动态获取文本框的ID并分配给变量 [英] To get ID of Textbox dynamically and assign to a variable

问题描述

I have a Grid Under the  ContentPlaceholder here the grid is Dynamic where it rows will be increasing accordingly to the Values i pass from Database.
On pageload if my Grid contains 5rows for example, i want to get the ID of all the Textbox which is in Grid Dynamically and assign it to the Variable..
How to do it..

When i Run the page and checked view source from browser i got my Textbox name like this

"ctl00_MainContent_gvtemp_ctl00_ctl04_txtDescription"
"ctl00_MainContent_gvtemp_ctl00_ctl06_txtDescription"
"ctl00_MainContent_gvtemp_ctl00_ctl08_txtDescription"
"ctl00_MainContent_gvtemp_ctl00_ctl10_txtDescription"
"ctl00_MainContent_gvtemp_ctl00_ctl12_txtDescription"

I need to Pass those Id to Var ids like below..

var ids = ["ctl00_MainContent_gvtemp_ctl00_ctl04_txtDescription",
                "ctl00_MainContent_gvtemp_ctl00_ctl06_txtDescription",
                "ctl00_MainContent_gvtemp_ctl00_ctl08_txtDescription",
                 "ctl00_MainContent_gvtemp_ctl00_ctl10_txtDescription",
                 "ctl00_MainContent_gvtemp_ctl00_ctl12_txtDescription",
                  "ctl00_MainContent_gvtemp_ctl00_ctl14_txtDescription",
                  "ctl00_MainContent_gvtemp_ctl00_ctl16_txtDescription"];



Here my Grid Coding:

 <telerik:RadGrid ID="gvtemp" AllowSorting="false" AllowPaging="false" runat="server"

                                                    CssClass="grid tBorder" ShowFooter="false" AllowMultiRowSelection="false" AllowMultiRowEdit="false"

                                                    ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center"

                                                    AlternatingItemStyle-HorizontalAlign="Left" HorizontalAlign="Center">

推荐答案

我试过并获得文本框的ID，如



var masterTable =

I tried and got the ID of the textbox like

var masterTable =

find（<％= gvtemp。 ClientID％>）。get_masterTableView（）;

var row = masterTable.get_dataItems（）;

var ids = new Array（row）;

for（var i = 0;我< row.length; i ++）{

var rowid = masterTable.get_dataItems（）[i] .findElement（txtDescription）。id;

ids [i] = rowid;

}

find("<%= gvtemp.ClientID %>").get_masterTableView();
var row = masterTable.get_dataItems();
var ids = new Array(row);
for (var i = 0; i < row.length; i++) {
var rowid = masterTable.get_dataItems()[i].findElement("txtDescription").id;
ids[i] = rowid;
}
