区分非常相似的按钮点击

Question

我有3个链接按钮具有相同的文本和类buy-input-text buy-input-general。它们都触发相同的模态对话框。我想自定义模态对话框，基于哪个按钮被单击。例如，更改h3元素。做这件事的首选方法是什么?

jQuery(document).ready(function($){
$(".showModalView").click(function(){
	$("#buy-wrapper").show();
console.log("showModalView");
});
$("#buy-wrapper").click(function(e){
	if ($(e.target).closest("#buy-box").length === 0)
		$("#buy-wrapper").hide();
console.log("closeModalView");
});
});

.buy-input-general {
  outline: none;
}
#buy-wrapper {
  display:none;
  position:absolute;
  top:25vh;
  right:0;
  bottom:0;
  left:0;
}
#buy-box {
  width: 345px;
  height: 470px;
  background-color: #fff;
  margin: 0 auto;
  -webkit-border-radius: 4px;
  -o-border-radius: 4px;
  -moz-border-radius: 4px;
  border-radius: 3px;
  border: thin solid #ededed;
}
#top_header {
  width: 100%;
  margin: 0;
  padding-top: 45px;
}
#top_header > h3 {

以下是一些输入

• 使用CSS，如果我们像下面这样构建标记(这是您自己的精简版本)

有利有弊——动态vs静态——等等。自可以理解，您正在寻找动态解决方案(并使用jQuery)，我们可以做同样的事情(参见下一个代码片段)

.button > a {
  display: block;
}
#buy-wrapper > div {
  display: none;
}
#buy-box1:target,
#buy-box2:target,
#buy-box3:target {
  display: block;
}
.dialog-box {
  position: absolute;
  top: 40px;
  left: 30%;
  padding: 10px;
  border: 2px solid red;
  z-index: 1000px;
  background-color: #DDD;
  opacity: 0.5;
}

<div>
  <div class="header">THIS IS HEADER</div>
  <p>paragraph 1</p>
  <p>paragraph 2</p>
  <div class="button">
    <a class="showModalView" href="#buy-box1">CLICK ME 1</a>
    <a class="showModalView" href="#buy-box2">CLICK ME 2 </a>
    <a class="showModalView" href="#buy-box3">CLICK ME 3</a>
  </div>
  <br />
  <div class="FOOTER">THIS IS FOOTER</div>
</div>
<hr>
<!-- Custom dialog -->
<div id="buy-wrapper">
  <div id="buy-box1" class="dialog-box">I am buying from box 1</div>
  <div id="buy-box2" class="dialog-box">I am buying from box 2</div>
  <div id="buy-box3" class="dialog-box">I am buying from box 3</div>
</div>

• 使用jQuery UI

$(document).ready(function() {
  // Initialize the `dialog` object.
  var dialogBox = $('#dialog-box').dialog({
    autoOpen: false,
    buttons: {
      "Ok": function() {
        $(this).dialog("close");
      }
    }
  });
  // Attach `click` event handler to the family - showModalView
  $(".showModalView").click(function(eventData) {
    // Get the event target
    var targetElement = eventData.target;
    // Example: To set the "item" to buy
    var item = $(targetElement).attr("data-item");
    $("#dialog-box").find("h2").html("Buy " + item);
    // Open up the "dialog box"
    $("#dialog-box").dialog("open");
  });
});

.button > a {
  display: block;
}
#buy-wrapper > div {
  display: none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.12.1/jquery-ui.js"></script>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.12.1/jquery-ui.css" />
<div>
  <div class="header">THIS IS HEADER</div>
  <p>paragraph 1</p>
  <p>paragraph 2</p>
  <div class="button">
    <a class="showModalView" href="#" data-item="Orange">CLICK ME 1</a>
    <a class="showModalView" href="#" data-item="Apple">CLICK ME 2 </a>
    <a class="showModalView" href="#" data-item="Melon">CLICK ME 3</a>
  </div>
  <br />
  <div class="FOOTER">THIS IS FOOTER</div>
</div>
<hr>
<!-- Custom dialog -->
<div id="buy-wrapper">
  <div id="dialog-box" title="Are we okay with order?">
    <h2></h2>
    <div>
      <span>First name:</span>
      <input type="text" placeholder="Enter First name" />
    </div>
    <div>
      <span>Last name:</span>
      <input type="text" placeholder="Enter Last name" />
    </div>
  </div>

Answer 2

如果它是一个HTML5项目，那么你可以使用data-* attributes
