    I am capturing image using canvas and i want to store a captured image in MySQL Database using Javascript. This is my code: <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, maximum-scale=1.0"> <style> body {width: 100%;} canvas {display: none;} </style> <title>Instant Camera - Remote</title> <script> var video, canvas, msg; var load = function () { video = document.getElementById('video'); canvas = document.getElementById('canvas'); msg = document.getElementById('error'); if( navigator.getUserMedia ) { video.onclick = function () { var context = canvas.getContext("2d"); context.drawImage(video, 0, 0, 240, 320); var image1 = canvas.toDataURL("image/png"); document.write('<img src="' + image1 + '" />'); }; } else { msg.innerHTML = "Native web camera not supported :("; } }; window.addEventListener('DOMContentLoaded', load, false); </script> </head> <body> <video id="video" width="240" height="320" autoplay> </video> <p id="error">Click on the video to send a snapshot to the receiving screen</p> <canvas id="canvas" width="240" height="320"> </canvas> </body> </html>

  • Javascript BBcode function not working

    - by Dave
    I have a string I want to convert to divs but it doesn't close the div properly. The example string i am using is this: [quote]Quote by: user1 [quote]Quote by: user2 ads[/quote]Test[/quote]Testing 2. This results in: <div class="quote" style="margin-left:10px;margin-top:10px;"> Quote by: user1 [quote]Quote by: user2 ads </div> Test[/quote]Testing 2. But it will not convert the internal quotes properly. My Javascript function is like this: function bbcode_parser(str) { search = new Array( /\[b\](.*?)\[\/b\]/g, /\[i\](.*?)\[\/i\]/g, /\[quote](.*?)\[\/quote\]/g, /\[\*\]\s?(.*?)\n/g); replace = new Array( "<strong>$1</strong>", "<em>$1</em>", "<div class='quote' style='margin-left:10px;margin-top:10px;'>$1</div>"); for (i = 0; i < search.length; i++) { str = str.replace(search[i], replace[i]); } return str; } I have provided a JSFiddle for you to see it in action: http://jsfiddle.net/gRaFW/2/ Please help :)

  • Using Javascript to get URL Vars, not working when multiple values present in QueryString

    - by bateman_ap
    Hi, I am using a Javascript function to get the values of a URL to pass to jQuery using the function below: function getUrlVars() { var vars = [], hash; var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&'); for(var i = 0; i < hashes.length; i++) { hash = hashes[i].split('='); vars.push(hash[0]); vars[hash[0]] = hash[1]; } return vars; } And then setting the value like this: var type = getUrlVars()["type"] This all works perfectly, however I have just come into a situation where I need to get multiple values, one of my form elements are checkboxes where multiple values can be checked, so my URL will look something like this: http://www.domain.com/test.php?type=1&cuisine[]=23&cuisine[]=43&name=test If I alert out the cuisine value using the function above I only ever get the final value: alert (getUrlVars()["cuisine[]"]); Would alert "43". What I would like it to be is a comma delimited string of all "cuisine" values. ie in the above example "23,43" Any help very welcome! In case any solution requires it I am using PHP 5.3 and Jquery 1.4

  • include ::before pseudo class in javascript

    - by user1955837
    Why is this thing not working? If I remove ::before from javascript and css it works. But due to the design needs there has to be a ::before. How do I point to the class + ::before? $(function () { var sections = $("section"); var navigation_links = $("nav a"); sections.waypoint({ handler: function (event, direction) { var active_section; active_section = $(this); if (direction === "up") active_section = active_section.prev(); var active_link = $('nav a[href="#' + active_section.attr("id") + '"]'); navigation_links.removeClass("selected::before"); active_link.addClass("selected::before"); }, offset: '25%' }) }); css: .selected::before { display: block; content: ""; margin-top: 6px; width: 8px; height: 8px; background: url(../img/sprite.png) -126px -196px; background-size: 400px 480px; float: left; margin-left: 20px; margin-right: 20px; }

  • Javascript dynamic table memory usage

    - by Dan
    I use a dynamic table: <html> <body> <button id="button">Build table</button> <div id="container"> <script type="text/javascript"> window.onload=function(){ var table = null; var row = "<tr><td>111111111111111111111111111111111111111111111111111111</td>" + "<td>222222222222222222222222222222222222222222222222222222</td>" + "<td>333333333333333333333333333333333333333333333333333333</td></tr>"; var data = null; for (var i = 0; i < 2000; i++){ data += row; } var obj = document.getElementById("button"); obj.onclick=function buildTable(){ document.getElementById("container").innerHTML = "<div><table><tbody>" + data + "</tbody></table></div>"; }; }; </script> </body> </html> Using chromes task manager, each time new data is loaded the memory usage increases considerably and doesn't go down, so after some time the app consumes a lot of memory and requires the browser to be closed. Is there any change in the code I can use to solve this or is it a browser side problem?

    - by user3718986
    Question is, It takes me 3 hours to fly from NY to CA. How much it will take me if I fly directly from NY to Florida. suppose that distance from CA to Flordia is 8 hours by air..Rule is if you suppose to travel from NY to Florida you will have to pass through CA. I did the quesiton in JavaScript below but coding isn't correct. Can someone fixed this issue for me please? var destination = prompt('Please enter your destinations. We are currently flying to NY,CA and FL'); var locatioon = prompt("specify your current location. "); switch (destination) { case 'NY': { distanceTeller(locatioon); break; } break; case 'CA': { distanceTeller(locatioon); break; } break; case 'FL': { alert("11 HR"); } default: alert('dont look at me'); break; } function distanceTeller(locatioon) { if (locatioon == 'CA') { alert('it will take you 3 hours'); } else if (locatioon == 'FL') { alert('it will take you 8 hours'); } else alert('it will take you 11 hours to reach NY'); }

  • Can reducing index length in Javascript associative array save memory

    - by d777
    I am trying to build a large Associative Array in JavaScript (22,000 elements). Do I need to worry about the length of the indices with regards to memory usage? In other words, which of the following options saves memory? or are they the same in memory consumption? Option 1: var student = new Array(); for (i=0; i<22000; i++) student[i] = { "studentName": token[0], "studentMarks": token[1], "studentDOB": token[2] }; Option 2: var student = new Array(); for (i=0; i<22000; i++) student[i] = { "n": token[0], "m": token[1], "d": token[2] }; I tried to test this on Google Chrome DevTools, but the numbers are inconsistent to make a decision. My best guess is that because the Array indices repeat, the browser can optimize memory usage by not repeating them for each student[i], but that is just a guess. Thanks.

  • Textbox time validations (javascript)

    - by unos
    I have a textbox in which user can enter time (eg- 01:00) and also a drop down box for entering AM/PM fields. (Since the AM/PM field is used, 12-hour time format is used.) The text box allows a max entry of 5 chars only (eg - 01:00). Pls let me know how I can set the 3rd char as a default -colon : , so that the user simply has to enter only the time. How to check if the time entered by the user is numeric or not?. Autocompletion feature : for eg, if user enters 1 then it would automatically be set to 01:00 Javascript Validations for 12-hour format. Eg: if user enters 13:00 then it should change to 01:00 How can I append the text box time values with the am/pm value selected in the drop down box?. Once the values are appended, automatically populate another text box (text box 2) with the result. Eg: 01:00 + pm should be set as 01:00p in the new text box (text box 2). Any help would be appreciated.

  • SQL SERVER – Introduction to FIRST _VALUE and LAST_VALUE – Analytic Functions Introduced in SQL Server 2012

    - by pinaldave
    SQL Server 2012 introduces new analytical functions FIRST_VALUE() and LAST_VALUE(). This function returns first and last value from the list. It will be very difficult to explain this in words so I’d like to attempt to explain its function through a brief example. Instead of creating a new table, I will be using the AdventureWorks sample database as most developers use that for experiment purposes. Now let’s have fun following query: USE AdventureWorks GO SELECT s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty, FIRST_VALUE(SalesOrderDetailID) OVER (ORDER BY SalesOrderDetailID) FstValue, LAST_VALUE(SalesOrderDetailID) OVER (ORDER BY SalesOrderDetailID) LstValue FROM Sales.SalesOrderDetail s WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty GO The above query will give us the following result: What’s the most interesting thing here is that as we go from row 1 to row 10, the value of the FIRST_VALUE() remains the same but the value of the LAST_VALUE is increasing. The reason behind this is that as we progress in every line – considering that line and all the other lines before it, the last value will be of the row where we are currently looking at. To fully understand this statement, see the following figure: This may be useful in some cases; but not always. However, when we use the same thing with PARTITION BY, the same query starts showing the result which can be easily used in analytical algorithms and needs. Let us have fun through the following query: Let us fun following query. USE AdventureWorks GO SELECT s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty, FIRST_VALUE(SalesOrderDetailID) OVER (PARTITION BY SalesOrderID ORDER BY SalesOrderDetailID) FstValue, LAST_VALUE(SalesOrderDetailID) OVER (PARTITION BY SalesOrderID ORDER BY SalesOrderDetailID) LstValue FROM Sales.SalesOrderDetail s WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty GO The above query will give us the following result: Let us understand how PARTITION BY windows the resultset. I have used PARTITION BY SalesOrderID in my query. This will create small windows of the resultset from the original resultset and will follow the logic or FIRST_VALUE and LAST_VALUE in this resultset. Well, this is just an introduction to these functions. In the future blog posts we will go deeper to discuss the usage of these two functions. By the way, these functions can be applied over VARCHAR fields as well and are not limited to the numeric field only.

  • ODI 11g - Cleaning control characters and User Functions

    - by David Allan
    In ODI user functions have a poor name really, they should be user expressions - a way of wrapping common expressions that you may wish to reuse many times - across many different technologies is an added bonus. To illustrate look at the problem of how to remove control characters from text. Users ask these types of questions over all technologies - Microsoft SQL Server, Oracle, DB2 and for many years - how do I clean a string, how do I tokenize a string and so on. After some searching around you will find a few ways of doing this, in Oracle there is a convenient way of using the TRANSLATE and REPLACE functions. So you can convert some text using the following SQL; replace( translate('This is my string'||chr(9)||' which has a control character', chr(3)||chr(4)||chr(5)||chr(9), chr(3) ), chr(3), '' ) If you had many columns to perform this kind of transformation on, in the Oracle database the natural solution you'd go to would be to code this as a PLSQL function since you don't want the code splattered everywhere. Someone tells you that there is another control character that needs added equals a maintenance headache. Coding it as a PLSQL function will incur a context switch between SQL and PLSQL which could prove costly. In ODI user functions let you capture this expression text and reference it many times across your mappings. This will protect the expression from being copy-pasted by developers and make maintenance much simpler - change the expression definition in one place. Firstly define a name and a syntax for the user function, I am calling it UF_STRIP_BAD_CHARACTERS and it has one parameter an input string;  We then can define an implementation for each technology we will use it, I will define Oracle's using the inputString parameter and the TRANSLATE and REPLACE functions with whatever control characters I want to replace; I can then use this inside mapping expressions in ODI, below I am cleaning the ENAME column - a fabricated example but you get the gist.  Note when I use the user function the function name remains in the text of the mapping, the actual expression is not substituted until I generate the scenario. If you generate the scenario and export the scenario you can have a peak at the code that is processed in the runtime - below you can see a snippet of my export scenario;  That's all for now, hopefully a useful snippet of info.

  • [JavaScript-CSS-Firefox] Cannot change borderColor of TD

    - by Tadeus Prastowo
    Using JS to set the background color of a TD is fine. But, setting the border color is problematic in FF 3.0.18 although IE 6 doesn't experience this. FF is problematic in that it requires the TD element to have an attribute style initialized to border-style: solid. Without that, setting border color of a TD won't work. Is this known bug? How do I set the border color without having to set style attribute as well as the initialization value? I know another trick of setting the class attribute instead of setting the border color directly. Is this an indication that somehow TD hates having its border color set dynamically? Is this known as well? The problematic code is below (the goal is find out why setting the border color of simple truth 1 does not work while simple truth 3 works when I employ the trick described above): <html> <head> <title>Quirks FF 3.0.18</title> <style type="text/css"> table { border-collapse: collapse; } </style> <script type="text/javascript"> function changeBgColor() { document.getElementById('simple').style.backgroundColor='yellow'; document.getElementById('simple2').style.backgroundColor='yellow'; document.getElementById('simple3').style.backgroundColor='yellow'; } function quirk(id) { var x = document.getElementById(id); x.style.border = '2px solid red'; } </script> </head> <body> <input type="button" onclick="changeBgColor()" value="Change background color"/> <input type="button" onclick="quirk('simple')" value="Change border color 1"/> <input type="button" onclick="quirk('simple2')" value="Change border color 2"/> <input type="button" onclick="quirk('simple3')" value="Change border color 3"/> <table> <tr><td id="simple">Simple truth 1</td></tr> </table> <table> <tr><td><span id="simple2">Simple truth 2</span></td></tr> <table> <tr><td id="simple3" style="border-style: solid">Simple truth 3</td></tr> </table> </body> </html>

  • Determine the 'Overtype' mode using Javascript

    - by Snorkpete
    We are creating a web app to replace an old-school green-screen application. In the green-screen app, as the user presses the Insert key to switch between overtype and insert modes, the cursor changes to indicate which input mode the user is currently in. In IE (which is the official browser of the company), overtype mode also works, but there's no visual indication as to whether overtype mode is on or not, until the user starts typing and possibly over-writes existing information unexpectedly. I'd like to put some sort of visual indicator on the screen if in overtype mode. How can you determine if the browser is in 'overtype mode' from Javascript? Is there some property or function i can query to determine if the browser is in overtype mode? Even an IE-specific solution would be helpful, since our corporate policy dictates the browser to use as IE7 (pure torture, btw). (I do know that one solution is to do check for key presses of the Insert key. However, it's a solution that I'd prefer to avoid since that method seems a bit flaky & error-prone because I can't guarantee what mode the user would be in BEFORE he/she hits my page. ) The reasoning behind this question: The functionality of this portion of the green-screen app is such that the user can select from a list of 'preformatted bodies of text'. crude eg. The excess for this policy is: $xxxxxx and max limit is:$xxxxxx Date of policy is: xx/xx/xxxx and expires : xx/xx/xxxx Some other irrelevant text After selecting this 'preformatted text', the user would then use overtype to replace the x's with actual values, without disturbing the alignment of the rest of the text. (To be clear, they can still edit any part of the 'preformatted text' if they so wished. It's just that usually, they just wish to replace specific portions of the text. Keeping the alignment is important since these sections of text can end up on printed documents.) Of course, the same effect can be achieved by just selecting the x's to replace first, but it would be helpful (with respect to easing the transition to the web app) to allow old methods of doing things to continue to work, while still allowing 'web methods' to be used by the more tech-savvy users. Essentially, we're trying to make the initial transition from the green-screen app to the web app be as seemless as possible to minimise the resistance from the long-time green-screeners.

I'll occasionally get 'copyArray is not defined' even in this example: function copyArray( pa ) { var la = []; for (var i=0; i < pa.length; i++) la.push( pa[i] ); return la; } Function.prototype.bind = function( po ) { var __method = this; var __args = []; // sometimes errors -- in practice I inline the function as a workaround __args = copyArray( arguments ); return function() { /* bind logic omitted for brevity */ } } As you can see, copyArray is defined right there, so this can't be about the order in which script files load. I've been getting this in situations that are harder to work around, where the calling function is located in another file that should be loaded after the called function. But this was the simplest case I could present, and appears to be the same problem. It doesn't happen 100% of the time, so I do suspect some kind of load-timing-related problem. But I have no idea what. @Hojou: That's part of the problem. The function in which I'm now getting this error is itself my addLoadEvent, which is basically a standard version of the common library function. @James: I understand that, and there is no syntax error in the function. When that is the case, the syntax error is reported as well. In this case, I am getting only the 'not defined' error. @David: The script in this case resides in an external file that is referenced using the normal <script src="file.js"></script> method in the page's head section. @Douglas: Interesting idea, but if this were the case, how could we ever call a user-defined function with confidence? In any event, I tried this and it didn't work. @sk: This technique has been tested across browsers and is basically copied from the prototype library.

  • Extracting the source code of a facebook page with JavaScript

    - by Hafizi Vilie
    If I write code in the JavaScript console of Chrome, I can retrieve the whole HTML source code by entering: var a = document.body.InnerHTML; alert(a); For fb_dtsg on Facebook, I can easily extract it by writing: var fb_dtsg = document.getElementsByName('fb_dtsg')[0].value; Now, I am trying to extract the code "h=AfJSxEzzdTSrz-pS" from the Facebook Page. The h value is especially useful for Facebook reporting. How can I get the h value for reporting? I don't know what the h value is; the h value is totally different when you communicate with different users. Without that h correct value, you can not report. Actually, the h value is AfXXXXXXXXXXX (11 character values after 'Af'), that is what I know. Do you have any ideas for getting the value or any function to generate on Facebook page. The Facebook Source snippet is below, you can view source on facebook profile, and search h=Af, you will get the value: <code class="hidden_elem" id="ukftg4w44"> <!-- <div class="mtm mlm"> ... .... <span class="itemLabel fsm">Unfriend...</span></a></li> <li class="uiMenuItem" data-label="Report/Block..."> <a class="itemAnchor" role="menuitem" tabindex="-1" href="/ajax/report/social.php?content_type=0&amp;cid=1352686914&amp;rid=1352686914&amp;ref=http%3A%2F%2Fwww.facebook.com%2 F%3Fq&amp;h=AfjSxEzzdTSrz-pS&amp;from_gear=timeline" rel="dialog"> <span class="itemLabel fsm">Report/Block...</span></a></li></ul></div> ... .... </div> --> </code> Please guide me. How can extract the value exactly? I tried with following code, but the comment block prevent me to extract the code. How can extract the value which is inside comment block? var a = document.getElementsByClassName('hidden_elem')[3].innerHTML;alert(a);
