JavaScript 将数组连接到新数组中

Question

如何加入数组并创建新数组？

var page_list = [ 'dkey', 'dvalue' ];
var json = '{"key1":"value1","key2":"value2","key3":"value3"}';
var jp = JSON.parse(json);

for( var index in jp ) {
   var obj = jp[index]; 
   //page_list.concat( ['test1','value2'] );
}

//expecting output
[ [ 'dkey', 'dvalue' ], [ 'key1', 'value1'], ['key2','value2'], ['key3','value3'] ]

有人可以给我一个解决方案，如何实现预期的输出吗？

Answer 1

var page_list = [ 'dkey', 'dvalue' ];
var arr = []; //Create new array
arr.push(page_list); //Push page_list

var json = '{"key1":"value1","key2":"value2","key3":"value3"}';
var jp = JSON.parse(json);
for( var key in jp ) {
   arr.push([key, jp[key]]); //Push key, value 
}

document.write(JSON.stringify(arr))
//outputs
//[["dkey","dvalue"],["key1","value1"],["key2","value2"],["key3","value3"]]
