我有一个按钮可以将我页面中的所有声音静音,而我还有其他可以取消静音的按钮。
$(document).ready(function(){
/*** Mute all ***/
$('#mute_all').on('click',function(){
/*** Mute all video and audio on page ***/
$('body video, body audio').each(function(){
/*** Do it here globally ***/
$(this).prop('muted', true);
});
});
/*** UnMute all ***/
$('#unmute_all').on('click',function(){
/*** Un Mute all video and audio on page ***/
$('body video, body audio').each(function(){
/*** Do it here globally ***/
$(this).prop('muted', false);
});
});
});
问题是当我刷新页面时,更改不会持续存在。我怎样才能使用LocalStorage?
谢谢!

每次用户点击静音/取消静音按钮时,请使用localStorage
将其选择保存在localStorage.setItem("name", "value")
变量中。您只能保存字符串值。
现在,在每次加载页面时,您应首先使用localStorage
检查该变量在用户localStorage.getItem("name")
中是否具有特定值,并相应地配置。

$(document).ready(function(){
// first check localStorage if any previous choice is stored
var muted = localStorage.getItem("muted");
if( muted === "true" ){
muteAll();
}
/*** Mute all ***/
$('#mute_all').on('click',function(){
muteAll();
});
/*** UnMute all ***/
$('#unmute_all').on('click',function(){
/*** Un Mute all video and audio on page ***/
$('body video, body audio').each(function(){
/*** Do it here globally ***/
$(this).prop('muted', false);
});
// save user's current choice in localStorage
localStorage.setItem("muted", "false");
});
});
function muteAll(){
/*** Mute all video and audio on page ***/
$('body video, body audio').each(function(){
/*** Do it here globally ***/
$(this).prop('muted', true);
});
// save user's current choice in localStorage
localStorage.setItem("muted", "true");
}//muteAll()

单击MuteAll可以将静音状态存储在本地存储中。并在文档就绪函数中检查其初始值。
$(document).ready(function(){
function muteAll(){
$('body video, body audio').each(function(){
$(this).prop('muted', true);
});
window.localStorage.setItem('muted','true');
}
function unmuteAll(){
$('body video, body audio').each(function(){
$(this).prop('muted', false);
});
window.localStorage.setItem('muted','false');
}
$('#mute_all').on('click',mute_all);
$('#unmute_all').on('click',unmute_all);
var status=window.localStorage.getItem('muted')
if(status && status=='true'){
mute_all();
}else{
unmute_all(); //if required
}
});

1)像这样设置项目
$('#mute_all').on('click',function(){
$('body video, body audio').each(function(){
/*** Do it here globally ***/
$(this).prop('muted', true);
});
localStorage.setItem("muted", "true")
});
2)获取此项目
localStorage.getItem("muted")
3)在文档就绪函数内检查本地存储并使用单击()
单击元素 $(document).ready(function(){
var muted = localStorage.getItem("muted");
if( muted === "true" ){
$('#mute_all').click();
}
});
