对163所有新闻的截图例子这只是一个casper1.0.x版本的语法例子。

//casperjs /mnt/D/work_documents/workspace_ide/phantomjs_casperjs/casperjs/list_163_new.js

var casper = require("casper").create({
    verbose: true,
    logLevel: "info",
    viewportSize: [1366, 678],
    pageSettings:{
        //定义一些变量
    },
    clientScripts: [
        //"http://code.jquery.com/jquery-1.9.0.js"
    ],
    onAlert: function (msg) {
    },
    onError: function () {
        console.log("错误","error");
    }
});
var utils = require("utils");
var url = "http://news.163.com";
var d1 = new Date();
var count=0; //一个计数器
var links = []; //用于记录所有匹配的链接

console.log("开始启动程序");

//启动
casper.start(url, function () {
    console.log("打开标题:"+this.getTitle());
});


casper.then(function () {
    console.log("匹配链接");
    links = this.evaluate(function () {
        return [].map.call(__utils__.findAll('.area-main .main-list a'), function (node) {
            return node.getAttribute('href');
        });
    });
});



casper.then(function(){
    console.log("打开链接并截图");
    this.each(links, function (self, link) {
        console.log(link);
        self.thenOpen(link,function(){
            var path=link.substring(7);//去掉http://
            console.log("截图["+links.length+":"+count+"] title=>"+this.getTitle());
            this.capture("/mnt/D/work_documents/workspace_ide/phantomjs_casperjs/images/"+path+".png");
            count++;
        });
    });
});


casper.then(function(){
    console.log("计算耗时");
    var d2=new Date();
    var i=d2.getTime()-d1.getTime();
    console.log("共使用了 "+(i)/1000+" s导出"+count+"张图片.");

删除持续集成hudson里面的一些部署历史

// casperjs /mnt/D/work_documents/workspace_ide/phantomjs_casperjs/casperjs/hudson_dev_cpm_delete.js
casper = require("casper").create({

    },
    onAlert: function (msg) {
        this.echo("Alert:\n" + msg);
    }
});
//要删除任务名称
jobName="dev_cpm_disabled";
//hudson的地址
url = "http://192.168.0.170:8081/hudson3/";
//删除最大历史记录数,用于循环
max_record=100;

//启动
