Run A Function When Text Is Typed In An Input Field?
Jul 15, 2011
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.
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.
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.
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.
How can I track what is written to an input field on the fly(event that is not "click" "hover" etc but something like "track" or "observe")?Lets say I have a js object like this:
var array1 = {id1: 'keyword', id2: 'execute', id3: 'go'};
I have a problem created by my complete [rookie] status – only second time venturing into jQuery. I created a simple shopping cart using php and the PayPal buttons (1: buy now, 2: add to cart). The php back end does it great, it generates the table and the buttons and everything works just like it’s supposed to; Except, I forgot to add sizes. So I found out what I need to add, and I realize that the way the buttons work, I will have two different text boxes for size. Not very visually appealing, and since I’m not submitting this to the server before it goes to PayPal to pay, I cannot modify it with php the way I normally would. jQuery / javascript are my only hope of making this work. What I want to do:Have a single textbox where [size] is entered by the user.
Copy the value from the [correct] text box to the Value=”” section of the now hidden field in the PayPal form That way, no matter whether they [BUY NOW] or [ADD to CART] the right size is submitted to the PayPal shopping cart. This is the actual PayPal code that I’m trying to change
I got this far, and then decided to find how to insert the "enteredVALUE" into the right place in the input text field (what I called output) and I've not been able to figure out how to stuff it in there.
I am trying to make some dynamic effect to a HTML page using JQuery.<br/> 1.<br/> When the user clicks a Radio field, the field will be highlighted.<br/> 2.<br/> When the user clicks the Radio 'Man', <br/>a Input text box will be provided immeditely just below it.
Here is my simple HTML page, but I don't know how to do with the JQuery part:
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
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)
Have a small problem with a cms whereby when i try to insert default text into an input text field using the "value" attribute it gets deleted. I was thinking to force insert the text in there when the page load with javascript but not sure exactly how...
<p><input name="vericode" id="vericode" value="This text doesn't display!!" type="text" onclick="value=''"/></p>
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've a text box and a database table entry corresponding to the element. Now, I want to show suggestions as users keep on typing in the text box, the matching words from the database, similar to displaying friends as in facebook search.
I'm building a template editor and changing some of the variables.
Part 1.
Only at DEALERNAME. Must present coupon at time of write-up. Cannot be combined with any other offer. 1 coupon per customer per transaction. Expires: 00/00/00.s
I need to be able to fill out two fields to change DEALERNAME and 00/00/00. I found a way to do this but it required the output to be in a field. I need it the output to look no different than before.
Part 2.
I'm using this to change some text via radio button but I would like an option to select how many details are there is the first place. Say they only want 1 or 2 details and not 3.
Head <script language="javascript" type="text/javascript"> function detail1a(){ document.getElementById("detail1").innerHTML = "Up to 5 Quarts"; }
I have tryid to search for this, but apparently, I cant get the right words for it... What I want is to have an input field (Email) with the word "Email" predefined in it as value, but when a user clicks inside the field, the word disappear and he can write his own email...
My database saves the cars make and model to the row in the database. On the "Add a Job" page, you have to enter the make and model of the car in by hand. I'm looking for a way to have these in a dropdown list, but if the make/model isn't in the list to be able to add it manually.
I can get the makes and models form the database and get them to fill a dropdown list, but then there isn't any provision for entering a make/model manually without going into PHPMyAdmin.
i figured this would probably be best done in JavaScript, but can't find any info on scriptsearch, hotscripts, etc
I've been doing a lot of googling and im having touble finding information on how to do the following.I have an input field: $("#my_field")Which contains the following following text: |1||4||9||10|When the user clicks a button i want to check to if : |4| is in $("#my_field").val()I can find examples on how to check all input fields, however i only want to check the one.
When a string of text is doubleclicked, the text changes into an input field, (dropdown, text, etc), and when the user presses enter or clicks out of the field, whatever they chose/typed in replaces the original string of text.
Quote: <script type="text/javascript"> function emptyTitle() { if (document.getElementById('title').value=='Enter the Title for Your Post') {[code]......
However, the text that appears is black. How do I style it to make it gray and smaller?
