Writing the JavaScript code
Next, you create the JavaScript file that contains any functions that are specific to your stand-
alone report.
To create the JavaScript file:
1. Create the Listimages.js file in the Configuration/Commands folder with the following
code:
function stdaloneresultwin()
{
var curDOM = dw.getDocumentDOM("document");
var tagList = curDOM.getElementsByTagName('img');
var imgfilename;
var iOffset = 0;
var iLineNumber = 0;
var resWin = dw.createResultsWindow("Images in File", ¬
["Line", "Image"]);
for (var i=0; i < tagList.length; i++)
{
// Get the name of the source file.
imgfilename = tagList[i].getAttribute('src');
// Get the character offset from the start of the file
// to the start of the img tag.
iOffset = curDOM.nodeToOffsets(curDOM.images[i]);
// Based on the offset, figure out what line in the file
// the img tag is on.
iLineNumber = curDOM.getLineFromOffset(iOffset[0]);
// As long as the src attribute specifies a file name,
if (imgfilename != null)
{ // display the line number, and image path.
resWin.addItem(resWin, "0", "Images in Current File", null, ¬
null, null, [iLineNumber, imgfilename]);
}
}
return;
}
// add buttons to dialog
function commandButtons()
{
return new Array("OK", "stdaloneresultwin()", "Cancel",
"window.close()");
}
2. Save the file as Listimages.js in the Configuration/Commands folder.
