# Call javascript's function from code behind

I use below code for call [javascript](https://www.mindstick.com/articles/874/how-to-create-watermark-text-for-textbox-by-using-javascript)'s [function](https://www.mindstick.com/articles/13001/multi-statement-table-valued-user-defined-function-in-sql-server) from [code behind](https://www.mindstick.com/forum/2090/send-data-from-asp-dot-net-code-behind-to-a-javascript-function) but doesn't call function

```
//C#Page.ClientScript.RegisterStartupScript(this.GetType(), "close panel", "CloseFunction()", true);//javascriptfunction CloseFunction() {            alert("call");            }
```

Hi Chintoo, \
Use this:

Page.ClientScript.RegisterStartupScript(this.GetType(), "close panel", "CloseFunction()",

true);
