Atlas provides a powerful validation framework for your client-side data. This validation is centered on validation controls, which, when configured with the control, allow for the automatic and declarative validation of the data that is entered into these controls. You looked at validating the presence of the data using the requiredFieldValidator where if the data hasn t been entered, you want to take an action to inform the user. Additionally, you looked at the typeValidator, which can inspect the data for a specific type. This is particularly useful for filtering input boxes (which are free-format text boxes) for numeric values. Consider the difficulty of this in normal circumstances where you would have to evaluate the contents of the box and use them if they were greater than zero! Finally, you looked at the range validator, which is used for numeric values and which trips an error if the data falls outside the range. These are also useful for many common tasks and mean you don t need to write any code on either the server or the client. Another validator that is available is the regExValidator, which validates the input data against a regular expression. Regular expressions are similar to wildcard specifiers but are much more powerful and flexible. They are used to specify search criteria. So, for example, if you want to match a field against a valid U.S. telephone number, you would use this regular expression: /\(\d{3}\)(\ )\d{3}-\d{4}/ If you are not familiar with regular expressions, this probably looks a little strange. However, regular expressions are incredibly useful for validating data against a fixed structure such as a telephone number or an email address. You can find a great resource on regular expressions at http:// www.regular-expressions.info/.

Finally, AppleScript also supports custom validators. A custom validator is a function written in JavaScript. This function should accept an eventArgs variable. After performing your custom validation, you should call the set_IsValid function on this with true or false as a parameter. Here s an example: function onValidateValue(sender, eventArgs) { var names = [ 'Engineer', 'Manager', 'Performer', 'Construction Engineer', 'Chef']; var valid = names.contains(eventArgs.get_value()); eventArgs.set_isValid(valid); } This function contains a list of valid names. The eventArgs sent to the function contains the data that is being validated. This is checked against the string of valid values. If it is found, the validation is successful, and the valid var will be true; otherwise, it will be false. At the end of the function, the eventArgs will have its isValid set with this value, and the custom validation will be complete.

Many controls support click events that you can use to handle user input. But not everything has a click event that will allow you to specify a handler. If you want to associate an action with a click on an element that doesn t support this, you can use the click behavior. So, for example, you can associate a click behavior with a piece of text on the page by creating a label out of it and applying the click behavior to that. You can see this example in Figure 5-16.

The HTML for this page is as follows: <div class="description"> <h3><u>Example 8: Click behavior</u></h3> <div id="panel">The hide and show elements here are not buttons -- they are HTML spans, but they can support clicking through use of the click behavior on their associated Atlas labels.</div> <br /> <span id="hideLabel" class="buttonstyle2">Hide</span>  <span id="showLabel" class="buttonstyle2">Show</span> </div> You can see that the Hide text and the Show text are implemented as <span> elements and are given the IDs hideLabel and showLabel, respectively. Keep these in mind as you look at the Atlas Script for this page, shown here: <script type="text/xml-script"> <page xmlns:script="http://schemas.microsoft.com/xml-script/2005"> <components> <control targetElement="panel" cssClass="start" /> <label targetElement="hideLabel"> <behaviors> <clickBehavior> <click> <setProperty target="panel" property="visible" value="false" /> </click> </clickBehavior> </behaviors> </label> <label targetElement="showLabel"> <behaviors> <clickBehavior> <click> <setProperty target="panel" property="visible" value="true" /> </click> </clickBehavior> </behaviors> </label> </components> </page> </script>
