How can I show a series of random images in a WordPress text widget using HTML/Javascript? -

-

i'm using wordpress 3.0.5 on dreamhost, trying create text widget in sidebar show random set of 9 (9) client logos. there total of 12 logos, located in /wp-content/clients folder, named logo1.jpg thru logo12.jpg.

the idea choose first image randomly, next 8 images in sequential order avoid duplicates.

update

got working, tips everyone!

here final, working version:

<div id="client-logos"></div>  <script type="text/javascript">  totallogos = 12;     firstpart = '<img src="/wp-content/clients/logo'; lastpart = '.jpg" height="50" width="110" />';  var r = math.ceil(math.random() * totallogos);  var content = document.getelementbyid('client-logos').innerhtml; document.getelementbyid('client-logos').innerhtml = firstpart + r + lastpart;  var t=0; (t=0;t<8;t++)    {       if (r == totallogos) { r=0; }       r++;       var content = document.getelementbyid('client-logos').innerhtml;       document.getelementbyid('client-logos').innerhtml = content + firstpart + r + lastpart;    }  </script>

document.write() runs before page finishes loading.. should use else..

first of all, should object of div container id:

your html:

    <div id="containerid"></div>  <script> var elem = document.getelementbyid('containerid'); elem.innerhtml= "firstpart + r + lastpart"; </script>

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
