  • jQuery DOM element creation vs innerHTML

    - by Mohammad
    While having one of my questions answered, cletus mentioned that when creating elements in jQuery it's better to use direct DOM element creation, instead of innerHTML. I tried googling it but I wasn't able to find a good article with comparisons. I've provided this code bellow as an example and I was wondering if someone could help me rewrite it in direct DOM element creation form in hope that i would also learn the difference afterwards. var img = $(this); img.append('<p class="cap"><a href="'+img.parent().attr('href')+'">'+ img.attr('title')+'</p></a>'); Thanks so much.

  • Rendering PDFs from a database inside MVC views?

    - by Mohammad Sepahvand
    I was wondering if it's possible to do this without using 3rd party compnents in MVC 3. (I am open to free components though.) There are a couple of links out there but they seem to be mostly concerned with reporting and other code samples that do claim to do this sort of thing don't seem to compile. I'm not having any trouble saving and retrieving the PDFs to and from my database, but when I return the PDF as a File or a FileStreamResult the user is prompted with a download. A more desirable approach would be to actually render the PDFs inside the browser. I've had a look at iTextSHarp, it does the job to an extent, but it's not a complete solution. For example it will display the PDF inside the view if and only if the client has Adobe Reader installed, otherwise it prompts for a download. So technically, I'm mostly looking for a PDF viewer. Any ideas?

  • How to scroll the horizontal scrollbar in an iFrame from the parent frame?

    - by Mohammad
    Is there any cross browser way to scroll the horizontal scroll bar of an IFrame with super wide content with Javascript inside the parent frame. Also I need it to be attached to the mouse wheel event. This is what I have so far, it's a bit copy and paste at the moment and doesn't work unfortunately. //var myIframe = document.getElementById('iframeWithWideContent'); //myIframe.onload = function (myIframe) { var mouseWheelEvt = function (e){ var event = e || window.event; if (document.body.doScroll){ document.body.doScroll(event.wheelDelta>0?"left":"right"); }else if ((event.wheelDelta || event.detail) > 0){ document.body.scrollLeft -= 10; }else{ document.body.scrollLeft += 10; } return false; } if ("onmousewheel" in document.body){ document.body.onmousewheel = mouseWheelEvt; }else{ document.body.addEventListener("DOMMouseScroll", mouseWheelEvt); } //}? I probably should uncomment that code, replace document.body with myIframe though I wouldn't know what I'm doing wrong. Demo on JSBIN link fixed Any help from you JavaScript Lords would be very appreciated. Thank you!

  • Why build Javascript functions as JQuery plugins?

    - by Mohammad
    I've seen alot of JQuery implementations of existent JavaScript functions that merely wrap the JavaScript code in a JQuery wrapper and don't actually rely on any of JQuery's base for their operation. What are the benefits of using Javascript as a JQuery plugin? If there are none is there a speed loss to use a JQuery plugin that could have easily been implemented outside the wrapper just as well? Many thanks in advance (just trying to learn something here).

  • Alternative to before </body> tag inline Javascript

    - by Mohammad
    I know inline Javascript is frowned upon and with the new on-the-fly Javascript compressors that check for idle/unused function usage and omit the unused code, it seems good practice to have all your Javascript in an external file. My question is, in situations like FOUC (flash of unstyled content) which usually require little snippets of code right before the closing </body> tag, is there a JQuery resolution that would serve the same purpose, but from a remote Javascript file linked in the <head> of the document?

  • is jQuery 1.4.2 compatible with Closure Compiler?

    - by Mohammad
    According to the official release statement version 1.4 has been re-written to be compressed with Closure Compiler yet when I use the online version of closure compiler I get 130 warnings. This is the code I use. // ==ClosureCompiler== // @compilation_level ADVANCED_OPTIMIZATIONS // @output_file_name default.js // @code_url http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js // ==/ClosureCompiler== And as far as I know you get the real benefit of Closure Compiler if you include the library with your code also, so it removes the unused functions. Yet my testing show that I can't get any further than compressing the library itself.. What am I doing wrong? Any kind of insight will be much appreciated.

  • Forcing images to not wrap

    - by Mohammad
    I can't touch the html theme but I have access to the css files. <div class="photos"> <img src="a.jpg" alt="" align="left" /> <img src="b.jpg" alt="" align="left" /> <img src="c.jpg" alt="" align="left" /> //align makes the images wrap </div> Unfortunately I can't remove align="left" from the images otherwise this CSS snippet would have done the job .photos{ white-space: nowrap; } .photos img{ display: inline; vertical-align: top; } Any ideas? Is it even possible to make these images line-up horizontally without using the force of a table and only with CSS? Many Thank in advance!

  • Javascript code semantics

    - by Mohammad
    if(myVar = img.parent('a').length > 0){ var Y = 1; }else{ var Y = 2; } When I run this code myVar (being announced for the first time) takes the value of img.parent('a').length > 0 and becomes either false or true depending on the case. First Question: Is this a correct way of defining myVar? Second Question: Am I defining Y for the second time? Is my second 'var' excess? i.e. should i just write Y = 2;

  • Help with manipulating child/parent elements with jQuery

    - by Mohammad
    Currently I have this JQuery script var img = $(this); img.wrap('<div class="photo"></div>'); img.parent().append("<p>" + img.attr("alt") + "</p>"); which successfully turns the following: <img src="photo.jpg" alt="caption"> into this <div class="photo"> <img src="photos.jpg" alt="caption"/> <p>caption</p> </div> All is well unless the image has a link as a parent; <a href="#"><img since I want it to be correct html (I'm fussy) improving the resulting outcome bellow would be satisfactory <a href="#"> <div class="photo"> <img src="photos.jpg" alt="caption"/> <p>caption</p> </div> </a> to this: <div class="photo"> <a href="#"> <img src="photos.jpg" alt="caption"/> </a> <p><a href="#">caption</a></p> </div> </a> This is my jQuery script so far (which doesn't work bc I'm a noob) aha if(img.parent('a')){ var targetLink = img.parent('a').attr('href').val(); img.parent('a').wrap('<div class="photo"></div>'); img.parent('div').append('<p><a href="'+targetLink+'">' + img.attr("alt") + '</p></a>'); }else{ img.wrap('<div class="photo"></div>'); img.parent().append("<p>" + img.attr("alt") + "</p>"); }; Any advice, or help will be greatly appreciated : ) Thank You! Update *Answer* (works but looks sloppy) I'm editing it atm; if(img.parent('a').length){ var targetLink = img.parent().attr('href'); img.parent().wrap('<div class="photo"></div>'); var divTarget = img.parent('a').parent('div'); divTarget.append('<p><a href="'+targetLink+'">' + img.attr("alt") + '</p></a>'); }else{ img.wrap('<div class="photo"></div>'); img.parent().append("<p>" + img.attr("alt") + "</p>"); };

  • How to add dimensions to dynamic img elements (Updated)

    - by Mohammad
    I use a Json call to get a list of image addresses, then I add them individually to a div like this. Unfortunately the image dimension is not part of the Json information. <div id="container"> <img src="A.jpg" alt="" /> <img src="B.jpg" alt="" /> ... </div> Do any of you JQuery geniuses know of a code that would flawlessly and dynamically add the true Width and Height to each img element in the container as soon as each individual one is rendered? I was thinking maybe the code could do a image width check width > 0 to evaluate when the image has actually been rendered, then fire. But I wouldn't know how to go about that and make it work stably. How is the best way of going about this? Thank you so much! Update, As the answers point out, adding Width or Height to the elements is pretty routine. The problem here is actually writing a code that would know when to do that. And evaluate that condition for each image not the page as a whole.
