I want to systematically study Ajax. I didn't expect to drag a scriptmange, But I encountered the "Microsoft JScript runtime error: 'sys 'is undefined" error, and Google gave me a hand, I found that some friends had encountered a similar error. paste the method,

Ajax. net1.0 official version

<Httphandlers> <remove verb = "*" Path = "*. asmx"/>
<Add verb = "*" Path = "*. asmx" Validate = "false" type = "system. Web. Script. Services. scripthandlerfactory"/>
<Add verb = "Get, head" Path = "scriptresource. axd "type =" system. web. handlers. scriptresourcehandler, system. web. extensions, version = 1.0.61025.0, culture = neutral, publickeytoken = 31bf3856ad364e35 "Validate =" false "/>
