javascript - Execute stringByEvaluatingJavaScriptFromString before click event -

-

i using uiwebview in iphone , loaded 1 html page resources.

following html page code:

<html> <head> <title></title> <script language="javascript"> function callme(id) {        var input = 'input'+id;     document.getelementbyid(input).value = document.getelementbyid('code').value; } </script> </head> <body>  <input type=hidden id='code' name='code'> <a href="#" id="click1" name="click1" onclick='callme(1);'>click1</a> <input type="text" id="input1" name="input1"> </br> <a href="#" id="click2" name="click2" onclick='callme(2);'>click2</a> <input type=text id="input2" name="input2"> </br> <a href="#" id="click3" name="click3" onclick='callme(3);'>click3</a> <input type=text id=input3 name=input3>  </body> </html>

i have inject javascript on page using following code:

[webview stringbyevaluatingjavascriptfromstring:@"var field1 = document.getelementbyid('code'); field1.value='code010203';"];

what want when user click on link first injected script should run , onclick event's function(callme(1) or 2 or 3) link(click1,click2 or click3) should execute.

function callme(id) {        injectedcode();     var input = 'input'+id;     document.getelementbyid(input).value = document.getelementbyid('code').value; }

where injected code is:

[webview stringbyevaluatingjavascriptfromstring:@"var field1; function injectedcode() {field1 = document.getelementbyid('code'); field1.value='code010203';}"];

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,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
