Add array to array in javascript?

Question

How do I add an array to array with variables & functions?

var ranges = new Array();
fulldate='2012/06/11:2012年10月23日|2012年03月11日:2012年05月23日'.split('|');
for(var i=0; i<fulldate.length; i++) {
 adate=fulldate[i].toString().split(':');
 startdate=adate[0].toString().split('/');
 enddate=adate[1].toString().split('/');
 //***This area****************************
 ranges.push = ({ start: new Date(startdate[0],startdate[1]-1,startdate[2]), end: new Date(enddate[0],enddate[1]-1,enddate[2]) });
 //***This area****************************
}

Answer 1

push is a method, you have to use it like this:

ranges.push({ start: new Date(startdate[0],startdate[1]-1,startdate[2]), end: new Date(enddate[0],enddate[1]-1,enddate[2]) });

Answer 2

To be persnickety, you aren't really trying to add an array to another. For that you can just use array.concat():

var cArray = aArray.concat(bArray).

It looks like you want to transform one array into another. You could use array.map():

var fulldate='2012/06/11:2012年10月23日|2012年03月11日:2012年05月23日'.split('|');
var ranges = fulldate.map(function(x) {
 var adate=x.toString().split(':');
 var startdate=adate[0].toString().split('/');
 var enddate=adate[1].toString().split('/');
 return { 
 start: new Date(startdate[0],startdate[1]-1,startdate[2]),
 end: new Date(enddate[0],enddate[1]-1,enddate[2])
 };
});
