Check If First 2 Letters Equal Certain Characters In Input Field?
Jun 14, 2011
I am having trouble with some javascript code that checks the first 2 letters of what the user inputs and whether it equals a certain set of characters. If the user for instance types in 'TT' in an input field, then i want the holding div to disappear, if anything else is typed in then this action wont happen. My code is below:
Code:
<script type="text/javascript">
function checkCode() {
var x=document.forms["myform"]["code"].value.substring(0, 2);
if (x == 'TT')
[Code]...
I believe the problem lies in the javascript line: "if (x == 'TT')", as the rest of the script responds but it just doesnt recognise whether 'x' starts with 'TT'
I have already done a number of things with Jörn's validation plugin and I'm excited about its features. But here is my question: how do I validate a field so that it fits the two following conditions: it should be an integer and should not be equal to zero? So, if a user enters "0", it should be error; if he/she enters "12.5", it should be error also; but "-3", "125", "40" are OK.
I have a draggable marker on my page that sets the value of a javascript variable when the marker is released.I want to submit this value to store it in a database however I cannot figure out how to pass this javascript variable as a hidden form field.Here is my code. I suspect this is completelyhow to make this "lat" value available to me after the form has been submitted.
I am doing some basic form validation stuff and I have two fields (phone, fax) that I need to check if the characters enterred are numeric, but still allow + and () characters to be enterred. If anything else has been enterred to display an error message.
Can someone point me to a resource ( I searched, but couldn't find an obvious one!) or give me a rundown on some code here to help me out?
I have an email which has some values attached to a link in the email that get passed to an online form on a website when clicked. Problem is the value is a price and the string includes a "$" which I need to remove. I've read through many examples and everyone seems to have an opinion (surprise). One suggests something like this: text2.value=text1.value.replace(/$/g,""); While someone else says its better to remove what you don't want. I am also scratching my head over should I place the value into a hidden field, scrub it then copy that into the proper field? and I imagine the best way would be to run it with an "onload" command instead or a event handler like a keystroke since the field is not typed?
I wanted to try creating a basic expression first. I want someone to enter a string that is 2 - 20 characters long and only has letters. This is what I use so far, and it doesn't work, nothing happens at all when I run it.
Code: // Check for a valid name. var namePattern = new RegExp("/^[a-zA-Z]{2,20}$/"); if (namePattern.test(name)) { window.alert("Invalid"); }
name comes from a input box I display on screen. Also, I would like to update the expression so that there can be one space in the string, but it cannot be at the beginning or end. So this string is like a persons name. Bob is OK, Bob Smith is also OK. Edit: Actually, it is doing something but its always coming back invalid.
I would like to disable a feature on my site if someone is in a textarea or input text field. Yet I can't seem to figure out how to check for this... Could someone give me an example of how I can determine if a user does not have a text input or textarea selected? Can't seem to get anything I found via google working.
I'm working on a script to check password strength "onkeyup",so when the user enters a password after every character i call a function to check the passwords strength.I'm almost ready,but i stucked with one thing:I want to check the same characters in the password,so i can deduct some point from the score if there are identical characters.Here is my code:
var multis = 0; for(var x = 1; x < passLength; x++) {
im wanting to add check boxes up to create a total sum at bottom of the form or anywhere for that matter.im wanting to add the values up of the check boxes and then the total amount of checked boxes appears in the total amount. also ive been trying to get it when you uncheck a box the amount goes away from the total amount.here is what ive got
<script type="text/javascript"> function initialize(){ Total = 0;
I am having problems with the code below (obviously) coming up with illegal character for various characters within the field name which is: S_Gift Finder1_0
I have tried various ways of escaping the characters but to no avail.
I am unable to change the name of the field as it it comes from an external off-the-shelf package. Code ....
And my question is how to make it display error if I have entered letters in the age box or numbers in a name box? Currently I have only if it is different from 1, so what should I write instead of 1 ?
i want a value search(find) to database(table), this requires an ajax call to a server page? if want show result search live(online) and search letters to letters (transliteration), how is it?
I keep getting <undefined> when I alert out the value of my array 'fadeimages1'. Using php/mysql I retrieve filenames from a directory and create <INPUT> fields to store the filenames. In the javascript portion of the code, I use getElementsByName() to retrieve all of the <INPUT> fields. I then declare an array, 'fadeimages1'. Next, using a for loop I try to copy the values from the <INPUT> fields into the array 'fadeimages1'. When I alert out the length and value variable for each <INPUT> field, I get the correct filename, but after trying to store the value into 'fadeimages1' array, I get value is <undefined> when I alert it out. BTW, the following code uses 'fadeimages1.push()', but I also tried 'fadeimages1[i]=...'. Both result in <undefined> values.
Heres my javascript code that will verify email from email input field and check if the checkbox (I agree condition) was checked:
[Code]....
However, this will work fine when calling with a link "javascript:validate('inputForm');" but if I try to prevent users by submitting form with pressing enter I put it in form onSubmit parameter: <form .. onSubmit="javascript:validate('inputForm');"> which will check the forms and submit data (do return) no matter if it matched or no.
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.
i don't know how to check for illegal characters for name.. i have one for username but i don't understand how to use it.. it does not allow spaces so it will not work for first and last names..
am doing a check on my fields, so that they only contain certain characters and numbers. var validEntry = /^[a-zA-Z0-9@$&"]+/; but this also captures a space in between words as an error. can somebody please tell me on how to avoid this.
Ive got a project and ive been steaming ahead with it myself for a bit, i was given the code to start off with but have adapted it for my own needs. As well as fieldOne being a minimum of 3 characters I also need to check if the first three characters are the same because we get a lot of spam.
i am trying to check a character with another character which are in the same text box.when we are entering date,date in the first text box and month in another text box and year in another text box.now i want when i am trying to enter '0'in the character position when there is '0' at first character position it must raise an alert box as well as when i am trying to enter a digit greater than '1' at 2nd character position it must raise an alert box when there is '3' in the first character position.
