Viewer集成
ActiveReportsJS是一款纯前端的报表控件，不仅能够在前端框架Vue、Angular、React中间接集成应用，还能够在纯 JavaScript 利用。
上面就一起来创立让ActiveReportsJS在纯JavaScript 利用
1、应用任意工具创立 HTML页面。 您可在任何文本编辑器中创立 HTML页面。 输出以下代码：
<!DOCTYPE html>
<html lang=”en”>
<head>
<meta charset="utf-8" />
<title>ARJS Report Viewer</title>
<meta name="description" content="ARJS Report viewer" />
<meta name="author" content="GrapeCity" />
</head>
<body></body>
</html>
2、装置 ActivereportsJS
可间接从 CDN 和 NPM 援用 ActiveReportJS ，最简略的办法可间接援用 CDN 链接 head。
(在理论我的项目中，都是把JS和CSS文件都间接内置在我的项目中)
`<link
rel=”stylesheet”
href=”https://cdn.grapecity.com/activereportsjs/2.latest/styles/ar-js-ui.css”
type=”text/css”
/>
<link
rel=”stylesheet”
href=”https://cdn.grapecity.com/activereportsjs/2.latest/styles/ar-js-viewer.css”
type=”text/css”
/>
<script src=”https://cdn.grapecity.com/activereportsjs/2.latest/dist/ar-js-core.js”></script>
<script src=”https://cdn.grapecity.com/activereportsjs/2.latest/dist/ar-js-viewer.js”></script>
<script src=”https://cdn.grapecity.com/activereportsjs/2.latest/dist/ar-js-pdf.js”></script>
<script src=”https://cdn.grapecity.com/activereportsjs/2.latest/dist/ar-js-xlsx.js”></script>
<script src=”https://cdn.grapecity.com/activereportsjs/2.latest/dist/ar-js-html.js”></script>`
3、增加报表 Viewer 宿主元素
body 标签中增加 div 元素<div id=“viewer-host”></div>
4、初始化 报表Viewer组件
ActiveReportsJS 应用 JSON格局和rdlx-json扩大用于报表模板文件。在应用程序的根文件夹中，创立名为report.rdlx-json的新文件，并在该文件中插入以下JSON内容
增加脚本代码：
`{
“Name”: “Report”,
“Body”: {
"ReportItems": [
{
"Type": "textbox",
"Name": "TextBox1",
"Value": "Hello, ActiveReportsJS Viewer",
"Style": {
"FontSize": "18pt"
},
"Width": "8.5in",
"Height": "0.5in"
}
]
}
}`
5、初始化 报表Viewer组件
将以下脚本增加到body标签中的viewer-host元素之后，以便该脚本在出现该元素之后运行。此代码初始化报表 Viewer实例，并在页面中加载报表文件。`<script>
`var viewer = new` `ActiveReports.Viewer(“#viewer-host”`);
`viewer.open("report.rdlx-json");`
</script>
6、整个Html实现代码
`<!DOCTYPE html>
<html lang=”en”>
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<title>ActiveReportsJS sample</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<script src="/dist/ie-polyfills.js"></script>
<script src="/dist/ar-js-core.js"></script>
<script src="/dist/ar-js-designer.js"></script>
<script src="/dist/ar-js-viewer.js"></script>
<script src="/dist/ar-js-pdf.js"></script>
<script src="/dist/designer/zh-locale.js"></script>

<link rel="stylesheet"

<style>
#viewer-host {
margin: 0 auto;
width: 100%;
height: 100vh;
}
</style>
</head>
<body>
<div id="viewer-host"></div>
<script>
const viewer = new ActiveReports.Viewer("#viewer-host", { language: "zh" });
viewer.open('reports/MonthSurvey.rdlx-json');
</script>
</body>
</html>`
