Output client-side console with casper/phantomjs
提问by Abhik Bose Pramanik
Going through the casperjs documentation I couldn't find where I could see the console.log from client-side javascript. Is this possible?
通过 casperjs 文档，我找不到可以从客户端 javascript 看到 console.log 的地方。这可能吗？

I'm not really sure to fully understand your question, but you can do something like the following:
我不确定是否完全理解您的问题，但您可以执行以下操作：
var casper = require('casper').create({
logLevel: "debug"
});
casper.on('remote.message', function(message) {
this.echo(message);
});
casper.start('http://google.com/', function() {
this.evaluate(function sendLog(log) {
// you can access the log from page DOM
console.log('from the browser, I can tell you there are ' + log.length + ' entries in the log');
}, this.result.log);
});
casper.run();
Output:
输出：
$ casperjs log.js
from the browser, I can tell you there are 4 entries
