Question

我试过这段代码：

        var casper = require('casper').create();
        var mouse = require("mouse").create(casper);
        phantom.casperTest = true;
        phantom.cookiesEnabled = true;

        phantom.addCookie({
            'name': 'authToken',
            'value': '88f115b38585155c1',
            'domain': 'localhost',
            'path': '/'
        });
        phantom.addCookie({
            'name': 'activationId',
            'value': '1',
            'domain': 'localhost',
            'path': '/'
        });
        phantom.addCookie({
            'name': 'userId',
            'value': '1',
            'domain': 'localhost',
            'path': '/'
        });
        casper.start('http://localhost/history.php', function() {
            casper.on('remote.message', function(message) {
                console.log(message);
            });
            casper.thenOpen('http://localhost/history.php', function() {
                this.page.render('cookie.jpeg');
                this.evaluate(function() {
                    console.log('cookie it here');
                    console.log("title--" + document.title);
                    console.log(document.cookie);
                });

            });
        });

        casper.then(function() {
            this.test.assertTextExists('Yesterday');
        });

        casper.run();

它给了我这个错误

为什么我收到此错误？我的饼干是设置还是未设置？如何在casperJS中用表格计算具有特定类名的Li的总数？

Answer 1

回答你的意见：嗯，这取决于，我不知道你是否掌握了CSS选择器：

this.click('li.history:nth-of-type(2) a');

但是小心，它从其父级获取第二个li元素，因此classname不会过滤搜索（它仅用于获取正确的父级）。使用xpath（或jQuery与eq（））更直观（如果我记得很好，就像使用xpath那样）：

var x = require('casper').selectXPath;
this.click(x("li[@class='layout_right'][2] a"));

AssertionError：在文档体casperJS / phantomJS中查找文本以及如何使用casperJS计算具有特定类名的Li的总数
