记录数组问题

数组遍历问题
var _TheArray = [{"data":["0-1","0-2","0-3"],id:"111"},{"data":["1-1"],id:"222"},{"data":["2-1","2-2"],id:"333"},{"data":["3-1","3-2"],id:"444"}];
var dataMaxLength = 0;
for(var n in _TheArray){
if(_TheArray[n].data.length > dataMaxLength ){
dataMaxLength =_TheArray[n].data.length;
}
}
console.log("dataMaxLength :"+dataMaxLength );
if(dataMaxLength > 0){
for(var j=0;j < dataMaxLength;j++){
for(var k=0;k<_TheArray.length;k++){
if(_TheArray[k].data[j] != undefined){//防止data长度层次不齐
console.log(_TheArray[k].data[j]);
}
}
} }
复习 二维数组的建立 和增加元素
var _TheArray = [{"data":["0-1","0-2","0-3"],id:"111"},{"data":["1-1"],id:"222"},{"data":["2-1","2-2"],id:"333"},{"data":["3-1","3-2"],id:"444"}];
var _TheArrayTwo = new Array();
_TheArrayTwo[0] = _TheArray;_TheArrayTwo.push(_TheArray);
_TheArrayTwo
