我正在使用React,并希望从表单中检索POST参数(见下文):
<form ref='form' className="form">
<input type="text" className="signup-input" />
<input type="text" className="signup-input" />
<button className="btn btn-primary" onClick={this._onSubmitClick}>Submit</button>
</form>
在_onSubmitClick回调中,我希望实现与调用相同的结果,$(".form").serialize()但不使用JQuery.
我有以下两个超类:
class Parent1(object):
def on_start(self):
print('do something')
class Parent2(object):
def on_start(self):
print('do something else')
我希望有一个继承的子类可以为父母双方打电话.
class Child(Parent1, Parent2):
def on_start(self):
# super call on both parents
什么是Pythonic的方法呢？谢谢.
我正在关注Michael Hartl的Rails指南(第9章).当我尝试访问与用户配置文件对应的页面时,浏览器显示以下错误消息:

我有一个shell脚本,从基本目录递归搜索package.json并像这样运行npm test.
find "$parent_dir" -name package.json -maxdepth 2 -execdir npm test \;
我想以下列形式拦截测试失败:
npm ERR! Test failed. See above for more details.
npm ERR! not ok code 0
所以我可以让shell脚本退出并显示错误状态.
任何帮助表示赞赏.
我正在关注Michael Hartl的Rails指南,当我加载localhost:3000时,我在浏览器中收到以下错误消息:

我正在使用Emacs 24并希望在python模式下禁用自动完成模式,因此它不会与jedi冲突.我该怎么做呢(遗憾的是我不知道Emacs Lisp).以下是我在init.el中自动完成的当前设置:
;; auto-complete settings
(require 'auto-complete)
(add-to-list 'ac-dictionary-directories "~/.emacs.d/ac-dict")

我有一个简单的 package.json，它使用命令运行jest测试npm test。package.json 的相关部分如下所示：
{\n "scripts": {\n "test": "jest",\n "jest": {\n "scriptPreprocessor": "../shared/preprocessor.js"\n }\n}\nshell 脚本看起来像这样：
\n\nscript_dir="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"\nparent_dir="$script_dir/.."\n\necho\necho "Running all tests..."\nfind "$parent_dir" -name package.json -maxdepth 2 -execdir npm test \\;\n现在，当玩笑测试失败时，bash 脚本不会以失败状态退出。我希望这样做是为了使用 Jenkins 创建 CI 循环。笑话测试失败的示例如下：
\n\n FAIL js/components/__tests__/ExperienceCampaign-tests.js (13.19s)\n\xe2\x97\x8f ExperienceCampaign \xe2\x80\xba listening to ExperienceCampaignStore \xe2\x80\xba it starts listening when the component is mounted\n - Expected: true toBe: false\n at Spec.<anonymous> (/Users/jonathan/experience-studio/campaign/js/components/__tests__/ExperienceCampaign-tests.js:54:26)\n at Timer.listOnTimeout [as ontimeout] (timers.js:112:15)\n1 test failed, …我在我的项目中使用webpack和less-loader，在我的webpack配置中，我试图传递一个全局变量以在我的less文件中使用。该部分配置如下：
module: {
loaders: [
{
test: /\.less$/,
loader: 'style!css!less?'+JSON.stringify(
{globalVars: {staticDir: config.staticDir}}
)
}
]
}
我上面引用的配置文件是下面的json文件：
{
"staticDir": "'https://myendpoint.com'"
}
以下是使用此staticDir全局变量的less文件的一部分（我们称其为file.less）：
button.slick-prev {
left: 5px;
&:before {
url('@{staticDir}/images/some_image.svg');
}
}
但是，当我的资产捆绑在一起时，会出现以下错误：
ERROR in ./~/css-loader!./~/less-loader?{"globalVars":{"staticDir":"'https:/myendpoint.com'"}}!./path/to/file.less
Module not found: Error: Cannot resolve 'file' or 'directory' ./https:/myendpoint.com/images/some_image.svg in /Users/me/myprojects
@ ./~/css-loader!./~/less-loader?{"globalVars":{"staticDir":"'https:/myendpoint.com'"}}!./path/to/file.less 7:217947-218035
我正在尝试调试的两个错误：
https://myendpoint.com被解析为https:/myendpoint.com当我将端点硬编码到less文件中时，webpack会很好地打包我的资产。
最后一点：我staticDir在配置中设置为，"'https://myendpoint.com'"因为与绑定会"https://myendpoint.com"产生Module build failed: Unrecognised input错误。
