JavaScript中将数组进行合并的基本方法讲解

这里简单地讲两种方法：
第一种  

var mergeTo = [4,5,6], mergeFrom = [7,8,9]; mergeTo = mergeTo.concat(mergeFrom); mergeTo; // is: [4, 5, 6, 7, 8, 9]

or  

var a = [1,2], b = [3,4], c = a.concat(b);

第二种 

var mergeTo = [4,5,6], var mergeFrom = [7,8,9]; Array.prototype.push.apply(mergeTo, mergeFrom); mergeTo; // is: [4, 5, 6, 7, 8, 9]

合并多个数组merge array：

// 特殊处理业务-必须启用 var _SPECIAL_MUST_ENABLE_LIST = ['intime']; if(termNo != null && termNo.indexOf("9966") == 0){ var newMustEnableList = ['mobile','psp','jtk','credit','train','bank','alipay','lottery','movie','littleTransfer', 'trafficFines','concert','mall','airplane','hotel','recycle']; _SPECIAL_MUST_ENABLE_LIST = _SPECIAL_MUST_ENABLE_LIST.concat(newMustEnableList); }
