开关(switch)状态的缓存

给Javascript增加一个class

function getCache() {var $link_cache &＃61; document.querySelector("#link-cache .mui-switch");var cache_status &＃61; plus.storage.getItem("cache_status");if (cache_status &＃61;&＃61; &＃39;1&＃39;) {$link_cache.className &＃43;&＃61; "mui-active";}else if (cache_status &＃61;&＃61; &＃39;0&＃39;) {$link_cache.className &＃61; $link_cache.className.replace(&＃39;mui-active&＃39;, &＃39;&＃39;);}
}

把开关的状态记录到缓存中

document.getElementById("link-flow").addEventListener("toggle", function(event) {var isActive &＃61; event.detail.isActive;if(isActive) {plus.storage.setItem(&＃39;flow_status&＃39;, &＃39;1&＃39;);plus.nativeUI.toast(&＃39;开启流量播放!&＃39;);} else {plus.storage.setItem(&＃39;flow_status&＃39;, &＃39;0&＃39;);plus.nativeUI.toast(&＃39;关闭流量播放!&＃39;);}
});

把开关状态取出来并做判断

function getFlow() {var $link_flow &＃61; document.querySelector("#link-flow .mui-switch");var flow_status &＃61; plus.storage.getItem("flow_status");if (flow_status &＃61;&＃61; &＃39;1&＃39;) {$link_flow.className &＃43;&＃61; "mui-active";}else if (flow_status &＃61;&＃61; &＃39;0&＃39;) {$link_flow.className &＃61; $link_flow.className.replace(&＃39;mui-active&＃39;, &＃39;&＃39;);}
}
