css - displaying part of an image with jquery -


i doing visualization, , calculations can return fractions (e.g. 23.43, 4.3, 39.79,...). need show icons every integer in result (e.g. 23 -> 23 icons, 4--> 4 icons, 39 --> 39 icons).

now should break icons of fraction part, maybe in decimals, possibly down quarters. e.g. 23.43 --> 23 icons , 0.4 (or 0.5 if quarters) of horizontal part of icon, 4.3 --> 4 icons , 0.3 (or 0.25) of x part of icon, 39.79 --> 39 icons , 0.8 (or 0.75) of x part of icon, , on.

how this? saw approaches using backgrounds css, doesn't need. i'd prefer jquery way of doing it.

edit: here image of trying do

enter image description here

i set image background-image of <div>, , set width multiple of image's width (eg. 23.4 * width) , background-repeat repeat-x.

if refuse usage of background, set overflow hidden , use loop in js document.createelement specified number of images inside div. way, last 1 can 'half-visible' overflow.

edit:

in order solve this, need set line break. example, seeing image 21px wide, let's maximum number of images in 1 line 20 (840px wide).

let's then, need place 75.5 images.

first, create div width of 840px , put 75.5 - (75.5 % 20) images there. should create 3 rows of images. put rest (75.5 % 20 = 15.5 => 16 images) in new div width of 15.5 * 21 px , overflow hidden in previous case. again, last 16th image half visible.

edit 2:

if width of images varies, there can new technique: use 1 div fixed width like. put images it. add new div after last image opaque background in colour of pages's:

html:

<div id="wrapper">     <div id="overlay"> </div>

css:

#wrapper {      background: blue;     width: 700px; } #overlay {     background: blue;     display: inline-block;     position: relative;  }

js:

var count = 75.5,     ceil = math.ceil(count),     image = 'http://jsfiddle.net/img/logo.png',     overlay = $('#overlay'),     wrapper = $('#wrapper'),     hide = ceil - count;  for(var = 0; < ceil; i++) {     var img = document.createelement('img');     img.src = image;     wrapper.prepend(img); }  overlay.css({     'width': img.clientwidth,     'left': -img.clientwidth * hide,     'height': img.clientheight, });

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 ...
