重构--eltriggerBeginTimen---------------------elstatus-==-0n-----------------------eleffectType-==-1n-------------------------n-------------------------eltriggerBeginTimeslice0-10n-----------------------elfireTimeslice0-10n---------------------

重构后的代码如下：

if (el.triggerBeginTime) { if (el.status === 0) { if (el.effectType === 1) { return ''; } else { return el.triggerBeginTime.slice(0, 10); } } else { return el.fireTime.slice(0, 10); } } else { return ''; }
