Here is a sample of my JavaScript function :
function NeedToExport()
{
alert('Time to export your data!');
}
Additionally, in my ASP.NET code behind :
Page.ClientScript.RegisterStartupScript(this.GetType(), "ExportKey", "NeedToExport();");
Even though the RegisterStartupScript function is successfully triggered, my JavaScript function does not execute as expected. For the second parameter, which represents the "Key of the starting script," I am unsure of what value should be used.
Typically, the script is displayed in the output without the <script> tags. This can be observed when using the browser's JavaScript console or examining the resulting HTML on the client side. It is important to become acquainted with these tools.
If you want the script tags to be added automatically, you can use a slightly different overload of the method.
Page.ClientScript.RegisterStartupScript(this.GetType(), "MyKey", "WantToSave();", true);
Alternatively, you have the option to manually add the script tags:
Page.ClientScript.RegisterStartupScript(this.GetType(), "MyKey", "<script>WantToSave();</script>");
The key string and the type used to register the control help in identifying the registered script uniquely. This comes in handy if you need to unregister it later or replace it with a different script. Therefore, the key does not have to be anything specific, just something unique.
One way to incorporate JavaScript code into your ASP.NET application is by utilizing the script manager's register startup script method. This method includes a boolean parameter, add script tags, which automatically adds the necessary script tags for you.
ScriptManager.RegisterStartupScript(this, this.GetType(), Guid.NewGuid().ToString(), "WantToSave();",true);
Give this a try:
var name = "NeedToRemember";
var script = "<script>alert('Don't forget to remember!');</script>";
Page.ClientScript.RegisterStartupScript(this.GetType(), name, script);
Alternatively, you can include a true parameter at the end of your function call to indicate including script tags.
Page.ClientScript.RegisterStartupScript(this.GetType(), "MyReminder", "NeedToRemember();",true);
Based on information from MSDN, when utilizing this particular overload, it is necessary to enclose your call within <script></script> tags. An example of how this would be done is as follows:
Page.ClientScript.RegisterStartupScript(this.GetType(), "MyKey", "<script>WantToSave();</script>");
Alternatively, you can opt for the other overload:
Page.ClientScript.RegisterStartupScript(this.GetType(), "MyKey", "WantToSave();", true);
This second option will either include them or not based on the boolean parameter provided.
