Ajaxpro indicates a resource download error, which is used by ajaxpro.

I have been modifying the project recently. I saw that the previous developers used ajaxpro and used it myself,

1. Web. cofig add nodes

<System. Web>
<Httphandlers>
<Add verb = "post, get" Path = "ajaxpro/*. ashx" type = "ajaxpro. ajaxhandlerfactory, ajaxpro"/>

 

2Add references to the CS File

Using ajaxpro;

 

3. CS file loading event

Protected void page_load (Object sender, eventargs E)
{

Utility. registertypeforajax (typeof (Class Name ));

 

4. Add [ajaxpro. ajaxmethod] To the Cs method.

[Ajaxpro. ajaxmethod]
Public String getname (string selectvalue)
{

// Note: 1. return values are required; 2. Controls are not available in the method body; 3. It is best to have input parameters. Sometimes, the error "download of specified resource error" is reported"

// Error
Return selectvalue;
}

 

5. Front-end JS use

<SCRIPT type = "text/JavaScript" Language = "JavaScript">
Function Tan ()
{
VaR A = Class Name. getname ("1111"). value;
Alert ();
}

</SCRIPT>

6. Controls

<Input type = "button" id = "btn1" value = "Click here" onclick = "Return Tan ()"/>
