JavaScript - Bluetooth Controled Smart Lighting For New Product Similar To Hue. Need Some Tips!
Hello Coding Forums,
I am working on building a watch app for the Pebble smartwatch that works in combination with a Bluetooth light bulb that could trigger on and off functionality. I have bits of the source code from a the same bulb project someone started from another site that is coded Java, so I imported them into cloud pebble their java library. I've been working on this since last year and I'm wondering what at all could I be doing wrong. I get the "cards" to show up, but as far as a connection to the bulbs I have not established that yet. I've attached my source code and if anyone has any time to give me some pointers that would be appreciated massively. I know that Hubble worked on a similar project, to control lighting from a pebble smartwatch so I know it can be done. I've even tested this code with other developers who are experienced and they are also wondering why the connection does not take place. It would be really neat if I got this to work. Thank you everyone. Attached Thumbnails Similar TutorialsI have built a signup form which has several text inputs and text areas. Their labels are set as their values. When the user focuses on the field, the label text is cleared to accept text input. When focus is changed to another field. The field checks if text has been entered. If it has not, it then resets the value back to the default label value. For example: Code: <input type="text" name="company_name" size="50" class="textInput" value="Company Name" onfocus="if(this.value=='Company Name')this.value='';" onblur="if(this.value=='')this.value='Company Name';" /> What I would like to do is have some simple javascript which checks the fields on submit. If any of the required fields still have the default label value, then I would like to change the colour of the label value in the input to red and disable the form submit until the value is corrected. Most of the inputs and text areas will accept any text, though one is an email text input. I don't think any fancy validation is needed for this email input , other than checking to be sure a '@' has been entered. Since the website that this form will be contained in runs jQuery, I have looked into some plugins for form validation. However, these seem to be over-complicated for what I need. I want to keep this as simple and light as possible. Oh, and also, I am not allowed to use anything php based as this is not allowed to run on our servers for security reasons... Any advice or suggestions are much appreciated! Hello all, I have written a javascript code to take the users Zip-Code, and make an alert come up with minimum purchases for free delivery. However, I have made this backwards from what I really need. I need an On-Load alert so customers can set their Zip-Code, and then print into a div the information needed. I also need this to store a cookie so the customer will not be forced to enter their information on every page visit. I have included a truncated portion of the script (it is over 850 lines) Code: function message() {
zipcode = document.ZipCode.txtZip.value
if (zipcode == 33820) {
alert("Minimum purchase for delivery: $300.00" + '\n' + "For smaller orders, please visit Packitright.com at:" + '\n' + "http://packitright.com")}
else if (zipcode == 33920) {
alert("Minimum purchase for delivery: $235.00" + '\n' + "For smaller orders, please visit Packitright.com at:" + '\n' + "http://packitright.com")}

Any assistance would be greatly appreciated. Hi, I can;t think what to search for but I need the following. I am running a form and if data is entered to the first text box, I want a warning message to show up, if they try to add data to any one of several other textboxes. tips on search terms would be great or a link to what might be some loosely appropriate code. bazz Okay so as you could tell by the unfamiliar name, I am a newbie. I have completed the codeacedmy Javascript course and while I know it's not the best for actually getting GOOD at at, it's still taught me a bit. I'm, working with a buddy of mine who is urging me to begin working on something ASAP so that we can start a project together. I suggest making a short RPG, but I'm unsure how I can begin with something like that and what I would need to work on. Or if you have any other projects you can suggest as a good first project to get my feet wet I would be extremely grateful for the help. Thanks in advance!
Hello, I'm new to this forum. I want to improve my ability to write JavaScript and am looking for a friendly place to find some constructive criticism and suggestions on my code. This script does not have any practical use (that I can think of); it calculates prime numbers. It is just an exercise. I am looking for suggestions on all aspects from the CSS/aesthetics to the HTML and of course the JavaScript. I posted the script here. One definite thing that bugs me is the cursor is not in the text field when the page loads. Also it would be better if the user had the option of hitting the return key in addition to the submit button. Suggestions appreciated. Code: <!DOCTYPE html>

I would like to ask people's opinions as to which "offline" language is most similar to javascript? I don't program for a living, but I have been learning javascript in my spare time. I would now like to have a shot at making a desktop application, and I think it would help to choose one which is most similar, if at all possible, to javascript? e.g. python, ruby, C#, visual basic ... I have no idea and haven't had much luck googling this Thanks Matt Hello, I have the code in the annexe wich is working but grossly redondant, clearly, I would like to have only one function toggleEditor(), that would manage the global variables editInstance with a parameter or something equivalent to avoid having 2 twin like functions. Thanks for your suggestions. HJS Annexe : Code:

<body>
<script src="../flovinax.js" type="text/javascript"></script>

var editInstance= null;

editInstance = new flovinaxa({fullPanel : true}).panelInstance(edtN);
} else {
editInstance.removeInstance(edtN);
editInstance= null;

var editInstance2= null;
function toggleEditor2(edtN) {

Hello all i need to be able to make small peace of js code that the user can drag to is IE browser and then invoke it on the page . Hi, I need to allow some other websites to show certain portions of my website as though it were part of theirs. Simplest way would be in an iframe, but I would prefer to make the content available similar to the google map api where something like this is included in the header:- Code: <script src="http://maps.google.com/maps?file=api&v=2&sensor=true&key=blahblahblah" type="text/javascript"> </script> and in the body something like this:- Code: <div id="map" style="width: 740px; height: 520px; margin: 5px 0px 20px 0px; padding: 5px; border: 3px solid #FFDD00;"></div> So I am guessing that something in the file being called in the src of the script tag is replacing the div with id="map" with other contents. Can someone give me a simple example of doing this? Thanks. I have searched for a rotating image script to use at mrsgriffins.com and am currently using Tony Foster's Picture Cube slideshow downloaded from javascript.com. This is EXACTLY the effect I wanted, but it only works with IE since it uses MS-only code. Is there a similar script that is more universal? Thanks for any help! http://www.premierleague.com/page/Ga...047853,00.html
So what I'm actually refering to is something similar to facebooks sign up page. Where you have a form and you start typing the name of a high school or college and they automatically match what your typing in a drop down window. Here's an example pictu Any help pointing me in the right direction would be outstanding. Also I am pretty sure this is javascript, so I figured this was the right section for it. Thanks in Advance, Ryan I have created a slideshow before but I want to create a slideshow where a person clicks on a link and it goes to a certain picture which might have one or more links embedded into the picture something like this: http://www.myeloma.org.uk/ any guides on how to do this? help much appreciated Hi There, I really need your help. I am aware that there is no isDate() function for javascript, however, how could one check a date against a validator to ensure that the date entered is either returned true or false the date format that I would like to check would consist of the dd/mm/yyyy so essentially: isDate("12/01/2012") would return as true isDate("N/A") = would return as false I have searched high and low and am counting on the experts on this forum for some major help. A huge thanks in advance and I really appreciate everything. Cheers, Jay I have created a program that works great but sometimes it does not finish. It is the exact same as the one we see in this forum when you want to insert an image into a forum post. The program takes in a users image url through prompt, then regenerates the information within the textbox with [img] tags. The problem is I try to do this once and it will work great, but then I will try it again and fill out all of the information the exact same way and nothing happens. By nothing happens I mean after I hit enter the text box will remain empty with no regenerated code. But if I do a page refresh it works. That leads me to believe there is nothing wrong with my code b/c I do it once and get a sound result, then again and get nothing. Anyone have any experience with broken programs like this before or any words of advice? PHP Code: <script language="javascript"> function imgGenerator(){ var question=confirm("Share a Picture?"); if (question==true){ var obj=document.getElementById("mngl-board-post-input"); var imgurl = prompt('To Share an image paste the image url here \nSupport .jpg .jpeg .gif .bmp and .png'); if (imgurl == "" || imgurl == null) {return false;} var txt=document.createTextNode("[a][img]"+imgurl+"[/img][/a]"); obj.appendChild(txt); } else {} } </script> PHP Code: <a href="javascript:void(0);" onClick="imgGenerator();"><img src="http://instride.org/images/image.png" alt="Share an Image" /></a> The code I will am including is far from finished, but some of what I do have works (the "submit" code does not work yet). I am able to prevent certain kinds of input including Shift-Ins pasting, but Ctrl-v pasting still works (and I do not want it to). Could you please tell/show me what code needs to be entered to my existing functions, or what new function I need to create (and call from my existing functions) to eliminate any kind of CtrlKey input?

One cool aspect is for the online user to be able to type in what they want on the stationery, choose the font, and hit a "PREVIEW" button, showing an exact preview of what it should look like. I am having trouble on how to do this. Virtuemart and its forums are useless and helpless. Joomla suprisingly doesn't have an extension for this. Looks like I'm gonna have to hard code this baby. What would the best angle be to attack this? Should I try some interactive flash/AS3 or some good ol JS? There will be over 500 products so I am trying to pick YOUR expert brain before I tackle this beast. Thanks for any input! Hi, I'm trying to recreate Apple like product browser. Now I downloaded entire page from Apple web site and I was able to isolate CSS files and java script files responsible for creation of this browser. It works just fine on my computer. But when I pull out all the CSS files and group them as well as Java Script files it just wont work any more. CSS works just fine after I relink them to a page but Java Script wont. Any clue what might be a problem? By the way I'm not trying to steal it from Apple. I just need engine to see how it is done and then I will change design since there look doesn't feet well with my web site design. So I guess it is OK. //*Below is the code that i can't get to work.
