This example shows the use of the drag shim when dragging nodes over other troublesome nodes.
Try dragging the proxy element over the iframe below, in most browsers this will not happen. Now click the Turn Shim On
button and drag again. Now you can drag over the iframe.
You can see the shim by clicking the Turn Debugging On
button while using the shim, the default for this example is that the shim is off.
Full source code for this example.
YUI().use('dd-ddm', 'dd-drag', 'dd-proxy', function(Y) { //Toggling the buttons Y.one('#shim').on('click', function(e) { var value = e.target.get('value'); if (value == 'off' || value == 'Turn Shim On') { dd.set('useShim', true); e.target.set('value', 'on'); e.target.set('innerHTML', 'Turn Shim Off'); Y.one('#debugShim').set('disabled', false); } else { dd.set('useShim', false); e.target.set('value', 'off'); e.target.set('innerHTML', 'Turn Shim On'); Y.one('#debugShim').set('disabled', true); } }); Y.one('#debugShim').on('click', function(e) { var value = e.target.get('value'); if (value == 'off' || value == 'Turn Debugging On') { Y.DD.DDM._debugShim = true; e.target.set('value', 'on'); e.target.set('innerHTML', 'Turn Debugging Off'); } else { Y.DD.DDM._debugShim = false; e.target.set('value', 'off'); e.target.set('innerHTML', 'Turn Debugging On'); } }); var dd = new Y.DD.Drag({ //Selector of the node to make draggable node: '#demo', useShim: false }).plug(Y.Plugin.DDProxy, { offsetNode: false, resizeFrame: false }); dd.on('drag:start', function() { this.get('dragNode').setStyles({ height: '20px', width: '100px', backgroundColor: 'blue', color: '#fff' }); this.get('dragNode').set('innerHTML', 'Custom Proxy'); this.deltaXY = [this.deltaXY[0] - 20, this.deltaXY[1] - 20]; }); });
