我的带有ajax的java脚本函数必须移入java类: -
<script type="text/javascript">
$(document).ready(function(){
var polyLat = new Array();
polyLat[0] = 10.194027;
polyLat[1] = 10.226975;

polyLat[6] = 9.899107;
polyLat[7] = 9.993088;
polyLat[8] = 10.081425;
polyLat[9] = 9.992266;
polyLat[10] = 10.194027;//First point repeated to close polygon
var polySides = (polyLat.length)-1;//number of points in polygon
//vertical Longitude coordinates of polygon
var polyLng = new Array();
polyLng[0] = 76.201205;
polyLng[1] = 76.375022;

polyLng[8] = 76.317492;
polyLng[9] = 76.267905;
polyLng[10] = 76.201205;//First point repeated to close polygon
//Coordinates for bounding box
var maxLat = Math.max.apply(null,polyLat);
var minLat = Math.min.apply(null,polyLat);
var maxLng = Math.max.apply(null,polyLng);
var minLng = Math.min.apply(null,polyLng);
$.post('outboundupd.jsp',
{

function(response,status,xhr)

我需要在服务器启动后定期执行上面的代码,所以我使用了上下文列表器并在新的java类中实现了runnable,下面是我的java类: -
package com.my.classes;
public class obrecord implements Runnable {
@Override
public void run() {
// TODO Auto-generated method stub
}
}
现在,我需要在下面的java类中执行上面的javascript代码,以便在服务器启动时定期运行它。有没有办法做到这一点?或者有没有其他有效的方法来完成工作?任何代码都受到高度赞赏,并提前感谢。
答案 0 :(得分:0)
创建一个将定期调用的函数。 并使用javascript的这个功能。
var intervalID = setInterval(function_name(), 5000);
无需编写java代码。
我认为这个问题有助于: Is there any way to call a function periodically in JavaScript?
