使用jQuery超出了最大调用堆栈大小

Question

我的jQuery出错，我不明白为什么......

我的错误：未捕获RangeError：超出最大调用堆栈大小

我的代码：

“getSelected”函数返回一个对象，“editeTextOfSelectedCase”更新“getSelected”对象......

        var removeCaseToEditableMode = function removeCaseToEditableMode($case){
            getSelectedCase().isEditable = false;
            $case.attr('contenteditable', false);
            $case.attr('id', '');
            editeTextOfSelectedCase($case);
            var $rightCase = getSelectedCase().$rightCase; // error with these two last lines ...
            selectCase($rightCase);
        };

编辑＃2：

        var getSelectedCase = function getSelectedCase(){
            var $selectedCaseFound = false;
            $.each(cases, function(index, value){
                if( value.isSelected ){
                    $selectedCaseFound = value;
                }
            });
            return $selectedCaseFound;
        };

        var editeTextOfSelectedCase = function editeTextOfSelectedCase($case){
            getSelectedCase().preventText = getSelectedCase().newText;
            getSelectedCase().newText = $case.text();
        };

        var selectCase = function selectCase($case){
            unselectCase();
            cases[$case.data('index')].isSelected = true;
            setCssOfCase($case);
        };

        var unselectCase = function unselectCase(){
            if( getSelectedCase() === false )
                return false;
            removeCssOfCase(getSelectedCase().$element);
            removeCaseToEditableMode(getSelectedCase().$element);
            cases[getSelectedCase().$element.data('index')].isSelected = false;
        };

        var setCssOfCase = function setCssOfClickedCase($case){
            $case.addClass('selectedCase');
            $case.addClass(params.class);

            getSelectedCase().$topCase.addClass('pointer');
            getSelectedCase().$rightCase.addClass('pointer');
            getSelectedCase().$bottomCase.addClass('pointer');
            getSelectedCase().$leftCase.addClass('pointer');
        };
