Relative Path Problems in Javascript Ajax call -

-

okay, have javascript file following functions:

function askreason() {     var answer = prompt("please enter reason action:", "");     if (answer != null)         doreason(answer); }  function createxmlhttprequest() {     try {         return new xmlhttprequest();     }     catch (e)     { alert('xmlhttprequest not working'); }     try {         return new activexobject("msxml2.xmlhttp");     }     catch (e)     { alert('msxml2.xmlhtt not working'); }     try {         return new activexobject("microsoft.xmlhttp");     }     catch (e)     { alert('microsoft.xmlhttp not working'); }     alert("xmlhttprequest not supported");     return null; }  function doreason(reason) {     var xmlhttpreq = createxmlhttprequest();     var url = "/shared/askreason.ashx?reason=" + reason;     xmlhttpreq.open("get", url, true);     xmlhttpreq.send(null); }

this line:

    var url = "/shared/askreason.ashx?reason=" + reason;

is causing problem.

in vs 2010 debugging app - call works ashx handler.

when move project virtual directory - example http://localhost/myapp

this code break , have change javascript this:

var url = "http://localhost/myapp/shared/askreason.ashx?reason=" + reason;

any ideas on how can fix work in both environments or accept manual change when deploy apps servers?

thanks, mike

pointy's way works, have know in advance you're going deploy it.

alternately, don't start relative path /:

var url = "shared/askreason.ashx?reason=" + reason;

that resolved relative current document's location. if current document is:

http://localhost/myapp/index.aspx

...then resolve to

http://localhost/myapp/shared/askreason.ashx?reason=foo

Javascript line number mapping -

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

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.
