This article is to share with you about the application of ajax json value transfer in jsp pages, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article. Let's take a look at it with the editor.

Jsp page:

The code is as follows:

$(document) .ready (function () {

SetInterval (function myTimer ()

{

/ / alert ('a')

GetViews ()

}, 1000)

});

/ / play

Function getViews () {

$.ajax ({

'url': "${pageContext.request.contextPath} / video/getVideos.action?r=" + Math.random () + "& open=1"

'data':''

'dataType': 'json'

'type': 'get'

'error': function (data) {

Alert ("error")

Return false

}

'success': function (data) {

If (null! = data & &'! = data) {

/ / alert (data.updateFlag)

If (data.updateFlag==0) {/ / if data.updateFlag=0 does not refresh

/ / alert ("data.updateFlag=0")

}

Else {

If (data.videoIds! = null & & data.videoIds! = "") {

Var listIds=data.videoIds

Var iTunes 0
