Keeping Query Params in a Hashtable

Demonstrates how to use a Chilkat Hashtable to hold query params and re-emit as a query param string.

Note: The ToQueryString method was added in Chilkat v9.5.0.92.

function chilkatExample() {

    var success = false;

    var ht = new chilkat.Hashtable();

    //  Add name/value pairs from an existing query param string where the values are already URL encoded.
    var qp = "txt=this%20is%20a%20test&color=blue&fruits=apples%26oranges";
    success = ht.AddQueryParams(qp);

    //  Add some additional name/value pairs.
    ht.AddStr("name","Jack Sparrow");
    ht.AddStr("movie","Pirates of the Carribean");

    //  Iterate over the hash table to show what we have..

    var keys = new chilkat.StringTable();
    ht.GetKeys(keys);
    var numKeys = keys.Count;
    var key;
    var val;
    var i = 0;
    while (i < numKeys) {
        key = keys.StringAt(i);
        val = ht.LookupStr(key);
        console.log(key + " = " + val);
        i = i+1;
    }

    //  Output for the above loop:

    //  color = blue
    //  name = Jack Sparrow
    //  fruits = apples&oranges
    //  txt = this is a test
    //  movie = Pirates of the Carribean

    //  Get all name/value pairs as a query parm string with values URL encoded
    qp = ht.ToQueryString();
    console.log(qp);

    //  Result:
    //  color=blue&name=Jack%20Sparrow&fruits=apples%26oranges&txt=this%20is%20a%20test&movie=Pirates%20of%20the%20Carribean
