How to return JSON array instead of text for specific column

[SamehMahmoud]

I want to return a JSON array from an extractor like this:

`

10 : function(cellIndex , $cell){
                    var prlArray = [];
                    $cell.find('select option').each(function(){
                        //alert(this.value);
                        prlArray.push(this.value);
                    });
                    return JSON.parse(prlArray.toString());
                }

`

This extractor is causing error in because of "return JSON.parse(prlArray.toString());" thanks in advance

does this not work?

function(cellIndex , $cell){
    var prlArray = [];
    $cell.find('select option').each(function(){
        //alert(this.value);
        prlArray.push(this.value);
    });
    return prlArray;
}

It does, but it is concatenated to the rest data as String not array like this : { parallelActions: "8,2,3"} but what i need is to be like this: {parallelActions : [8,2,3]}

Just looked at the code. It will always convert whatever you give it into a string. As far as I know there is no way around this in the current version.

You could process this.value before pushing it into the prlArray.

Maybe you can try using this simple jQuery plugin called nVal()... use $(this).nVal() and it will return an array of numbers.

@Mottie I think the problem is that anything returned from the extractor function is automatically converted to a string by the $.trim function: https://github.com/lightswitch05/table-to-json/blob/master/src/jquery.tabletojson.js#L55

@SamehMahmoud I @lightswitch05 I submitted a PR #37 which should be able to fix this issue.
