             </div> 
             <div class='col-xs-3'> 
             Year 
              <input type='text' class='form-control' placeholder='year' name='from_year' required pattern='[0-9]{4,4}'>

           </div> 
            <div class='cl'></div>" 
    }); 

    }); 

    $("#item").on("click",".delete", function(){ 
    $(this).closest(".form-group").remove(); 
    });

在每行的末尾添加blackslash \。倍數行字符串不能沒有它在JS

編輯解析：與例如

$('#item').append("<div class='form-group'><label class='col-sm-4 '>Period</label><div class='col-sm-8'><div class='checkbox'><label><input type='checkbox' value='YES' name='currently_attending'>I`m currently attending this course</label></div><div class='row'><div class='col-xs-3'> Month<select class='span2 form-control' required name='from_month'><option value=''>Month</option><option value='Jan'>Jan</option> \ 
             <option value='Feb'>Feb</option> \ 
             <option value='March'>March</option> \ 
             <option value='April'>April</option> \ 
             <option value='May'>May</option>");
