eval()I should've seen it a while ago.
var jsonA = new Array() ;
var sample_array = [ "foo" , "bar" , "blee" ] ;
for ( var i = 100 ; i <= 290 ; i++ ) {
for ( j in sample_array ) {
var k = i * i * (j+1) ;
k = '"' + k.toString() + '"' ;
jsonA.push( sample_array[j] + i + " : " + k ) ;
}
}
var json = jsonA.join(" , ") ;
x = eval( "( { " + json + " } )" ) ;
That is, create an array. put each name:value pair into the array in the name colon value format. Join 'em with commas. Wrap with curly braces ("This is an Object, JS") and parens ("I'm JS. I'm a language. It's my job to have crazy syntax.") Run eval().
I don't show my JSON step, but it's basically taking the params and pushing them back.
The interesting thing is, with the data I made up here, the top is between 570 and 585 elements. I don't know if that's an HTTP limitation, an eval() limitation or a jQuery limitation, but I know that once I hit that, the code flakes. Which is interesting.
