html - jQuery input value switching -

-

i've been using code switch value of inputs onfocus , blur: 

$('input, textarea').focus(function() {             value=$(this).val();             $(this).attr("value","")};         });         $('input, textarea').blur(function() {             if($(this).val()=="") {                 $(this).val(value);             }         });

only problem is, when type these inputs, refocus after typing another, field goes blank. there way edit code inhibit this?

example here :)

i tried this, didn't have effect desire:

$('input, textarea').focus(function() {             value=$(this).val();     if($(this).val(value)) {             $(this).attr("value","");         });         $('input, textarea').blur(function() {             if($(this).val()=="") {                 $(this).val(value);             }         });

you need set initial value , check against that..

$('input, textarea').each(function(){     // initial storing of pre-defined value     $(this).data('initial', this.value); }).focus(function(){     var $this = $(this);     // on focus if value of field still initial clear     if ( (this.value) == $this.data('initial') )       this.value = ''; }).blur(function(){     var $this = $(this);     // on blur if value still cleared restore initial      if ( (this.value) == '' )         this.value = $this.data('initial'); })

update

you can avoid storing data, since there standard property named defaultvalue can use instead. (gets cleaner)

$('input, textarea').focus(function(){         // on focus if value of field still initial clear         if ( (this.value) == this.defaultvalue )           this.value = '';     }).blur(function(){         // on blur if value still cleared restore initial          if ( (this.value) == '' )             this.value = this.defaultvalue;     })

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....
