DREAMWEAVER CS3 223 Extending Dreamweaver if (theNode.nodeType == Node.ELEMENT_NODE && ¬ theNode.tagName == "SCRIPT"){ document.layers['scriptlayer'].visibility = 'visible'; document.layers['scriptlayer'].document.theForm.¬ scriptCode.value = theNode.innerHTML; document.layers['blanklayer'].visibility = 'hidden'; }else{ document.layers['scriptlayer'].visibility = 'hidden'; document.layers['blanklayer'].visibility = 'visible'; } } 3 Save the file. updateScript(): write back changes The updateScript() function writes back the selected script when an onBlur event occurs in the textarea of the scriptlayer panel. The textarea form element contains the JavaScript code, and the onBlur event occurs when textarea loses input focus. To add the updateScript() function: 1 Open the scriptEditor.htm file that is in the Configuration/Floaters folder. 2 Enter the following code in the header section of the file. /* update the document with any changes made by the user in the textarea */ function updateScript(){ var theDOM = dw.getDocumentDOM(); var theNode = theDOM.getSelectedNode(); theNode.innerHTML = document.layers['scriptlayer'].document.¬ theForm.scriptCode.value; } 3 Save the file. Creating a menu item It is not sufficient to save the Script Editor code in the Configuration/Floaters folder. You must also call either the dw.setFloaterVisibility('scriptEditor',true) function or the dw.toggleFloater('scriptEditor') function to load the floating panel and make it visible. The most obvious place from which to invoke the Script Editor is from the Window menu, which is defined in the menus.xml file. You need to create the menuitem tag that creates an entry for the Script Editor extension on the Window menu, as shown in the following figure:

updateScript(): write back changes
The
updateScript()
function writes back the selected script when an
onBlur
event occurs in the
textarea
of the
scriptlayer
panel. The
textarea
form element contains the JavaScript code, and the
onBlur
event occurs when
textarea
loses input focus.
To add the updateScript() function:
1
Open the scriptEditor.htm file that is in the Configuration/Floaters folder.
2
Enter the following code in the header section of the file.
/* update the document with any changes made by
the user in the textarea */
function updateScript(){
var theDOM = dw.getDocumentDOM();
var theNode = theDOM.getSelectedNode();
theNode.innerHTML = document.layers['scriptlayer'].document.¬
theForm.scriptCode.value;
}
</script>
</head>

Save the file.
Creating a menu item
It is not sufficient to save the Script Editor code in the Configuration/Floaters folder. You must also call either the
dw.setFloaterVisibility('scriptEditor',true)
function or the
dw.toggleFloater('scriptEditor')
function to load the floating panel and make it visible. The most obvious place from which to invoke the Script Editor
is from the Window menu, which is defined in the menus.xml file. You need to create the
menuitem
tag that creates
an entry for the Script Editor extension on the Window menu, as shown in the following figure:
