A Javascript function is said as "Not a function"

Hi ,

When i am calling a javascript function , on Onclick of Button click , an error gets displayed on to Fire Bug console , displaying it as "Not a Function "
please find the scren shot attached .

Please solve this issue . thanks .

In addition to using code tags, making sure that the code is properly formatted might get more people to look at it.

If you're defining functions inside the script tags, then the script tag should not also have a src specified. According to W3C's recommendation for script in HTML 4.01...

The script may be defined within the contents of the SCRIPT element or in an external file. If the src attribute is not set, user agents must interpret the contents of the element as the script. If the src has a URI value, user agents must ignore the element's contents and retrieve the script via the URI.

But you can do both...

<script type="text/javascript">
//define here
</script>

Thanks Marc , at first i followed this approach only , but later chnaged it (Just want to say that not working either ways)

making sure that the code is properly formatted might get more people to look at it.

If its a Java Code , i would have entered Ctrl + Shift + F on Eclipse IDE to format the code , is there any way or open source plugins to format JSP / HTML Pages to format the code ??

and anyway still the problem persists

any help ??

I found the error , its strange , but its fact :

Just Replaced the onclicks function name from myButton to myButtons , may be myButton is a reserved word .

No, it is not a reserved word.

Can't say without knowing what's in the js file. But if that's what fixed it, my guess is you've defined myButton as a global var.

For example, if you did something like this in your js file...

...and then tried to add...

...that would produce a "not a function" error (it does in Safari anyway). Changing the function name would put a bandage on the situation, but you would still have some messy code.

Again, just a guess.

Some browsers let you reference elements by their id

so instead of

you can do [and should never do]

So it is just a name collision.

Use namespaces in your code and you will not have these issues.
