• What is the compatible JQuery line of code for IE7 and IE8?

  - by user144842

  This line of code is working fine for Firefox $("#<%=txt1.ClientID%>").text() but not for IE8 and IE7. See the scenario below in order to understand what I really mean:- Scenario:- Loading .aspx page. populating text box with some data from database. Now user changes data in same text-box at client-side (means page not yet submitted) So here in firefox, the above line of javascript is showing me the actual data came from database, but IE7&8 showing me the changed data. But I want actual data. So i need some compatible code for IE7 & IE8 I hope i explained it well what i need. Thanks in advance

• Preventing user from inserting *

  - by user990635

  I'm trying to prevent user from inserting * in a textbox. This is what I was trying to do, but here it only detects * if this is the only inserted character. For example texts like: *, etc. When allowed characters are mixed with *, then it cannot detect it. For example inputs such as: *hjh, etc.. and maybe how to make it replace only * with "" and not the whole field? <script type="text/javascript"> function testField(field) { var regExpr = new RegExp("[^*]"); if(!regExpr.test(field.value)) { field.value = ""; } } </script> <input type="text" id="searchGamesKeyword" class="searchGamesTextBox" name="searchGamesKeyword" onblur="testField(this);" />

• How to search and validate plain texts (where it starts with http AND ends with .aspx) to be a valid hyperlink in a page body content?

  - by syntaxcode

  My web page content is populated by a plain text that is retrieved from a CDATA format - plain text data. This is the site http://checksite.apsx to get information. For more information, visit http://moresites.com/FAQ/index.html or search the site. Now, my goal is to convert this plain text to a valid hyperlinks. I've used a javascript code that does the conversion - /((http|https|ftp):\/\/[^ ]+)/g; , but sometimes if there are multiple words, it captures an invalid URL. My question: Is there a way to strictly capture any string that starts with "http" AND ends with ".html" or "aspx" will be converted into a valid hyperlink? it should look like this - This is the site http://checksite.apsx to get information. For more information, visit http://moresites.com/FAQ/index.html or search the site.

  I have an external javascript file that I want to, upon include, write some HTML to the end of the web page. Upon doing so though I get the error Missing } in XML expression on the line that uses dropdownhtml. Here is my code var dropdownhtml = '<div id="dropdown"></div>'; $(document).ready(function(){ //$(document).append(dropdownhtml); alert(dropdownhtml); }); Doing either append or alert throws up the same error, what is going wrong?

• Use of .apply() with 'new' operator. Is this possible?

  - by Premasagar

  In JavaScript, I want to create an object instance (via the new operator), but pass an arbitrary number of arguments to the constructor. Is this possible? What I want to do is something like this (but the code below does not work): function Something(){ // init stuff } function createSomething(){ return new Something.apply(null, arguments); } var s = createSomething(a,b,c); // 's' is an instance of Something The Answer From the responses here, it became clear that there's no in-built way to call .apply() with the new operator. However, people suggested a number of really interesting solutions to the problem. My preferred solution was this one from Matthew Crumley (I've modified it to pass the arguments property): var createSomething = (function() { function F(args) { return Something.apply(this, args); } F.prototype = Something.prototype; return function() { return new F(arguments); } })();

• Does .live() binding work for jQuery in IE7?

  - by Steve

  Hi everyone, I have a piece of javascript which is supposed to latch onto a form which gets introduced via XHR. It looks something like: $(document).ready(function() { $('#myform').live('submit', function() { $(foo).appendTo('#myform'); $(this).ajaxSubmit(function() { alert("HelloWorld"); }); return false; }); }); This happens to work in FF3, but not in IE7. Any idea what the problem is?

I have this: <div id="test"> hello world </div> I want to grab the text "hello world" and display it somewhere else on the website as well.

• How Do I Reference An Element By Name With [] Brackets In It?

  - by user384030

  How do you reference a element in jquery BY NAME that has the [] in it. <select name="values[]" multiple="true"> <option value="1">1</option> <option value="2">2</option> <option value="2">2</option> </select> <script type="text/javascript"> $('[name=values[]]'); </script> this should grab the element, but it does not work, I believe the [] in the name is messing it up, escaping it doesn't seem to work either. I can't figure out what I'm doing wrong

Something like val()?

• How do I install a language pack in Windows 7 Home Premium?

  - by ekaj

  Specifically, I want Korean (link), but I hope this helps other people in general. According to this page, it is only possible for Ultimate and Enterprise. Specifically, I'd like to enable my keyboard to type in Korean, and I specified Korean as the input language (Start - type "Input Languages", only result). Under the General tab, I selected Add, and specified Korean.. but it doesn't work, because the language pack isn't installed I presume. Would anyone know how to add different language input / packs to Windows 7 Home Premium? Also, I tried following this tutorial on adding a language pack to HP, but the .cab keeps disappearing so it will not work. Note: Unlike the link in the tutorial as well, I do not have an option to change the display language of Windows, only the option to change input methods.

• Height of a html window's content (not just the viewport height)

  - by gatapia

  Hi All, I'm trying to get the height of a html window's content. This is the full height of the content not the visible height. I have had some (very limited) success using: document.getElementsByTagName('html')[0].offsetHeight in FireFox. This however fails in IEs and it fails in Chrome when using absolute positioned elements (http://code.google.com/p/chromium/issues/detail?id=38999). A sample html file that can be used to reproduce this is: <html> <head> <style> div { border:solid 1px red; height:2000px; width:400px; } .broken { position:absolute; top:0; left:0; } .fixed { position:relative; top:0; left:0; } </style> <script language='javascript'> window.onload = function () { document.getElementById('window.height').innerHTML = window.innerHeight; document.getElementById('window.screen.height').innerHTML = window.screen.height; document.getElementById('document.html.height').innerHTML = document.getElementsByTagName('html')[0].offsetHeight; } </script> </head> <body> <div class='fixed'> window.height: <span id='window.height'>&nbsp;</span> <br/> window.screen.height: <span id='window.screen.height'></span> <br/> document.html.height: <span id='document.html.height'></span> <br/> </div> </body> </html> Thanks All Guido Tapia

• Does anyone have database, programming language/framework suggestions for a GUI point of sale system

  - by Jason Down

  Our company has a point of sale system with many extras, such as ordering and receiving functionality, sales and order history etc. Our main issue is that the system was not designed properly from the ground up, so it takes too long to make fixes and handle requests from our customers. Also, the current technology we are using (Progress database, Progress 4GL for the language) incurs quite a bit of licensing expenses on our customers due to mutli-user license fees for database connections etc. After a lot of discussion it is looking like we will probably start over from scratch (while maintaining the current product at least for the time being). We are looking for a couple of things: Create the system with a nice GUI front end (it is currently CHUI and the application was not built in a way that allows us to redesign the front end... no layering or separation of business logic and gui...shudder). Create the system with the ability to modularize different functionality so the product doesn't have to include all features. This would keep the cost down for our current customers that want basic functionality and a lower price tag. The bells and whistles would be available for those that would want them. Use proper design patterns to make the product easy to add or change any part at any time (i.e. change the database or change the front end without needing to rewrite the application or most of it). This is a problem today because the Progress 4GL code is directly compiled against the database. Small changes in the database requires lots of code recompiling. Our new system will be Linux based, with a possibility of a client application providing functionality from one or more windows boxes. So what I'm looking for is any suggestions on which database and/or framework or programming language(s) someone might recommend for this sort of product. Anyone that has experience in this field might be able to point us in the right direction or even have some ideas of what to avoid. We have considered .NET and SQL Express (we don't need an enterprise level DB), but that would limit us to windows (as far as I know anyway). I have heard of Mono for writing .NET code in a Linux environment, but I don't know much about it yet. We've also considered a Java and MySql based implementation. To summarize we are looking to do the following: Keep licensing costs down on the technology we will use to develop the product (Oracle, yikes! MySQL, nice.) Deliver a solution that is easily maintainable and supportable. A solution that has a component capable of running on "old" hardware through a CHUI front end. (some of our customers have 40+ terminals which would be a ton of cash in order to convert over to a PC). Suggestions would be appreciated. Thanks [UPDATE] I should note that we are currently performing a total cost analysis. This question is intended to give us a couple of "educated" options to look into to include in or analysis. Anyone who could share experiences/suggestions about client/server setups would be appreciated (not just those who have experience with point of sale systems... that would just be a bonus).

• Character Encoding: â??

  - by akaphenom

  I am trying to piece together the mysterious string of characters â?? I am seeing quite a bit of in our database - I am fairly sure this is a result of conversion between character encodings, but I am not completely positive. The users are able to enter text (or cut and paste) into a Ext-Js rich text editor. The data is posted to a severlet which persists it to the database, and when I view it in the database i see those strange characters... is there any way to decode these back to their original meaning, if I was able to discover the correct encoding - or is there a loss of bits or bytes that has occured through the conversion process? Users are cutting and pasting from multiple versions of MS Word and PDF. Does the encoding follow where the user copied from? Thank you website is UTF-8 We are using ms sql server 2005; SELECT serverproperty('Collation') -- Server default collation. Latin1_General_CI_AS SELECT databasepropertyex('xxxx', 'Collation') -- Database default SQL_Latin1_General_CP1_CI_AS and the column: Column_name Type Computed Length Prec Scale Nullable TrimTrailingBlanks FixedLenNullInSource Collation text varchar no -1 yes no yes SQL_Latin1_General_CP1_CI_AS The non-Unicode equivalents of the nchar, nvarchar, and ntext data types in SQL Server 2000 are listed below. When Unicode data is inserted into one of these non-Unicode data type columns through a command string (otherwise known as a "language event"), SQL Server converts the data to the data type using the code page associated with the collation of the column. When a character cannot be represented on a code page, it is replaced by a question mark (?), indicating the data has been lost. Appearance of unexpected characters or question marks in your data indicates your data has been converted from Unicode to non-Unicode at some layer, and this conversion resulted in lost characters. So this may be the root cause of the problem... and not an easy one to solve on our end.

• Why do people have to use multiple versions of jQuery in the same page?

  - by reprogrammer

  I have noticed that sometimes people have to use multiple versions of jQuery in the same page (See question 1 and question 2). I assume people have to carry old versions of jQuery because some pieces of their code is based on an older version of jQuery. Obviously, this approach causes inefficiency. The ideal solution is to refactor the old code to use the newer jQuery API. I wonder if there are tools that automate the process of upgrading a piece of code to use a newer version of jQuery. I've never written programs in in either Javascript or jQuery. So, I'd like to hear from programmers experienced in these language about their opinion on this issue. In particular, I'd like to know the following. How much of problem it is to have to load multiple versions of jQuery? Have you ever had to load multiple versions of any other library in the same page? Do you know of any refactoring tools that helps you migrate your code to use the updated API? Do you think such a refactoring tool is useful? Are you willing to use it?

• Dashcode code translation

  - by Alex Mcp

  Hi, a quick, probably easy question whose answer is probably "best practice" I'm following a tutorial for a custom-template mobile Safari webapp, and to change views around this code is used: function btnSave_ClickHandler(event) { var views = document.getElementById('stackLayout'); var front = document.getElementById('mainScreen'); if (views && views.object && front) { views.object.setCurrentView(front, true); } } My question is just about the if conditional statement. What is this triplet saying, and why do each of those things need to be verified before the view can be changed? Does views.object just test to see if the views variable responds to the object method? Why is this important? EDIT - This is/was the main point of this question, and it regards not Javascript as a language and how if loops work, but rather WHY these 3 things specifically need to be checked: Under what scenarios might views and front not exist? I don't typically write my code so redundantly. If the name of my MySQL table isn't changing, I'll just say UPDATE 'mytable' WHERE... instead of the much more verbose (and in my view, redundant) $mytable = "TheSQLTableName"; if ($mytable == an actual table && $mytable exists && entries can be updated){ UPDATE $mytable; } Whereas if the table's name (or in the JS example, the view's names) ARE NOT "hard coded" but are instead a user input or otherwise mutable, I might right my code as the DashCode example has it. So tell me, can these values "go wrong" anyhow? Thanks!

• Is it possible for onunload confirm to open a new url in the same window?

  - by Dan Peschio

  Hi - this is my first post and I'm a JS novice, so please forgive my ignorance... Heres my question, its in two parts: 1.) At onunload I want an alert that asks the user if they would like to go to a related URL. The code I'm using works, but it open the URL in a new window and this can be blocked by a pop-up blocker even though the user has opted-in. Is there a way to have it open in the same window and negate the pop-up blocker? 2.) is there a way to take the onunload function out of the body tag and put it the script? Heres the code I'm using: <script language=javascript> function confirmit() { var closeit= confirm("Before you go would you like to add your press kit to the Search Press Kits database?"); if (closeit == true) {window.open("http://NEWURLHERE.com");} else {window.close();} } </script> </head> <body onunload="confirmit();"> peace </body> Thanks in advance, Dan

• Remove "Flash" between pages while using Internet Explorer modal boxes

  - by AaronS

  I have an internal web application, that is IE specific, and uses a lot of IE specific modal boxes: (window.showModalDialog). I recently received a request to remove the "flash" when navigating between pages of the site. To accomplish this, I just added a meta transition tag to my master page: <meta http-equiv="Page-Enter" content="blendTrans(duration=0.0)" /> This works perfectly except for the modal boxes. When you launch a modal box, and then move it around, the web page behind it keeps a trail of the modal box instead of re-drawing the web page content. This prevents the user from moving the modal box to read anything that was behind it. Is there a way to prevent the "flash" between pages in an IE specific site and have the site still work with modal boxes? Please note, this is a large and complex site, so re-architecting it to not use modal boxes isn't an option. This is an asp.net, c# web application, and all of my users are using IE 7 and IE 8 if it makes any difference. -Edit- To duplicate this, put the following into an html page, and open it in Internet Explorer: <html> <head> <title>Test</title> <meta content="blendTrans(duration=0.0)" http-equiv="Page-Exit"> </head> <body> <script language="javascript"> window.showModalDialog('modal.htm', window); </script> </body> </html>

  hey guys, this might be really stupid, but hopefully someone can help. I'm trying to post to an external script using ajax so i can mail the data, but for some reason my data is not making it to the script. $(document).ready(function() { $("#submitContactForm").click(function () { $('#loading').append('<img src="http://www.xxxxxxxx.com/demo/copyshop/images/loading.gif" alt="Currently Loading" id="loadingComment" />'); var name = $('#name').val(); var email = $('#email').val(); var comment = $('#comment').val(); var dataString = 'name='+ name + '&email=' + email + '&comment=' + comment; $.ajax({ url: 'http://www.xxxxx.com/demo/copyshop/php/sendmail.php', type: 'POST', data: '?name=Dave&[email protected]&comment=hiiii', success: function(result) { $('#loading').append('success'); } }); return false; }); }); the php script is simple (for now - just wanted to make sure it worked) <?php $name = $_POST['name']; $email = $_POST['email']; $comment = $_POST['comment']; $to = '[email protected]'; $subject = 'New Contact Inquiry'; $message = $comment; mail($to, $subject, $message); ?> the jquery is embedded in an .aspx page (a language i'm not familiar with) but is posting to a php script. i'm receiving emails properly but there is no data inside. am i missing something? i tried to bypass the variables in this example, but its still not working thanks
