print_r for JavaScript

I was creating a JavaScript flash script early last week, and needed a way to make sure an array was populated correctly. I stumbled across this script on OpenJS, which acts exactly like PHP’s print_r function.

Usage

{code type=js}
dump( my_array );
{/code}

Code

Check out the source code here.

{code type=js}
/**
* Function : dump()
* Arguments: The data – array,hash(associative array),object
* The level – OPTIONAL
* Returns : The textual representation of the array.
* This function was inspired by the print_r function of PHP.
* This will accept some data as the argument and return a
* text that will be a more readable version of the
* array/hash/object that is given.
* Docs: http://www.openjs.com/scripts/others/dump_function_php_print_r.php
*/
function dump(arr,level) {
var dumped_text = “”;
if(!level) level = 0;

//The padding given at the beginning of the line.
var level_padding = “”;
for(var j=0;j \”” + value + “\”\n”;
}
}
} else { //Stings/Chars/Numbers etc.
dumped_text = “===>”+arr+”<===("+typeof(arr)+")";
}
return dumped_text;
}
{/code}
