以下是js，当我尝试保存它时，它显示“元素的内容必须包含格式良好的字符数据或标记。”错误，请帮助我解决这个问题

    if ($('html').hasClass('csstransforms3d')) {

        var foldingList = $('.folding'),
            foldingListHeight = $('.folding').height();
            topElemOffset = foldingList.offset().top,
   **===========================================^

            // Function responsible for unfolding the list
            unfold = function(){
                setTimeout(function(){
                    if (foldingList.hasClass('folded')){
                        foldingList.removeClass('folded');
                        return;
                    }
                }, 500);
            }

        // Fold/Unfold the list
        $('.connect').on("click",function(){

    **==^

            foldingList.toggleClass('folded');
        })
        // If needed, unfold the list right away
        if (topElemOffset <= $(window).height() - foldingListHeight)
            unfold();
    **===^

        // Check whether to unfold the list when scrolling/resizing
        $(window).on("scroll resize", function(){
            var th = $(this);               
            if (th.scrollTop() + th.height() - foldingListHeight  >=  topElemOffset)
                unfold();

        })
    }

})()
</script>

Answer 1

错误信息非常清楚。

 topElemOffset = foldingList.offset().top; // ; instead of ,

 ...

 $('.connect').on("click",function(){
        foldingList.toggleClass('folded');
    }); // semicolon was mising

 ...
 //write if-statements like this
 if(expression){
     //dowork
 }

任何人都可以解决我的Javascript形成问题吗？
