Muiltple Google Blog Searches on Load - Pure Javascript Issue

I am referring to the blog search using Google API, exactly as shown here
http://code.google.com/apis/ajax/playground/?exp=maps#add_results_pagination

It works well, but I'd like to have six different queries over the same page. So I'd definitely have to call six different onLoad events.

For that, I use

    function addLoadEvent(func) {
        var oldonload = window.onload;
        if (typeof window.onload != 'function') {
            window.onload = func;
        } else {
            window.onload = function() {
                if (oldonload) {
                    oldonload();
                }
                func();
            }
        }
    }

    addLoadEvent(content);
    addLoadEvent(beauty);
    addLoadEvent(problems);
    addLoadEvent(views);
    addLoadEvent(development);

Code (markup):

the following script above, works fine for loading multiple onload events.

For our understanding, let's take two searches for now and their correspond javascript code - hope you understand the issue by now.

  // Set a callback to call your code when the page loads
    google.setOnLoadCallback(onLoad);

    function addPaginationLinksContent() {
        // Add pagination
        var cursor = blogSearch.cursor;
        var curPage = cursor.currentPageIndex; // check what page the app is on
        var pagesDiv = document.createElement('div');
        for (var i = 0; i < cursor.pages.length; i++) {
            var page = cursor.pages[i];
            if (curPage == i) { // if we are on the curPage, then don't make a link
                var label = document.createTextNode(' ' + page.label + ' ');
                pagesDiv.appendChild(label);
            } else {

                // If we aren't on the current page, then we want a link to this page.
                // So we create a link that calls the gotoPage() method on the searcher.
                var link = document.createElement('a');
                link.href = 'javascript:blogSearch.gotoPage(' + i + ');';
                link.innerHTML = page.label;
                link.style.marginRight = '2px';
                pagesDiv.appendChild(link);
            }
        }
        var contentDiv = document.getElementById('content');
        contentDiv.appendChild(pagesDiv);
    }

    function searchCompleteContent() {
        // Check that we got results
        document.getElementById('content').innerHTML = '';
        if (blogSearch.results && blogSearch.results.length > 0) {
            for (var i = 0; i < blogSearch.results.length; i++) {

                // Create HTML elements for search results
                var p = document.createElement('p');
                var a = document.createElement('a');
                a.href = blogSearch.results[i].postUrl;
                a.innerHTML = blogSearch.results[i].title;

                // Append search results to the HTML nodes
                p.appendChild(a);
                document.getElementById('content').appendChild(p);
            }
        }
        addPaginationLinksContent(blogSearch);
    }
    
    
    function content() {

        // Create a BlogSearch instance.
        blogSearch = new google.search.BlogSearch();

        // Set searchComplete as the callback function when a search is complete.  The
        // blogSearch object will have results in it.
        blogSearch.setSearchCompleteCallback(this, searchCompleteContent, null);


        // Return up to eight results
        blogSearch.setResultSetSize(google.search.Search.LARGE_RESULTSET);
