Populating BDC fields from a query string in MOSS (Microsoft Office Sharepoint Server) 2007

Whomever tried to populate a MOSS (Microsoft Office Sharepoint Server) form field using Javascript noticed that it is far from being straightforward. The secret is in the undocumented core.js After a client’s request I was able to come up with a not so-intrusive Javascript solution.

You have to open the site in Sharepoint Designer, navigate to the list you want (in my example I used a list called “Public Details”), look for a spot in the html code and copy the Javascript code below to both EditForm.aspx and NewForm.aspx.

For each list in your site there will be a folder. For instance, let’s say you have a list called Public Details. In Sharepoint Designer you should edit files under site\Lists\Public Details as shown below (be aware these pages will be unghosted after that):


To test the application, just add the query string ?BDC=<value> to the url (eg. http://portal/Lists/Public+Details.aspx?BDC=123). See code below:


<script type=”text/javascript” language=”javascript” for=”window” event=”onload”>

var elems = document.getElementsByTagName(“DIV”);
var bdcString=””;

var queryString = document.location.search.split(“&”);

for (var i=0;i<queryString.length;i++) {
if ((queryString[i].split(“=”)[0]==”BDC”) || (queryString[i].split(“=”)[0]==”?BDC”)) bdcString=queryString[i].split(“=”)[1];

if(bdcString == “”) return;

for (var i=0;i<elems.length;i++) {

if (elems[i].id.indexOf(“_upLevelDiv”) > 1)
        var subs = elems[i].id.substring(0,elems[i].id.indexOf(“_upLevelDiv”));
        var upLevel = document.getElementById(subs+”_upLevelDiv”);
        if(upLevel == null)
         alert(“error Up Level is invalid: “+subs+”\n”+upLevel);
        var downlevel=document.getElementById(getSubControlID(subs, g_EntityEditorDownLevelId));
        downlevel.value = bdcString;
        var editor=document.getElementById(subs)
        SetInnerText(upLevel, bdcString);

    Could you please let me know, How to access data from BDC in javascript?

  2. Try this (I haven’t tested yet). This should display the content of all BDC fields in a window:

    <script type="text/javascript" language="javascript" for="window" event="onload">

    var elems = document.getElementsByTagName("DIV");

    for (var i=0;i<elems.length;i++) {

    if (elems[i].id.indexOf("_upLevelDiv") > 1)


         var subs = elems[i].id.substring(0,elems[i].id.indexOf("_upLevelDiv"));

         var upLevel = document.getElementById(subs+"_upLevelDiv");

         if(upLevel == null)


          alert("error Up Level is invalid: "+subs+"n"+upLevel);



         alert("BDC content is "+upLevel.innerText);




    Let me know if it works.
