how to create params({ .. }) ?

Hello,

As part of Ajax I have

var params = ({
mysql_c21answer:c2[1],
mysql_c21correctanswer: correct_answerc2[1],
mysql_c22answer:c2[2],
mysql_c22correctanswer: correct_answerc2[2]
});

but want to create params using a loop like

var details = "";
for (var i = 0; i < 2; ++i) {
var nr = i + 1;
details += "mysql_c2" + nr + "answer:"
+ c2[nr] + ",\n"
+ "mysql_c2" + nr + "correctanswer:"
+ correct_answerc2[nr] + ",\n"
}

now the loop does create the contents as shown inside var params etc
but how do I use the details string to create params correctly?

var params = ({ etc ]); is creating an array or is there more to it
that I am missing?

Thanks

Geoff

Hi,
If I'm not mistaken, you need to create an object (params), don't you?
And supposing c2 and correct_answerc2 are arrays created somewhere in
your code before loop, then:

var params = {}, i = 0;
while (i < 2) {
++i;
params["mysql_c2" + i + "answer"] = "c2[" + i +"]";
params["mysql_c2" + i + "correctanswer"] = "correct_answerc2["+ i
+"]";
}

Incidentally, square bracket notation is covered in the FAQ and notes:
