Get the selected value and create a dynamic table in Javascript

[Marsoni Hutao]

Hi,

I'm making a webpage, where in there is a dropdown and I select that value and hit click.

There is a javascript function containing some variables with the same ID as that of the dropdown values(option id). And there is an array of the same variables declared. Once I hit the click button i want the value that is selected in the dropdown, to be matched with the variable in variable array created and alert the same.

Currently it is not alerting any, if i add an else block, that gets triggered. Below is my JS.

  function addTable() {
   var cancellations = new Array();
   cancellations.push([1, "text"]);
   cancellations.push([2, "text"]);
   cancellations.push([3, "text"]);
   cancellations.push([4, "text"]);

   var changeInfo = new Array();
   changeInfo.push([1, "text"]);
   changeInfo.push([2, "text"]);
   changeInfo.push([3, "text"]);

   var idq = new Array();
   idq.push([1, "text"]);
   idq.push([2, "text"]);
   idq.push([3, "text"]);

   var others = new Array();
   others.push([1, "text"]);
   others.push([2, "text"]);
   others.push([3, "text"]);

   var replace = new Array();
   replace.push([1, "text"]);

   var moreInfo = new Array();
   moreInfo.push([1, "text"]);

   var salesRep = new Array();
   salesRep.push([1, "I would request you to please contact your sales rep  Name: . E-mail id: for more information."]);


   var custReq = new Array();
   custReq.push([1, "text"]);

   var myTableDiv = document.getElementById("myDynamicTable");
   myTableDiv.border = "1";

   var variablesArray = new Array(cancellations, changeInfo, idq, others, replace, moreInfo, salesRep, custReq);

   for (var i = 0; i < variablesArray.length; i++) {
     var dataTerm = document.getElementById('Select2').value;
     if (dataTerm == variablesArray[i].toString()) {
       alert("matched at" + variablesArray[i] + "at i= " + i);
     }
   }
 }

And here is my full code in fiddle.

JSFiddle

please let me know how can i compare and get the correct result in the alert box.

Further i need to create a dynamic table here based on the data.

Thanks,
