The purpose of ajax technology is to enable javascript to send http requests, communicate with the background, and obtain data and information. The principle of ajax technology is to instantiate a xmlhttp object and use it to communicate with the background. The process of ajax communication does not affect the execution of subsequent javascript, thus achieving asynchronism.

The following is an example.

Paging ajax application

Function fenye (cpage) {

Location = "/ list?cpage=" + cpage

}

Function qx () {

$(".ch") .each (function () {

$(this) .attr ("checked", true); / / false

})

}

Function fx () {$(".ch") .each (function () {$(this) .attr ("checked",! $(this) .attr ("checked", true);})} function plsc () {var ids = "; $(" .ch: checked ") .each (function () {ids+=", "+ $(this) .attr ();}) ids = ids.substring (1) Location= "plsc?ids=" + ids;}

@ RequestMapping ("/ plsc")

Public String plsc (String ids) {

System.out.println (ids)

String [] split = ids.split (",")

For (String string: split) {

Zm.deleteByPrimaryKey (Integer.valueOf (string))

}

Return "redirect:lista"

}
