This overload of the RegisterClientScriptInclude method takes key and url parameters to identify the script, as well as a type parameter to specify the identification of the client script include. You specify the type based on the object that will be accessing the resource. For instance, when using a Page instance to access the resource, you specify the Page type.
Note |
|---|
To resolve the client URL, use the ResolveClientUrl method. This method uses the context of the URL on which it is called to resolve the path. |
This method adds a script block at the top of the rendered page.
The following code example demonstrates the use of the RegisterClientScriptInclude method. Note that if the logic to check for the existing client script include were removed, there would still not be duplicate client scripts in the rendered page because the RegisterClientScriptInclude method checks for duplicates. The benefit of checking is to reduce unnecessary computation.
This example requires a JavaScript file named Script_include.js with the following contents:
function DoClick() {Form1.Message.value='Text from include script.'}
