Java脚本数组动态declearation [英] Java script array declearation dynamically

问题描述

当我不知道维度时，如何在java脚本中声明数组，

How to declare array in java script when i dont know the dimention,

因为它将动态形成，具体取决于从数据库创建的行。

as it  will form dynamically depending on the rows created from the database.

我根本无法获得运行时的行数，我将需要为我的工作创建二维数组，任何人都可以帮助我。

I dont have any way to get the rows it comes on run time based on that i will require to create two dimention array for my work  can any body help me.

 

推荐答案

javascript中的数组是无限的，它会随着你的填充而增加。您可以通过以下方式从代码中创建数组：

the array in javascript is unlimited, it grows in dimensions as u fill it up. you can create the array from your code in this way:

 

StringBuilder script = new StringBuilder（）;

StringBuilder script = new StringBuilder();

   &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;   script.Append（"< script> var list = new Array（）;"）;

                script.Append("<script>var list = new Array();");

   &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;   for（int i = 0; i< DataTable.Rows.Count; i ++）

                for (int i = 0; i < DataTable.Rows.Count; i++)

   &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;   {

                {

   &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;   script.Append（@" list [" + i + @"] =""" +  DataTable.Rows [" ColName"]  + @""" ;; "）;

                    script.Append(@"list[" + i + @"]= """ + DataTable.Rows["ColName"] + @""";");

   &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;  }

                }

   &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;   script.Append（"< / script>"）;

                script.Append("</script>");

   &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;   Page.RegisterClientScriptBlock（" my script"，script.ToString（））;

                Page.RegisterClientScriptBlock("my script", script.ToString());

 

如果你在另一个数组中设置一个数组，你可以创建一个二维数组

and you can create a 2 dimensional arrays if you set an array inside another one
