Uncaught SyntaxError: Unexpected token var

Solution 1

Count the open parentheses on this line:

loadarea.empty( ).append($.thumbnailviewer2.buildimage($, $anchor, s, options)
              ^ ^       ^                             ^                      ^
              1 0       1                             2                      1

Add another closing paren; the parser thinks you're still specifying arguments to the append() function, and the var keyword is invalid in this context.

Also, use semicolons. If not for your sake, do it for Douglas' health.

I had a similar error message in the console with the minifier parsing my javascript source code. I found that using // comments like so always interrupted the minification process, and gave me an error in the console. Therefore i switched all /* comments */ like so. MDN Javascript Comments And immediately everything parsed as expected. Hope it helps.

I have an error Uncaught SyntaxError: Unexpected token var displayed between (1) and (2) its a very odd error and it doesn't make sense at all.

if ($hiddenimage.length==0) { //if this is the first time moving over or clicking on the anchor link
    var $hiddenimage=$('<img src="'+this.href+'" />').appendTo($hiddenimagediv) //populate hidden div with enlarged image
    $hiddenimage.bind('loadevt', function(e){ //when enlarged image has fully loaded
        loadarea.empty().append($.thumbnailviewer2.buildimage($, $anchor, s, options)
        (1) - var $targetimage=$.thumbnailviewer2.buildimage($, $anchor, s, options) //create reference actual enlarged image
        (2) - $loadarea.empty().append($targetimage) //show enlarged image
        $.thumbnailviewer2.showimage($targetimage, s)
    })

The error is due to an unclosed parentheses .

Thanks a lot I cant believe it was that easy, I didn't know you could use semicolons LOL

Use semicolons, and use an editor that will show you matching parens.

This is a big problem and can cause code in production not run at all.

Can't verify for production, may very well be. Voted on cdhowie's answer 👍
