Question

从sparql开始，希望在我的＆＃34; abstract＆＃34;中执行显示的SPARQL查询。 div，我遇到了一个我无法消除的错误。所以我发布我的消息以获得意见（和解决方案？）最终显示我的请求的结果。

这是我的错误：

jquery.min.js：4 GET http://dbpedia.org/sparql?query=PREFIX%20dbpedia2%3A%20%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2F%3E%20PREFIX%20Abs%3A%20%3Chttp%3A%2F%2Fdbpedia.org%2Fontology%2F%3E%20SELECT%20%3Fabstract%20WHERE%20%7B%20%3Fs%20dbpedia2%3ACivil_engineeringe%22%40en%3B%20Abs%3Aabstract%20%3Fabstract%20%7D&format=json&callback=jQuery111006239110193011803_1512251513037&_=1512251513038 净:: ERR_ABORTED

这是我的剧本：

}

执行sparql查询到JS脚本时出错？
