javascript - Detecting drag position on an element -

-

i building wysiwyg editor build html emails. want able add row layouts editor drag , drop.

if row dragged , dropped above halfway point of drop target, want prepend row before drop target; , if dropped below halfway point, want append row after drop target.

is there way this?

you can use getboundingclientrect() coordinates of element while mouse button pressed , moving this

element.onclick = function() {     element.onmousemove = function() {         var x1 = element.getboundingclientrect().left,             x2 = x1 + element.getboundingclientrect().width,             y1 = element.getboundingclientrect().top,             y2 = element.getboundingclientrect().height;     } }

and can whatever these coordinates.

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...
