javascript - Appending a preloaded image to a div -

-

So, I did not think it would be complicated, but I could not understand myself.

I use JSON with & lt; Head & gt; Load images already in . 

  // Images publish original = new image (698, 360); Original src = "imagenes_png / bosque_mapa.png"; ...

Then I want to add preloaded images with a DIV tag name test, as well as JS. 

 < // <

This is in my div tag body 

  & lt; Div id = "test" & gt; Testext & lt; / Div & gt;

Although this does not work div still testext

For people with the same problem:

Keep 

  Documents. GetElementById ('test'). AppendChild (original)

here 

  $ (document) .ready (function () {/ * code here * /}); $ (Document) .ready (function () {document.getElementById ('test'). AppendChild (original)});

Why? Read the comments of David Thomas and follow the post link!

** Note: This solution requires jQuery which can be loaded like this: 

  & lt ;! - LINK Zu JQUERY online - & gt; & Lt; Script src = "https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" & gt; & Lt; / Script & gt;

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?

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...
