50&d=http%3A

I am getting a W3V validator error that I can't understand: Line 31, Column 61: Attribute name not allowed on element div at this point.

Should I care about W3C validation?

阅读更多关于 Should I care about W3C validation?

I'm learning AngularJS and I found a simple code like this one: <!DOCTYPE html> <html> <head> <meta charset='utf-8'> <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js"></script> </head> <body ng-app ng-init="name = 'World'"> <h1>Hello, {{name}}!</h1> </body> </html> does not pass W3C validation test, mainly because there are non standard attributes ( ng-app , ng-init ). The question is: should I care about W3C validation of my application? Should I abandon AngularJS? S.Magnaschi You could use the data- html5 attribute which is standard and as far as I know works the

My company is building a website and we had some problems with a JavaScript library not replacing something. We decided to throw our HTML in to the W3C validator and it informed us it's illegal to have a <div> tag inside a <button> tag. <button class="button" type="submit"> <div class="buttonNormalLargeLeft"></div> <div class="buttonNormalLargeCenter">Search Flights</div> <div class="buttonNormalLargeRight"></div> </button> Results in: Line 287, Column 46: Element div not allowed as child of element button in this context. (Suppressing further errors from this subtree.) Edit:

阅读更多关于 What elements can a span tag contain in HTML5?

So I have been a CLI or Cron developer in PHP for most my career and now I am learning why I did not like UI work in school ;) I am dealing with HTML5 validation here and I am not finding an answer to a question that is for curosity. I ran the W3C HTML5 validation on my home page and I got several errors around a div being within a <span> and that is not allowed. I tried changing all <div> within spans to a <p> but recieve pretty much the same error. http://www.w3schools.com/html5/tag_span.asp does not explicitly say what elements are allowed within a <span> and neither does the error from the

How do I escape an ampersand in a javascript string so that the page will validate strict?

I am trying to pass a dataString to to an ajax call using JQuery. In the call, I construct the get parameters and then send them to the php page on the receiving end. The trouble is that the data string has ampersands in them and the HTML strict validator is chocking on it. Here is the code: $(document).ready(function(){ $("input#email").focus(); $('#login_submit').submit(function(){ var username = $('input#email').val(); var password = $('input#password').val(); var remember = $('input#remember').attr("checked"); var dataString = "email="+username+"&password="+password+"&remember="+remember;

阅读更多关于 w3c html validation error - Section lacks heading. Consider using h2-h6 elements to add identifying headings to all sections

I am getting a warning when I try to validate my page in http://validator.w3.org : Section lacks heading. Consider using h2-h6 elements to add identifying headings to all sections. My code is as below : <section id="slider-wrapper-new"> <div class="slider-container-new"> // some code.. </div> </section> How can I remove this error ? Do I compulsory need to add h1 - h6 tags inside section heading ? Either: Add a heading ( h1 , ..., h6 ) tag to your section element. Replace your section element with a div element. Ignore the warning. The message you're seeing is a non-normative usage
