在 Bootstrap 中传递值

Question

下面是bootstrap显示曲目列表的代码。单击第一个代码中的标签后，它会转到#tuneIDModal，该代码也在下面提到。我想将值从超链接标签（data-myvalue）传递到#tuneIDModal（用 291033 替换值）。这两个代码都在同一页上。谁能帮我实现一下。

<div class="item">
 <div class="htt-wrap" data-url="downloadfile.jsp?filename=<%=rs1.getString("tnumber")%>.mp3">
  <img src="assets/img/desktop_top_tune_01.png" alt="01" />
   <div class="item-desc">
     <div class="item-desc-top">
     <h4><%=rs1.getString("data1")%></h4>
 <h6><%=rs1.getString("data2")%></h6>
 <span>Tune ID: <%=rs1.getString("tnumber")%></span>

Answer 1

您可以编写点击事件，这样每当您的 .db-modal 被点击时获取 attr 的值，并使用 .text("yourvalue").

在模态内的 span 标签内添加该值

演示代码 :

//on click of button
$(document).on("click", ".db-modal", function() {
//replcae value inside modal span
  $("#tid_modal").text("TID : " + $(this).attr("data-myvalue"))
})
