Overriding CSS properties for iframe width

- by user2898989

I'm trying to put an iframe into a webpage, but no matter what I try to put in either the iframe properties or the custom CSS section of the website builder (or how many times I try to add !important to anything from width to right-margin), I can't get the iframe to extend rightward further than the page's preset width. Here's an example of the page and iframe that I'm working with: http://fmlcapitalinvestment.com/Search_Properties.html I need that script/iframe to be wide enough to show the search area. It seems pointless to copy and paste code and attributes I've tried setting, because nothing I do seems to have any effect, but just for showing how much I have no idea what I'm doing, here's my iframe code: <iframe id="idxFrame" style="padding:0; margin:0; padding-top: 0px; overflow-x:auto; width:1000px!important; border:0px solid transparent; background-color:transparent; max-width:none!important; right-margin:-200px!important" frameborder="0" scrolling="on" src="http://www.themls.com/IDXNET/Default.aspx?wid=8MSsp7Pf9eI55yjkDuB%2blX5awn7LnnVXh5PNYhq2ImAEQL" width="1200px" height="900px"></iframe> The "Website Builder" that I'm forced to use to make these kinds of pages is infuriating, but it does have a "Custom CSS" area where I can input additional CSS information. Is there something I could generically use to set iframes to their own widths?

Background-image is not displaying in Firefox

- by goa

Strange thing happens. Background-image is not displaying in Firefox under some versions of WindowsXP and Windows Vista, but displays in Firefox under Mac OSX. It also displays in IE. This is CSS: .cherry_banner { background: url("library/media/images/cherry_banner_top.png") no-repeat; width: 276px; display:block; min-height:100px; padding-top: 13px; color: #fdfdfd; margin-bottom:20px; } .cherry_banner a { color: #fdfdfd; } .cherry_banner a:hover { text-decoration:underline; } .cherry_banner li { list-style-type:none; } .cherry_banner h2 { font-size: 18px; margin-bottom: 10px; } .chb_text1 { background: url("library/media/images/cherry_banner_pixel.png") repeat-y; } .chb_text2 { background: url("library/media/images/cherry_banner_bottom.gif") bottom no-repeat; padding: 4px 14px 24px 25px; } And this is html: <div id="linkcat-8" class="cherry_banner tpt"><div class="chb_text1"><div class="chb_text2"> <h2>??? ?????????</h2> <ul class='xoxo blogroll'> <li><a href="http://inveda.ru/jyotish/naksatra-calendar/">???????? ?????????? ?????????????? ????????? ????????????? ??? ?? 2010?.</a></li> </ul> </div></div></div> You can see on http://www.inveda.ru - right column - red banner.

Determining unknown content-types with the Html5 file api

- by Jesse

I'm working through a small file upload script (learning experience) and I noticed that when selecting microsoft office related files (.doc or .docx for example) the file objects do not have a type specified: For .doc files I had expected the type to be "application/msword" and along the same train of thought .docx to be "application/vnd.openxmlformats-officedocument.wordprocessingml.document". In the cases when the type cannot be determined is the correct course of action to look at the file extension and match that to the "expected" content / mime type? Sample script: <div id="fileUpload"> <input type="file" id="fileElem" style="display:none;" onchange="handleFiles(this.files)"/> <a href="#" id="fileSelect">Select some files</a> </div> <script type="text/javascript"> var fileSelect = document.getElementById("fileSelect"), fileElem = document.getElementById("fileElem"); fileSelect.addEventListener("click", function (e) { if (fileElem) { fileElem.click(); } e.preventDefault(); }, false); function handleFiles(files) { console.log(files); } </script>

Questions about shifting from mysql to PDO

- by Scarface

Hey guys I have recently decided to switch all my current plain mysql queries performed with php mysql_query to PDO style queries to improve performance, portability and security. I just have some quick questions for any experts in this database interaction tool Will it prevent injection if all statements are prepared? (I noticed on php.net it wrote 'however, if other portions of the query are being built up with unescaped input, SQL injection is still possible' I was not exactly sure what this meant). Does this just mean that if all variables are run through a prepare function it is safe, and if some are directly inserted then it is not? Currently I have a connection at the top of my page and queries performed during the rest of the page. I took a look at PDO in more detail and noticed that there is a try and catch procedure for every query involving a connection and the closing of that connection. Is there a straightforward way to connecting and then reusing that connection without having to put everything in a try or constantly repeat the procedure by connecting, querying and closing? Can anyone briefly explain in layman's terms what purpose a set_exception_handler serves? I appreciate any advice from any more experienced individuals.

jQuery removeClass(), how it works

- by centro

I have images on my page. User can add more images onto the page by clicking a button. New images are added asynchronously. Initially, each image on page use a special class to be used when the image is loaded. After the image is loaded, that class is removed. Each image being loaded has the class imageLoading: <img class="imageLoading" scr="someimage.png"> After those images are loaded, I remove that class (simplified code without details): $('img.imageLoading') .each(function(){ $(this) .load(function(){ $(this) .removeClass('imageloading'); });}); Visually, I see that style is removed. But when I run the query again: $('img.imageLoading') I see via debugging that all images, not just loading ones, are returned, i.e. it works like I didn't remove the class for the images that were already loaded. I had a look into the page source, and I saw that actually in HTML the class was not removed, though removeClass() was called. Is that behavior by design that all visual changes are applied but the class attribute is not removed in HTML code? If so, how it can be workarounded in this case. Or, probably, I missed something.

Retrieving an element by array index in jQuery vs the each() function.

- by Alex Ciminian

I was writing a "pluginable" function when I noticed the following behavior (tested in FF 3.5.9 with Firebug 1.5.3). $.fn.computerMove = function () { var board = $(this); var emptySquares = board.find('div.clickable'); var randPosition = Math.floor(Math.random() * emptySquares.length); emptySquares.each(function (index) { if (index === randPosition) { // logs a jQuery object console.log($(this)); } }); target = emptySquares[randPosition]; // logs a non-jQuery object console.log(target); // throws error: attr() not a function for target board.placeMark({'position' : target.attr('id')}); } I noticed the problem when the script threw an error at target.attr('id') (attr not a function). When I checked the log, I noticed that the output (in Firebug) for target was: <div style="width: 97px; height: 97px;" class="square clickable" id="8"></div> If I output $(target), or $(this) from the each() function, I get a nice jQuery object: [ div#8.square ] Now here comes my question: why does this happen, considering that find() seems to return an array of jQuery objects? Why do I have to do $() to target all over again? [div#0.square, div#1.square, div#2.square, div#3.square, div#4.square, div#5.square, div#6.square, div#7.square, div#8.square] Just a curiosity :).

Initializing an object to all zeroes

- by dash-tom-bang

Oftentimes data structures' valid initialization is to set all members to zero. Even when programming in C++, one may need to interface with an external API for which this is the case. Is there any practical difference between: some_struct s; memset(s, 0, sizeof(s)); and simply some_struct s = { 0 }; Do folks find themselves using both, with a method for choosing which is more appropriate for a given application? For myself, as mostly a C++ programmer who doesn't use memset much, I'm never certain of the function signature so I find the second example is just easier to use in addition to being less typing, more compact, and maybe even more obvious since it says "this object is initialized to zero" right in the declaration rather than waiting for the next line of code and seeing, "oh, this object is zero initialized." When creating classes and structs in C++ I tend to use initialization lists; I'm curious about folks thoughts on the two "C style" initializations above rather than a comparison against what is available in C++ since I suspect many of us interface with C libraries even if we code mostly in C++ ourselves.

Use a table as container or not?

- by Camran

I have created my entire website by using a main table, and having the content inside the table. Some ppl suggest this is wrong, and I would like to know what to do specifically in my situation. On my index.html I have a <table align="center"> and then all content in it. Now the content is in form of DIVS and they all have relative positioning, so they are relative to the table. For example: <table align="center"> <tr> <td> <div style="position:relative; left:14px; top:50px;"> CONTENT HERE... (Form, divs, images) </div> </td> </tr> </table> I have just gotten to the stage of browser compatibility. Without making any changes whatsoever, my website works perfect in FF, SAFARI, Chrome and Opera. Only trouble with IE. So for my Q, if you where me, would you change my layout and remove the tables, and instead use alot more css and alot more DIVS, or would you go with what I have? And please if you answer me, don't just provide me with the answer, but also a "why" that is... in other words, give me arguments and facts... Thanks

for loop vs std::for_each with lambda

- by Andrey

Let's consider a template function written in C++11 which iterates over a container. Please exclude from consideration the range loop syntax because it is not yet supported by the compiler I'm working with. template <typename Container> void DoSomething(const Container& i_container) { // Option #1 for (auto it = std::begin(i_container); it != std::end(i_container); ++it) { // do something with *it } // Option #2 std::for_each(std::begin(i_container), std::end(i_container), [] (typename Container::const_reference element) { // do something with element }); } What are pros/cons of for loop vs std::for_each in terms of: a) performance? (I don't expect any difference) b) readability and maintainability? Here I see many disadvantages of for_each. It wouldn't accept a c-style array while the loop would. The declaration of the lambda formal parameter is so verbose, not possible to use auto there. It is not possible to break out of for_each. In pre- C++11 days arguments against for were a need of specifying the type for the iterator (doesn't hold any more) and an easy possibility of mistyping the loop condition (I've never done such mistake in 10 years). As a conclusion, my thoughts about for_each contradict the common opinion. What am I missing here?

how Two elements - IMG - DIV when hover over IMG show/hide the DIV - added with hover hide/show on i

- by Jan Fosgerau

Im very new to the wonder that is jquery. and i just figure out how to make my img buttons show/hide with a opacity difference (as such) <script type="text/javascript"> <![CDATA[ $(".ExcommKnap").mouseover(function () { $(this).stop().fadeTo('fast', 0.5, function(){}) }); $(".ExcommKnap").mouseout(function () { $(this).stop().fadeTo('fast', 1.0, function(){}) }); ]]> </script> which is good and all. but i also need to make the button when hovered over show text just above it that is specific to that button. i made these here elements that are looped in a for each. <div style="top:10px; width:755px;text-align:right; position:absolute; "> <div id="Page-{@id}" class="headlinebox"> <xsl:value-of select="@nodeName"/> </div> </div> <a href="{umbraco.library:NiceUrl(@id)}"> <img class="ExcommKnap" src="{$media/data[@alias='umbracoFile']}" /> </a> i need to make the individual text appear when hovered over its button. hence i have the id="page-{@id}" looped out along and need to get this place in the jquery code i presume. so when i hover over a img class="ExcommKnap" it makes the correct text visible. But i need the div id="page-{id}" to be invisible to begin with on pageload and then visible when its button is being hovered over. can anyone help ?

Drawing straight lines in JavaScript

need help speeding up tag cloud filter for IE

Hi All, Any ideas on how to speed this up in IE (performs decent in Firefox, but almost unusable in IE). Basically, it's a tag cloud with a filter text box to filter the cloud. <html> <head> <script type="text/javascript" src="jquery-1.3.2.min.js"></script> <script type="text/javascript"> $(document).ready(function(){ $('#tagFilter').keyup(function(e) { if (e.keyCode==8) { $('#cloudDiv > span').show(); } $('#cloudDiv > span').not('span:contains(' + $(this).val() + ')').hide(); }); }); </script> </head> <body> <input type="text" id="tagFilter" /> <div id="cloudDiv" style="height: 200px; width: 400px; overflow: auto;"> <script type="text/javascript"> for (i=0;i<=1300;i++) { document.write('<span><a href="#">Test ' + i + '</a> </span>'); } </script> </div> </body> </html> thanks, rodchar

jquery $.ajax load in UI dialog() problem

- by alex

i have a working bing Image search api with jsonp datatype. It's working with no problems. When i load the image search script in a Jquery UI dialog, it display properly and i'm able to search and see the results in the dialog() box. But if i close the dialog() and open it again, now if i search no results show. Looking at console.log, i do confirm the jason data is recieved, but for some reason it's not appending to the result div, so i see no result on the screen. This onyl happens if i close the dialog and open it again. If i refresh refresh the page and open the dialog again then search results are displayed. This is what i'm using to append the results. $.each(data.SearchResponse.Image.Results, function(i, item) { console.log(item.Thumbnail.Url); $("#Results").append("<li><img style='width:100px; height:75px;' src='" + item.Thumbnail.Url + "'/></li>"); });

SQL Server: Why use shorter VARCHAR(n) fields?

- by chryss

It is frequently advised to choose database field sizes to be as narrow as possible. I am wondering to what degree this applies to SQL Server 2005 VARCHAR columns: Storing 10-letter English words in a VARCHAR(255) field will not take up more storage than in a VARCHAR(10) field. Are there other reasons to restrict the size of VARCHAR fields to stick as closely as possible to the size of the data? I'm thinking of Performance: Is there an advantage to using a smaller n when selecting, filtering and sorting on the data? Memory, including on the application side (C++)? Style/validation: How important do you consider restricting colunm size to force non-sensical data imports to fail (such as 200-character surnames)? Anything else? Background: I help data integrators with the design of data flows into a database-backed system. They have to use an API that restricts their choice of data types. For character data, only VARCHAR(n) with n <= 255 is available; CHAR, NCHAR, NVARCHAR and TEXT are not. We're trying to lay down some "good practices" rules, and the question has come up if there is a real detriment to using VARCHAR(255) even for data where real maximum sizes will never exceed 30 bytes or so. Typical data volumes for one table are 1-10 Mio records with up to 150 attributes. Query performance (SELECT, with frequently extensive WHERE clauses) and application-side retrieval performance are paramount.

Page specific CSS or a single css file when developing a mobile (webkit) based site?

- by Mike

I am working on a mobile site for webkit browsers. I have been trying to find information on using multiple style sheets versus a single css file. There is a lot of information on this topic, but it not a lot of information pertaining to mobile browsers. My site will have a bunch of pages that while have page specific css. For a non-mobile site, it seems like generally people say that a single file will be faster, but that multiple files are easier to develop. However, on a mobile site is that still the case? If you put everything in one file, that will get cached after load, but that will make the first load slower. If you had page specific files, the first page would get loaded quicker, but every other page would then take a hit while making the page specific css http request. Does anyone have any thoughts on this? It sounds like they are saying one file is better as long as its under 1 MB (which my files def will)? http://www.yuiblog.com/blog/2010/07/12/mobile-browser-cache-limits-revisited/

Advance Query with Join

- by user1462589

I'm trying to convert a product table that contains all the detail of the product into separate tables in SQL. I've got everything done except for duplicated descriptor details. The problem I am having all the products have size/color/style/other that many other products contain. I want to only have one size or color descriptor for all the items and reuse the "ID" for all the product which I believe is a Parent key to the Product ID which is a ...Foreign Key. The only problem is that every descriptor would have multiple Foreign Keys assigned to it. So I was thinking on the fly just have it skip figuring out a Foreign Parent key for each descriptor and just check to see if that descriptor exist and if it does use its Key for the descriptor. Data Table PI Colo Sz OTHER 1 | Blue | 5 | Vintage 2 | Blue | 6 | Vintage 3 | Blac | 5 | Simple 4 | Blac | 6 | Simple =================================== Its destination table is this =================================== DI Description 1 | Blue 2 | Blac 3 | 5 4 | 6 6 | Vintage 7 | Simple ============================= Select Data.Table Unique.Data.Table.Colo Unique.Data.Table.Sz Unique.Data.Table.Other ======================================= Then the dual part of the questions after we create all the descriptors how to do a new query and assign the product ID to the descriptors. PI| DI 1 | 1 1 | 3 1 | 4 2 | 1 2 | 3 2 | 4 By figuring out how to do this I should be able to duplicate this pattern for all 300 + columns in the product. Some of these fields are 60+ characters large so its going to save a ton of space. Do I use a Array?

How to get an inner div to fill the entire wrapper div?

- by ripper234

I have the following html code: <div class="outer ui-draggable" style="position: relative;"> <div class="inner">Foo bar</div> </div> With this CSS: .outer { background-color: #F7F085; margin: 5px; height: 100px; width: 150px; text-align:center; vertical-align:text-bottom; } .outer .inner { display:inline; vertical-align:middle; height: 100px; width: 150px; } I would like the inner div to fill the outer div completely - the text block should be an entire 100X150 box. The problem is that this code doesn't produce the desired effect. The outer div is indeed the correct size, but the inner div seems to only fill a small area at the top of the outer div. I also tried using height:inherit and width:inherit instead of specifying a size.

Any point in subclassing UIButton to create a custom looking button?

- by glitch

I want to create a set of buttons that would work and feel very much like the Metro-style tiles that are available on Windows Phones. I would like to allow the user to tap them to access their underlying functionality (open a modal or something or that sort). I'm concerned that subclassing UIButton will not get me there. I need square corners and dynamic content inside the tiles themselves. The posts I've found around SO seem to suggest that subclassing a UIButton would not be a good idea for several reasons and that I should instead use UIView. That reply is from 2010, and I have no idea if in the 2+ years since then there have been considerable changes to how one would achieve that effect. Most users these days will have iOS 5.1+ if not 6.0 soon. Let's say I do go the UIView route. Should I implement UIResponder's touch events or should I instead go the UITapGestureRecognizer route? What's the better practice in 2012? Thank you!

Widget is a HTML/JS widget. I want run selectme by short code instead of repeating script in each widget. <div class="widget" id="widget1"> <div class="content"> [3][mystyle] </div> </div> <div class="widget" id="widget50"> <div class="content"> [4][yourstyle] </div> </div> ...........

Use jQuery.post() result in javascript function

I've got no clue how to do the following, so I wasn't sure what to search for either. For validating my registration form I've a javascript function that checkes the existence of the inserted username in the database onblur of the username textfield. function checkUsername(username){ $.post("checkmail.php", {mail: mailcheck} , function(data){ var $response=$(data); var response = $response.filter('#mail-response').text(); if(response == "taken") { document.getElementById('username').style.borderColor = rood; valid = false; } }); } This works fine, but now I want to validate it again onsubmit of the form in case users decide to submit an existing username. function validateForm() { var valid = true; //checks different fields //now check voor username existence var username = document.getElementById('username').value; checkUsername.call(username); if (!valid) { return false; } else { return true; } } I'm not familiar enough with Javascript to get this working. Probably thinking in the wrong direction...

Here is what the code looks like <form method="post" action="<?php echo ProjectTheme_post_new_with_pid_stuff_thg($pid, '1');?>"> <?php do_action('ProjectTheme_step1_before_title'); ?>  <li> <h2><?php echo __('Your Project Title', 'ProjectTheme'); ?>: <img src="../../images/help-icon.png" width="16" height="16" id="showhelp1"/></h2> <div id="help1">Your Project Title should be informative and brief.</div> <p><input type="text" style="width:90%;" class="do_input" name="project_title" value="Enter an informative & brief title..." onfocus="this.value = this.value=='Enter an informative & brief title...'?'':this.value;" onblur="this.value = this.value==''?'Enter an informative & brief title...':this.value;" /></p> <input type="submit" class="post-button" name="project_submit1" value="<?php _e("Next Step", 'ProjectTheme'); ?> »" /> </form> I am using a step by step form for users to fill in and I wanted to do a preview page, however I tried to use: if(isset($_POST['project_submit1'])){ $Name = $_POST['project_title']; echo "$Name"; } It shows up nothing.
