In this application I am working on, there are 2 files:
1) .html file which contains the JavaScript code;
2) .js file which contains multiple functions.
In the .html file, there is a line to refer to the .js file.
In my implementation, some of the functions in the .js can be called properly, but some of them returns 'Not defined', which means the function call gets failure to access to the referenced .js file.
For instance, in the .html,
<input id="btn_ImgMap" type="button" name="Street" value="Imagery" class="tabButton" />

I put breakpoints for debugging on both functions above. The 1st function works properly, but the 2nd one does not work ( actually the events: onmouseover, onmouseout and onfocus are not implemented).
How can this bug be solved? Thanks in advance if you can share your experience.

How can this bug be solved?
Probably by correcting the errors in your code. However you need to provide some more details for people to help.

Thanks. See my updated post content.

You haven't shown any of the code that calls those functions.

The code was filtered out somehow. Let me post here:
<div id="div_ImgBtn" class="divButton" style="left: 84px;">
<input id="btn_ImgMap" type="button" name="Street" value="Imagery" class="tabButton" />

also got filtered out some of the content, like: onkeypress="btn_ToggleMap_OnClick('1');" onmouseover="'Image Basemap', 200, 3);"

Solution 1

var myTooltip = function () { ... }

function is a javascript keyword, you cannot use it in this way, it has no meaning. See[^] for full details.

Richard Deeming is right.

I looked all through the w3schools pages to see if that was possible, but found no reference to anonymous functions.

The javascript that you posted did not actually show where you called that function, but since you have deleted it it is no longer clear what your code is doing.
