背景
allWebDesktop控件是一款方便用户在线打开各类文档的OA办公控件。它设计比较轻巧，充分利用计算机程序资源打开文档，并将程序窗口嵌入到allWebDesktop控件区域内，从而实现浏览器内打开各类文档效果。
allWebPlugin中间件是一款为用户提供安全、可靠、便捷的浏览器插件服务的中间件产品，致力于将浏览器插件重新应用到所有浏览器。它不仅可以实现ActiveX控件在现代浏览器上使用，而且集成也非常方便。
alWebPlugin中间件核心优势
1、自创定位算法，实现插件与页面布局无缝衔接，极致用户体验。
2、自创插件接口调用方法，保持原汁原味的接口调用及事件响应方式，轻松实现OA系统升级改造。
3、支持同一页面或不同页面同时加载多个插件，适应各种复杂应用场景。
4、自主创新、安全可控，不受浏览器插件技术限制，支持更多浏览器（谷歌、火狐、Edge、360浏览器等）。
5、创新沙箱机制,隔离插件与浏览器运行环境，增强插件与浏览器稳定性和安全性。
6、攻克诸多技术难点，实现插件不修改、不注册也能使用，极大的降低插件开发量和维护量。
准备工作
1、下载allWebPlugin中间件产品，具体如下：
链接：百度网盘 请输入提取码
提取码：z3q0
如下图所示，下载allWebPlugin_x86_v2.0.0.24_alpha_20241028.zip安装包。
运行效果
运行效果如下图所示：
集成代码
allWebPlugin中间件集成步骤
第一步：导入js相关文件
导入jquery.min.js，allWebPlugin.Common.js，allWebPlugin.UI.js文件。
<script type="text/javascript" src="js/jquery.min.js"></script><script type="text/javascript" src="js/allWebPlugin.Common.js"></script><script type="text/javascript" src="js/allWebPlugin.UI.js"></script> 第二步：替换<object>页面元素代码
将网页中<object>元素替换成<canvas>元素。如下图所示：
<td align="left">
<!--object id="HWPenSign"name="HWPenSign"classid="clsid:E8F5278C-0C72-4561-8F7E-CCBC3E48C2E3"width="600"height="300"></object-->
<canvas id="pluginUI" width="600" height="300">
<p class="error">Sorry, It looks as though your browser does not support the canvas tag.</p>
</canvas>
</td>第三步：拷贝控件创建方法
拷贝控件创建方法CreateContainer及CreatePlugin，将其放到网页onload事件里面，方便页面加载时，创建控件对象。其中createProxyPlugin方法创建控件对象，需要传入控件的classid或者ProgID。
var allWebDesktop;var hostCnt = null;
function init(){ CreateContainer();
}function CreateContainer(){var canvas = document.getElementById('pluginUI');var license = "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"; var installPackageUrl = "http://127.0.0.1:6651/install/allwebPlugin_x86_v2.0.1.16_20240806.exe";var installPackageVersion = "2.0.0.20"; hostCnt = new PluginHostCnt();if(hostCnt.IsInstall() == false){//未安装，需要手动安装if(confirm("allWebPlugin中间件未安装或未启动,是否立即安装？")){window.open(installPackageUrl, '_blank');}}else{//已安装，检测是否需要版本更新if(hostCnt.IsNewVersion(installPackageVersion) == false){if(hostCnt.createContainer(canvas,"PluginContainer",license,false,true) == true){ //hostCnt.UI.ForceShowUI(false);//创建时隐藏插件,需要调用这句，隐藏插件CreatePlugin();}}else{//需要升级alert("检测到升级包,立即升级。");hostCnt.UpdateVersion(installPackageUrl).then(function(data){if(data.code == 0){ //检测是否安装成功var checkInstall = setInterval(function(){if(hostCnt.GetVersion() == installPackageVersion){window.location.reload();clearTimeout(checkInstall);}}, 1000);}else{window.open(installPackageUrl, '_blank');//直接下载包，手动安装}}).catch(function(strErr){window.open(installPackageUrl, '_blank');//直接下载包，手动安装});}}
}function CreatePlugin(){if(hostCnt == null)return;allWebDesktop = hostCnt.createProxyPlugin("{c8a21e7f-d127-445d-af66-cfd3c8d1b765}");
}第四步：插件接口调用
调用插件对象接口，注意：调用插件读属性与传统调用存在差异，需要在属性后面加上“()”方可获取属性值（仅适合createProxyPlugin方法创建的插件对象）。如下图所示：
function openFile(){var pluginUtilityObj = hostCnt.getPluginUtility();pluginUtilityObj.GetLocalOpenDialog("docx文件(*.docx;*.doc);;excel文件(*.xls;*.xlsx);;所有文件(*.*)").then(function(varFile){console.log(varFile);if(varFile != "")allWebDesktop.Open(varFile,"");//插件Open方法});
}function Close(){allWebDesktop.Close(0);//插件Open方法
