Server behaviors
Another approach is to remove the entire tag; typing deletes the attribute. The
resulting text is Link Text.
Share-in-memory JavaScript files
If several HTML files reference a particular JavaScript file, Dreamweaver loads the JavaScript into a central location
where the HTML files can share the same JavaScript source. These files contain the following line:
//SHARE-IN-MEMORY=true
If a JavaScript file has the SHARE-IN-MEMORY directive and an HTML file references it (by using the SCRIPT tag with
the SRC attribute), Dreamweaver loads the JavaScript into a memory location where the code is implicitly included in
all HTML files thereafter.
Note: Because JavaScript files that are loaded into this central location share memory, the files cannot duplicate any
declarations. If a share-in-memory file defines a variable or function and any other JavaScript file defines the same
variable or function, a name conflict occurs. When writing new JavaScript files, be aware of these files and their naming
conventions.
