js中如果遇到低版本安卓设备调用setTimeout不生效解决办法
工作中会遇到低版本安卓设备调用setTimeout不生效,既不会报错,里面的函数也不会执行,这里po一个解决办法,如果不执行则执行安卓自己封装的原生的setTimeout方法:sdk.setTimeout。
注明:此方法为我们老大所写,放在这里惠存一下。
基本方案
/*******/ (function(window){ Promise.race([ new Promise((resolve)=>{ window.setTimeout(()=>{ resolve(window.setTimeout) },0) }), new Promise((resolve)=>{ sdk.setTimeout(()=>{ resolve(sdk.setTimeout.bind(sdk)) },100) }) ]).then((fn)=>{ window.setTimeout = fn }) })(window) window.setTimeout(()=>{ cosole.log('hello world') },1000) 进阶方案 /*******/ (function(window){ const st = window.setTimeout.bind(window) let callList = [] window.setTimeout = function(cb, duration){ callList.push(cb) return st(cb, duration) } Promise.race([ new Promise((resolve)=>{ window.setTimeout(()=>{ resolve(()=>{ return st }) },0) }), new Promise((resolve)=>{ sdk.setTimeout(()=>{ resolve(()=>{ callList.forEach(fn=>{ sdk.setTimeout(fn, duration) }) window.clearTimeout = sdk.clearTimeout.bind(sdk) return sdk.setTimeout.bind(sdk) }) },100) }) ]).then((fn)=>{ window.setTimeout = fn() }) })(window)
