JQuery :: Transforming Input As It's Typed?
Aug 12, 2009
My workplace has a lot of people doing manual entry. I'm looking to provide some friendly automatic formatting of data as they type it. I have working code (thus far) but I want to ensure I'm doing things in a sane way (there's a surprising amount you can do insanely that still works Here's a function below that transforms a phone number - the worker enters the digits(only), the field reflects (and could also accept) the fully formatted version (e.g. (123) 456-7890 ). I'm building this towards a plugin model (ala masked input with happy

I'm trying to validate the text of an input as it is typed.I have this keyup:[code]The idea is that only let the user type a decimal number; and it does.The only problem is that it let type a dot [decimal separator I need] at the beginning; and I don't want that.I've been a while and searched Google for the Reg Exp, but had no luck.

I want to run a function when text is typed into an input field. So every time 1 character is put in it will process a function. However I do not know how to accomplish this. I tried the onchange attributed but that seems to only work when you unselect the input field.
how this might be accomplished? I'm also comfortable with jQuery if you think that's a better option.

I'm creating a page that calculates a number depending on what value is inputted into a text field. I need to create some javascript that updates this new calculated value and outputs it next to the input field. Anytime the user changes the number, it recalculates the value. My calculation is currently being produced by PHP, however if I need to, I can create javascript as well to recalculate these numbers.

Do any of you know if you can convert a JSON object into a Jquery object ? The reason i wish to do that is to be able to use the jquery selector to filter my Json data. (for example filter them based on their properties)

I wrote this function to be a change event applied to a checkbox. Now it is apparent I need to use it as a custom validator method, so it runs when you hit "Next" to step through the form. I have all that working, I just can't get the syntax of the rule right.
Here it is as a change event:
$(
'#MKDPT'
).change(
function(){
if(
$(
'#MKDPT'
).is(
':checked'
)){
var
checked
=
false
; .....
And my attempt at a custom validation rule:
$
.
validator
.
addMethod (
"MKDPTOnly" ,
function (
value .....
I have tried several versions, but none is letting the form go to the next step (return true) if the conditions are met.

If I have some XHTML that I want to transform into something else through JS (say I have a list of links to images and I want to transform it into a fancy JS-based slide-show), and I do this by calling some JS code in window.onload (in an external .js file).
The page starts loading, then the list is displayed, then once the whole page has been loaded the JS is processed, and the list is then turned into the fancy JS slide-show. The problem is, it's not very nice to *first* see the list, and then see it disappear and be substituted by something else by the JS. What would be the best way to hide the list?
I don't want to hide it with CSS because it should be visible for non JS but CSS capable agents. I came up with:
<ul id='foo'>
<script>
document.getElementById('foo').style.display = "none";
</script>
... the rest of the list follows
But I hate that script block. Any ideas?

my page allows the user to enter a number in a text box and a search request is sent to the server (if the user stops typing for 200ms) using AJAX. The following is the desired behavior.
(1)User starts typing a number in the text box. As the user is typing, no search requests are sent to the server.
(2)Once the user stops typing (i.e. no key events for 200 ms), use $.post() to execute a search.What is a good way to detect that the user hasn't typed anything for 200 ms?Is there anything in JQuery that I can use?

I'm working on creating a custom calculator to determine the amount of money / credits users may earn from referrals. I've tested onChange, and it will work only when I have changed to a new field or clicked off that field. How do I make this calculate live?
So if the current value is 5 and I change it to 6, it will automatically recalculate the new value.
You can see what I'm working on here:
[URL]
Note: The one I'm testing is the 1st Level field. For now i'm just having it display the date.

My client has a training site that is associated with 4 different domains. If a user navigates away from one of the domains to another site (for instance google or msn) they want to display a message and ask them if they want meant to leave the training site. my understanding of the window.location.href is that it will not capture what is typed into the address bar until the request is submitted to the server but by then they are leaving the site. below is my code on the onbeforeunload event. concept: i want to capture the URL, compare the hostname and if the host name is one of the 4 domains then allow them to proceed if it is not then as them if they want to leave the site. if they click ok allow them to move forward, if the click cancel then reload the page. I know this is considered bad design and i have expressed this but this how they want the site to behave.
<script type="text/javascript">
function SiteCheck()
{
var strCurrentURL = window.location.href;
var strNewHostName = strCurrentURL.split("/");
//
for(i = 0; i < strNewHostName.length; i++)
{
alert(i + ' ' + strNewHostName[i]);
}

I want a script that "types" my text letter by letter and also deletes the text letter by letter. I want it to look as if someone is typing the text live, and then when the start of the text deletes (letter by letter), it would start from the beginning, erasing the letters in the same pace new letters are being "typed". So this way you would never see the whole text, but only a bit of it at a time. By the time you would get to the end of the text, the beginning wouldn't be there. And I don't want the text in a box!

I am writing an HTML builder. On thing that I think would be helpful is if the user types in
="
A javascript adds another " for the user, but puts the cursor inbetween the two "'s. In other words, the javascript should assist users in writing HTML/Javascript codes. This may also be applied to < & >.
I have found this script that can get your position in a textarea. I also thought this might be of help:
Code:
var textarea = document.getElementById('code');
var tmp = textarea.value;
textarea.value = textarea.value.substring(0, textarea.selectionStart) + '"' + tmp + textarea.value.substring(textarea.selectionEnd);
Although I have tried, I have not been able to piece the scripts together.

I have a script that allows ONLY numbers to be typed into a text field. I have tried to modify this script to allow Decimals (periods) to be typed as well, but haven't succeeded. The code in Red are the changes I added to this script, but it isn't working out.
function numbersOnly(evt) {
var charCode = (evt.which) ? evt.which : event.keyCode
if (charCode > 31 && (charCode < 48 || charCode > 57) && (charCode < 110 || charCode > 110))
return false;
return true;
}
Second Problem: I need to set a Minimum number users may type in the text field. Normally this would be a simple task, but the minimum number they may type is a decimal (0.10). The default value in the field is .50. I tried replacing the .50 with .09, and I can't get the field to run the script and set its new value to .10 (<- this is the minimum). Here is the code I am working with.

is there a way to determine whether a user clicked on a link vs typed in the url to get to a page? I'm trying to stop users from messing with GET forms (and i have to use them, POST wouldn't make sense in this case).

I have been working with the jquery ui combobox but when I try to access it, it gives me what I believe to be the closest value in the select control. I'm trying to pull the value of what was selected or entered.
I'm using this in conjunction with asp.net. To eliminate that and just focus on jquery. If I had a combobox and a hidden field, upon leaving the combobox, how would I set the hidden field of the value that was either selected OR typed in.

im trying to implement a login screen similar to Facebook. What i mean by this is i want the username and password fields to have text in them until the user selects the textfield. If the user does not type anything in the textfield the the onblur will automatically change it back, but if the user has typed something in then i want the text to be left alone.At the moment the onblur always changes the value of the textfield. Im not sure how to solve this.(code i am using is below)
Code:
<input name='username' type='text' size="10" value="username" onfocus="this.value=''" onblur="this.value='username'"/>

I have a form with two text input boxes. I want to limit the text typed into the boxes as follows:
1. Either box can have the number 2 typed in, but the other box must remain empty
2. Each box can have the number 1 typed into
Is this possible with JS and, if so, how do I do it??

As recently as 1.4.3 $('input:text') would find input elements with no type attribute, but after upgrading to 1.5.1 that is no longer the case.
Is this a bug or an intended refactor to be more standards compliant?
FYI - this is the selector I now have to use: $('input:text,input:not([type])')

I have a pretty basic set of things I want to do: Capture key press, compare against an allowed list, block keys that are not in that list, replace a space by a dash if entered. As this is happening, I have a span I wanted to be updated with the live values. The username field at [URL] is exactly what I am trying to do, though I have trouble dissecting how they did it. Here is my attempt, which is off by one keypress for some reason.

I am having a form with two input fields. I want to enter some text in the first input field and then the second field should get the same text. Is there a simple way (maybe a plugin) to do this with jQuery? It would be perfect if I even could output all these input fields values as normal text in <p> or <li> tags.
