使用javascript制作3D新闻Web应用程序-https://shange-fagan.github.io/globe.news/

我在控制台中得到消息,我的html元素的位置被设置为absolute,尽管在代码中我已经显式地将其设置为unset,下面是我的代码:

<head>
      <rssapp-ticker id="tRj0yIAl7HEk9RzX"></rssapp-ticker>
      <script
        src="https://widget.rss.app/v1/ticker.js"
        type="text/javascript"

 async
  ></script>
  <rssapp-wall id="tszZCksFzEB4w9UN"></rssapp-wall>

  <style>
    body {
      margin: 0;
    }
  </style>

  <script src="//unpkg.com/three"></script>

  <script src="//unpkg.com/globe.gl"></script>
  <!--  <script src="../../dist/globe.gl.js"></script>-->
</head>

<body>
  <div id="globeViz"></div>

  <script type="module">
    var my_awesome_script;

    // Gen random data
    const N = 30;
    const gData = [...Array(N).keys()].map(() => ({
      lat: (Math.random() - 0.5) * 180,
      lng: (Math.random() - 0.5) * 360,
    }));

    import { GUI } from "./js/dat.gui.module.js";
    // GUI

    const gui = new GUI();

    const textureLoader = new THREE.TextureLoader();
    const myTexture = [
      textureLoader.load("//unpkg.com/three-globe/example/img/earth-dark.jpg"),
      textureLoader.load(
        "//unpkg.com/three-globe/example/img/earth-blue-marble.jpg"
      ),
    ];

    const parameters = {
      Theme: 0,
    };

    const updateAllMaterials = () => {
      scene.traverse((child) => {
        if (
          child instanceof Globe() &&
          child.material instanceof THREE.MeshPhongMaterial
        ) {
          child.material = myTexture[parameters.Theme];
          child.material.needsUpdate = true;
        }
      });
    };

    gui
      .add(parameters, "Theme", {
        night: 0,
        day: 1,
      })
      .onFinishChange(() => {
        updateAllMaterials();
      });

    gui.open();

    const elem = document.getElementById("globeViz");
    const globe = Globe()
      .globeImageUrl(
        "//unpkg.com/three-globe/example/img/earth-blue-marble.jpg"
      )(elem)
      //.globeMaterial([MeshPhongMaterial])
      .bumpImageUrl("//unpkg.com/three-globe/example/img/earth-topology.png")
      .backgroundImageUrl("//unpkg.com/three-globe/example/img/night-sky.png")
      .showGraticules(true)
      .showAtmosphere(true)
      .htmlElementsData(gData)
      .htmlElement(({}) => {
        var my_awesome_script = document.createElement("iframe");
        my_awesome_script.type = "iframe";
        my_awesome_script.async = true;
        my_awesome_script.setAttribute(
          "src",
          "https://rss.app/embed/v1/wall/t0OXjFMGzjEUhPqm"
        );
        //my_awesome_script.setAttribute("class", "card");
        return `
     <link rel="stylesheet" href="input.css"> <!--Copy this line of code-->
    <div>${my_awesome_script}</div>
        `;
        my_awesome_script.style.background = "none";
        my_awesome_script.style.border = "none";
    //position is clearly set to unset
        my_awesome_script.style.position = "unset";
        my_awesome_script.style.objectFit = "contain";
        my_awesome_script.style.width = 20;
        my_awesome_script.style.height = 30;
        document.getElementById("iframe").style.position = "unset";
        document.getElementsByClassName("card").style.position = "unset";
      });

    // custom globe material
    const globeMaterial = globe.globeMaterial();
    globeMaterial.bumpScale = 10;
    new THREE.TextureLoader().load(
      "//unpkg.com/three-globe/example/img/earth-water.png",
      (texture) => {
        globeMaterial.specularMap = texture;
        globeMaterial.specular = new THREE.Color("grey");
        globeMaterial.shininess = 15;
      }
    );

    setTimeout(() => {
      // wait for scene to be populated (asynchronously)
      const directionalLight = globe
        .scene()
        .children.find((obj3d) => obj3d.type === "DirectionalLight");
      directionalLight && directionalLight.position.set(1, 1, 1); // change light position to see the specularMap's effect
    });

    globe.controls().autoRotate = true;
    globe.controls().autoRotateSpeed = 0.85;

    //const animate = () => {
    //requestAnimationFrame(animate);
    //globe.rotation.y += 0.01;
    //}

    //animate();
  </script>
</body>

请让我知道我做错了什么,不确定是因为我的html元素的src有自己的样式,我没有访问权限,还是我应该使用typescript而不是javascript。
编辑:这是devtools的elements选项卡中元素及其父元素的屏幕截图,您可以看到元素包含在使用var my_element = document.createElement(element)的script标记中,必须这样做,因为我需要html元素显示在使用javascript

x 1c 2d 1x的3d地球仪上
第2次编辑:实现建议代码后的新错误屏幕截图:

第三次编辑:修复后的rss新闻小部件嵌入链接,它开始显示,但不是在我想要的方式,它显示的小部件上方的地球仪,而不是在地球仪上,因为是首选:x1c4d 1x理想情况下,小部件将悬停在地球仪上,如这些标记示例

您的错误

在没有有效参数的情况下调用Globe().htmlElement({} => html)时,错误来自globe.gl。在创建脚本标记和定义iframe的方式中存在多个错误。样式位置错误与行my_awesome_script.style.position = "unset";无关。
使用检查器,变量t显示您将iframe作为字符串("\n...<iframe ...")而不是有效的HTML元素返回,因此在元素上定义样式时,它会在第37713行产生错误。

下面对globe对象的编辑应该会给予你更好的结果。它是基于你的index6.html的。详细的解释见注解

const globe = Globe()
      .globeImageUrl(

        console.log(d)
        
        // this element should be script instead of div
        // var my_awesome_script = document.createElement("div");
        var my_awesome_script = document.createElement("script");
        my_awesome_script.type = "text/javascript";
        my_awesome_script.async = true;
        my_awesome_script.setAttribute(

        );
        
        // you don't need to add class to the script tag
        // my_awesome_script.setAttribute("class", "card");

        // Returning the iframe and my_awesome_script creates the error. 
        // Instead, you should handle the iframe string and my_awesome_script script element separately
        // return `<iframe width="900" height="1600" style="border:none, background:none, position: unset;" src="https://rss.app/embed/v1/wall/t0OXjFMGzjEUhPqm" frameborder="0"></iframe><link rel="stylesheet" href="input.css"> <!--Copy this line of code--><div class="card">${my_awesome_script}</div>`;

        // For clarity, let's put this iframe string in its own variable without the my_awesome_script
        let my_html_string = `<iframe width="900" height="1600" style="border:none, background:none, position: unset;" src="https://rss.app/embed/v1/wall/t0OXjFMGzjEUhPqm" frameborder="0"></iframe>

          <div class="card"></div>`;
        
        // create an empty div element
        let wrapper = document.createElement('div')

        // add your string here to turn it into an HTML element
        wrapper.innerHTML = my_html_string

        // append your script HTML element
        wrapper.appendChild(my_awesome_script)

        // return everything as HTML element containing both iframe and script
        return wrapper; 

        // anything below return has no effect, also no point applying style to a script tag 

        // my_awesome_script.style.background = "transparent";
        // my_awesome_script.style.objectFit = "contain";
        // my_awesome_script.style.position = "static";
