javascript - If td has value "No" add class to different td -


i have following code:

<td class="bedrag">     #_att{factuur bedrag} </td> <td class="paid">     #_att{betaald}{ja|nee} </td>

in td paid option can given yes or no. change background of bedrag depending on chosen in td paid. figured best way go addclass using javascript. googled around while , found piece of code:

jquery('a:contains("sponsored")').closest('.post-item').addclass('sponz');

i changed fit needs:

$('.paid:contains("nee")').closest('.bedrag').addclass('sponz');

but didn't work. tried following code:

$('.paid:contains("nee")').addclass('sponz');

this adds class sponz td paid. want add bedrag. tried this:

('.bedrag:has(.paid:contains("nee"))').addclass('sponz');

but didn't work.

anyone know how code working add sponz the td bedrag when user selects option nee? in advance!

closest() isn't quite need looks parents. .bedrag sibling of .paid, need use prev() instead:

$('.paid:contains("nee")').prev('.bedrag').addclass('sponz');
.sponz { color: #c00; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <table>    <tr>      <td class="bedrag">bedrag 1</td>      <td class="paid">nee</td>    </tr>    <tr>      <td class="bedrag">bedrag 2</td>      <td class="paid">ja</td>    </tr>    <tr>      <td class="bedrag">bedrag 3</td>      <td class="paid">nee</td>    </tr>  </table>

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
