您提供的嵌入代码仅在包含在HTML文件中时才有效。动态添加时不起作用。例如,如果你在Web浏览器中打开一个空的HTML文件,然后运行:
document.body.innerHTML += "<div id='cont_5caab8f298a3d34d53973f2d8906d1f7'><script type='text/javascript' async src='https://www.tiempo.com/wid_loader/5caab8f298a3d34d53973f2d8906d1f7'></script></div>";

,你会看到,外部内容不会被加载。这是因为以这种方式添加时,脚本will not会自动执行。
但是,您不需要执行此外部脚本。它所做的只是创建并插入一个iframe,并设置一些属性和样式。如果我们看一下script的源代码,我们可以将它翻译成GWT等价物。
嵌入JS脚本:
conte = document.getElementById("cont_5caab8f298a3d34d53973f2d8906d1f7");
if (conte) {
conte.style.cssText = "width: 176px; color: #868686; background-color:#FFFFFF; border:1px solid #D6D6D6; margin: 0 auto; font-family: Roboto;";
elem = document.createElement("iframe");
elem.style.cssText = "width:176px; color:#868686; height:200px;";
elem.id = "5caab8f298a3d34d53973f2d8906d1f7";
elem.src = "https://www.tiempo.com/getwid/5caab8f298a3d34d53973f2d8906d1f7";
elem.frameBorder = 0;
elem.allowTransparency = true;
elem.scrolling = "no";
elem.name = "flipe";
conte.appendChild(elem);
}
GWT等价的:
public class Hello implements EntryPoint {
public void onModuleLoad() {
Panel root = RootPanel.get("main"); // replace with your Panel
//This doesn't work:
//HTML embed = new HTML("<div id='cont_5caab8f298a3d34d53973f2d8906d1f7'><script type='text/javascript' async src='https://www.tiempo.com/wid_loader/5caab8f298a3d34d53973f2d8906d1f7'></script></div>");
//This does:
Frame embed = new Frame("https://www.tiempo.com/getwid/5caab8f298a3d34d53973f2d8906d1f7");
embed.setStyleName(""); // remove GWT styling. You could add your own CSS class here.
embed.getElement().setAttribute("style", "width:176px; color:#868686; height:200px;");
embed.getElement().setAttribute("frameborder", "0");
embed.getElement().setAttribute("scrolling", "no");
root.add(embed);
}
}
