                </div>
            </div>

JS

$( document ).on( 'keydown', function ( e ) {
            if ( e.keyCode === 32 ) {
                if (video.paused == true) {
                    // Play the video
                    video.play();
                }else{
                    if(video.play == true){
                    video.pause();
                    }
                }
            }
        });

Answer 1

以下是您对javascript的更改：

＆＃13;

$(window).keypress(function(e) {
  var video = document.getElementById("vid");
  if (e.which == 32) {
    if (video.paused)
      video.play();
    else
      video.pause();
  }
});

使用x_train = tokenizer.texts_to_sequences(train_df) x_test = tokenizer.texts_to_sequences(test_df) maxlen = 43036 vocab_size = len(tokenizer.word_index) + 1 x_train = pad_sequences(x_train, padding='post', maxlen=maxlen) x_test = pad_sequences(x_test, padding='post', maxlen=maxlen) mlb_label_train = MultiLabelBinarizer() y_train = mlb_label_train.fit(label_train.values) y_train_tags = mlb_label_train.fit_transform(label_train.values) mlb_label_test = MultiLabelBinarizer() y_test = mlb_label_test.fit(label_test.values) y_test_tags = mlb_label_test.fit_transform(label_test.values) model = Sequential() model.add(Embedding(input_dim=vocab_size, output_dim=200, input_length=maxlen)) model.add(Dropout(0.3)) model.add(Conv1D(filter_length, 3, padding='valid', activation='relu')) model.add(GlobalMaxPooling1D()) model.add(Dense(200)) model.add(Activation('sigmoid'))可以停止将网页滚动到底部。

e.preventDefault()

var videoPlayer = document.getElementById('Video1')
$(window).keypress(function(e) {
  if (e.keyCode == 0 || e.keyCode == 32) {
	if (videoPlayer.paused == false) {
            videoPlayer.pause();
            videoPlayer.firstChild.nodeValue = 'Play';
        } else {
            videoPlayer.play();
            videoPlayer.firstChild.nodeValue = 'Pause';
        }
  
  }
});

Answer 4

在这里，你应该这样做。

// Press spacebar to Play/Pause.
    var body = $( 'body' );

    body.keypress( function ( e ) {
        if ( e.which == 32 ) {
            // Stop the jerk.
            e.preventDefault();

            // If video is paused.
            if ( theVideo.get(0).paused == true ) {
                theVideo.get(0).play();
            } else {
                theVideo.get(0).pause();
            }
        }
    }); // End keypress().
