equivalent in jquery
is there any built in function in jquery similar to that of php array_keys(),
.

You will have to define your own function to get the same functionality. Try this:
function arrayKeys(input) {
var output = new Array();
var counter = 0;
for (i in input) {
output[counter++] = i;
}
return output;
}
arrayKeys({"one":1, "two":2, "three":3}); // returns ["one","two","three"]
