Calling javascript functions from webview Android -


i have webview , loaded html file.

now want call javascript function datainput() webview.

here code.but console returns 

e/web console(435): uncaught referenceerror: datainput not defined:1

does know why? thanks!

webview engine = (webview) (findviewbyid(r.id.webview1));      engine.setwebviewclient(new webviewclient());     engine.setwebchromeclient(new webchromeclient() {           public boolean onconsolemessage(consolemessage cm) {                 log.d("myapplication", cm.message() + " -- line "                                      + cm.linenumber() + " of "                                      + cm.sourceid() );                 return true;               }             });     engine.getsettings().setjavascriptenabled(true);     engine.getsettings().setpluginsenabled(true);      engine.loadurl("file:///" + path);     engine.loadurl("javascript:datainput()");

my html files includes following code:

<script type="text/javascript">     function datainput( ) {      $( "video" ).each( function(e){this.play();}   );   $( "video" ).bind( "ended", function(e){this.play();}); } </script>

further edit:::::

i added button , calls js upon onclick , (kinda) worked... i.e.

public void onclick(view arg0) {     engine.loadurl("javascript:datainput()");  }

how come???? really want know why.....

p.s. said (kinda) work because video did autoplay (due $( "video" ).each( function(e){this.play();} );) not loop ($( "video" ).bind( "ended", function(e){this.play();}); <<< not working)

change javascript this

<script type="text/javascript" src="location_of_your_jquery_file" /> <script type="text/javascript"> $(document).ready(function () {     $.fn.gotofunc = function () {         $("video").each(function (e) {             this.play();         });         $("video").bind("ended", function (e) {             this.play();         });     };      function datainput() {         $.fn.gotofunc();     } }); </script>

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
