How to pass the value of a textbox in a datagrid to javascript

Question

我的数据网格中有一个文本框，其ID需要传递给javascript。我的数据网格的ID为Datagrid1，文本框的ID为txtItem。所有这些都在contentplaceholder内部。现在，我将文本框的ID传递为ct100_ContentPlaceholder1_Datagrid1_txtItem。我的JavaScript中出现错误“对象引用未设置为对象实例”。如何将datagrid中此文本框的ID传递给javascript。

If you have a textbox inside your grid probably you have multiple instances of it, with JQuery you can access all textboxes inside your grid like that :

function getTextBoxesInsideGrid()
{
    var gridClientID = '<%= grid.ClientID %>';
    jQuery.each($("#" + gridClientID + " input[type='text']"), function ()
    {
      var textValue = this.val();
      // do something
    });
}
