Javascript Value 由几个词组成 [value=dog crazy]

Question

感谢本论坛的帮助，我的代码能够正常工作:

// ==UserScript==
// @name        PARINGO
// @description Auto select rpt radio button
// @namespace   PARINGO
// @include     https://docs.google.com/spreadsheet/viewform?formkey=dG1fdUU1bTR5R1l3dmtGS095QVYxZlE6MQ
// @require     http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js
// @grant       GM_addStyle
// @version     1
// ==/UserScript==
/*- The @grant directive is needed to work around a design change introduced
    in GM 1.0.   It restores the sandbox.
*/
//-- Note that :contains() is case-sensitive
var questionLabel   = $(
    "label.ss-q-title:contains('How much is 1+1') ~ ul.ss-choices"
).first ().find ("input[type=radio][value=2]");
questionLabel.prop ('checked', true);

var questionLabel   = $(
    "label.ss-q-title:contains('How much is 4+2') ~ ul.ss-choices"
).first ().find ("input[type=radio][value=6]");
questionLabel.prop ('checked', true);

这个脚本的作用是检查标签并标记正确答案。但是如果响应由两个或多个单独的词组成。没有作品例如:

var questionLabel   = $(
        "label.ss-q-title:contains('How much is 4+2') ~ ul.ss-choices"
    ).first ().find ("input[type=radio][value=dog crazy]");
questionLabel.prop ('checked', true);

这适用于谷歌文档中的表单: Form Google Docs

任何人都可以告诉我该值如何接受单独的单词？

("input[type=radio][value=dog crazy]")

如果一个属性由多个单词组成，那么您必须使用这样的引号:

"input[type=radio][value='dog crazy']"
