In the development of ASP.NET, we often use client code, such as JavaScript
Of course, you can embed in HTML. But here is what the server is dynamically added to the client to add client code.
1. Use the RegisterClientScriptBlock method for the Page control:
DIM S as string = ""
S = "functon alertmsg () {"
S = "Alert (" Error ");}"
S = ""
IF (Not is ClientscriptBlockRegistered ("XXX")).
RegisterClientScriptblock ("xxx", s)
END IF
Add to Button's Click event to the server side:
Button.attributes.add ("onclick", "alertmsg ()")
This way, you can add this JavaScript code to the client.
2. When running, the client code is added directly by adding the properties of the control.
Such as:
Button.attributes.add ("onclick", "Alert ('Error!');")
Both methods can achieve the same effect.
