如何从JavaScript向服务器端发送二维数组(C#) [英] how to send two dimensional array from javascript to server side(c#)

问题描述

大家好，

我在Java脚本中有二维数组.单击提交按钮时，这两个二维数组必须通过服务器端.

Hi All,

I have two dimensional array in java script. these two dimensional array have to pass server side when submit button is clicked.

I think this would suit you.

C#无法识别Javascript数组.因此，您需要做一些技巧，将javascript数组序列化为字符串，以便可以在C#中反序列化该字符串.

您可以使用自定义序列化将数组转换为字符串.
在示例中，我遵循json字符串，但是您可以使用任何逻辑.

Javascript array cannot be recognized by C#. So, you need to do a trick to serialize the javascript array to a string so that the string can be deserialized in C#.

You can use your custom serialization to convert an array to a string.
In the example I follow the json string, but you can use any logic.

<script language="javascript">
skillArray = new Array(5)

skillArray [0] = new Array(2)
skillArray [0][0] = "Jon"
skillArray [0][1] = "DOT.NET"

skillArray [1] = new Array(2)
skillArray [1][0] = "Tim"
skillArray [1][1] = "C++"

skillArray [2] = new Array(2)
skillArray [2][0] = "Dan"
skillArray [2][1] = "C"

skillArray [3] = new Array(2)
skillArray [3][0] = "Alex"
skillArray [3][1] = "Java"

skillArray [4] = new Array(2)
skillArray [4][0] = "Robert"
skillArray [4][1] = "Perl"

var s='''';
for (i=0;i<skillarray.length;>  for (j=0;j<2; j++) {
     if(j==0)
       s += ''"'' + skillArray[i][j] + ''"'' + '':'';
     else
       s += ''"'' + skillArray[i][j] + ''"'';
  }
  s += ",";
}
alert(s);
</script>

所以字符串看起来像
"Jon":"DOT.NET"，"Tim":"C ++"，"Dan":"C"，"Alex":"Java"，"Robert":"Perl"

用户Ajax将字符串发送到C#(后面的代码).
用户拆分功能可首先拆分主要子字符串
"Jon":"DOT.NET"
"Tim":"C ++"
"Dan":"C"
"Alex":"Java"
"Robert":"Perl"

现在使用循环来迭代每个元素，并用:"
拆分每个元素 因此，您可以在C#中创建与javascript相同的二维数组.

欢呼

So the string will look like
"Jon":"DOT.NET","Tim":"C++","Dan":"C","Alex":"Java","Robert":"Perl"

User Ajax to send the string to C# (code behind).
User split function to split first the primary substring
"Jon":"DOT.NET"
"Tim":"C++"
"Dan":"C"
"Alex":"Java"
"Robert":"Perl"

Now use a loop to iterate each element and split each element with ":"
Thus you can create a 2 dimensional array in C# same as javascript.

cheers
