Function treats string as single value instead of parsing

I'm using a tags plugin that takes input like this just fine:

$(this).tagHandler({
   assignedTags: [ 'test','from','reddit' ]
});

If however I create a variable named tags that is a string:

tags = "'test','from','reddit'";

And attempt to use it in the function it gets treated as a single string.

$(this).tagHandler({
   assignedTags: [ tags ]
});

Instead of being processed through the function I end up with 'test','from','reddit' as a single tag.

I have a feeling this is a common problem but haven't found the right search phrase to identify the solution.

I'm not sure why you expect the string to be parsed, does the plugin indicate it will do that? My guess is the following might work:

$(this).tagHandler({
   assignedTags: [ tags.split(',') ]
});`

You need to supply an array - the string you've created won't automatically get converted into one:

var tags = ['test', 'from', 'reddit'];
$(this).tagHandler({
   assignedTags: tags
});

If all you have is a string, try:

var str = 'test,from,reddit';
var tags = str.split(',');
$(this).tagHandler({
   assignedTags: tags
});

that's because this is 

 [ 'test','from','reddit' ]

is an array

and what you have does in put a sting into an array you should

what you want is to make an array

 var tags = ['test','from','reddit'];

then add it

$(this).tagHandler({
    assignedTags: tags 
 });

Using an array may work.

tags = new Array('test','from','reddit');
$(this).tagHandler({
   assignedTags: tags
});
