html页面的单引号，双引号

html页面单引号，双引号。 如果有双引号，里面的东西就只能单引号， 要不然添加 符号 \ 在双引号开始前面添加

原来的

                                <div class="info">
                                    <h3 class="title" style="padding-bottom: 0px" id="title"></h3>
                                    <div class="desc">
                                        <p id="content">&nbsp; &nbsp; &nbsp; &nbsp;</p>

                                    </div>
 								 <div class="thumbnail">
                                    <img class="w-100" src="../assets/images/portfolio/img_01.png" alt="Blog Image">
                                </div>
								<div class="thumbnail">
                                    <img class="w-100" src="../assets/images/portfolio/img_02.jpg" alt="Blog Image">
                                </div>

                                </div>

改后的

"<div class=\"info\">"+
                            "<h3 class=\"title\" style=\"padding-bottom: 0px\" id=\"title\"></h3>"+
                            "<div class=\"desc\">"+
                                "<p id=\"content\">&nbsp; &nbsp; &nbsp; &nbsp;</p>"+
                            "</div>"+
                            "<div class=\"thumbnail\">"+
                                "<img class=\"w-100\" src=\"../assets/images/portfolio/img_01.png\" alt=\"Blog Image\">"+
                            "</div>"+
                            "<div class=\"thumbnail\">"+
                                "<img class=\"w-100\" src=\"../assets/images/portfolio/img_02.jpg\" alt=\"Blog Image\">"+
                            "</div>"+
                        "</div>"
