{
Button btnSubmit1 = (Button)TwoInstances1.FindControl("btn_submit");
btnSubmit1.Attributes.Add("onClick", "fnCheck()");
btnSubmit1.Click += new EventHandler(btnSubmit1_Click);
Button btnSubmit2 = (Button)TwoInstances2.FindControl("btn_submit");
btnSubmit2.Attributes.Add("onClick", "fnCheck1()");
btnSubmit2.Click += new EventHandler(btnSubmit2_Click);
}
void btnSubmit1_Click(object sender, EventArgs e)
{
((TextBox)TwoInstances2.FindControl("txt_text")).Text += ((TextBox)TwoInstances1.FindControl("txt_text")).Text;

void btnSubmit2_Click(object sender, EventArgs e)

给我解决方案。
If i give the same javascript code in seperate file it is not working. Can anyone plz
give me the solution for this.
推荐答案
你不能将服务器端代码用于单独的JS文件中/>
You can't use server side code into a separate JS file
'<%=((TextBox)TwoInstances1.FindControl("txt_text")).ClientID%>'
解决方案：
创建将参数函数放入JS文件
Solution:
create function with parameter into a JS file
function fnCheck(a) {....}
并从aspx页面调用该函数，例如
and call the function from aspx page like
<script>
fnCheck('<%=((TextBox)TwoInstances1.FindControl("txt_text")).ClientID%>');
</script>
