Need a simple answer for my Javascript, please?

In my CF application, I need to add a javascript to validate text fields.
I already have the script, the bad news is that there was an another javascript for this same text fields where its
the feature is for the calculation of the number. This existing script uses OnKeyUp for these text fields where I'm supposed to also use OnKeyUp validation control

I'm not expert javascript and have tried to put 2 OnKeyUp in same text fields and my attempt causes the validation script does not.
How can I use my validation script for the same text field where the calculation script has used OnKeyUp event handler? Help, please!

Here's what I can't understand:

My script to prevent the user to enter special characters when you submit data

< script language = "JavaScript" >

var mikExp = /[$\\@\\\#%\^\&\*\(\)\[\]\+\_\{\}\`\~\=\|-]/;
function checkeachfield (val) {}
var strPass = val.value;
var strLength = strPass.length;
lchar var val.value.charAt = ((strLength) - 1);
If (lchar. Search (mikExp)! = -1) {}
TST var = val.value.substring (0, (strLength) - 1);
Val.Value = tst;
}
}
//
< /script >

Here is the part of the script for the calculation of the number. I'm not suppose to edit this script:
< script language = "JavaScript" >

function calctotal() {}
document.cost.F2.Value = document.cost.f1.value * 0.25;
document.cost.F5.Value = document.cost.f4.value * 0.25;
document.cost.AL2.Value = document.cost.al1.value * 0.25;
document.cost.AL5.Value = document.cost.al4.value * 0.25;
document.cost.NF2.Value = document.cost.nf1.value * 0.25;
document.cost.nf5.value = document.cost.nf4.value * 0.25;
document.cost.nal2.value = document.cost.nal1.value * 0.25;
document.cost.nal5.value = document.cost.nal4.value * 0.25;

var F1 = parseFloat (document.cost.f1.value);
var F2 = parseFloat (document.cost.f2.value);
F4 var = parseFloat (document.cost.f4.value);
var F5 = parseFloat (document.cost.f5.value);
F8 var = parseFloat (document.cost.f8.value);
var al1 = parseFloat (document.cost.al1.value);
...............etc
< /script >

<! - I don't know how to call these 2 functions of these text fields - >

< input name = "f1" type = "text" onKeyUp = "calctotal (); ' value = '0 '.
onKeyUp = "javascript:checkeachfield (xyz.f1); » > ???

< input name = "f2" type = "text" onKeyUp = "calctotal (); ' value = '0 '.
onKeyUp = "javascript:checkeachfield (xyz.f2); » > ???

< input name = "f3" type = "text" onKeyUp = "calctotal (); ' value = '0 '.
onKeyUp = "javascript:checkeachfield (xyz.f3); » > ???

Several text fields to look for special characters












> The first function still works but not the second function

  • Need a Simple answer to the question Simple Contribute/Firefox

    Hello all;

    I tried using Adobe CS3, technical support, telephone support, this forum, other forums, Mozilla, and nowhere can I get a straight answer, so I'll try one last time before giving up on Adobe products.

    I have CS3 Web Premium. The entire suite is on the iMac and MacBook Pro. I need to update a Dreamweaver site on a trip with a MacBook Air.

    Please help me understand this.

    Contribute apparently has the ability to put a plug-in in Firefox, then you can update the remote sites. It is not clear from all sources above if the module of the suite of Contribute must be on my MB Air, or if I can just get Firefox for the MB Air card and put in place the web site for the distance of publishing using Contribute on the iMac.

    It would be the simplest: use Ct on the iMac to some portions of the site for editing by using Firefox from the MB air. It seems simple enough for me but no one or no info I can find can confirm or deny that this is how it would work.

    Please, if anyone knows if this is how the thing works, save my sanity and convince me to stay with Adobe products to let me know if I'm right and how to get the Firefox plug in.

    Thank you!

    My dear think;

    Thanks for the reply, you're right that it's as simple as that.

    I'm a little confused how this is a good solution, if you need to have on your mobile machine Ct, you would also be more or less must have Dw there (if you use the Web Premium package), then why would you also need of a plugin Firefox?

    I have this huge and capable package on iMac and laptop family but I am not allowed to use one of his abilities, even the smallest, or a plug-in compatible with, a third machine. So far from home, I have to either spend a lot more money on another piece of software for the few times of the year I travel, or return to raw html in a basic text editor and an ftp program. All I want to do is change one page per day with some new features.

And then becomes, where if these big cats there products on line for free, they do not work but for so long, then they really don't work at all! And then you have to buy something they claim works, when you have to ask yourself, if the other did not, and it's free whay makes U think that this next paid for thing will be? When in all reality, it's really the same thing as the first free thing does. Let's face it you know it's true!

When in all reality, it's really the same thing as the first free thing does. Let's face it you know it's true!

    First of all, please note that the word "malware" is short "Malicious software." it means software that does bad things. The term includes viruses, spyware, Trojans, worms and rootkits. etc.

    Here are my recommendations: for an anti-virus program, I recommend eSet NOD32, if you are willing to pay for it. If you want a free anti-virus software, I recommend one (do not run more than one) of the following three:

    Avira AntiVir
    Avast
    Microsoft Security Essentials
     
    You also need anti-spyware software (even if you run a program like Microsoft Security Essentials, with anti-spyware feature integrated into it). I recommend that you download and install MalwareBytes AntiMalware (freeware)

    Oracle do not publish the detailed browser compatibility requirements. The basic requirements are covered in the documentation.

    Tests in the new version of browser applications are necessary to ensure compatibility. Test should focus on the components of the nonstandard application (such as plugins, themes, existing or custom and models and third-party JavaScript libraries) and the browser features such as compatibility and security modes.

    Thank you for your help,

    CS5 has native support for AVCHD... for CS4, I think that you must convert to HDV (or, perhaps, to buy a commercial CODEC to install)

    Do a search for

    I don't see Installing a browser 2011 in a 2007 operating system. I replaced Xandros with Easy Peasy 1.6 some time ago, 3.0 and 3.5 were too darn slow on Xandros even with the GTK update. A 900MHx processor will never be a speed demon, but you I have to give him a chance with a better than Xandros OS.
    Personally, I stay with 3.6.x until the end of the support. I don't see the need to upgrade to the latest version of Firefox now, especially on Linux.

  • Help needed to convert ActionScript 3 for HTML5 javascript

    I'm looking for help conversion code actionscript 3 in javascript for a platform of HTML5.  I'm a developer flash by trade but I am not familiar on how to 'translate as js code.  I had recently downloaded CC animate, thinking that he take the existing .fla file and republish on a html5 format.  Well I was wrong.  All of my code that I used in flash gives me hundreds of errors & I have not even know where to begin. the question I have is: all my flash documents I created over the years must now be converted to html5.  Where do I go, who can help you? is there an easy way to do this? is there an online converter...  I need help! Thank you.  Here's an actionscript exsisting code that I need to convert: sorry for the copy and past of the script.

    The severe and simple truth is that you will have to re - write everything from the beginning in JavaScript (aka ECMAScript).

    The good news is that JS syntax and functions are 99% identical to AS2. Transition to AS3 will be slightly more difficult due it it is a little more similar to Java.

    The bad news is that all the APIs are completely different. Flanimate in canvas mode uses CreateJS for all rendering, animation and preload. Another thing is the basic JS functionality, or it either library third you import yourself.

    For example, instead of:

    var thirtySeconds:Timer = new Timer (15000: 1);

    thirtySeconds.addEventListener (TimerEvent.TIMER, thirtyDone);

    You would do:

    var thirtySeconds = this.setTimeout (thirtyDone, 15000);

    And instead of trace(), you must use console.log (), since all code must run in a web browser.

    Your computer came with XP? If your computer came with VISTA and was never made for XP, so no XP drivers will be available for the system. I looked at the HP site and could not find XP drivers, which probably means that it is a model of Vista, not XP.
