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); 
}
