php - How to get the textarea ID using jQuery -

-

ive got textarea area on each table row unique id . how retrieve unique id javascript?

php:

$query = $db->query("select * bs_events eventdate = '".$date."'"); while($row = $query->fetch_array(mysqli_assoc)){   echo '<textarea id=\"att_name_" . $row['id'] . "\" style=\"width:300px\"></textarea>";' }

php output:

<textarea id="att_name_1" style="width:300px">   <textarea id="att_name_2" style="width:300px"> <textarea id="att_name_3" style="width:300px">

jquery:

$(document).ready(function(){      $("#book_event").submit(function(){        id = event.target.id.replace('att_name_','');        $.post("scripts/book_event.php", {              att_name: $("att_name_"+id).val(),        }, function(data){             if(data.success) {                $("#err").text(data.message).fadein("slow");             }        }, "json");     });    });

it looks me you're naming textareas correlate database entries, trying make updates , pass values back. assuming textareas in form you're submitting, can use:

$('#myform').submit(function(e){   // find each of text areas   $(this).find('textarea[id^=att_name]').each(function(i,e){     //     // here-in, e represents 1 of textareas     //      // submit update     $.post('scripts/book_event.php',{       att_name: $(e).val()     },function(data){       if (!data.success)         $("#err").text(data.message).fadein("slow");     },'json');   });   e.preventdefault(); });

ideally though, if you're looking use ajax push updates/changes server, may in .serialize() , push forms back. then, on server-side you'll standard $_post['att_name_1'] values can use actual updating. e.g.

// .serialize() example $('#myform').submit(function(e){   $.post('scripts/book_event.php',$(this).serialize(),function(data){     if (!data.success)       $("#err").text(data.message).fadein("slow");   });   e.preventdefault(); });

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....
