Creating A LED To Trigger An Alarm?
Jul 6, 2011I'm looking to create an LED like this:
in Javascript. I didn't know if this was possible at all. I have an program written in C that starts an agent and updates an XML file with data. I wanted to turn the LED on when the alarm was running, and have it off when the alarm was not running. I tried searching "LED in Javascript" but nothing came up. The image above is a LED created in a program called Labview, which I use frequently. I just trying to figure out how exactly to create one in Javascript.

View 2 Replies View RelatedDOM Modification Speed - Adding Elements
Nov 12, 2010I'm justing wondering about the behavior of JS in regards to adding elements, suppose I have something like this:
I'm just wondering at the point I hit that "// DO SOMETHING WITH ONE OF THESE DIVS", are all the divs I have added in the DOM available to access?
I ask because I have some code at work in which a tester is reporting an error that happens which I can't reproduce, and they and others have had it a few times.
The only way I can explain it in my mind is if the div is not available to me at the time of execution. So I'm just looking to rule it out or confirm my hunch.
Is document.getElementById("myDiv").appendChild(obj); synchronous and the next line of code wont execute until the DOM is ready or is it in fact a asynchronous call and therefore adding alot of elements to the DOM could result in a lag so some divs or not available straight away.
Auto Sum Order Form Modification
Jul 14, 2010I needed to calculate my prices on-the-fly and display it in textbox with javascript. Well I did succeed with values of radio button an checbox, but as I know very little javascript, I don't know how to expand the code I got from here: [URL].
How can I make this happen: I have a textbox:
HTML Code:
<input type="text" name="podstranice" size="19" class="podstr" onkeyup="this.form.total.value=calculateTotal(this);">
And when a user inputs a number in it, javascript multiplies it with some other number, say 10 (its a price*quantity thing) and adds it to the total price along with data from checkboxes and radio buttons. And so, this is my javascript. It is basically identical to one on the link, but you can view it better this way I think.
Code:
// Calculate the total for items in the form which are selected.
function calculateTotal(inputItem) {
with (inputItem.form) {
// Process each of the different input types in the form.
if (inputItem.type == "radio") {
// Process radio buttons .....
Logic Error On Limiting The Modification To The Maxvalue ?
Feb 26, 2011How to create a function that would allow me to add to or subtract from a maxvalue, and thankfully I got help regarding that. However, something's got me stumped for the past few weeks that I still can't resolve...
This is the relevant code:
As it stands, it works as long as the total value is less than or equal to the limit (for advantages it's 15, for disadvantages it's 10). However, the moment it goes past the limit -- for instance, if you change Antisocial's value from 2 to 7, or if you add several additional checkboxes with any values -- the whole thing starts going crazy; specifically, maxvalue doesn't revert to 40 when the all the checkboxes are unchecked.
What I'd want to happen is that the user cannot select or apply advantages or disadvantages if the maximum advantage is greater than 15 or the maximum disadvantages is greater than 10.
I'm thinking that a button for adding disadvantage points to/subtracting advantage points from the maxvalue (that becomes disabled if the user goes past his limit on advantages/disadvantages) is useful at this point, but I'm really stumped on the implementation of the idea. An alternate idea of mine is that all other advantage/disadvantage checkboxes would become disabled if their value is greater than the remaining number of points, but I don't know how that is possible either.

Update Order Form Without Page Refresh Modification
Feb 4, 2010[URL]. I looked at this script and I tried playing around with it but could not figure out how to: Instead of having a check box field and then a radio box field, have 2 radio box fields, so the user picks from one group of radio boxes and then another. Then change the math behind it so the values in the first field are multiplied by 100 and then the values in the second field tack on a percentage (ex value in first field is 1.5 so 1.5x100 = 150 and value in second field is .5 so total is 225).
View 1 Replies View RelatedJQuery :: Using $(document).ready(function() On Elements That Are Created Via DOM Modification?
Mar 14, 2011I use the following code to add a "click" behaviour to an element:
$(document).ready(function(){
$("#element_id").click (function(){
...... do something ....
[Code]....
Part of the node I clone is the element from the first piece of code I quoted. The addRowJob function also changed the ID of every element in the node I cloned. This way all IDs remain unique. Lets say the element in question has the ID "#element_id". Now I clone the node (which includes the element) and the cloned element gets its ID changed to "#element_id_new".
Of course I now want this newly append element ("#element_id_new") to have a click event attached to, but even if extend my $(document).ready(function() to:
$(document).ready(function(){
$("#element_id").click (function(){
...... do something ....
});
[Code].....
I simply doesn't work for the appended element.
My guess is that the $(document).ready(function(){ only fires when the document is finished loading. At this stage there is no element with the ID "#element_id_new" and therefore the click event can't be attached to the element. Makes senses...
But how do I get this click event attached to the newly appended element with the ID "#element_id_new"?
Ajax :: Modification - Function To Load Text File Information From The Server
Sep 24, 2011I have been successfully using the following "myAjax" function to load text file information from the server.
ajax.js:
After I load the text file, I store the text "records" into an array by doing something like this:
Where the '}' character is my record delimiter. It could just as easily be ' ' or ' ' or the like.
Again, I am not having any problems doing it this way as it suits my current needs.
Now the question(s)
1. Does the call to read the text data from the external file always read in the entire contents or can I read one line or delimited record at a time and store it to the array directly without the text storage?
2. If the text is always read completely (my suspicion), can I safely delete the "TextInformation" after I convert to the array format? Is there any memory penalty for doing it this way as the text information can be somewhat lengthly and I don't like the idea of having doubled memory usage when I only need the information in array format anyway?
This is the idea I am considering, but I don't know if there are drawback to this method of if there is a better way to accomplish the task.

Form Posting To Itself Wipes Out Dom Modification When Redrawing Form
Jan 16, 2011I have a webpage with a form inside it. Below the form is a div. When you submit the form it executes some javascript that adds a bunch of html to the div. I can step through the code in the Chrome debugger and see my dom changes are there, but disappear as I get to the original tags in the page. Is there anyway to prevent this?
