javascript - media queries image file name change on screen size -


I am using media queries on one site, but considering the download of a large file, I am taking only 3g games to download on an iPhone.

Is it possible to use jquery to change a file name (i.e. background-jpg to background- .phone / netbook / ipad maybe even using media queries.

< P> It seems that it should be possible in my head .. It would be great if anyone can work out of there: - D

thanks in advance

stu < / P>

I have found this code to find the screen size 

  $ (document) .r Eady (function () (if ((screen.width> = 1024) & amp; amp; amp; amp; (screen.height> = 768)) {Warning ('Screen size: 1024x600 or larger' ); $ ("Link [rel = stylesheet]: not (: first)"). Attr ({href: "detect1024.css"}) Other} {alerts ('Screen size: can be 1024x768, 800x600? '); $ ("Link [rel = stylesheet]: not (: first)"). Attr ({href: "detect800.css"}}}}};

and I got this script which I think is adding text to the file 

  $ ('rollover'). Hover (function () (/ when we use "roll on" var t = $ (This); T.attr ('src', t.attr ('src'), change the source of the input image. / ([[^.] *). (. *) /, "$ 1-over. $ 2") );}, Function () {var t = $ (this); T.attr ('src', t.attr ('src'). Mobile ',' ')); });

Any ideas how can I add two ??

Something like - 

  $ (document) .ready (function () {if ((screen.width> = 1024) & amp; amp; Screen.height> = 768)) {var t = $ (this); t.atter ('src', t.attr ('src') .replace ('- mobile', ''))});

but do not know how to fix syntax errors

Or maybe - still the syntax error has ended, however 

  $ (Document) .ready (function () {if ((screen.width> = 1024) & amp; amp; (screen> Height> 768)) {var re = new RegExp ("(. +) Back to the file namespace (again, "$ 1. $ 2")}}

This is possible, and is not difficult to obtain. But due to simplicity, why not use something Enter: 

  $ (document) .ready (function () (if ((screen.width = lt; = 960) & amp; amp; amp; amp; (.high & lt; = 640) ) $$ ("#added"). AddClass ("iphone");}};

In this way, when the browser is equal to or below 960x640 (iPhone 4 resolution) Detects a resolution, it will automatically add a range of "iphone" to any element you specify. This body can be tags, a custom ID and so on.

You only need to do that which specifies a different background image than the square "iPhone".

Simple.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
