I try to make a script which check's input's value every time when value changes. There must be ready example somewhere, but I just could not found it. The value shoud be hex-color-value (like #FFFFFF), so script should check if the first character is # and after that only characters a-f, A-F and 0-9 are ok. I guess it goes something like this:
function checkHex(value) {
// if value string includes only characters # a-f A-F 0-9 value is ok
// else value is not ok
}
<input type="text" id="hex_input" onkeyup="checkHex(this)" />
I have an online shopping cart and some of the products are sold in boxes of 6. So I am trying to write some code that will alert the customer if they have entered a quantity that isn't some multiple of six.
I've tried using the modulus operator as well as dividing by 6 and then checking to see if the result is a whole number but inevitably the alert box pops up no matter what I enter.
This is what I'm trying to use now:
Is there a better way to check if the entered quantity is a multiple of 6?
So I have a new window document write which outputs all my data after validation into a new window, I have tried to write a button which will (when clicked) send that information to an email address. here is my code so far. i spent about 2 hours checking and playing around looking for errors couldnt find any. I think the problem is the function EmailForm and function subwrite. Is a button written into a new window a common thing to do? or is there another simpler way, however i want the user to be able to check to see if there data is valid and then click to send the email.

I have an input textbox that I am using to create (and populate) paragraph tags below it depending on the content that is in the textbox at that very specific time. There is an add button to the right of the textbox that adds the contents and clears it for another entry.
The reason I need keyup for this is because I need to get the value of the textbox on the fly. With the example I've enclosed, it seems to output every key event since page load, and I don't want that. I want the result from the last keypress, which I will then add and start again.
How would i make it so basically everytime you keyup it would post that data in the url without refreshing so when a user clicks on a link they searched for and go back it will have whatever they typed last in the search bar?
I'm having trouble setting this keyup event w/ jquery. The first alert fires fine, but the second alert doesn't. This is driving me nuts. My textbox does have the name and id set to "typename".
I am using the following code to add a keyup event listener to the body tag. It works fine in Webkit and Chrome but FF and IE just do nothing. The event never fires. However, no javascript errors occur in any browser.
here is the code:
Code:
var Body = new Object(); Body.trackKeys = function (target){ if( document.getElementsByTagName("BODY")[0].addEventListener ) {
I use this code to create a div element with inside a text and a button, for than adding this div in a cell of the jquery grid. Everything works fine with firefox and IE instead in chrome I found out with alerts that only the click of the button is added, the other handlers like change and keyup NO or are not triggered.
myJQGrid.myElemKodi = function (value, option, disabled, lastsel2, id) { var el3 = $('<div></div>'); var textField = $('<input type="text" />');
I'm doing some customisation on existing software - my objective was to reflect changes to a form in a separate table.The forms require the user to enter numbers and these are totalled in the final formfieldvia an existing 'onkeyup' function.I used keyup to copy the value typed and add it to the summary table. However in doing this, the existing 'onkeyup' function written into the form no longer works and so the total is no longer displayed. I tried using keypress instead (which still had the same issue), or including the function from the onkeyup in my keyup function, but it just didn't run.how to work around this? I can't modify the existing code.
I would like to restrict Character limit on TEXTAREA box.I am able to get char limit using Jquery if it it is one textArea. limit chars for Multiple TEXTAREA in same page using jQuery Code.
<script type="text/javascript"> $(document).ready(function() { // ---- How can I do on keyup $('textarea
Im trying to add a class to an element when the down arrow is pressed using keydown but once you release the down arrow the class is removed from the element.Is this normal behaviour?
The reason I ask, is I have a barcode scanner and I want to be able to trigger a submit button next to the matching product on scanning the barcode. So basically, the user can open the page (and may have clicked on some elements already) then scan a product which will input a 13 digit number and the submit button with that matching id will be clicked/submitted. This is easy enough to do if I use a text input, but I a) don't want the user to have to click in the text box first. b) don't want the user to have to delete the text box to scan the next product.
Perhaps it can be done somehow with a hidden field that automatically resets on each scan?!?
The scanner works just like a keyboard as I have used it to filter products with keyup() in a text field...so it does actually activate keyup(). So it should have exactly the same affect if you type the numbers manually.
I'd like to use the jquery validation plugin. According to the documentation, validation on keyUp or onFocusOut should be enabled by default. Is that not the case? Even setting these options to true, I cannot seem to get them to work in that plugin.
why the following code (which counts the remaining allowed chars in html-textarea) does not work in Firefox although it works in all other browsers, IE including?
Im using keyup function to track text typed in input box. The idea is to perform incremental search in db. This works fine. After this I update the html dynamically to display the filtered resuts and at the same time I must dynamically rewrite the html for input box code. After this the keyup function is not working anymore, allthough the id tag is the same? How should I get around this?
I want to 'style' all links on my site with a variable for random colors. I got the variable for the random colors up and running but i can't figure out how to implement the variable to the css.
Explain why when the lines of code that are commented out are reintroduced that this code breaks instead of resulting in each of the four circles being a different color?
There are two radio buttons, sometimes one will be disabled, other times the other will be disabled. I would like to make a script that: First: Changes the color of surrounding text of the disabled radio button to the color grey. Second: Checks the other radio button.
This was my plan: I would make a script that: First: Removes all the current classes and add the class "greyed_out" (or better: change only the color of) the parent element, all siblings and children of siblings (if any) of the radio button that is disabled at that time.Second: Sets the attribute "checked to the other radio button". I made a script, but when I set the bottom radio button to disabled the script doesn't work:
have been trying to rework this to call additional, independent sets of colors to cycle through (so it would loop thru a set of grays, a set of primary colors, etc). I would use perhaps a different function name in the HTML to call different sets of colors. If this is more complex than I think it is, I think 3 sets would be plenty. demo link of script in current state at bottom)
I have created a javascript script to select a color for the css theme. I have it working great for picking, but the problem is when I refesh it goes back to the default. why my cookies are not saving?
