  • javascript. is it posible for one member of an object to access another member of that object withou

    - by joox
    For example: var myObj={ myValue="hola", asMember=function(){ alert( this.myValue ); } }; myObj.asMember(); // will work fine var asGlobal=myObj.asMember; // global alias for that member function asGlobal(); // won't work in javascript (will work in AS3, but i need js now) So the question is, can I rewrite asMember so that it could be called by global alias and without mentioning myObj at all? It's understood that if I define it: asMember=function(){ alert( myObj.myValue ); } it will work, but in my case, mentioning myObj is not acceptable even inside the function itself (because myObj may be reassigned later, but asGlobal won't change and should keep working)

  • How do I write escape characters verbatim (without escaping) in C# using StreamWriter?

    - by Joel
    I'm writing a utility that takes in a .resx file and creates a javascript object containing properties for all the name/value pairs in the .resx file. This is all well and good, until one of the values in the .resx is This dealer accepts electronic orders. /r/nClick to order {0} from this dealer. I'm adding the name/value pairs to the js object like this: streamWriter.Write(string.Format("\n{0} : \"{1}\"", kvp.Key, kvp.Value)); When kvp.Value = "This dealer accepts electronic orders./r/nClick to order {0} from this dealer." This causes StreamWriter.Write() to actually place a newline in between 'orders.' and 'Click', which naturally screws up my javascript output. I've tried different things with @ and without using string.Format, but I've had no luck. Any suggestions?

  • How to force HtmlUnit to save page?

    - by booroondook
    Hello. I'm using HtmlUnit to click on a HtmlElement that triggers Javascript action: currentPage = ((HtmlElement) currentPage.getByXPath("//*[contains(@onclick, 'check();')]").get(0)).click(); The element is: <a href="#" onclick="check(); return false;"> The page returned is quite similar to the page, containing that element: same URL, mostly same HTML, but there are some minor differences in the HTML and HtmlUnit doesn't save the new page. I'm using HttpAnalyzer to sniff the traffic and I see that the Webclient correctly handles JS and send the right request. The response is also correct, but when I dump the contents of the currentPage to a file, I see that the actual page didn't change. How can I fix it?

  • How do I use Mercurial?

    - by Derek
    I'm assuming Mercurial is for having an updated website and it archiving the old stuff? Easy to test things and such? My question is, how exactly should I get started and can somebody give me a crash course in using Mercurial and using the following techs below: Notepad++ for coding FTP PHP/MySQL Jquery & other js libraries I use windows and would like to keep things fairly simple. I'm developing 1 website currently and want some kind of CVS system in place. Or should I just stick to my current edit file in notepad++ and upload via ftp method and make a backup copy of everything every once and a while? Any thoughts? EDIT: I'm doing http://bugtracker.gttools.com/public/wiki/bluehost/Mercurial right now in order to try and 'install' it.

  • Microsoft JScript runtime error: Object required

    - by Nani
    I wrote a simple javascript function for validating to fields in a aspx page function validate() { if (document.getElementById("<%=tbName.ClientID%>").value=="") { alert("Name Feild can not be blank"); document.getElementById("<%=tbName.ClientID%>").focus(); return false; } if (document.getElementById("<%=ddlBranch.ClientID%>").value=="SelectBranch") { alert("Branch Should Be Selected"); document.getElementById("<%=ddlBranch.ClientID%>").focus(); return false; } } Everything worked fine. Later I linked it to aspx page like a external js file. Now its giving error "Microsoft JScript runtime error: Object required". I'm unable to know where I went wrong.

  • how to run javascript from .NET code ?

    - by dotnetcoder
    I have a webrequest that returns a html response which has form inside with hidden fields with some javascript that submits the form automatically on pageload ( if this was run in a browser). If I save this file as *.html and run this file in browser , the java script code automatically posts the form and the output is excel file. I want to be able to generate this file(excel) from a c# code which is not running in broswer. I tried mocking thr form post but its complicated and has various scenarios based on the original webrequest querystring. any pointers.... i know its not possible to probably run JS code that posts the form - from within c# code but still thought of chekcing if someone has done that.

  • Determining Long Tap (Long Press, Tap Hold) on Android with jQuery

    - by Volomike
    I've been able to successfully play with the touchstart, touchmove, and touchend events on Android using jQuery and an HTML page. Now I'm trying to see what the trick is to determine a long tap event, where one taps and holds for 3 seconds. I can't seem to figure this out yet. I'm wanting to this purely in jQuery without Sencha Touch, JQTouch, jQMobile, etc. I like the concept of jQTouch, although it doesn't provide me a whole lot and some of my code breaks with it. With Sencha Touch, I'm not a fan of moving away from jQuery into Ext.js and some new way of doing Javascript abstraction, especially when jQuery is so capable. So, I want to figure this out with jQuery alone. I've been able to do many jQTouch and Sencha Touch things on my own using jQuery. And jQMobile is still too beta and not directed enough to the Android yet.

  • Email form isn't sending

    - by Jonathan
    Hi I have an email form that isn't sending out an email to the recipient or a copy to the client. The form can be found at www.kelcos.co.uk/contact and the files associated with this are: /index.php /jquery.js /sendemail.php /submitform.php /thanks.php /verify.php I have used this form on other websites http://www.bowlesgreen.co.uk/contact/ and http://www.arbortectreecare.co.uk/contact/ and it works fine - the only difference is that these other sites use my usual hosting provider and for the one that won't send I'm working through the clients hosting provider, which I can only presume is what is causing the problem. I have contacted the hosting and so far we have eliminated a few things such as: 'The limitation to our systems is that the emails sent using scripts will be blocked if they are not going to or coming from an email address setup on the web hosting account. - so I am now sending the form to an a kelcos.co.uk address, but still no joy. PHP/ASP was originally disabled, but now has been activated the mail() script is enabled I would really appreciated any advise any of you could offer. Thanks

  • Uncaught TypeError: Converting circular structure to JSON

    - by ychia
    We're using the fb:registration plugin to sign up users on our site. Today I noticed the registration redirect is no longer working in Google Chrome and Safari (latest public release). I know for sure it was working with the same code as recently as last week. It seems to be getting stuck on submission with this error, which is coming from: static.ak.fbcdn.net/rsrc.php/v1/ys/r/ioE9qOq_5Oa.js:101 Firefox and IE have no problem, so it seems to be Webkit specific. Any ideas?

  • Accessing a parent scope from a child directive

    - by zok
    The following code does not work. Apparently I cannot access someFunction() from child-dir. Is it a matter of accessing a parent scope from a child directive? How to do it, when the child directive comes from an external library? Angular/HTML: <parent-dir ng-controller="parentCtrl"> <child-dir ng-click="someFunction()"> </child-dir> </parent-dir> JS: .controller('parentCtrl', function($scope) { $scope.someFunction() { console.log('hello'); } }

  • Javascript instanceof & typeof in GWT (JSNI)

    - by rybz
    Hi, I've encountered an curious problem while trying to use some objects through JSNI in GWT. Let's say we have javscript file with the function defined: test.js: function test(arg){ var type = typeof(arg); if (arg instanceof Array) alert('Array'); if (arg instanceof Object) alert('Object'); if (arg instanceof String) alert('String'); } And the we want to call this function user JSNI: public static native void testx()/ *-{ $wnd.test( new Array(1, 2, 3) ); $wnd.test( [ 1, 2, 3 ] ); $wnd.test( {val:1} ); $wnd.test( "Some text" ); }-*/; The questions are: why instanceof instructions will always return false? why typeof will always return "object" ? how to pass these objects so that they were recognized properly?

  • What's the role of the parentheses in the following piece of code?

    - by Emanuil
    This is the tracking code for Google Analytics: var _gaq = _gaq || []; _gaq.push(["_setAccount", "UA-256257-21"]); _gaq.push(["_trackPageview"]); (function() { var ga = document.createElement("script"); ga.type = "text/javascript"; ga.async = true; ga.src = ("https:" == document.location.protocol ? "https://ssl" : "http://www") + ".google-analytics.com/ga.js"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(ga, s); })(); You can see that the function is inside parentheses. Why do you think is that?

  • Getting javascript mouse position relative to website prefferably without jQuery

    - by Constructor
    I've found this snippet on Ajaxian, but I can't seem to use the cursor.y (or cursor.x) as a variable and when the function is called as such it does not seem to work. Is there a syntax problem or something else? function getPosition(e) { e = e || window.event; var cursor = {x:0, y:0}; if (e.pageX || e.pageY) { cursor.x = e.pageX; cursor.y = e.pageY; } else { cursor.x = e.clientX + (document.documentElement.scrollLeft || document.body.scrollLeft) - document.documentElement.clientLeft; cursor.y = e.clientY + (document.documentElement.scrollTop || document.body.scrollTop) - document.documentElement.clientTop; } return cursor; } I'd preffer not to use jQuery UI if possible, since I've always thaught of jQuery and librarys as a bit of an overkill for most JS programing.

  • Using multiple SWF Object - Flash doesn't focus on rollover

    - by WiseDonkey
    I've got a page with multiple embeds of Flash objects, including dynamically created graphs. I'm including them all with SWF Object JS declared in the header. It works fine in the fact that all are loaded. But, for some reason when you move down on the page (so they're out of view) and back, or click on another object it no longer has focus when you're rolling over. I.e. I have a flash menu that moves on rollover. When you go down the page, click on something, then go back up it no longer response to rollover. I've seen bits on here and elsewhere about losing focus in Firefox (which is the browser Im using - i havent managed to find this bug in IE) but it's talking about literally not being able to type or whatever, when you click on it. This is on rollover. Has anyone got any advice or thoughts on this subject?

  • return a php associative array to javascript array

    - by Eric Sim
    I am trying to return a php associative array to javascript array through ajaxRequest.responseText Here's what I do. First in php, I do this: $encoded = json_encode($thisarray); echo $encoded; If I echo $encoded, I get {"a":"apple,arrow","b":"boy,bank","c":"cat,camp"} Then in js script, thisarray = new Array(); thisarray = ajaxRequest.responseText; If I alert thisarray, I get {"a":"apple,arrow","b":"boy,bank","c":"cat,camp"} That's wrong since alerting an array should give error. But in this case, when I alert thisarray, I get the full array!! Needless to say, I can't call my value out of thisarray, since it is yet defined as an array. Anyone can tell me what am I missing here?

  • Authenticating mssql users through different logins

    - by Sebastian Ferreyra
    I'm developing a new node.js based frontend for an old intranet site using mssql server and Classic ASP. Both the new and the old site will coexist during the transition phase and both must access the same mssql server using the same database principals. The old ASP/IIS site uses integrated windows login. The new node-based frontend has to use sql server based logins/principals (edit: while the IIS/ASP site must keep using Windows server principals) and all existing database users/principals must keep working wherever they login from. From reading around, it appears that a database principal can not be assigned to multiple server principals, therefore it seems unlikely there's a simple solution to this. I'd like to know if anybody has had to deal with a similar situation before and how they've gone about it.

  • Where can I find a jQuery color animation plugin?

    - by George Edison
    I need an up-to-date jQuery color animation plugin that works in IE 8. I tried using the one at http://plugins.jquery.com/project/color but it causes errors like "Invalid property value." in the following line of code from color.js: fx.elem.style[attr] = "rgb(" + [ Math.max(Math.min( parseInt((fx.pos * (fx.end[0] - fx.start[0])) + fx.start[0]), 255), 0), Math.max(Math.min( parseInt((fx.pos * (fx.end[1] - fx.start[1])) + fx.start[1]), 255), 0), Math.max(Math.min( parseInt((fx.pos * (fx.end[2] - fx.start[2])) + fx.start[2]), 255), 0) ].join(",") + ")"; Where can I get something that works? By the way, I really hate IE, if that helps.
