Question

On a click event I call the same JavaScript function 3 times but the javascript function itself only execute once.

BLL.Common.executeJSFunction("DoSomething();");
BLL.Common.executeJSFunction("DoSomething();");
BLL.Common.executeJSFunction("DoSomething();");

The method:

public static void executeJSFunction(string jsFunction)
    {
        var page = HttpContext.Current.Handler as Page;
        ScriptManager.RegisterStartupScript(page, page.GetType(), "Exec", jsFunction, true);
    }

Java script function:

function DoSomething()
{
   alert('Hello Word');
}

ps: There is a ScriptManager and a update panel on the page just in case….

You overwrite the key with each function call, try:

BLL.Common.executeJSFunction("DoSomething();", "Exec1");
BLL.Common.executeJSFunction("DoSomething();", "Exec2");
BLL.Common.executeJSFunction("DoSomething();", "Exec3");

public static void executeJSFunction(string jsFunction, string key)
{
    var page = HttpContext.Current.Handler as Page;
    ScriptManager.RegisterStartupScript(page, page.GetType(), key, jsFunction, true);
}
