  • Dynamically changing background color of specific text without changing other attributes

    - by gsingh2011
    I've written a chrome extension to find text on a page based on a regex query. When text is matched, I wrap the matched text in a <span> tag that has the class highlight where highlight only changes the background color to yellow. The issue is that sometimes there are already styles applied to <span> tags in a webpage. For example, the webpage might have this defined: span { font-size: 200%; } So when I insert my <span> tag in another <span> tag, the font-size is actually 400%. Is there an easy way for my code to just change certain properties of the text, like the background color, without applying the webpage's styles twice?

  • With a browser, how do I know which decimal separator does the client use?

    - by Quassnoi
    I'm developing a web application. I need to display some decimal data correctly so that it can be copied and pasted into a certain GUI application that is not under my control. The GUI application is locale sensitive and it accepts only the correct decimal separator which is set in the system. I can guess the decimal separator from Accept-Language and the guess will be correct in 95% cases, but sometimes it fails. Is there any way to do it on server side (preferably, so that I can collect statistics), or on client side? Update: The whole point of the task is doing it automatically. In fact, this webapp is a kind of online interface to a legacy GUI which helps to fill the forms correctly. The kind of users that use it mostly have no idea on what a decimal separator is. The Accept-Language solution is implemented and works, but I'd like to improve it. Update2: I need to retrive a very specific setting: decimal separator set in Control Panel / Regional and Language Options / Regional Options / Customize. I deal with four kinds of operating systems: Russian Windows with a comma as a DS (80%). English Windows with a period as a DS (15%). Russian Windows with a period as a DS to make poorly written English applications work (4%). English Windows with a comma as a DS to make poorly written Russian applications work (1%). All 100% of clients are in Russia and the legacy application deals with Russian goverment-issued forms, so asking for a country will yield 100% of Russian Federation, and GeoIP will yield 80% of Russian Federation and 20% of other, incorrect answers.

  • can't click on input element behind div element

    - by Preston
    On my site: http://alsite.com.br/solalev/ I have some elements on the bottom of page that I can't click through. Above the elements is a div called push.. I use this div to make the footer always stay on the bottom of my page even when the content is smaller... (I dont know if I do this right.. but it has worked).. So.. on Chrome and Firefox I can't click.. but on IE this works.... I use this: .push{ pointer-events: none; } but nothing happens...

  • Unobtrusive, self-hosted comments function to put onto existing web pages

    - by Pekka
    I am building a new site which will consist of a mix of dynamic and static pages. I would like to add commenting functionality to those pages with as little work as possible. I'm curious as to whether such a solution exists in PHP. The ideal set of features would be: Completely independent from the surrounding page / site: PHP code gets dropped into page, a page ID is added, done. Simple "write a comment" form Comments for each page are displayed using a PHP function Nice, clean output of <ul><li>.... that can be styled by the surrounding site Optional Captcha Optional Gravatar sensitivity Minimalistic administration area to moderate/delete comments, no ACL, can protect it using .htaccess The ideal integreation would be like this: <?php show_comments("my_page_name"); ?> this would 1. display a form to add a new comment that gets automatically associtated with my_page_name; and 2. display all comments that were made through this form using this ID. Does anybody know a solution like this? Bounty I am setting up a bounty because while there were some good suggestions, they all point to external services. I'm really curious to see whether there isn't anything self-hosted around. If this doesn't exist yet, it sure would be great to see as an Open Source project.

  • Hide table row based on content of table cell

    - by timkl
    I want to make some jQuery that shows some table rows and hides others based on the content of the first table cell in each row. When I click a list item I want jQuery to check if the first letter of the item matches the first letter in any table cell in my markup, if so the parent table row should be shown and other rows should be hidden. This is my markup: <ul> <li>A</li> <li>B</li> <li>G</li> </ul> <table> <tr> <td>Alpha1</td> <td>Some content</td> </tr> <tr> <td>Alpha2</td> <td>Some content</td> </tr> <tr> <td>Alpha3</td> <td>Some content</td> </tr> <tr> <td>Beta1</td> <td>Some content</td> </tr> <tr> <td>Beta2</td> <td>Some content</td> </tr> <tr> <td>Beta3</td> <td>Some content</td> </tr> <tr> <td>Gamma1</td> <td>Some content</td> </tr> <tr> <td>Gamma2</td> <td>Some content</td> </tr> <tr> <td>Gamma3</td> <td>Some content</td> </tr> </table> So if I press "A" this is what is rendered in the browser: <ul> <li>A</li> <li>B</li> <li>G</li> </ul> <table> <tr> <td>Alpha1</td> <td>Some content</td> </tr> <tr> <td>Alpha2</td> <td>Some content</td> </tr> <tr> <td>Alpha3</td> <td>Some content</td> </tr> </table> I'm really new to jQuery so any hint on how to go about a problem like this would be appreciated :)

  • Support both Standard mode and Quirks mode? Is that possible and necessary?

    - by tshao
    Today I was assigned a bug saying that some page elements don't work on IE8 Quirks mode at all, and I need to fix them. The point is that I believe our pages will always be rendered in Standard mode, because we specify DOCTYPE at the beginning of every page (via master page). I'd think it must be some debugging tools changed that during testing. I managed to convice QA to close it as by design, after a brief explanation to her. Now I start to think the question that whether we should have our page work on both Standard and Quirks mode. Maybe we should try to minimize the problem even if the page is not rendering in a supposed mode? Any standard or best practices on that? Thanks!

  • printing parent page and iframe contents from print button withing iframe.

    - by user329094
    I am using an iframe (I hate them by the way!) to call in a 3rd party checkout page into my parent page. The check out page doesn't allow me to pass any variables into it other than $total_amount. So, if an individual purchases 2 or more items they have no record of the items they purchase just the total amount. I have echoed the list of items purchased with php above the iframe for their reference. The final checkout step in the iframe allows you to print the receipt. However, it only prints the iframe content. Can you tell a print button within an iframe to print the parent page as well?

  • Sorting a list in PHP

    - by Andy
    Alright, so I've just (almost) finished my first little php script. Basically all it does is handling forms. It writes whatever the user put in to the fields of the form to a text file, then I include that text file in the index of the little page I have set up. So, currently it writes to the beginning of the text file (but doesn't overwrite previous data). But, several users wants this list to be alphabetically sorted instead. So what I want to do is make whatever they submit fall into the list in alphabetical order. The thing here is also that all I use in the text file are divs. The list is basically 'divided' into 3 parts. 'Title', 'Link', and 'Poster'. All I have done is positioned them with css. So, can I sort this list (the titles, in this case) alphabetically and still have the 'link' and 'poster' information assigned the way they already are, but just with the titles sorted? It don't use databases at all on my site, so there is no database handling at all used in this script (mainly because I'm not experienced at all in this).

  • disable text drag and drop

    - by maniek
    There is a common feature of modern browsers where a user can select some text and drag it to an input field. Within the same field it causes moving of text, between different fields it does copying. How do I disable that? If there is no portable way, I am mostly interested in firefox. This is an intranet webapp, so I am also interested in modifying the browser/getting a plugin to do this. Maybe some system-level settings (I`m on windows XP)? I need to keep the default select-copy-paste functionality. The background is I have multiple-field data entry forms, and users often drag something by mistake.

  • Remove border from IFrame

    - by JoelB
    How do I remove the border from an IFrame embedded in my web app? An example of the IFrame is: <IFRAME src="myURL" width=300" height="300">Browser not compatible. </IFRAME> I would like the transition from the content on my page to the contents of the IFrame to be seemless, assuming the background colors are consistent. The target browser is IE6 only and unfortunately solutions for others will not help.

  • I have a bunch of divs floated left, lined up in columns with different heights. They dont create a

    - by Roeland
    Hey guys, I am trying to create a grid like system with div's with content floated left. The problem is that the height of each div is not static since the content is different in each one. Since the height is different.. things get outta whack if one is taller then another in one row. Is there some sort of css way or js (prefer javascript) way to get around this. I really want to avoid setting large heights on the divs to get them to line up. You can see the example here: http://www.foreclosurejournalinc.com/index.php?option=com_hotproperty&view=type&id=1

  • Array data to display in table cells where col and row are given in array

  • POST a form in an iframe.

    - by Stavros Korokithakis
    I would like to POST a form in an iframe, generated like so: My JS loads an iframe inside the page, adds a form to the iframe and submits the form. What I would like to happen is the iframe to load the result of that request. So, I would effectively like to post a form and render the result inside the iframe, without touching the parent (apart from putting the iframe up for display in the first place). I am using the code from this answer: http://stackoverflow.com/questions/133925/javascript-post-request-like-a-form-submit/134003#134003 but I can't get it to not reload the parent. I post the form, and instead of the iframe refreshing, the entire parent refreshes. I don't know why that is, since the url it's posting to is different and would at least redirect there. Can anyone help me with this problem? I just want a post inside an iframe and only within the iframe, basically. EDIT: After some more research, apparently the form is not being created properly. I'm using document.createElement("form") and then document.getElementById("my_iframe_id").appendChild(form) to append it, but it does not seem to be working correctly.

  • Django/jQuery - read file and pass to browser as file download prompt

    - by danspants
    I've previously asked a question regarding passing files to the browser so a user receives a download prompt. However these files were really just strings creatd at the end of a function and it was simple to pass them to an iframe's src attribute for the desired effect. Now I have a more ambitious requirement, I need to pass pre existing files of any format to the browser. I have attempted this using the following code: def return_file(request): try: bob=open(urllib.unquote(request.POST["file"]),"rb") response=HttpResponse(content=bob,mimetype="application/x-unknown") response["Content-Disposition"] = "attachment; filename=nothing.xls" return HttpResponse(response) except: return HttpResponse(sys.exc_info()) With my original setup the following jQuery was sufficient to give the desired download prompt: jQuery('#download').attr("src","/return_file/"); However this won't work anymore as I need to pass POST values to the function. my attempt to rectify that is below, but instead of a download prompt I get the file displayed as text. jQuery.get("/return_file/",{"file":"c:/filename.xls"},function(data) { jQuery(thisButton).children("iframe").attr("src",data); }); Any ideas as to where I'm going wrong? Thanks!

  • How do I use price data in one table for a calculation that is stored in another table?

    - by shane
    I'm still leanring PHP/MySQL but have learned quite a bit thanks to codies on StackOverflow. I'm trying to setup a sort of room reservations system using two tables: SETUP: Room price table: Has, prices for a type room a client may want to rent as well as the dates (day of week) they wish to use it. Pricing varies based on day of the week and per room. I've setup a different table for each room type as each room type carries different pricing for each day of the week. So, There is an Alpha room table, Bravo room, etc. Within Alpha table are headers for the days of the week with pricing pre-entered into the rows. Client info table: Has the name, address, date of room use, etc data for the specific client. EXAMPLE: Alpha-room price table: Sun = $100; Mon = $200; Tue=$300 and so on. Bravo-room price table: Sun = $100; Mon = $200; Tue=$300 and so on. Client data table: ClientName; date-of-room-use; address; day_subtotal; grand_total. QUESTION: I'm trying to find PHP code that will: look at the date of room use in the client data table, look up the associated cost for that date in the specific room pricing table, record that unit cost in the day subtotal of the client data table and sum a grand total in the grand total row of the client data table (assuming the room may be used more than one day by the customer). I know there's something to do with join but I'm finding it difficult to grasp the concept and, if someone can demonstrate using this example, I think I will have a better understanding of how to work this sort of transaction. Thank you ALL in advance for your suggestions or alternatvie approaches.
