javascript - Selecting an element by class, then moving it -

-

i need select div it's classname.

after selecting it, need move 100 pixels.

here i've tried far:

html

<div  style="z-index:101;  position: absolute;  left: 0px; top: 300px; width: 20px; height:450px; padding: 0px; border: 0px;" class="wrapper" >content</div>

js

var class = document.getelementbyclassname("wrapper"); var div = class[0]; div.style.top = '100px';

not sure if i'm understanding nodelists correctly.

jsfiddle

1. missing s in getelementsbyclassname() ;

2. used class variable name, reserved word. name else.

3. move up, change .style.top property (300-100 = 200px).

fixed code:

var wrapper = document.getelementsbyclassname("wrapper");  var div = wrapper[0];  div.style.top = '200px';
<div  style="z-index:101;  position: absolute; left: 0px; top: 300px; width: 20px; height:450px; padding: 0px; border: 0px;" class="wrapper" >content</div>

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...
