javascript - Exclusive selecting list elements -

-

मेरे पास एक अनोर्ड सूची है: 

  & lt; ul & gt; & Lt; li एनजी-क्लास = "{'सक्रिय': चयनित}" एनजी-क्लिक = "चयनित =! सिल्क्टेड" & gt; स्टफ़ 1 & lt; / li & gt; & Lt; li ng-class = "{'सक्रिय': चयनित}" एनजी-क्लिक = "चयनित =! सिल्क्टेड" & gt; स्टफ 2 & lt; / li & gt; & Lt; li एनजी-क्लास = "{'सक्रिय': चयनित}" एनजी-क्लिक = "चुने गए =! सिल्क्टेड" & gt; स्टफ़ 3 & lt; / li & gt; & Lt; / ul & gt;

मैं एक सूची आइटम को उपयोगकर्ता को चुनने के लिए एक क्लास को लागू करना चाहता हूं। केवल एक आइटम उस समय एक ही वर्ग हो सकता है इस दृष्टिकोण के लिए सबसे अच्छा कोणीय-इश तरीका क्या है? लगभग एक दर्जन तत्व हैं या तो, मैं प्रत्येक आइटम के लिए एक नया चर घोषित नहीं करना चाहता हूं।

< P> प्रत्येक आइटम के लिए एक संपत्ति सेट करें: 

  & lt; ul & gt; & Lt; li ng-class = "{'सक्रिय': चयनित == 1}" एनजी-क्लिक = "चयनित = 1" & gt; सामग्री 1 & lt; / li & gt; & Lt; li ng- वर्ग = "{'सक्रिय': चयनित == 2}" एनजी-क्लिक = "चयनित = 2" & gt; सामग्री 2 & lt; / li & gt; & Lt; li ng-class = "{'सक्रिय': चयनित == 3}" एनजी-क्लिक = "चयनित = 3" & gt; सामग्री 3 & lt; / li & gt; & Lt; / ul & gt;

I am trying to use the ASP.NET signal for the first time - here's what I did: created a new web Has been added to the project and the following signal R packages: I have created the following category: [Hub-name ("chat")] Public class ChatHub: Hub {Public Zero Halo () {Clients.All.hello ( ); }} and the following startup configuration: public partial class startup {public zero configuration (IAppBuilder app) {configure (app); App.MapSignalR (); }} However, whenever I navigate localhost: (port) / api / signalr / chat I get the following error: Protocol error: Unknown transport. I am running a new browser and trying different people so remove it from the API / URL, and just use the localhost: (potter) / signaller / Chat

Using KV lang on my Python code, I have taken a hard time trying to instantiate a dynamic class, the following Consider the code: My test.kv file looks like this: & lt; MyPopup @ popup: Title: 'Hello' size_hunt: (1, .6) Grid layout: ID: RouteGrid column: 2 padding: ['8dp', '4dp', '8dp', '4dp'] Difference: '8dp' label: text: 'some text here' button: text: 'OK' On_press: do_something () & lt; MyGrid & gt;: Rows: 1 Button: Text: 'Show Popup' on_press: root.pop.show () Then import Kivy.app into my test.py: I get the following error: raise Factory Exception ('Uncount Class' '% name) kivy.factory.FactoryException: Unknown class Can anyone tell me how to do this properly, what do I remember? If you need more information please let me know Thank you. Takes a call to the factory before the KV file is loaded, so you want the class to Are not yet in existence. As long as no clas...

python - mayavi mapping a discrete colorbar on a surface -

I want to change the color of the surface on the basis of another value (an ID) that is considered discrete (hence I In the simplified example given below, I have prepared a field with 3 different IDs: 0 / red on left 2 / blue 1 / green left But with the code below, I have some strange behavior on the border between red and blue (green Point) I think this is probably due to an interpolation! Code: import from import mlab np # np # my dataset -simplified-x, y, z = np.mgrid [-3: 3: 100] H, -3: 3: 100h, -3: 3: 100 h] value = NP. SQLT (x ** 2 + y ** 2 + z ** 2) # My color value: Volume is divided into 3 sub-versions taking colorvalues ​​with X = np.empty (values.shape) colorvalues [0:33,:,:] = 0 colorvalues ​​[33:66,:,:] = 2. Look [66:,:,:] = 1 src = mlab.pipeline.scalar_field (value) src.image_data.point_data.add_array (colorvalues.T.ravel ()) (1) .name = 'MyID' src.image_data. point_data.update src.image_data.point_data.get_array () # surface, contour = mlab.pipe...
