naming conventions - Can I BEGIN a CSS selector ID or Class with an underscore? -


इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 8 जवाब

    उदाहरण के लिए: # _id-name {} और ._ class-name {} मुझे पता है कि शुरुआती दिनों में अंडरस्कोर की अनुमति नहीं थी - साथ ही साथ डबल हाइफ़न ( - < / code>)। लेकिन क्या यह ठीक है और क्या सभी ब्राउज़र एक वर्ग या आईडी को पढ़ने / समझने में सक्षम होंगे यदि यह _ से शुरू होता है?

    मैं बस सीएसएस के बजाय मेरे कोड के आधार पर html पर आधारित हूं। संक्षेप में, आईडी को जाहिरा तौर पर एक अक्षर से शुरू होना चाहिए (<

  • कोड> ए-ज़ा-जेड ) और इसके बाद किसी भी अन्य अक्षर, संख्या, अंडरस्कोर या डैश हो सकते हैं व्यावहारिक रूप से, आप आईडी को - या _ के साथ शुरू कर सकते हैं और यह काम करेगा: लेकिन एक संख्या से शुरू करना नहीं काम करते हैं।

    हालांकि ये प्रतिबंध सीडीएटीए सूची वाले वर्गों पर लागू नहीं होते हैं, लेकिन व्यावहारिक रूप से ऐसा ही लगता है:

    इसलिए आपको एक सुसंगत और भविष्य के सबूत मिलते हैं ब्राउज़र का अनुभव, मैं आईडी, वर्ग के नामों आदि के साथ कुछ दिखने से बचने का प्रयास करूंगा।

python - how we can use ajax() in views.py in django? -

I have a little code here. Could you please tell me what this code really does? please. Here in the AJAX call: $ .ajax ({url: "{% url} upload_document '%}", type: "POST", data : {Csrfmiddletoken: document.getElementsByName ('csrfmiddletoken') [0] Price, Title: document.getElementById ('title'). Value, // document: document: document.getElementById ('document'),}, datatype: "Jason", success: function (feedback) {if (feedback == "true") {// success} other {// attachment errors}}}); How AJAX works in the Django and how we can see the AJAX request. Here is the idea of ​​my thoughts def upload_document (requested): Print request. POTT print request FILES if request.is_ajax (): If request.method == 'POST': form = UploadForm (request.POST, request.FILES, user = request.user) if form.is_valid (): Form.save () return HTTPPCS (SimpleJason Dumps ('True'), Mime Type = 'App / Jason') Other:...

matlab - Using loops to get multiple values into a cell -

I have 31 topics (S1, S2, S3, S4, etc.) 3 images in each topic, opposite 1 IMG, Contrast 2 IMG and Contrast 3 Are IMG I p In a NX1 cell named P, I would like to use a loop to get all the paths of contrasts from all the subjects: data / S1 / contrast1.img / S1 / contrast2.img data / S1 / contrast3.img data / s2 / contrast1.img data / S2 / contrast2.img Data / S2 / contrast3.img ... Data / S31 / contast3.img This is what I've tried: A = {'S1', 'S2', 'S3', ..., 'S31'}; % All topics C = {'contrast1.img', 'contrast2.img', 'contrast3.img'}; For each = P = cell (31 * 3,1) for each topic, the required contrast images: Length = A for Jammu = 1: Length (C) P {j} = spm_select ('FPList', Fullfile (data_path, q {i}) sprint ('% s', cell2mat (c))); % Of each topic is to select three contrast images, it works in my script, it is probably not 100% correct, because I had to simplify this example.

python - Sequence Pattern recognition with Pybrain -

Image
I am constantly trying to use recurrent neural networks to classify a series of data. To be more specific, I have a sequence of sensor reading (which is continuous over time), I have to learn an algorithm which can detect the state related to this pattern, given the readings change. Example: Time step_1: 1.4 Time step_2: 1 Time step_3: 0.8 State = New Sequence: Time Phase 1: 0.4 Time Phase 2: 0.3 Time Phase 3: 0.1 State = Sitting I actually have 12 censors, I'm just showing a sequence of numbers for convenience. (Numbers are not real, I'm just trying to fulfill this idea)! I am trying to make my network with PyBrain RNN, however, I can not get a Data Set Container that can detect it, like information I tried to use sequential data But after some testing I came to know that this number is the next element in the sequence of numbers. Here's how I prepare my dataset: self.alldata = SequentialDataSet (ds.num_features, 1) # Now add samples to the dat...
