Example

The following example adds a handler to the Vwa.shapeselectionchanged event. When the event is raised, the code sample gets the hyperlinks applied to the shape that raised the event and then displays them in the Content Editor Web Part.

<script type="text/javascript">

document.write("Hyperlinks contained in this shape:");
document.write("<div id='shapelinks'></div>");

// Declare the global variables for the Visio Web Access web part, the active page in the web part,
// the shapes on the active page, and the <div> tag in the Content Editor Web Part.
var vwaControl;
var vwaPage;
var vwaShapes;
var linkList;

// Add a handler to the AJAX Sys.Application.load event.
Sys.Application.add_load(onApplicationLoad)

// Capture a reference to the current session of the Visio Web Access Web Part.
function onApplicationLoad() {
    try{
            vwaControl= new Vwa.VwaControl(getVWAWebPartID());
            vwaControl.addHandler("diagramcomplete", onDiagramComplete);
    }
    catch(err){
        alert(err);
    }
}

// Search the SharePoint page to get the WebPartID# for the Visio Web Access Web Part.
function getVWAWebPartID() {
    
    // Get a NodesList of all the div tags on the page. 
    var divArray = document.getElementsByTagName("div");
    var webPartElementID;
    
    // Iterate through the NodesList to get the node with the class attribute "VisioWebAccess."
    for (var i = 0; i < divArray.length; i++) {
        var node = divArray[i];
        
        // Return the first instance of the Visio Web Access Web Part.
        if (node.className == "VisioWebAccess") {
            webPartElementID = node.parentNode.parentNode.id;
            break;
        }
    }
    return webPartElementID;
}

// Capture references to global variables and add handler functions to events.
function onDiagramComplete(){
    try{
        // Set the vwaPage and vwaShapes variables to the active page and the shapes collection on that page, respectively.
        vwaPage = vwaControl.getActivePage();
        vwaShapes = vwaPage.getShapes();
        linkList = document.getElementById("shapelinks");

        // Remove the handler from the shape selection changed event and then add it back to the event.
        vwaControl.removeHandler("shapeselectionchanged", onShapeSelectionChanged);
        vwaControl.addHandler("shapeselectionchanged", onShapeSelectionChanged);
