javascript - Can a user permanently amend an HTML file through the browser? -


for example- user change actual code of html web browser using javascript prompt?

if had following code. 

<html> <head> <script>var person = prompt("please enter name");</script> </head> <body> <p>this should user amendable</p> <p>this shouldn't</p> </body> </html>

i don't mean store variable person temporarily, change html code , replace value of variable?

not such. alternatives include:

  • you take changes , send them server using xmlhttprequest. server respond storing them , sending new version requested in future.
  • you store changes in local storage / cookie / etc, , include javascript in page looks data , updates page loads.
  • a browser plugin written store modifications made given url.

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .
