Question

目的：

在javascript / jquery中创建二维数组
将数据推送到其中
遍历每个键，值对
循环调用函数

代码：

    var IDs = [];
    /* Find Input elements and push its ID & Value into an array */
    $('#divDynamicFields').find("input").each(function () { 
       IDs.push(this.id, $(this).val()); 
   }); 
    console.log(IDs); /* Now it prints string seprated by ',' */

   /* Loop Through Each element in 2D array */
   $.each(IDs, function(key, value) { 
     $.each(key, function(innerKey, innerValue){
        CallFunction(id,val); 
        /* Will This Work ? */
      }
   }

Answer 1

整个想法是推送数组而不是两个元素，而是一个数组，它由两个元素组成：

JSFiddle

var IDs = [];
$('#divDynamicFields input').each(function()
{ 
    IDs.push([this.id, $(this).val()]); 
});

for (var i = 0; i < IDs.length; i++)
{
    CallFunction(IDs[i][0], IDs[i][1]);
}

function CallFunction(id, value)
{
    console.log("ID: " + id + ", value: " + value);
}

Answer 2

使用对象插入

var IDs = {};
$('#divDynamicFields').find("input").each(function () {     
   IDs[this.id]= $(this).val(); 
});

同样循环

$.each(IDs , function (index, value) {
    alert( index + ' : ' + value );
});

Answer 3

你有几个问题..

第一个是你必须将输入添加为数组

       IDs.push([this.id, $(this).val()]);

第二个是你要调用你刚刚加在一起的id，你不想做双循环。

$.each(IDs, function(key, value) { 
      CallFunction(value[0],value[1]);
});

这是一个例子：

var IDs = [];
/* Find Input elements and push its ID & Value into an array */
$('#divDynamicFields').find("input").each(function () { 
   IDs.push([this.id, $(this).val()]); 
 }); 
console.log(IDs); /* Now it prints string seprated by ',' */

 /* Loop Through Each element in 2D array */
$.each(IDs, function(key, value) { 
       CallFunction(value[0],value[1]);
});

function CallFunction(id,val) {
   console.log(id+","+val);
}

Answer 4

您的推送语法和迭代错误。你应该做点什么：

var IDs = [];

IDs.push([1, 2]);
IDs.push([2, 3]);

/* Loop Through Each element in 2D array */
$.each(IDs, function(key, value) {
  alert(value);
});

Answer 5

创建二维数组

MultiArray = new Array(5)

MultiArray [0] = new Array(2)

MultiArray [0][0] = "Tom"

MultiArray [0][1] = "scientist"

MultiArray [1] = new Array(2)

MultiArray [1][0] = "Beryl"

MultiArray [1][1] = "engineer"

Answer 6

您可以尝试使用

在jquery中创建一个维数组

var IDs = [];
 $('#divDynamicFields').find("input").each(function () { 
     IDs.push({
        id: $(this).val()           
     });
});

console.log(IDs);

这将允许您通过ajax发送您想要通过数组传递的所有数据。

var IDs = [];

IDs.push([1, 2]);
IDs.push([2, 3]);

/* Loop Through Each element in 2D array */
$.each(IDs, function(key, value) {
  alert(value);
});
