Does inline Javascript code like this below:
<div onclick='javascript:some_function();'></div>
grow up web page’s loading time in any way?
Yes, it does.
The browser must fire up a separate Javascript parser for each attribute.
It is more efficient to bind the events to functions using
attachEvent/addEventHandler, or, more easily, jQuery.On an unrelated note, you shouldn’t use
javascript:in an event attribute (aside from the fact that you shouldn’t use event attributes at all). It’s just an unused label.In
hrefattributes, thejavascript:protocol allows you to create a URI that executes Javascript. However, event attributes take a string of Javascript code, not a URI.
