function manageVoting() {
    $("div.votemaincontainer").each(function () {
        // variable Declaration and intialization.
        var myRating = parseInt($(this).find('#[id$=hfMyVote]').val());

    function ajaxcall(a){ // here it's giving error.

EDIT: After improving the code indentation in your question, it appears as though you forgot to close the .each() loop with }); before the closing bracket for the manageVoting() function.

Proper code indentation is extremely helpful.

Also, it doesn’t make too much sense to apply .live() in a loop. You only need to do that once.

Here’s your code with the improvements:

  // Call these once on page load.
  // Note the difference in capitalization in your selectors. Make sure it is
  //    the same in your HTML classes
$('.VoteDownImage').live(click, function () {
    ajaxcall(0);
});
$('.voteupImage').live(click, function () {
    ajaxcall(1);
});

function manageVoting() {
    $("div.votemaincontainer").each(function () {
        // variable Declaration and intialization.
        var myRating = parseInt($(this).find('#[id$=hfMyVote]').val());
        var currentVote = parseInt($(this).find('#[id$=hfCurrentVote]').val());
    });  // closed the .each() loop
}

function ajaxcall(a){ // here it's giving error.
    var questionID = parseInt($(this).find('#[id$=currentquestionId]').val());
    var objectType = 100;
    var previousvote = 2;
    $.ajax({
        url: 'UserControls/Vote/VoteAction.aspx/Voting',
        cache: false,
        type: 'POST',
        data: '{ObjectType: "' + objectType + '", guid: "' + currentGuid + '",previousVote: "' + previousvote + '",vote:"' + a + '"}',
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        success: function (data) {
            var result = eval(data.d);
        }
    });
}
$(function () {
    //    manageVoting();
});

Original answer:

You don’t specify a type for function parameters (or any other variables) in javascript. This is because of loose typing, where any variable can be used to store any type.

This line:

function ajaxcall(int a) 

should be:

function ajaxcall(a)
