javascript - Animating window scrolling -

-

hi using following method programmatically scroll web document:

window.scrollby(0, delta)

the current implementation of scrollby jumps document new position. there way of animating this? using webkit specifically, , jquery (or other javascript framework) not option.

thanks in advance.

you can animate invoking interval:

setinterval(function() {     window.scrollby(0, 5); }, 13);

this of course on , over, need put in conditional check, when cancel interval. like:

var timerid = setinterval(function() {     window.scrollby(0, 5);      if( window.pageyoffset >= 500 )         clearinterval(timerid); }, 13);

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
