Question

我为按钮写了一个监听器，如下所示

$(document).on("click", ".btnclick", function() {

var htmlString = $("div#"+id_attr_val+".Topping-details").eq(0).html(); 

console.log(htmlString);

});

以上htmlString的结果是

<h6 class="tdHeading">Regular, 50 Ml 1</h6>
<i id="topping-close"></i><img src="images/arrow-topping.png">
<section class="secclass"><a href="#">Honey with Chocolate Sauce  10 ML</a></section>
<section class="secclass"><a href="#">Honey with Carmel  10 ML</a></section>

<h6 class="tdHeading">Regular, 50 Ml 2</h6>
<i id="topping-close"></i><img src="images/arrow-topping.png">
<section class="secclass"><a href="#">Honey with Chocolate Sauce  10 ML</a></section>
<section class="secclass"><a href="#">Honey with Carmel  10 ML</a></section>

<h6 class="tdHeading">Regular, 50 Ml 3</h6>
<i id="topping-close"></i><img src="images/arrow-topping.png">
<section class="secclass"><a href="#">Honey with Chocolate Sauce  10 ML</a></section>
<section class="secclass"><a href="#">Honey with Carmel  10 ML</a></section>

现在我得到了上面提到的三行数据

我的要求是，点击一个按钮，我需要再添加一行（增加h6下的数字）所以它看起来像这样，并将其附加到现有的htmlString

<h6 class="tdHeading">Regular, 50 Ml 4</h6>
<i id="topping-close"></i><img src="images/arrow-topping.png">
<section class="secclass"><a href="#">Honey with Chocolate Sauce  10 ML</a></section>
<section class="secclass"><a href="#">Honey with Carmel  10 ML</a></section>

我能够以这种方式获取最后一个h6的计数，但无法继续如何将这个新内容添加回现有的htmlString

var n = $("div#"+id_attr_val+".Topping-details h6").length ;

<h6 class="tdHeading">Regular, 50 Ml 4</h6>
<i id="topping-close"></i><img src="images/arrow-topping.png">
<section class="secclass"><a href="#">Honey with Chocolate Sauce  10 ML</a></section>
<section class="secclass"><a href="#">Honey with Carmel  10 ML</a></section>

有人可以帮忙吗？

Answer 1

Div append应该这样做。

var n = $("div#"+id_attr_val+".Topping-details h6").length ;
var text1 = $('.secclass a')[0].text;
var text2 = $('.secclass a')[1].text;
$("div#"+id_attr_val+".Topping-details h6").parent().append('<h6 class="tdHeading">Regular, 50 Ml '+n+'</h6>    <i id="topping-close"></i><img src="images/arrow-topping.png">    <section class="secclass"><a href="#">+text1 +</a></section>    <section class="secclass"><a href="#">+text2 +</a></section>')
