javascript - jQuery conflict when removing div after page load -

-
i'm trying remove div page (preferably prevent loading @ all) i'm settling on removing after page loads. when try following lines of code in jsfiddle , #content div gets removed, expected. <script type='text/javascript'>//<![cdata[ $(window).load(function(){ $('#content').remove(); });//]]> </script> however, have tried implementing on an actual website , in case, #content div isn't removed. any suggestions might wrong? if you're sharing jquery library uses dollar operation need guard against this, using anonymous wrapper: (function($) { $(window).on('load', function(){ $('#content').remove(); }); }(jquery)); note instead of .load() i'm using .on('load', fn). instead of on page load bind code on dom ready; jquery passes first argument inner function: jquery(function($) { $('#content').remove(); });

pug - html to jade error when contains <pre> -

-
i have static html documents, , want convert them jade. tried html2jade in npm, ok except this: <pre> elements in html convert empty, can me? the html code looks this: <pre><code>&lt;p&gt;hello&lt;/p&gt;&lt;span&gt;hello again&lt;/span&gt;</code></pre> the result is: pre. you can write couple different ways in jade. here 2 different methods. first takes advantage of jade's automatic escaping while second uses html entities instead. automatic escaping: pre code= '<p>hello</p><span>hello again</span>' html entities: pre code &lt;p&gt;hello&lt;/p&gt;&lt;span&gt;hello again&lt;/span&gt;

jvm - Limits and scope of the Java Attach API -

-
as far understand attach api introduced in java 6 allows inter-process modification of classes running in target jvm means of agents. questions are: is strategy limited instrumentation of classes have not been loaded yet target jvm ? , which limits of these transformations ?. example, body of existing methods can modified ?, or in class definition changed ? you can instrument both classes loaded or loaded intercepting them classfiletransformer . if retransformed method has active stack frames, active frames continue run bytecodes of original method. retransformed method used on new invokes. the redefinition/retransformation may change method bodies, constant pool , attributes. redefinition/retransformation must not add, remove or rename fields or methods, change signatures of methods, or change inheritance. these restrictions maybe lifted in future versions. class file bytes not checked, verified , installed until after transformations have been applied, if result

unit of timespan of command simin in matlab -

-
can guide me unit of parameter 'timespan' of simin command in matlab. [t,x,y1, y2, ..., yn] = sim(model,timespan,options,ut) i think can consider units choose, provided make other variables , parameters consistent choice. for example if modelling simple de like: d2x/dt^2 = ax + b dx/dt + c you may use "x" in meters , "t" in seconds, imply "a" given in sec^(-2), "b" in sec^(-1) , "c" in meters/second^2. but valid take "x" in km , "t" in years, provided gave constants a, b , c (and initial conditions) in appropriate units. in other words, it's not question of right or wrong units in dynamical system this, it's question of consistent or inconsistent units.

java - using keyword throws to declare throwing of Runtime Exceptions -

-
for me, these code static int faktorial (int n) throws arithmeticexception { if ((n < 0) || (n > 31)) { throw new arithmeticexception(); } if (n > 1) { return n * faktorial(n - 1); } else { return 1; } } and same code without throws arithmeticexception do same, when use following code: public static void main(string[] args) { try { int n; scanner sc = new scanner(system.in); system.out.print("insert integer number: "); n = sc.nextint(); system.out.println(n + "! = " + faktorial(n)); } catch (inputmismatchexception e) { system.out.println("not integer number!"); e. printstacktrace(); } catch (runtimeexception e) { system.out.println("number big!"); e. printstacktrace(); } } could describe me if use of throws arithmeticexception has advantages in code. i appreciate example of using keyword throws . thank much!
