Question

如果我有多个具有不同ID的对象，但是单击它们时它们都调用相同的函数。有什么方法可以跟踪或找到哪个对象称为函数。

例如

org.apache.spark.sql.AnalysisException: Path does not exist: file:/User/myname/documents/data/xyz.csv;
  at org.apache.spark.sql.execution.datasources.DataSource$$anonfun$14.apply(DataSource.scala:382)
  at org.apache.spark.sql.execution.datasources.DataSource$$anonfun$14.apply(DataSource.scala:370)
  at scala.collection.TraversableLike$$anonfun$flatMap$1.apply(TraversableLike.scala:241)
  at scala.collection.TraversableLike$$anonfun$flatMap$1.apply(TraversableLike.scala:241)
  at scala.collection.immutable.List.foreach(List.scala:381)
  at scala.collection.TraversableLike$class.flatMap(TraversableLike.scala:241)
  at scala.collection.immutable.List.flatMap(List.scala:344)
  at org.apache.spark.sql.execution.datasources.DataSource.resolveRelation(DataSource.scala:370)
  at org.apache.spark.sql.DataFrameReader.load(DataFrameReader.scala:152)
  at org.apache.spark.sql.DataFrameReader.csv(DataFrameReader.scala:415)
  at org.apache.spark.sql.DataFrameReader.csv(DataFrameReader.scala:352)

如果您正在使用

Path inputFile = Paths.get("src/inware/users.txt");
Path outputFile = Paths.get("src/inware/usersT.txt");
try {
    try (BufferedReader in = Files.newBufferedReader(inputFile);
         PrintWriter out = new PrintWriter(Files.newBufferedWriter(outputFile))) {
        for (String line; (line = in.readLine()) != null; ) {
            line = line.trim();
            if (! line.isEmpty())
                out.println(line);
        }
    }
    Files.delete(inputFile);
    Files.move(inputFile, outputFile);
} catch (IOException ex) {
    Logger.getLogger(ManageStudentController.class.getName()).log(Level.SEVERE, null, ex);
}

在元素中进行更改，以便将其自身传递给函数：

onclick="test()"

然后函数接收对象作为参数。

onclick="test(this)"

Answer 2

只需执行以下操作：

function test(id) {

    document.getElementById('div').style.backgroundColor = 'red';

    var objectID = id;

    document.getElementById('textbox').innerHTML = objectID;
}

var object = {

    id = "AnObject",
    testFunction: function() {
        test(this.id);
    }

};

object.testFunction();
