javascript - Lazy Load for iframe is not working in IE7 - 


<style> .desgin_iframe_dimn { background: white; height: 500px; width: 500px; } </style> <iframe scrolling="no" id="lazy" class="desgin_iframe_dimn" data-src="http://www.google.com"></iframe> <p class="lazy">click here</p> <script> function lazyloadiframe() { $('.lazy').click(function() {     $('#lazy').attr('src', function() {         return $(this).data('src');     }); });  $('#lazy').attr('data-src', function() {     var src = $(this).attr('src');     $(this).removeattr('src');     return src; });  } lazyloadiframe(); </script>

demo here jsfiddle

above code works in other browsers in ie9 & ie8 not in ie7. how fix ?

i don't know why have part in code:

$('#lazy').attr('data-src', function() {     var src = $(this).attr('src');     $(this).removeattr('src');     return src; });

but since #lazy has no src, might part breaks on ie7. other browsers might work because piece of code executed before iframe declared in html.

i think want this:

html

here moved data-src clickable <p>:

<iframe scrolling="no" id="lazy" class="desgin_iframe_dimn"></iframe> <p class="lazy" data-src="http://www.wikipedia.com/">click here</p>

javascript

$(function() {     $('.lazy').click(function() {         $('#lazy').attr('src', $(this).data('src'));     }); });

where $(function() { }); executed on document load. don't call function in middle of html, consider use $(function() {});

i don't understand why did function() { return $(this).data('src') } while can $(this).data('src'), corrected too.

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
