events - Removing two children and its parent with Javascript -

-

been struggling 1 have following dom structure:

<ol id="add_images">     <li>         <input type="file" /><input type="button" name="removebutton" />     </li>      <li>        <input type="file" /><input type="button" name="removebutton" />     </li>      <li>         <input type="file" /><input type="button" name="removebutton" />     </li>

basically i'm trying remove children , containing parent (the li tag) when clicking remove button.

i have tried every manner of parentnode , removechild combinations. below javascript, can children not parent. 

function addfile(addfilebutton) {     var form = document.getelementbyid('add_images');     var li = form.appendchild(document.createelement("li"));      //add additional input fields should user want upload additional images.         var f = li.appendchild(document.createelement("input"));     f.classname="input";     f.type="file";     f.name="files[]";      //add remove field button should user change mind     var rb = li.appendchild(document.createelement("input"));     rb.type="button";     rb.value="remove file";     rb.onclick = function () {//this problem         li.removechild(this.parentnode);         li.removechild(this);     } }

i'm sure simple. help.

since you're trying remove <li>, need parentnode, ol.

li.parentnode.removechild(this.parentnode);

you use form variable reference ol.

form.removechild(this.parentnode);

or:

form.removechild(li);

or without variables in order avoid creating closure.

this.parentnode.parentnode.removechild(this.parentnode);

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.
