Javascript save variable to array and get values in a loop

Question

I have JavaScript code like this:

var arrayku = new Array();
for (var i = 0; i < sURLVariables.length; i++)
{
  var sParameterName = sURLVariables[i].split('=');
  if (sParameterName[0] == sParam)
  {
    return [i, sParameterName[0], sParameterName[1]]; //i is id, sParameterName[0] is first 2nd param, sParameterName[1] is third param
  }
}

The Question is how to:

Put variable i, sParameterName[0], sParameterName[1] into array of key and value and I want variable i as the key.
How to get all value of arrayku in a loop?

Devi, your question isn't clear. By "array of key and value" do you mean an Object, which is what Javascript uses for an associative array? Why can't you get all the values of arrayku the same way you get all the values of sURLVariables? — Michael Lorton

Use push() to add the elements to the array in the loop.

var arrayku = new Array();
for (var i = 0; i < sURLVariables.length; i++) {
  var sParameterName = sURLVariables[i].split('=');
  if (sParameterName[0] == sParam) {
    arrayku.push( [i, sParameterName[0], sParameterName[1]]); //i is id, sParameterName[0] is first 2nd param, sParameterName[1] is third param
  }
}
console.log(arrayku);

hi epascarello, thanks for the answer, how to access and display arrayku?

It is a array of objects.... You access it like an Array? Not sure how you want to display it...
