HTML - Data Validation
I am new to html programming so i am just wondering if this is at all possible to do in HTML i know in Visual Basic programming you could validate the data the user enters in text fields like IsNumeric etc. to make sure the user only entered in numeric for certain fields. I want to know if there is a way i can do this in HTML
I have seen some example of people using JavaScript to do this type of data validation but i am wondering if there is a way to do it without the help of javascript ??? Similar TutorialsHi Experts, I am designing a webpage where based on the year selection the associated years webtable needs to be displayed in the webpage. Pls give som suggestions and if possible the code on to how to code this using HTML and Jav Script. I know I have to write afunction and then call the fn based on the input.but need your help on this. Thanks, Bsquare So I've got a form with some input text. In addition to the data in the input text I want to send some other data that has already been predetermined on initial page load. How would I declare the other data within the form element? Thanks I have been using my site for some time now and it carries the image name over when you clicked on purchasing the print. It carries it still, but when you submit the form, the image name isnt there and the form errors because the field is blank. Here is the site: www.sthompsonphoto.com I cant seem to figure out why it disappears when you click Submit? Any help would be great! Hi everybody! I have a jsp page with a form and a table. My aim is that when i press the submit button of the form,collect the data and fill the table with it. I am working with J2EE. I have already collected the data in a Java class,but I dont know how to introduce this data into the table. Best Regards! I need help with w3c validator, the validator gives me error for tghe following code: <td background= "http://wwwxyz.com/image-files/top.jpg"✉ You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead). This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information. Can someone suggest me a way to rectify this. Thanks seriously i thought i was pretty decent at html but ive barely done much in recent months/years. http://validator.w3.org/#validate_by_uri and then type: http://www.numyspace.co.uk/~unn_s014557/index.htm i have no idea why there are so many errors. i primarily used dreamweaver for the code so i thought there wouldnt be many problems. Hi! I really need some help trying to figure out why these are errors my website looks perfect, and how can i resolve those errors. http://validator.w3.org/check?uri=http%3A%2F%2Fwww.combbat21.com%2Fnoindex.php&charset=%28detect+automatically%29&doctype=In line&group=0 Thanks!!! http://validator.w3.org/check?uri=ww...%2Faboutme.php any idea how to fix that or even what the problem is? I did close the div, and body, unless im looking at it wrong. thanks I'm trying to validate my html (I've already validated my css), and I keep getting these two errors: there is no attribute "target". ...ref="http://www.freewebs.com" target="_blank">freewebs</a> AND: document type does not allow element "hr" here; missing one of "object", "ins", "del", "map", "button" start-tag. The Navigation: Yay! <br /><hr /><br /> I really don't understand the target="_blank" issue, and I don't know enough about hr's to complain about the second one, so does anyone care to explain? Hello, I am finally getting around the topping off the cake if you will and validating my site. I am having trouble understanding some of the validation errors. What I'll do is link you to the validation and then tell you which ones I am having trouble understanding. http://validator.w3.org/check?uri=http%3A%2F%2Fwww.scubatoo.net%2Findex.php&charset=%28detect+automatically%29&doctype=Inlin e&group=0 And the ones I am having trouble with and can't quite figure out how to fix are, Actually on second thought, I don't quite understand a majority of them. Is there a way I can refrence these problems on a website? Thanks, Ryan Can someone please run the following page through the W3C for me so you can see the errors that come up and tell me if it is important I change them? The errors look like they are all resulting from a javascript I am using. I don't know how to fix it. Im hoping it doesn't matter. thanks My web site main page is basically www.website.com/index.php. I am told that I can validate a php file. So I went to validator.w3.org, plugged in my url and got the error: No DOCTYPE found, and unknown root element. Aborting validation. So I added "<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Strict//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd'> <html xmlns='http://www.w3.org/1999/xhtml' xml:lang='en-us' lang='en-us'>" to the top of my php file and got errors. In a php forum I was tolf to put the <session_start();> at the begining of the file. This took care of the php errors, but still the validator shows No DOCTYPE found, and unknown root element. Aborting validation. Can someone please help me with validation? Here is what the php file looks like now, thanks: Code: <session_start();> <!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Strict//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd'>
<html xmlns='http://www.w3.org/1999/xhtml' xml:lang='en-us' lang='en-us'>

Validation - Just how far should you go? I've sat and started the seemingly longwinded process of validation (xhtml & css) - once you get going it's not as bad as it looks! My question is - just how far should you go? Site Check lists a million things to look at... just where do you stop? is W3C enough? Also how much attention should you be paying to IE's 'Done but with errors on the page' - see attached picture My validated xhtml My validated CSS My Page I have paid a French website company to write a website for me. I validated it using WW3's Validation service and saw loads of errors on every page. The declared doc type is XHTML 1 Trans. It said there were Meta tags in uppercase and not closed properly, nesting errors, tags not allowed and more. The company told me their code was written with Dreamweaver 8 and was correct. They pointed out that if I validated Google's or Firefox's or Microsoft's main page, they will and do show errors. WW3s page validates correctly! So what is the value of WW3 validation and is "bad" code in this case bad? Will it not work in some browsers? For the moment I have no answer to give them. The site, which is half-live (!), is http://www.villa-stbarths.com. I wrote another website myself http://henry-bar.net which has no errors (I corrected them all) and it works fine. Can anyone explain or answer the question "Will a WW3 invalid xhtml wesite work on all browsers"? Henry I am doing a slow process after each section I add make sure it validates, however despite all that it claims Sorry, I am unable to validate this document because its content type is application/octet-stream, which is not currently supported by this service. The Content-Type header is sent by your web server (or web browser if you use the file upload interface) and depends on its configuration. Commonly, web servers will have a mapping of filename extensions (such as ".html") to MIME Content-Type values (such as text/html). That you received this message can mean that your server is not configured correctly, that your file does not have the correct filename extension, or that you are attempting to validate a file type that we do not support yet. In the latter case you should let us know that you need us to support that content type (please include all relevant details, including the URL to the standards document defining the content type) using the instructions on the Feedback Page. However my code shows Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-type" content="text/html; charset=iso-8859-1" /> <meta name="author" content="Mordecai" /> <title>Rigganmore - Land of a Thousand Dreams</title> <meta name="author" content="Mordecai" /> <title>Rigganmore - Land of a Thousand Dreams</title> <link type="text/css" rel="stylesheet" href="stylesheet/general.css" /> <link type="text/css" rel="stylesheet" href="stylesheet/default.css" /> </head> <body> <div id="wrapper"> <div id="header"> </div> </div> </body> </html> Note: the Mime shows text/html not "application/octet-stream" as it claims and charset is there also. Please can someone help me? Hello Webmasters I need someones Help on this I am using this Doctype Type on my Index and every time I try to Valid with w3c and it it keeps comming back with these errors <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> Saying there is no attribute "( height="94" )And No Attribute In( BACKGROUND ) Can One Of You Webmasters Tell Me What Doctype To Use Or How To Fix The Errors.
