How to call background methods by ajax
This article mainly introduces how to call the background method of ajax, the article introduces in great detail, has a certain reference value, interested friends must read it!
There are three methods I have used:
1 add a hidden button to the page, define the event, and then execute the $("# hide btnID"). Click () of js to execute the background method
2 use ajaxPro to execute
3 execute with the url: page address / (static) method name of ajax
In this method, the method must be static, so for example, on the page _ default, the example is as follows
The copy code is as follows:
Public partial class _ Default: System.Web.UI.Page
{
Static int sVar = 1
Int abc = 3
Int result
[WebMethod]
Public static string AjaxGetMethod ()
{
SVar = 2; / / static variables can be called directly
_ Default d = new _ Default (); / / result,abc cannot be used if it is not instantiated
NoStaticFun nsf = new NoStaticFun (); / / test cannot be used without instantiation
D.result = nsf.test ()
D.result = d.abc
Return d.result
}
}
Public class NoStaticFun
{
Public int test ()
{
Return 2
}
}
In this example, I've marked it, and I'd like to discuss with you what other better methods are, or how you apply them.
