我正在尝试用javaScript制作视频播放器用于学校项目,但我的静音按钮出现问题。
I am trying to make a video player in javaScript for a school project but I am having trouble with my mute button.
我希望按钮在点击时静音视频,如果再次按下按钮则取消静音。到目前为止,我只能将视频静音并保持静音。
I want the button to mute the video when clicked and unmute if the button is pressed again. So far I have only been able to mute the video and keep it muted.
这是我当前的静音按钮。
Here is my current mute button.
var button = document.getElementById('mute');
button.onclick = function (){
video.muted = true;
};
我尝试了if else语句,但没有成功
I tried an if else statement but it was unsuccessful
var button = document.getElementById('mute');
button.onclick = function (){
if (video.muted = false) {
video.muted = true;
}
else {
video.muted = false;
}
};
感谢您的帮助。
推荐答案
if (video.muted = false) {
video.muted = true;
}
这应该是
if (video.muted === false) {
video.muted = true;
}
否则else语句永远不会运行,因为你正在设置video.muted每次在if语句中都为false。
Or else the else statement will never run, since you are setting video.muted to false every time in the if statement itself.
