I want to push elements to 2D array,
我想将元素推送到二维数组，
My code is,
我的代码是，
var results = [];
var resultstemp = [];
function bindlinks(aamt,id1) {
resultstemp=results;
imagesArray.push($("#image1").mapster("get"));
if(results.length==0)
{
results.push([id1]);
}
else
{
var ck=0;
var lng=results.length;
for (var i = 0; i < lng; i++) {
if(results[i]==id1)
{
ck=1;
results = jQuery.grep(results, function(value) {
return value != id1;
});
}
}
if(ck==0)
{
results.push(id1);
}
}
I want to push idas well as aamtto array. Here i am pushing only id to array. I am not sure about how to add aamtto second position in 2D array.
我想推动id以及aamt阵列。在这里，我只将 id 推送到数组。我不确定如何添加aamt到二维数组中的第二个位置。
Help me please,
请帮帮我，
Thank you
谢谢

Change the declaration as follows:
更改声明如下：
var results = new Array();
and change the pushas follows:
并更改push如下：
results.push([id1,aamt]);
Hope it would help

The logic behind the method to push two separate values in the same array evenly is something like this:
在同一数组中均匀推送两个单独值的方法背后的逻辑是这样的：
var array = [];
function push(id1, aamt) {
for (var i= 0; i < 10; i++) {
if (i%2 == 0) {
array.push(id1);
}
else {
array.push(aamt);
}
}
}
push(10, 12);
console.log(array); // 10, 12, 10, 12.....
Take note i abstracted the code quite a bit, because for me was not too obvious what the code should have to do, but the principle is simple: use the modulo (%) operator to test if the value is odd or even. If odd add the first value if even add the second value.
注意我对代码进行了相当多的抽象，因为对我来说代码应该做什么不是很明显，但原理很简单：使用模（%）运算符来测试值是奇数还是偶数。如果奇数添加第一个值，如果偶数添加第二个值。
Hope it helps.
希望能帮助到你。
