  56. # [02:43] <NarfZoid> I have an absolutely positioned element which seems to "cover up" some links that are next to it. But visually the links are in front, it's just the actual clickable area that is being covered up. Any ideas?
  57. # [02:43] * Joins: intellilogic (~intellilo@static-96-241-182-10.washdc.fios.verizon.net)
  58. # [02:43] <divya> well your abs pos element must be covering the text but not having a background
  59. # [02:43] <divya> so it appears like links are in front?
  60. # [02:45] <NarfZoid> Here's how it's set up:
  61. # [02:45] <NarfZoid> two images, facebook and twitter, are wrapped in anchor tags
  62. # [02:46] <NarfZoid> they are inside their own div called SocialLinks

  66. # [02:46] <NarfZoid> that is absolutely positioned

  75. # [02:52] <NarfZoid> But, the actual anchor tags get covered by the gradient div

  77. # [02:52] <NarfZoid> i know i could just abs position the social links too, but i want to avoid that
  78. # [02:53] <divya> NarfZoid: its most likely your images are inlined
  79. # [02:53] <divya> so the clickable area is not around the image only around the line-height.
  80. # [02:53] <divya> make the links inline-block and image itself block
  81. # [02:53] * Joins: joepie91 (~joepie91@86.93.142.233)
  82. # [02:54] <NarfZoid> divya: I tried that, setting them to inline-block so they would still be next to each other
  83. # [02:54] <divya> you could check the boundaries on the sociallinks div and see how it appears on Dragonfly or Chrome dev tools or firebug
  84. # [02:55] <divya> or you should paste your code in jsfiddle.net and reproduce it :)
  85. # [02:55] <NarfZoid> Okay, I'll check those out
  86. # [02:56] <NarfZoid> if I remove the gradient div the links work for the whole image

  99. # [03:26] <NarfZoid> I fixed it by changing some of the markup. took out the gradient div completely, added it to the footer, and then just used a negative margin value to overlap it behind the facebook/twitter links. Now they work :)

  414. # [13:34] <CapnKernel> I'm trying to understand it now...
  415. # [13:35] <Pomax> first we define the function name as a string, fn_Str
  416. # [13:35] <CapnKernel> Yep
  417. # [13:35] <Pomax> then we make an anonymous new function based on some string content, through the "sneaky" approach of making a Function that returns an object.
  418. # [13:36] <Pomax> that object has one property, our function string, with as value an actual function definition.
  419. # [13:36] <CapnKernel> I can see where myfunc is used (in the div's innerHtml) but I can't see where it's defined.
  420. # [13:36] * Quits: martndem_ (~martndemu@h254064.upc-h.chello.nl) (Ping timeout: 252 seconds)
  421. # [13:36] <Pomax> so when the function is run, it returns { <fn_str>: <new function that actually works}
  422. # [13:36] <CapnKernel> So the anonymous function returns a "myfunc" function?
  423. # [13:37] <Pomax> so the function's reference is functioncall()[fn_str], or, directly, functioncall().myfunc

  425. # [13:37] <Pomax> (since fn_str resolves to the string "myfunc")
  426. # [13:37] <Pomax> no, the anonymous function returns an object much like this:
  427. # [13:38] <Pomax> {a: function() { alert("lol"); }
  428. # [13:38] <Pomax> except 'a' is whatever fn_str is, and the function has, in this case, a more elaborate function

  432. # [13:40] <CapnKernel> Look up "a" in that array, and you'll get a function which can be evaluated by appending ().
  433. # [13:40] <Pomax> it's not an array

  438. # [13:41] <Pomax> which is a HUGE difference in this case

  441. # [13:41] <CapnKernel> So "a" is the name of an attribute of the object?
  442. # [13:41] <Pomax> correct
  443. # [13:42] <CapnKernel> With "function() { alert("lol");" being the value of that attribute.
  444. # [13:42] <CapnKernel> Oops, with "function() { alert("lol");}" being the value of that attribute.
  445. # [13:42] <Pomax> in order to make new Function() do what eval() normally does, but without using eval (thus making it a tiny bit safer, because it'll simply reject the entire code block if it has an error, rather than only the last erroring statement) we have to make it return something sensible
  446. # [13:42] <CapnKernel> Oops2: I nearly understood but now I don't, because your line {a: function() { alert("lol"); } has two x { but only one }
  447. # [13:43] <CapnKernel> I'm not trolling, I'm genuinely trying to understand.
  448. # [13:43] <Pomax> so concisely, this code says: var globalMoo = new Function("return { attribute: function(){} };")
  449. # [13:43] <CapnKernel> Should it be {a: function() { alert("lol"); }}

  459. # [13:46] <Pomax> we could do it the way I show it here, but in production I'd probably instead use something like this:
  460. # [13:46] <Pomax> var actualfunctionreference = ((new Function("return { "fn_str+":...}")())[fn_str];

  464. # [13:47] <CapnKernel> My myfunc() function may be many dozens of lines long.
  465. # [13:47] <Pomax> that is not a problem in the slightest, as long as you can stick it in a string.
  466. # [13:47] <CapnKernel> Is there any way I can keep it separate from the thingy which generates the reference?
  467. # [13:47] <CapnKernel> So the function has to be in the form of a string constant, rather than appearing in the source as a function?
  468. # [13:47] <Pomax> sure. Just have a var functionBody = "...."; functionBody += "...."; etc.
  469. # [13:48] <Pomax> not constant.
  470. # [13:48] <CapnKernel> It can't appear as a normal function?
  471. # [13:48] <Pomax> new Function simplyu takes a string as argument, representing the function body text
  472. # [13:48] <CapnKernel> I understand that, thank you.
  473. # [13:48] <Pomax> the problem with "a normal function" is that you already know what it looks like, and what all the code is, so normal functions and dynamic functions are mutually exclusive things.
  474. # [13:48] <CapnKernel> What if I want to keep myfunc as a function, and not start with a string?
  475. # [13:50] <Pomax> either you know what the code looks like, and you already wrote it in your source code (in which case we can do: window["function name"] = function(...) {...} and be done immediatley) or you don't, in which case it's an eval or new Function treatment
  476. # [13:50] <CapnKernel> As Ms2ger pointed out, if the function were outside the if, it would be trivial: window.myfunc
  477. # [13:50] <Pomax> if doesn't change the scope.
  478. # [13:50] <CapnKernel> Can I write window["function name"] = myfunc?
  479. # [13:50] <Pomax> if(a) { doThis = function(x,y) { return x+y; }}
  480. # [13:51] <Pomax> this will create a global property "doThis" that you can call as function
  481. # [13:51] <CapnKernel> Where myfunc is inside the scope of the if()? Will evaluating it later allow it to access the local vars inside the if, even though the function was located via window?

  747. # [18:31] <moo-_-> in fact, now the resizer gives a hit to UI thread because <canvas> operation always blocks
  748. # [18:32] <uf0_work> and i agree and disagree
  749. # [18:32] <Pomax> godaddy was punished, they fixed their policy, their reward is going "good boy, I won't leave until the next time you screw up"
  750. # [18:32] <djazz> <3 WebGL + Linux
  751. # [18:32] <Pomax> that said, pick whoever you like? I hear good things about heroku
  752. # [18:32] <djazz> its slower on windows
  753. # [18:32] <uf0_work> agree and disagree :)
  754. # [18:32] <Pomax> moo-_-, you can indeed, but the fact that canvas is subpixel makes it a chore to get right.
  755. # [18:33] <uf0_work> well the ones i'm looking at are... 1and1 and namecheap
  756. # [18:33] <moo-_-> Pomax: I managed to get accetable quality out of it for photos
  757. # [18:33] <moo-_-> when resizing photos to full HD quality
  758. # [18:35] <Pomax> those two things don't go together =P
  759. # [18:36] <Pomax> "full HD" is a video thing, and years behind the resolution digital photos are these days
  760. # [18:36] <moo-_-> yes
  761. # [18:36] <moo-_-> I refer to 1920 x 1020 resolution
  762. # [18:36] <moo-_-> as the target resolution for the downscale
  763. # [18:36] <Pomax> ah
  764. # [18:36] <moo-_-> because that's what user monitors are running
  765. # [18:36] * Pomax stabs HD
  766. # [18:37] <Pomax> nuts to that, I want my goddamn 16:10
  767. # [18:37] <Pomax> 16:9 is for chumps
  768. # [18:37] <moo-_-> mobile phones are 16:10?
  769. # [18:37] <moo-_-> smart phones, specifically
  770. # [18:38] <Pomax> no idea, to be honest. Not really the device I associate with even remotely needing "HD" resolutions or aspects
  771. # [18:38] <moo-_-> :)
  772. # [18:38] <Pomax> but let's see what my phone does
  773. # [18:38] <Pomax> oh right. or not. it can't see the wifi here.
  774. # [18:40] <Pomax> heh.
  775. # [18:40] <Pomax> in between 16:10 and 16:9
  776. # [18:40] <Pomax> (800x480)
  777. # [18:40] <Pomax> 16:9.6? =P
