Understanding "javascript : … ;" inside <a href=" ">
Question by pierr
What is the meanign of javascript:; that is kept inside the href attribute in an link?
Like
<a href="javascript: ... ;">Link</a>
Answer by Starx
IF you need to pass a javascript snippet which needs to run instead of the default behavior of an element then you use this javascript: ; syntax.
For example
<a href="javascript:alert('');">Test</a> <!-- Runs on the click of the link -->
Similarly, you can combine these on other events also, like onclick, onchange etc but this is really not necessary, since you can execute the snippet, directly.
The uses of this, i have seen in years are:
<a href="javascript:void(0);">Test</a><form action="javascript:void(0);">..</form>
