The basic method for merging arrays in JavaScript is described.

The basic method for merging arrays in JavaScript is described.

Here are two simple methods:
First

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);  

Second

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

Merge multiple arrays merge array:

// Special processing service-you must enable var _ SPECIAL_MUST_ENABLE_LIST = ['intime']; if (termNo! = Null & termNo. indexOf ("9966") = 0) {var newMustEnableList = ['mobile', 'psp ', 'jtk', 'credentials', 'train', 'bank ', 'alipay', 'lottery', 'movi', 'littletransfer', 'trafficfines', 'certificate', 'mall', 'airplane ', 'Hotel ', 'recycle']; _ SPECIAL_MUST_ENABLE_LIST = _ SPECIAL_MUST_ENABLE_LIST.concat (newMustEnableList );}
