ajax InvalidCharacterError

Question

I'm not familiar with ajax and I'm debugging in IE10 and got an error InvalidCharacterError on this block of code. When I set it to the edge mode it throws an Invalid Argument Error .

jQuery.ajax({
    async: false,
    type: 'POST',
    url: url,
    dataType: 'html',
    data: ({copyEventId : copyEventId}),
    success: function(data){
        $j('#Tab1').html(data);
        initializeWizardState();
        bindQuestionFieldEvents(1);
    },
    error: function(xmlHttpResponse, textStatus, errorThrown){
        alert('ERROR!! status: ' + textStatus);
    },
    cache: false
});

Try this
jQuery.ajax({
    async: false,
    type: 'POST',
    url: url,
    dataType: 'html',
    data: {"copyEventId" : copyEventId},
    success: function(data){
        $j('#Tab1').html(data);
        initializeWizardState();
        bindQuestionFieldEvents(1);
    },
    error: function(xmlHttpResponse, textStatus, errorThrown){
        alert('ERROR!! status: ' + textStatus);
    },
    cache: false
});
