Again I am writing some programming thing on this blog after a longtime.
Eval(eval()) function is an advanced function in javascript which may look silly and most people may overlook it, but it is a really a powerful thing that javascript provides.
We had a scenario where we have to pass the applet object dynamically so that we can manipulate its param.
document.appletName.getChartObject().getTitle());
where appletName is a variable which stores appletname. So we started banging our heads on that. First option was creating an array variable to store the applets. But that would be too complicated. Then I came across this function.
So we used
eval("document."+appletName+".getChartObject().getTitle()");
and tadaaaah...We got the desired result.
The eval() function evaluates a string and executes it as if it was script code. Cool na...
