Question

我是这个领域的新手，一直在尝试使用x3dom对象。我现在面临的问题是如何将x3dom对象的属性显示为弹出窗口。我已经看过x3dom网站上给出的例子，但还没有找到任何相关的例子。如果有人有一些例子可以分享，我会很高兴。提前谢谢。

Answer 1

您可以使用attributes属性（例如document.getElementById("id").attributes），这是一个显示单击任一按钮时属性表的示例：

<!DOCTYPE html>
<html lang="en">
<head>

  <meta charset="utf-8">
    <title>X3DOM</title>
    <link href="http://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/2.0.4/css/bootstrap.min.css" rel="stylesheet" />

</head>
<body class="container">


    <X3D width="100%" height="300px">
        <Scene>
            <Shape id="myShape">
                <Appearance>
                    <Material id="myMaterial" diffuseColor="0.6 0.6 0.6" specularColor="0.8 0.8 0.8" shininess="0.145" ambientIntensity="0.2" emissiveColor="0,0,0"/>
                </Appearance>
                <Sphere />
            </Shape>
        </Scene>
    </X3D>


    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
    <script src="http://x3dom.org/x3dom/release/x3dom.js"></script>
    <script>
    function displayAttributes(objectId){
        var code = '';
        var attributes = document.getElementById(objectId).attributes;
        $.each(attributes, function(index, attr) {
            code += '<tr><th>' + attr.name +'</th><td>' + attr.value + '</td></tr>';
        });
        $("#attributesTable").html(code);
    }
    </script>


    <button onclick="displayAttributes('myShape')" class="btn btn-large">Attributes of the shape</button>
    <button onclick="displayAttributes('myMaterial')" class="btn btn-large">Attributes of the material</button>

    <table id="attributesTable" class="table table-striped table-bordered" style="margin-top:50px"></table>


</body>
</html>
