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.
