执行:
composer network ping -n calma-network -p hlfv1 -i admin -s adminpw
我收到以下错误:
Error: Error trying to ping. Error: Composer runtime (0.8.0) is not compatible with client (0.11.0)
Command failed
版本看起来一样:
composer -v
composer-cli v0.11.0
composer-admin v0.11.0
composer-client v0.11.0
composer-common v0.11.0
composer-runtime-hlf v0.11.0

我只想使用accion()javaScript函数在html上的SVG中添加一个新的文本节点:
<!DOCTYPE>
<html>
<body>
<head>
<script type="text/javascript">
function accion(){
var SVGDocument = document.getElementById("idSVG");
var text2 = SVGDocument.createTextNode("text");
SVGDocument.appendChild(text2);
}
</script>
</head>
<input type="button" onclick="accion()" value="GO!!"/>
<svg id="idSVG">
<text id="texto" x="50" y="35" font-size="14">PRUEBA</text>
</svg>
</body>
</html>
但是SVGDocument.createTextNode("text");返回一个错误:Object does not support this property or method.我认为问题是我无法正确引用idSVG元素.我正在使用IE9.

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<style>
iframe {
display: block; /* iframes are inline by default */
background: #000;
border: none; /* Reset default border */
height: 90vh; /* Viewport-relative units */
width: 90vw;
}
</style>
</head>
<body>
