Info

The second script block links the SpryData.js Spry data library, which is stored in a folder called includes on the server: The Spry data library depends on the XPath library, so it’s important that you always link the XPath library first. The third script block contains the statement that creates the dsSpecials data set. The cafetownsend.xml XML source file is stored in a folder called data on the server: var dsSpecials = new Spry.Data.XMLDataSet("data/cafetownsend.xml", "specials/menu_item"); Note: Remember that JavaScript and XML are case-sensitive languages, so it's important that you make sure that the scripts and column names you specify are capitalized (or not capitalized) appropriately. In JavaScript the new operator is used to create objects. The Spry.Data.XMLDataSet method is a constructor in the Spry data library that creates new Spry data set objects. The constructor takes two parameters: the source of the data ("data/cafetownsend.xml", in this case, a relative URL) and an XPath expression that specifies the node or nodes in the XML to supply the data ("specials/menu_item"). You can also specify an absolute URL as the source of the XML data, as follows: var dsSpecials = new Spry.Data.XMLDataSet("http://www.somesite.com/somefolder/cafetownsend.xml", "specials/menu_item"); SPRY User Guide Note: The URL you decide to use (whether absolute or relative) is subject to the browser’s security model, which means that you can only load data from an XML source that is on the same server domain as the HTML page you’re linking from. You can avoid this limitation by providing a cross-domain service script. For more information, consult your server administrator. In the preceding example, the constructor creates a new dsSpecials Spry data set object. The data set obtains data from the specials/menu_item node (specified by XPath) in the cafetownsend.xml XML file and converts the data to a flattened array of objects and properties, similar to the rows and columns of a table. (For an example of the table, see the beginning of this section.) Each data set maintains the notion of a current row.Bydefault,thecurrentrowissettothefirstrowinthedataset. Later, you can change the current row programmatically by calling the setCurrentRow() method on the data set object. For more information, see “Set or change current row” on page 124. Note: The data set contains no data after you've created it with the new JavaScript operator. To load data into the dataset, first call the data set's loadData() method, which executes a request to load the XML data. Spry regions and detail regions do this automatically for the data sets they depend on, but if you are not using one of these regions, call the loadData() method manually in your page code. This loading is asynchronous, so the data might still be unavailable if you try to access it immediately after calling loadData(). Spry XML Data Set advanced examples Spry XML data sets use the XMLHTTPRequest object to asynchronously load the specified URL. When the XML data arrives, it is actually in two formats: a text format, and a document object model (DOM) tree format. For example, say that you’ve specified “/photos.php?galleryid=2000” as your data source. (This is a path to a web service that retrieves XML data). 93
var dsPhotos = new Spry.Data.XMLDataSet("/photos.php?galleryid=2000", "/gallery/photos/photo"); The following code represents the data as it arrives in text format: John Doe john@doe.com The following example represents the data as it arrives in DOM-tree format. The data set then uses the XPath specified in the constructor to navigate the XML DOM tree to find the particular nodes that represent the data you are interested in. The following code shows data selected with the /gallery/photos/photo XPath, in bold: John Doe john@doe.com SPRY User Guide 94
