In a form I have an input field. It's supposed to get input form a
scanning device. Thus, the input might contain special characters (like
the Group Separator in a EAN barcode). Now, I want to manipulate a
little with the input in a javascript, but I'm not able to find the
Group Separator:
input = document.main.input.value;
var a = input.split("");
var i;
for(i=0;i<a.length;i++) {
if(/x1D/.test(a[i])) {
alert("GS");
}
}
This is a snip that parses the input, character by character, and gives
me an alert if the Group Separator (Hex: 1D) is found. But it never
matches, even if I know that the input string contains in. I have a
similar script written in Perl, an that script finds the Group Separtor.
I've have a function to take the value entered in a form text box, add 50 to it and put the result in another text box.
When I enter 650.5 I get 700.5 exactly how I'd expect. But when I enter -650.5 instead of getting -600.5 I get -650.050 as though it is failing to parse the float due to it being negative. My understanding of parseFloat was that it recognises negative numbers. Is there a nice simple way to get this to work?
I need to pass user input from a form to one database field. I'm relatively new to JS but the idea I had was to have several form elements and use JS to collect the users input and send all the values through a hidden element. What's happening is the variable names are being sent rather than the values. The code below is only passing to the next page. Limitations: I am editing an intranet site built by a 3rd party so a lot of the files we've been given are encrypted. I cannot change the method to post.
I've been searching for a few hours and haven't been able to find a code snippet to see if this is available. I'm attempting to pass text from my website to another website that has a form setup on it. I'd like to fill in the pertinent data for my users on the page that I load for them. I cannot make any changes to the receiving page as it is run by another company. I've pasted some of the code that is available on the receiving form.
<script type="text/javascript"> //<![CDATA[ var theForm = document.forms['form1']; if (!theForm) {
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 have this script where i call a jquery ajax to calclate something and then put it back in the form input so then i post everything to a php script where it insert it in mysql database. Here is the script :
I have a bunch of forms in my page, and want to pass a reference to the current form to a javascript function - when, say, a user clicks on a particular element. Normally, within any type of input field, I'd just add something like this:
onclick="my_function(this.form)"
Then, in my_function( form ) I could refer to form. No worries.
But here's the interesting bit. I also want to run the same function when the user clicks on any <a> tag within a form, like:
New to working with javascript and I've come up with a function. I have a form with a dropdown and input field: <form> <select name="warranty" id="warranty" onChange="doadate()"> <option value="Select">Select</option> <option value="In Warranty">In Warranty</option> <option value="Out of Warranty">Out of Warranty</option> <option value="DOA" selected>DOA</option> </select> <input name="doadate" type="text" id="doadate" value="<? echo $doadate; ?>" size="20" readonly> </form>
I need the input field to be disabled unless DOA is selected in the select form element. I've started on page load with document.form1.doadate.disabled=true. Then I've put an onChange handler in the select to call the function below: <script type="text/javascript"> function doadate(){ val = document.form1.warranty.value; if(val=='DOA'){ document.form1.doadate.disabled=false; } else{ document.form1.doadate.disabled=true; }} </script> But it's not working, it stays disabled after load even when the DOA is selected in the drop down form field.
I need to show the date picker in an input field that is inside a form. I have index.php which has the code for the date picker, I just need to link it to the input field. I have the form in another file as follows:
Tried searching but didn't seem to find a solid solution to my problem I'm trying to pass a value to an input form field, from a function. Here is my code
PHP Code: <script> function createDiv(sceneNum, startTime, endTime, dialog, notes)
I am working on a javascript for my blackberry. I am trying to capture the latitude and longitude of that phone. I am able to get the coordinates in an alert box but am having a little trouble writing it to a form input field.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "[URL]"> <html xmlns="[URL]" xml:lang="en" lang="en"> <head><title>GPS Testing</title> </head><body> <script type="text/javascript"> if(blackberry.location.GPSSupported){ document.write("Your device supports GPS locating"); blackberry.location.onLocationUpdate(window.alert("Latitude: " + blackberry.location.latitude + " Longitude: " + blackberry.location.longitude)); var lat = blackberry.location.latitude(); var lng = blackberry.location.longitude(); blackberry.location.refreshLocation(); document.write(lat); } </script></body></html>
I am only able to test with Blackberry. I was trying to create a couple of variables with the "var lat =" and var lng =". With this script I get the alert window and when I click ok it writes "Your device supports ...".
I want to bypass from one input field to other one by <enter> (<return>) key pressing instead of default behaviour (<tab> key pressing).But there was default form action on <enter> keydown event was performed. Remember that <enter> keydown event on form means default "Form submit" action. How to prevent default action, form submission, in time of <enter> keydown event processing?
How to modify following code? I use hotkeys jQuery plugin for key binding to input fields.
$().ready(function(){ $(myInputFieldsSelector).bind('keydown','return',function(evt){ //find next input field in the form MyNextInput MyNextInput.focus().select();
I'm developing am income tax calculator, and everything is going swell. Currently the user can type in their adjusted gross income (AGI), hit submit, and learn the amount of income tax they would pay, their tax rate, and their income after tax.
I've played around with the events to get the submit button to work in FF, IE, Chrome and Safari -- and I've gotten the enter button to work before with some stock code, but here's the catch: when the user presses enter, i want the focus to leave the input box. I don't care where it goes (submit button, I suppose?) but i need it to leave the input field so the onfocus="clearText(this);" event can fire when they return to type in a new income.
<script language="javascript" type="text/javascript"> function TotalGrossPerYear() { var Calc = document.NetIncome; if (Calc.InputRad[0].checked) {
I have a small piece of code (taken largely from W3 Schools)that checks that there is a decimal point entered in a form field, but what I really need is to check that the number entered ends in 2 decimal places.
e.g. 10 is Invalid 10.00 is Valid
My current code is below. Can someone explain what I need to do to ensure that the user enters a number including two trailing decimal places please?
How do I change the background colour of an input box in a form as soon as the value is changed? Also the background should revert back to it's original colour if the user decides that they do not want to make any changes and hence retype back the orginial value.
I do not want the background to change after the user has moved to the next form field but as soon as the value has been changed.

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.
