Unity Webgl端有时候会有这样一个需求，在Unity界面上内嵌一个网页，并且可以在界面上把这个网页关掉（不是重新打开新的标签页）
效果如下：
现在来实现这个功能：
1.在Assets文件夹下新建一个Plugins目录：
在Plugins文件夹中创建一个文件 __Internal.jslib (必须是jslib格式，并且必须在Plugins文件夹下)
__Internal.jslib内容如下：
mergeInto(LibraryManager.library, {
//开启新窗口
OpenUrlWindow:function(str)
{
OpenUrl_Window(Pointer_stringify(str)); //调用js方法
},
//关闭新窗口
CloseUrlWindow:function()
{
CloseUrl_Window();//调用js方法
},
});
2.新建一个脚本 脚本内容如下：
using System.Runtime.InteropServices;
using UnityEngine;
using UnityEngine.UI;
public class WebglOpenUrlTest : MonoBehaviour
{
public string url;
public Button Btn_NewWin;
public Button Btn_CloseWin;
[DllImport("__Internal")]
private static extern void OpenUrlWindow(string str);
[DllImport("__Internal")]
private static extern void CloseUrlWindow();
void Start()
{
Btn_NewWin.onClick.AddListener(delegate
{
OpenUrlWindow(url);
});
Btn_CloseWin.onClick.AddListener(delegate
{
CloseUrlWindow();
});
}
}
将该脚本挂载在物体对象上
打Webgl包，打包完成后，打包文件夹中会有一个index.html文件
打开文件添加以下内容：
我的index.html如下：
DOCTYPE html>
<html lang="en-us">
<head>
<meta charset="utf-8">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Unity WebGL Player | 水库3D模型title>

<script>
var container = document.querySelector("#unity-container");

function unityShowBanner(msg, type) {
function updateBannerVisibility() {
warningBanner.style.display = warningBanner.children.length ? 'block' : 'none';
}
var div = document.createElement('div');
div.innerHTML = msg;
warningBanner.appendChild(div);
if (type == 'error') div.style = 'background: red; padding: 10px;';
else {
if (type == 'warning') div.style = 'background: yellow; padding: 10px;';
setTimeout(function() {
warningBanner.removeChild(div);
updateBannerVisibility();
}, 5000);
}
updateBannerVisibility();
}
var buildUrl = "Build";
var loaderUrl = buildUrl + "/OpenUrlWebgl.loader.js";
var config = {
dataUrl: buildUrl + "/OpenUrlWebgl.data",
frameworkUrl: buildUrl + "/OpenUrlWebgl.framework.js",

};
if (/iPhone|iPad|iPod|Android/i.test(navigator.userAgent)) {
container.className = "unity-mobile";
config.devicePixelRatio = 1;
unityShowBanner('WebGL builds are not supported on mobile devices.');
} else {
canvas.style.width = "1920px";
canvas.style.height = "1080px";
}
loadingBar.style.display = "block";
var script = document.createElement("script");
script.src = loaderUrl;
script.onload = () => {
createUnityInstance(canvas, config, (progress) => {
progressBarFull.style.width = 100 * progress + "%";
}).then((unityInstance) => {

fullscreenButton.onclick = () => {

将项目用本地服务打开即可
