Javascript for validating email updating firmware on canon 7d

When all fields have been validated the form will be able to be submitted.Samples of the XML files returned in each case can be found below.See the article Web Services using XMLHttp Request (Ajax) for details on all avaiable commands and their parameters.

My feeling is that this article already describes how to generate the XMLHttp Request (Ajax) request, passing GET or POST variables to a server-side script using our Java Script class, and the related article referred to above provides a complementary PHP class for generating XML responses, so really all that's left is basic programming to process the incoming variables and generate the relevant XML response.We won't go into the details of how the script actually does this as that's been covered elsewhere (see links below).For an Age input value of 12 the validation script returns the following XML document: s of elements in the HTML document.The other two files (represented in the graphic in green) can be downloaded or copied from this site and included from your files as indicated.In this particular example, and with form validation in general, the advantage over other techniques (Java Script and/or server-side validation) is that we can make use of server-side technologies to perform more complex validation and present real-time feedback to the user without reloading the page.For those having trouble getting started, here's a walk-through: Hopefully that solves the problems some people have had implementing the code.A few people have commented that this is all a bit confusing when it comes to implementing it on your own website.The 'empty comment" in the DIV is just a place-holder - required in some older browsers when a DIV is empty, but needs later to be referenced by a script.When we call the function we pass three parameters: the method (in this case 'check Email' or 'check Age') to use for testing, the value to test, and the id of the input field (target).The target value is also used to work out the id of the relevant checkbox and the DIV that will display feedback.accepts the three variables (method, value, target) in POST format and uses them to generate an appropriate response in XML format.
