object.onmouseover

[Laser Lips]

HI All,

Is it possible to do the following?

object = document.getelementById('something');

object.onmouseover='alert("hi");';

...................


I know that object.onmouseover=function(){alert("hi");} is OK but I
want to do it the first way. Can it be done?

Assigning a function makes sense, assigning a string as you do does not
make sense. So it can be done but is not in any way useful. If you have
a string then you need to create a function from it:
object.onmouseover = new Function('alert("hi");');

Do you need to execute code from a string or is it just an aesthetics
question?

In the latter case, this is not HTML; you don't need to pack all your
code in one line. So (in my humble opinion) this looks just fine:

object.onmouseover = function(){
alert("hi");
};

You can also assign a named function:

function sayHi(){
alert("hi");
}

object.onmouseover = sayHi;


In the former case you'd have to do this:

object.onmouseover = function(){
eval('alert("hi");');
};

Not a good idea unless there's powerful reason.
