casperJS失败注入jQuery [英] casperJS failed Injecting jQuery

问题描述

有谁知道我遇到了怎么回事

Does anyone know how come I am encountering

[warning] [phantom] Failed injecting %s client side. 
Failed injecting includes/jquery-1.10.2.min.js client side 

当我已包含

'includes/jquery-1.10.2.min.js' 

在Casper构造函数中。有人在此处发布了类似的问题： https://groups.google.com/论坛/＃！msg / casperjs / hY4ziaoXIEE / YFi8Sj4JysMJ ，但我不明白他们如何在他们的解决方案中加入casper.evaluate（）：

within the Casper constructor. Someone posted a similar question here: https://groups.google.com/forum/#!msg/casperjs/hY4ziaoXIEE/YFi8Sj4JysMJ, but I do not understand how they have incorporated the casper.evaluate() in their solution:

casper.then( function() {
this.evaluate(function($) {
console.log($('title').text());
}
}); 

推荐答案

我不记得曾经能够使用CasperJs构造函数的clientScripts选项注入脚本。相反，我总是找到以下工作。

I don't remember ever being able to inject scripts using the clientScripts option of the CasperJs constructor. Instead I have found the following works for me always.

casper = require('casper').create();
casper.start();
casper.open('some url');
casper.then(function doSomething() {
    this.page.injectJs('relative/local/path/to/jquery.js');
    var items = this.evaluate(function () {
        return $('div.someClass'); // jquery here
    });
});
