javascript - "onclick" of a button in a popup works only once -


i have html/php webpage (the file called searchresults.php) imports jquery mobile. when enter page, url 

www.domain.com/searchresults.php?&sort="off"&max="5"

in example sorting off , 5 items displayed. on page button opens popup want user able change these settings. use built-in jquery mobile popup. on popup can toggle "sort" on/off , can enter new maximum. on popup "ok" button confirm new settings. looks this:

<a href="" id="okbutton" data-role="button" onclick="sortagain();">ok</a>

the sortagain(); function in javascript looks this:

function sortagain(); {     //some code necessary variables//     ...      //change href of button reload page     document.getelementbyid("okbutton").href = "searchresults.php" + "?keyword=" + var1 + "&sort=" + var2 + "&max=" + var3  }

so, basically, right before "ok" button navigates page, set href of page should navigate too.

this scheme works, , searchresults.php file fetched again server , re-interpreted (with new variables in url).

however, if try change settings again after changing once, popup nothing! in other words, href of ok button on popup stays empty , javascript function sortagain() not called. don't understand why calls onclick method fine first time, refuses call again?

i assume has fact popup html code integral part of searchresult.php file, , hrefing same page gives problems? popup pure html, no php involved in popup code. , again, works fine first time.

you should check out how attach events via javascript. see here: javascript attaching events

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 ...
