String to Array with evaluate() fails

How does one convert a string to an array

<cfscript>
    stResult = {    strData = "[1,2,3,4,5,6]"
                 ,  arInstant = [1,2,3,4,5,6]
               };

    //stResult.arData = evaluate(stResult.strData);  // this does not work
    //stResult.arData = evaluate("#stResult.strData#"); // nor does this

    writedump(stResult);
</cfscript>

I am trying to get something that looks like arInstant.

Is there a better way than striping the [], converting to a list, then converting to an array?

Solution

  • evaluate() should generally be avoided (ref: 1, 2, 3). How about trying:

    stResult.arData = ListToArray(stResult.strData, "[],");

    This is treating the whole string as a list, with possible delimiters of [ and ] and ,

    It should give you an array with 6 elements in it.

    Of course, it seems that your stResult.arInstant already has what you need... what are you trying to do?
