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 () {
