我使用传统的JavaScript（不是JQUERY）从客户端站点的Asp.net GridView读取值但是在我多次尝试之后，我发现我不知道如何从纯粹的javascript中读取BoundField Column中的值“Visile = False”。

var grid = document.getElementById("<%= GridView1.ClientID %>");
var OutputString = "";
if (grid.rows.length > 0) 
{
for (i = 1; i < grid.rows.length - 1; i++) 
{
    for (j = 0; j < grid.rows[i].cells.length; j++) 
    {
        if (j == 1) 
        {
        OutputString += "grid.rows[i].cells[" + j + "]  :" + grid.rows[i].cells[j] +
        "\ngrid.rows[i].cells[" + j + "].innerText :" + grid.rows[i].cells[j].firstChild.value;
        OutputString += "\n\n";
        } 
        else 
        {
            OutputString += "grid.rows[i].cells[" + j + "]  :" + grid.rows[i].cells[j] +
            "\ngrid.rows[i].cells[" + j + "].innerText :" + grid.rows[i].cells[j].innerText;
            OutputString += "\n\n";
        }
    }   
}
}

输出

grid.rows[i].cells[0]  :[object]
grid.rows[i].cells[0].innerText :Abd pant XXXL

grid.rows[i].cells[1]  :[object]
grid.rows[i].cells[1].innerText : 12

grid.rows[i].cells[2]  :[object]
grid.rows[i].cells[2].innerText :Pieces

grid.rows[i].cells[3]  :[object]
grid.rows[i].cells[3].innerText :1 

grid.rows[i].cells[4]  :[object]
grid.rows[i].cells[4].innerText :Delete 

grid.rows[i].cells[5]  :[object]
grid.rows[i].cells[5].innerText :Edit

在Javascript中，这是否可以从bondfield中读取可见的虚假值？

[更新]
我只从Textbox模板字段和BoundField 得到的所有输出都不是“Visible = False”。

请让我知道方式，我们将不胜感激。

Answer 1

Visible控制=＆＃34; false＆＃34;将不会呈现，因此不会生成HTML。

如果你想让你的控件不可见但仍然引用它们，首先删除Visible =＆＃34; false＆＃34;然后你可以在控件上使用CSS：

style="display:none;"

或者你可以在RowDataBound事件被渲染后隐藏GridView列（前四个BoundFields）：

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
{
    e.Row.Cells[column_index].Visible = false;
}

Javascript阅读ASP GridVIEW BoundField列，显示为false
