How to getElementById() from HTML tag, that is rendered by embed javascript? -

-

i having file - index.html, has embed script.js.

script.js - rendering html <a href="url.html" id="url"> tag.

i want insert in index.html code, shows href value, rendered script.js:

var d = document.getelementbyid( 'url' ); alert(d.href);

but script working on tags, written index.html.

how script work?

index.html

<script type="text/javascript" src="script.js"></script> <script type="text/javascript"> var d = document.getelementbyid( 'url' ); alert(d.href); </script>

script.js:

document.write("<iframe src=iframe.html></iframe>");

iframe.html:

<a href=url.html id=url>test url</a>

--- edited ---

my friend came code:

<script type="text/javascript"> $(document).ready(function() { var href = $("iframe").contents().find("a").attr('href'); alert(href); }); </script>

but alert() showing - "undefined"

you have frame, document.getelementbyid() won't automatically access it. try this:

var frame = document.getelementsbytagname("iframe")[0];  frame.contentwindow.document.getelementbyid("url");

in first line, reference frame accessing first <iframe> element of page. there several other methods of doing so.

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
