【问题描述】：

我正在尝试将此Simple Marquee plugin 用作新闻行情。我已经完成了所有文档。但是，我仍然收到一条错误消息，“Uncaught ReferenceError: createMarquee is not defined”。为什么我会收到此错误。如何解决？

$(function (){
  createMarquee();
});

.container {
  width: 100%;
  background: #4FC2E5;
  float: left;
  display: inline-block;
  overflow: hidden;
  box-sizing: border-box;
  height: 45px;
  position: relative;
  cursor: pointer;
}

.marquee-sibling {
  padding: 0;
  background: #3BB0D6;
  width: 20%;
  height: 45px;
  line-height: 42px;
  font-size: 12px;
  font-weight: normal;
  color: #ffffff;
  text-align: center;
  float: left;
  left: 0;
  z-index: 2000;
}

.marquee,
*[class^="marquee"] {
  display: inline-block;
  white-space: nowrap;
  position: absolute;
}

.marquee { margin-left: 25%; }

.marquee-content-items {
  display: inline-block;
  padding: 5px;
  margin: 0;
  height: 45px;
  position: relative;
}

.marquee-content-items li {
  display: inline-block;
  line-height: 35px;
  color: #fff;
}

.marquee-content-items li:after {
  content: "|";
  margin: 0 1em;
}

<div class="container">
  <div class="marquee-sibling"> Breaking News </div>
  <div class="marquee">
    <ul class="marquee-content-items">
      <li>Item 1</li>
      <li>Item 2</li>
      <li>Item 3</li>
      <li>Item 4</li>
      <li>Item 5</li>
    </ul>
  </div>
</div>

【解决方案1】：

您从 github 使用的版本与您链接的演示中的版本不同。

现在你需要这样调用插件：

$('.simple-marquee-container').SimpleMarquee();

请注意，此插件所需的 HTML 和 CSS 也已更改。

$(function (){
  $('.simple-marquee-container').SimpleMarquee();
});

.simple-marquee-container *{
	-webkit-box-sizing:border-box;
	-moz-box-sizing:border-box;
	-o-box-sizing:border-box;
	box-sizing:border-box;
	font-family:Arial, "Helvetica Neue", Helvetica, sans-serif;
}
.simple-marquee-container {
	width: 100%;
	background: grey;
	float: left;
	display: inline-block;
	overflow: hidden;
	box-sizing: border-box;
	height: 45px;
	position: relative;
	cursor: pointer;
}

.simple-marquee-container .marquee-sibling {
	padding: 0;
	background: rgb(61, 61, 61);
	width: 20%;
	height: 45px;
	line-height: 42px;
	font-size: 12px;
	font-weight: normal;
	color: #ffffff;
	text-align: center;
	float: left;
	left: 0;
	z-index: 2000;
}

.simple-marquee-container .marquee, .simple-marquee-container *[class^="marquee"] {
	display: inline-block;
	white-space: nowrap;
	position:absolute;
}

.simple-marquee-container .marquee{
  margin-left: 25%;
}

.simple-marquee-container .marquee-content-items{
  display: inline-block;
  padding: 5px;
  margin: 0;
  height: 45px;
  position: relative;
}

.simple-marquee-container .marquee-content-items li{
  display: inline-block;
  line-height: 35px;
  color: #fff;
}

.simple-marquee-container .marquee-content-items li:after{
	content: "|";
	margin: 0 1em;
}

<div class="simple-marquee-container">
	<div class="marquee-sibling">
		I am here to iritate you
	</div>
	<div class="marquee">
		<ul class="marquee-content-items">
			<li>Item 1</li>
			<li>Item 2</li>
			<li>Item 3</li>
			<li>Item 4</li>
			<li>Item 5</li>
		</ul>
	</div>
</div>
