  55. 55. Spry Effects var fadeEffect= new Spry.Effect.Fade(’myElId', {toggle:true}); fadeEffect.start(); Simple Interface Chaining via Observers unFade = function(element,effect) { fadeEffect= new Spry.Effect.Fade(,{toggle:true,finish:unFade}); fadeEffect.start(); }; var fadeEffect= new Spry.Effect.Fade('thanksDiv',{toggle:true,finish:unFade}); fadeEffect.start(); var fadeEffect2= new Spry.Effect.Fade(’myElId', {duration:2000,from:0,to:100}); fadeEffect2.start(); var growEfct= new Spry.Effect.Grow(’myElId', {useCSSBox:true, growCenter:true}); growEfct.start();

  59. 59. Spry For Dreamweaver 4. Spry Datasets
  60. 60. Spry Datasets Transactional JavaScript Framework Stateful Spry Framework XML JSON HTML Hands off.. CSV/TSV
  61. 61. Types of Datasets <ul><ul><li>XML </li></ul></ul><ul><ul><li>HTML </li></ul></ul><ul><ul><li>JSON </li></ul></ul><ul><ul><li>Paged View </li></ul></ul><ul><ul><li>Nested (master/detail) </li></ul></ul>

Spry Datasets <script type=&quot;text/javascript&quot; src=&quot;includes/xpath.js&quot;></script> <script type=&quot;text/javascript&quot; src=&quot;includes/SpryData.js&quot;></script> Creating an XML Dataset Create a View <div spry:region=“products”> <h2 spry:sort=“ProductName”>Sort by Name</h2> <h2 spry:sort=“UnitPrice”>Sort by Price</h2> <div spry:repeat=“products”> <p>{ProductName} – {UnitPrice}</p> </div> </div> var products = new Spry.Data.XMLDataSet( &quot;products.xml&quot;, &quot;dataroot/Products&quot;);
  63. 63. Spry Datasets <div id=&quot;images_div&quot; spry:region=&quot;imageDS&quot; > <div spry:repeat=&quot;imageDS&quot; class=&quot;thumbHolder&quot; id=&quot;dv_{ds_RowID}&quot; onClick=&quot;imageDS.setCurrentRowNumber({ds_RowID})” > <img src=&quot;images/{ImageFile}&quot; id=&quot;img_{ds_RowID}&quot; /> </div> </div> <div id=&quot;Specials_Detail_DIV&quot; spry:detailregion=&quot;imageDS” > <img src=&quot;images/{ImageFile}&quot; id=&quot;imgbig_{ds_RowID}&quot; /><br /> <h2>{ImageName}</h2> <p><b>{DateTaken}</b> - {ImageDescription}</p> </div> Image Gallery Drill-Down
  64. 64. Spry Data Set API var myFilterFunc = function(dataSet, row, rowNumber) { // Filter out all rows with paths that begin // with the letter 's'. if (row[&quot;@path&quot;].search(/^s/) != -1) return row; // Return the row to keep it in the data set. return null; // Return null to remove the row from the data set. } // Filter the data. dsPhotos.filterData(myFilterFunc); // Remove the filter. dsPhotos.filterData(null); Programmatic Filter
