javascript - When I add new style with jQuery will it overwrite css? -

-

मान लें कि मेरे पास यह jQuery कोड है 

  $ ('head')। '& Lt; शैली & gt; शरीर, html {मार्जिन: 0! महत्वपूर्ण;} .. और भी ... & lt; / style & gt;');

क्या यह वर्तमान सीएसएस को ओवरराइट करेगा (ध्यान दें ! महत्वपूर्ण ) मैंने अपने ब्राउज़र में इसे परीक्षण किया है और यह अपेक्षा के अनुरूप काम कर रहा है और मौजूदा सीएसएस को ओवरराइट कर रहा है।

मैं मूल रूप से क्या चाहता हूं। CSS फ़ाइल के बिना कुछ सीएसएस जोड़ना है।

चूंकि आपने एक सीधा शैली टैग लागू किया है, यह किसी भी सीएसएस पर अधिलेखित होगा। महत्वपूर्ण हमेशा किसी भी वर्ग पर लिखता है, और आमतौर पर बुरा व्यवहार माना जाता है। क्लास क्यों नहीं जोड़ें?

ruby on rails - Apipie interferes with proper error codes -

I can not find this little bit in the API's docs. Let me make this special AP ready, and I thought I would document it with APP, all fine and dandy, and the ultimate verification is good, but I feel that the response to failure in verification I can not seem to throw the right HTTP code in For example, I have this post / user method, which obviously makes the user in my database good, right? Well, this is something wrong, and it's ok, but if, say, I throw the standards that it does not pass the validity of the apipie, chops apipies and throws a good old-fashioned error, if something is wrong, 422 responds with a fixed unit failure / error: post '/users.json' ,: user = & gt; D Apipie :: ParamInvalid: Invalid parameter 'Email' value "": Regular expression / [a-zA-Z0-9 will match - -] + \ @ [a-zA-Z0-9 \ -.] + \.
