Q. How might I get the keys of a javaScript associative array?
A. This little function does the same thing as the perl keys builtin function.
function keys(h) {
var i, a = [];
for (i in h) a.push(i);
return a;
}
function exampleUse() {
var months = { jan: 31, feb: 28, mar: 31, apr: 30, may: 31, jun: 30, jul: 31, aug: 31, sep: 30, oct: 31, nov: 30, dec: 31 };
dump(keys(months));
}
