Creating And Writing Variable To Form Input Field
Apr 10, 2011
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 have this code that I want to make it so that it's not inline javascript but my javascript skills are completely lacking. Could anyone spare a minute to walk me through it?
As you can see I am simply creating a place holder for the input field, so that it says "Search" inside of it until someone clicks it. Unfortunately I have very little experience not inlining my Javascript.

I want to create fileds on my form that can not be manually edited
through the UI of the form. Instead the (visible) content is changed
through changes on other parts of the form.
e.g. making a selection from a list changes the content of the field
mentioned above. I don't know the html code to create such a field on my form. Can
anyone help me out?

I have a form that collects information about up to 5 items. I would
like the user to be able to select from a drop down menu how many items
for which they want to compare information, and then have the form
change the number of input fields accordingly.
In other words, if the user selects enter info for 3 items, then input
fields for only 3 items are shown, if they change it to 4 items, then a
fourth column shows up in the table with the appropriate input fields.

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 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 am new to JS and usually learn by studying code posted online and modify it to have it do what I need. Recently, I used a totaling plugin for an online ordering form which does the below:
item1 qty(user input text) * preset price = total price
item2 qty(user input text) * preset price = total price
item3 qty(user input text) * preset price = total price

I have a function that generates the code I want from form input.
Beneath the form I want to create a div tag and write out the results from the form input.
How would I go about doing this?
How would I go about passing the results from the function (e.g. function newCode() {.......(code)... var scroll = X }
Then I want to write out X in a div tag?

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.
What can I do to find the %"#¤ Group Separator??

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:
<a href="javascript: my_function(this.form)"> ... </a>
Problem is, with this code, the form reference isn't passed to the javascript function. the "this.form" bit doesn't work...
I find this rather curious. So the question is, how do I pass a reference to the current form from within a non input field?

I was wondering if there was a way to dynamically read a field input and respond to it later in the form. My situation is this: I have a question that asks how many workers are employed at a business. Later in the form, the user is asked to add as many workers as they have (section with information on each worker) ..Is there a way I can have something echoed or document.write above the latter section saying "Please add (Number of workers listed above) sections for each worker employed"

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.
