When capturing information for insertion into a database, or use in other processing, it's important to control what the user can enter.Otherwise you can end up with values in the database that have no relation to reality.Reducing the number of components in turn reduces the number of HTTP requests required to render the page. One way to reduce the number of components in the page is to simplify the page's design.But is there a way to build pages with richer content while also achieving fast response times?If not, the input is compared to the regular expression.The expressions use a pre-defined class is returned which enables the form to be submitted.Or when making payments by "paperless" check over the phone or online.
Java Script is also used to enhance forms with additional functionality, such as calendar widgets and the like.In this example, the date fields will only accept input that matches the pattern 'dd/mm/yyyy' (this could just as easily be changed to 'yyyy-mm-dd' or 'mm/dd/yyyy').The time field will allow input starting with 'hh:mm' following by an optional 'am' or 'pm'. The code behind the form is as follows: For each field in the form (first the dates, then the time field), a check is made as to whether the input is blank.tag: content 80% of the end-user response time is spent on the front-end.
Most of this time is tied up in downloading all the components in the page: images, stylesheets, scripts, Flash, etc.
You can play with the form now by trying out the demo.
