Check if Current user exist in sharepoint group in a site

I have multiple permission groups created on the site and I have a form displaying the drop down list of the group names. This is a choice field.

Before submitting the form, I would like to check if the current user , based on whatever he selects in the dropdownlist, I would like to check if the user exist in that group before the user clicks the submit.

I have the folowing code to find  the current user on the SP site. But i dont know how to modify the code to find if the current user exist in the permission group?  

<script type="text/javascript" language="javascript">
var context = null;
    var web = null;
    var currentUser = null;
    function getWebUserData() {
        context = new SP.ClientContext.get_current();
        web = context.get_web();
        currentUser = web.get_currentUser();
        currentUser.retrieve();
        context.load(web);
        context.executeQueryAsync(Function.createDelegate(this, this.onSuccessMethod), Function.createDelegate(this, this.onFailureMethod));
    }
    function onSuccessMethod(sender, args) {
        var userObject = web.get_currentUser();
        alert('User name:' + userObject.get_title() + '\n Login Name:' + userObject.get_loginName());
    }
    function onFailureMethod(sender, args) {
        alert('request failed ' + args.get_message() + '\n' + args.get_stackTrace());
    }
    ExecuteOrDelayUntilScriptLoaded(getWebUserData, "sp.js");
    </script>

Hi,
perhaps the usage of SPServices would make this easier:

Hi,
<script language="javascript" type="text/javascript">
$(document).ready(function() {
var groupName;

 $().SPServices({  
      operation: "GetGroupCollectionFromUser",  
      userLoginName: $().SPServices.SPGetCurrentUser(),  
      async: false,  
      completefunc: function(xData, Status) {
        //if current user is not a member of this group...  
        if($(xData.responseXML).find("Group[Name=' a group"]").length != 1)  
        {  
              //...disable the following fields
             alert("Please check the activity you have selected");
             $("input[Title='btnSave']").prop("disabled", "disabled");
              }  
      }  
    });  
});

</script>

The above code works if i have find for 1 group.  But based on the drop down selection, I have to check if that user exist in that group.  Can you please guide me on how to write that code?.

Something like this
isGroupMember("myGroupName", function(result){
if(result){
//code here
}
});

function isGroupMember(groupName, callback)
{
$().SPServices({
operation: "GetGroupCollectionFromUser",
userLoginName: $().SPServices.SPGetCurrentUser(),
async: true,
completefunc: function(xData, Status) {
callback( !!($(xData.responseXML).find("Group[Name='" + groupName + "']").length) ); /* returns bool */
}
});
};

I have an drop down field and based on the field selected, I have to assign that value to a variable and that variable needs to be accessed as groupName.

Please help to rewrite the code.
