if you have java script function on aspx page lets say "MyFunc()"

and if you want to call this function on specific button click then

write Add attribute to your button in code behind page as show in below

C#

btnSave.Attributes.Add("onclick","return MyFunc()");

if you want to call java script on dropdown value change then call as below

C#

ddlStatus.Attributes.Add("OnChange","MyFunc()");

if you want to call java script on page load call function below in page load

C#

ClientScript.RegisterStartupScript(GetType(), "key", "Test();", true);

Where you want to call the function inside Code behind event/function.
