Question

我正在使用CasperJS，需要选择一个包含空格的类。做了一些谷歌搜索，但没有得到什么问题。

HTML内容：

<div id="member-1" class="letters vcard known"> 
 ...
</div>

CasperJS断言

casper.test.assertExists('div.letters vcard known');

也试过

casper.test.assertExists('div.letters\ vcard\ known');

结果

FAIL Found an element matching: div.letters vcard known
#    type: assertExists
#    subject: false
#    selector: "div.letters vcard known"
[warning] [phantom] looks you did not use begin() which is mandatory since 1.1

Answer 1

尝试使用：

casper.test.assertExists(div[class*="letters"]);

（如果您没有其他以“字母”开头的课程）

但我认为你有三个不同的类：

casper.test.assertExists('div.letters.vcard.known');

casperJS assertExists不传递带空格的类
