javascript - scrape parent page html from iframe -

-

i have iframe used generate pdf parent page. pdf maker (abcpdf) requires html file converts.

what @ present scrape parent's html using:

var temp; temp=parent.document.body.parentnode.innerhtml;

then use form in iframe submit server massaged remove things iframe sections before being saved temporary html file pdf maker.

however resulting html code mangled, <body> instead of <body> etc , quotes around ids removed etc.

is there better way grab html?

the reason don't regenerate page html parent page complex report. contains various controls allow user show/hide sections or sort rows in tables. html has reflect user customisations.

thanks

as david mentioned, using innerhtml, you're pretty @ browser's mercy. if want have control on serialization, walk dom of parent document yourself, appending string representation of nodes buffer. take longer , involve more code, result in full control on output.

something (pseudocode):

function serializeattributes(node, buffer) {   (attribute in node.attributes) {     buffer.append(' ' + attribute.name + '="' + attribute.value + '"');   } }  function serializechildren(node, buffer) {   (child in node.childnodes) {     if (child text node) {       buffer.append(child.value);     } else if (child element) {       // can add checks avoid going iframes, etc.       serializeelement(child, buffer);     }   } }  function serizalizeelement(node, buffer) {   buffer.append('<' + node.tagname);    serializeattributes(node, buffer);   if (node.haschildren) {     buffer.append('>');     serializechildren(node, buffer);     buffer.append('</' + node.tagname + '>');   } else {     buffer.append('\>');   } }  serializenode(window.parent.document);

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.
