Onchange Dropdown Add Parameters To Url In Inputbox

i am designing affiliate program, in which each user has his own link-code aka tracking url. and i am willing to add extra parameters to it depending on the drop down selection whi

Solution 1:

Try this... It 'll help. *UPDATED WORKING DEMO*

varSourceUrl = "http://www.google.com/?tracker=blah1";
var queryUrl = "";
var landingUrl = "";
$(function() {
  $('#querySelct').on('change', function () {
      if($(this).val() == 0) {
         queryUrl = "";
      } else {
          queryUrl = $(this).val();
      }
      MakeUrl();
      returnfalse;
  });

    $('#landingSelect').on('change', function () {
      if($(this).val() == 0) {
         landingUrl = "";
      } else {
         landingUrl = $(this).val();
      }
     MakeUrl();
     returnfalse;
  });
});

functionMakeUrl() {
    var finalUrl = SourceUrl + queryUrl + landingUrl;
   $('#urlBox').val(finalUrl);
  $('#MyLink').attr('href', finalUrl);
}

Solution 2:

You can use getElementById to get the values from the <select> fields and set them into your textfield.

HTML

<selectid="queryid"><optionvalue="0"label="choose one">choose one</option><optionvalue="&queryid=1"label="option 1">option 1</option><optionvalue="&queryid=2"label="option 2">option 2</option><optionvalue="&queryid=3"label="option 3">option 3</option><optionvalue="&queryid=4"label="option 4">option 4</option><optionvalue="&queryid=5"label="option 5">option 5</option><optionvalue="&queryid=6"label="option 6">option 6</option></select><br><selectid="cid"name="landingpage"><optionvalue="0"label="choose one">choose one</option><optionvalue="&cid=1"label="landing 1">landing 1</option><optionvalue="&cid=2"label="landing 2">landing 2</option></select><inputtype="button"id="change"value="Create URL"onclick="createUrl()" /><br><inputtype="text"id="result"placeholder="placeholder"readonly><br>

JAVASCRIPT

functioncreateUrl() {
    var google = "http://www.google.com/";
    document.getElementById("result").value = google + document.getElementById("queryid").value +  document.getElementById("cid").value;
}

Solution 3:

You could do something like this:

<select id="yourSelect" name="landingpage">
<optionvalue=""label="choose one">choose one</option><optionvalue="www.yourdomain.com&cid=1"label="landing 1">landing 1</option><optionvalue="www.yourdomain.com&cid=2"label="landing 2">landing 2</option>
</select>


$(function(){
  $('#yourSelect').on('change', function () {
      var url = $(this).val();
      if (url) {
          window.location = url;
      }
      returnfalse;
  });
});

Solution 4:

Give selector for selectbox like

var urlToAppend1=$('#nicheId :selected').val();

originalurl='http://www.google.com/?tracker=blah1';
var url='';
url+=originalurl;
url+=urlToAppend;

Solution 5:

Try it.

$(function(){
        $('select').change(function() {

            var arr = newArray();
            $('select option:selected').each(function(){
                var value = $(this).val();
                if(value != "0"){
                    arr.push($(this).val());
                }
            });
            // selected value are now concatenating here.var str = arr.join('');
            alert(str);
        });

    });
