  passing VB.net array to javascript using ClientScript class

  Dec 04, 2012 03:57 PM|LINK

  I am trying to use the ASP.net class ClientScript to pass an array to my aspx page. I have succesfully completed an earlier sample to do this (code sample below). But a new routine is not working. The difference is the ClientScript class.

  Error states that "routeCoords is undefined"

  my java code is...

  function newTest() { 

  var myArray= [ , ];

  var n= 0;

  var recCount= routeCoords.length/ 15;

  for (var i= 0; i< recCount; i++) {

    for (var s= 0; s< 15; s++) { 

        myArray[i, s] = routeCoords[n];

        n++;

        alert(myArray[s], [i]); 

      }

   }

  }

  vb.net to register the script....

  ' arrylist

   For p= 0 To arryLst.Count- 1

         Page.ClientScript.RegisterArrayDeclaration("routeCoords", arryLst(p))

   Next

   Dim strScriptAs String = "newTest();"

   ClientScript.RegisterStartupScript(GetType(Page), "newTest", strScript.ToString, True)

  the array is correctly populating in vb.net

  this is the routine from the sample that is working...

  VB.net code:

  For s= 0 To arryLst.Count- 1

       Page.ClientScript.RegisterArrayDeclaration("parmTypeAry", arryLst(s))

  Next

  JAVA code:

  // Createand ElementObject of type"option"

  var opt= document.createElement("option");

  //Add the option element to the select item

   listID.options.add(opt); 

   //Reading Element From Array 

   opt.text = parmTypeAry[s];

  which populates a dropdownlist box.

  routeCoords[n] - Where is n defined?

  I don't understand why after you help someone, they don't mark your post as the answer. What's up with that???

  ok, sorry I missed that.

  What about this section, is it not overriding the routeCoords each time?

  For p=0 To arryLst.Count-1

         Page.ClientScript.RegisterArrayDeclaration("routeCoords", arryLst(p))

  Next

  No, that loop populates the array and makes it available to javascript on the page. I have the issue fixed and will post the solution soon.
