javascript - java applet requestFocus() method error when called in js -


मुझे कॉल करने में त्रुटि है requestFocus () JS में विधि। 

  अनकॉट टाइप एरर: ऑब्जेक्ट # & lt; HTMLAppletElement & gt;  & lt; head & gt;  टैग  
  फ़ंक्शन ऑनलोड () {var विशेषता = {'id': 'क्लाइंट', 'संग्रह': 'client.jar', 'code': 'org.kuzy.client.ui.Applet.class', 'चौड़ाई': '100%', 'ऊंचाई': '100%'}; Var पैरामीटर = {'scriptable': 'true'}; परिनियोजन जाव.रनआपलेल्ट (गुण, पैरामीटर); Window.onfocus = फ़ंक्शन () {document.getElementById ("क्लाइंट")। RequestFocus (); }; }   
 एक अजीब विशेषता है, जब मैं क्रोम में डीबग में कोड चलाता हूं, तो सबकुछ ठीक काम करता है मैं आपकी सलाह के लिए आशा करता हूं।   
 
 
 मुझे यकीन नहीं है, लेकिन संभवतः जब आप विधि अनुरोध फोकस ) एप्लेट पहले से लोड नहीं है शायद जब आप डीबग करना चाहते हैं तो आप जेएस निष्पादन रोक रहे हैं और आप एप्लेट को लोड करने के लिए पर्याप्त समय दे रहे हैं। तो शायद आपको कॉलबैक या कुछ तंत्र की जरूरत है ताकि यह पता चले कि ऐपलेट कब तैयार है।

c - Performance of System() -

After the function in C, for the system (), it affects the hardware counters, so how do you order that The example displayed for the example you are trying to view lets the IM use the display API (PAPI) and the program is a precompiled matrix multiplication application. PAPI_start_counters (); System ("./matmul"); PAPI_read_counters (); // Print the values ​​PAPI_stop_counters (); I'm clearly missing a bit, but I'm trying to figure out what it is possible to say, counter receiving a program im running Is through use. With my tests I will get wild numbers like below, they are clearly wrong, just want to find out why total bicycle =========== 140733358872510 instructions complete =========== 4203968 Floating Point Instructions =========== Floating Point Operations =========== 4,196,867 Weight ======= ==== 140733358872804 store ======= ==== 4204037 branches taken =========== 15774436 System () Normally it is a very slow function, on Linux, it is ...

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:...

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...
