Question

我正在尝试单击Selenium中的链接（Python 2.7）。这是HTML代码：

<div class="buttons">
        <a href="https://twitter.com/login?redirect_after_login=%2Flogout" class="btn cancel">Cancel</a>
        <button type="submit" class="btn primary-btn js-submit">Log out</button>
      </div>

我正在尝试点击“退出”按钮。我试过了：

elem = driver.find_element_by_link_text("Log out").click()

但这似乎不起作用。

任何帮助表示赞赏！：）

“按链接文字”定位器仅适用于链接 - contact_view.getSelectionModel().selectedItemProperty().addListener(new ChangeListener() { @Override public void changed(ObservableValue obs, Object oldSelection, Object newSelection) { if (newSelection != null) { TableView.TableViewSelectionModel selectionModel = contact_view.getSelectionModel(); ObservableList selectedCells = selectionModel.getSelectedCells(); tablePosition = (TablePosition) selectedCells.get(0); row = tablePosition.getRow(); col = tablePosition.getColumn(); Object colname = tablePosition.getTableColumn().getId(); val = (String) notes.getCellData(row); String tmp=""; tmp = String.valueOf(cntac_name.getCellData(row)); frozenCol.setText(tmp); System.out.println("Hola mundo 563 "+" "+row +" "+col+" "+val+" "+colname+" "+tmp); // frozenCol.setText((java.lang.String) val); if(col == 21) { notes.setCellFactory(TextFieldTableCell.<Contact>forTableColumn()); notes.setOnEditStart(new EventHandler<CellEditEvent<Contact, String>>() { @Override public void handle(CellEditEvent<Contact, String> t) { ((Contact) t.getTableView().getItems().get(t.getTablePosition().getRow())).setNotes(t.getNewValue()); String cscode =t.getTableView().getItems().get(t.getTablePosition().getRow()).cstmr_code; String newValue =t.getNewValue(); // notes.setText((java.lang.String) newValue); System.out.println("Hola mundo 615 "+t.getNewValue()+" "+t.getTableView().getItems().get(t.getTablePosition().getRow()).cstmr_code); String ok=String.valueOf(cssEditorFld.getText()); System.out.println("Hola mundo 617 "+" "+row +" "+col+" "+val+" "+cntac_name.getCellData(row)+" "+cssEditorFld.getText()+" "+ok); // boolean r = CstmersDBConnection.UpdateSingleContact(cscode, cntac_code, colname, newValue); //setCellFactory(SetEditorTxtArea()); Stage s=new Stage(); Object p =cntac_name.getCellData(row); s.initModality(Modality.APPLICATION_MODAL); s.initStyle(StageStyle.DECORATED); s.setResizable(true); s.setTitle(String.valueOf(p)); Group root = new Group(); GridPane gridpane = new GridPane(); gridpane.setPadding(new Insets(1)); gridpane.setHgap(1); gridpane.setVgap(1); cssEditorFld.setText(String.valueOf(val)); cssEditorFld.setPrefRowCount(20); cssEditorFld.setPrefColumnCount(150); cssEditorFld.setWrapText(true); cssEditorFld.setPrefWidth(300); GridPane.setHalignment(cssEditorFld, HPos.CENTER); gridpane.add(cssEditorFld, 0, 1); HBox hbox = addHBox(); gridpane.add(hbox, 0, 2); root.getChildren().add(gridpane); s.setScene(new Scene(root)); s.show(); buttonYs.setOnAction(new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent e) { System.out.println(" Clicked Yes"); String ok=String.valueOf(cssEditorFld.getText()); n= true; s.hide(); ((Contact) t.getTableView().getItems().get(t.getTablePosition().getRow())).setNotes(cssEditorFld.getText()); System.out.println("Hola mundo 627 "+" "+row +" "+col+" "+cssEditorFld.getText()+" "+((Contact) t.getTableView().getItems().get(t.getTablePosition().getRow())).notes); } }); System.out.println("Hola mundo 631 "+" "+row +" "+col+" "+val+" "+p+" "+cntac_name.getCellData(row)+" "+cssEditorFld.getText()); buttonNo.setOnAction(new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent e) { System.out.println(" Clicked No"); n = false; s.hide(); } }); } });元素。在这里，您可以使用XPath检查按钮的文本：

作为旁注，在此代码中：

driver.find_element_by_xpath("//button[. = 'Log out']").click()

将elem = driver.find_element_by_link_text("Log out").click()的结果分配给变量没有多大意义 - 它总是click()。
