推荐答案

Gopal，

试试下面的代码

var grid = document.getElementById(<％= GridName.ClientID％>");
for(var i = 0; i< grid.rows.length; i ++){
var row = grid.Rows.getRow(i);
var ActivityTypeCell = row.getCell(10);
var ActivityTypeDropdown = ActivityTypeCell.getElement().childNodes [0];
var value = row.getCell(cellindex).getElement().childNodes [0] .value
}

将cellindex替换为文本框所在单元格的inddex.

快乐编码

Hi Gopal,

Try the below code

var grid = document.getElementById("<%= GridName.ClientID %>");
for (var i=0; i<grid.rows.length; i++){
var row = grid.Rows.getRow(i);
var ActivityTypeCell = row.getCell(10);
var ActivityTypeDropdown = ActivityTypeCell.getElement().childNodes[0];
var value= row.getCell(cellindex).getElement().childNodes[0].value
}

Replace the cellindex with the inxdex of the cell where the text box lies.

Happy Coding

这里我需要将textbox的值传递给javascript
带文本框模板字段的gridview

在调用每行的RowDataBound方法中，将客户端onkeyup添加到每个文本框.使用FindControl查找文本框，然后添加引用JS方法的onclick属性.

在JS方法中，获取文本框值，然后应用您的逻辑.

像这样的东西:

here I need to pass the value of textbox to javascript
gridview with textbox template field

Add a client side onkeyup to each textbox in a RowDataBound method where each row is called. Find the textbox using FindControl and then add onclick attribute referring a JS method.

In JS method, get the textbox value and then apply your logic.

Something like:

protected void GridView_RowDataBound(Object sender, GridViewRowEventArgs e)
{  
  TextBox tb = (TextBox)e.Row.FindControl("TextBox1");
  tb.Attributes.Add("onkeyup", "javascript: ValidateMe(this);"); 
}

function ValidateMe(currtextbox)
{
   // Use currenttextbox.value to validate
}
