Formatting Auto-computed OnChange Field To 3 Decimals?
Dec 13, 2010
I have some fields on my form that are auto-populating with a difference from 2 input fields using onChange, easy stuff. The correct value is stored in the DB, to 3 decimal places (correct, since data type is a float with 3 decimals).The challenge I am having is to get the number that is auto-displaying on the form to format to 3 decimals. For example, when I enter the first number at 44.8, and a second number of 44.666, the onChange command displays '0.13400000000000034'. This is saved in the db correctly as, '0.134' and once the form is submitted the correct value of 0.134 displays since it is pulling directly from the db. I would like to format the onChange display with the toFixed command so the extra decimals don't show onChange.

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.

I'm using Google Maps to calculate distance between cities. I need to use that distance value for some basic calculations. Distance has to be in "Angloamerican" format (1,234.00) but in metric system. So, Google Maps answer for Madrid - Berlin query will be one of these two:
a) <span jscontent="distance['text']" jsdisplay="distance" jstcache="7">2.320,1 km</span>
b) <span jscontent="distance.text" jstcache="23">2.320,1 km</span>
notice the differences in span "classes" (jstcache is 7 or 23) and lack of any "id" or "name" attributes.
What I want to accomplish is:
1) Convert these Google Maps distance values to "Angloamerican" format (2,320 km) or (even better) format without thousands separator which would only use dots as decimal separator (2320.1 km)
2) Use that filtered value to populate a text field called distance
Populate hidden form element value with the value of a text field on form submit (jQuery)
It helped me a bit with the auto-populate part, but I can't make it work in combination with this Google Maps code. Here is my current code:
<head>
...
<script type="text/javascript">
function submitMyForm(){

I have a website which uses several forms to input data, each form contains fields for the user to complete and at the end of the each form the user has the option to proceed or go back.The problem is, on form1 there is a drop down box which determines the content of subsequent forms but when a user partially completes form2 but then goes back to form1 and changes the drop down box selection, the onchange function reloads the subsequent forms but it does not clear the previous form2 values so an error is generated because those inputs are not required with the change made to the drop down box. I have tried setting the ids to zero using getelementbyid on form1 but it does not seem to work presumably because the ids are on form2 not form1?

Have an asp.net form where the textboxes have had the onblur attribute added. Though VS2008 still barks it's an invalid attribute...However, my problem is primarily w/the txtFICODate field.When testing using 10/10/2009 in this field, the code displays the appropriate msg based on format param. However, on exiting the isValidDate function in debug mode, I see that the code does not stop at the txtFICODate html but moves to the txtDOBB isValidDate function. Here the param is MM/DD/YYYY and it loops back into the function but now displays a different format message.Previous code (ValidateFICODate(obj)) below also caused the same looping error.
Debugging the same code with the txtDOBB field (10/10/56), I see it enter the function, display the appropriate message and exit. However, in debug, the code comes back to the function and then selects the field contents.how to fix problem so code stops at the txtFICODate field .Using xp Pro SP3, visual studio 2008 (c#).in the process of writing this, I searched other post here related to onblur + loop. So changed the event to onchange...and while the looping does not now occur, the focus just moves to the next field.
On page load code(if (!isPostBack)):
txtFICODate.Attributes.Add("onblur", "isValidDate(this, 'MM/DD/YY');");
txtDOBB.Attributes.Add("onblur", "isValidDate(this, 'MM/DD/YYYY');");

i have 2 nested divs like this:
<div id="outer" style="display:block;">
<id ="inner">
<input type ="text" id="txt"/>
</div>
</div>
in my javascript, when i alert the value of (document.getelementbyId('inner')).style.display, I get blank value. when i do the same for outer div, then i get value block. however inner div is inheriting style from its parent. i need to add some specific handling in case style of inner div is block, whether explicit style or computed style. i cannot do the check on its parent's style as it might not always be immediate parent.

In my program, I have GMap logic that outputs location information to
a disabled input field (was previously a label). Then, when a
user clicks on a link (to start a new map), I want to save the location
data to an array prior to server processing. So, onchange, save the
input field's value to array[last_click]. But, because this field is
hidden (or readonly) I am not sure how to go about this.

I have a form where I need to populate a field with a math equation using inputs in the form. Here's the example:
fieldA fieldB fieldC ... fieldJ
fieldX
As the user inputs a number in fieldA, I need fieldX to immediately change and display the average of fieldA - fieldJ if the field is not empty (valid entry for all field's is a number between 20 - 80). I don't have the ability to make many changes in the form because I'm using a product called Gravity Forms for Wordpress.

I want to add an event to a generated SELECT field. It's an onChange call to a function named calculateSubtotal(). The result I want would look like <select name="..." id="..." onChange="calculateSubtotal()">.
This is what I've got so far. The drop menu is created with no error, but no onChange either. Code:
var newTour = document.createElement('SELECT');
newTour.name = 'registour' + rowCount;
newTour.id = 'registour' + rowCount;
var newAttrib = document.createTextNode('onChange="calculateSubtotal()"');
addOption(newTour, '');
addOption(newTour, 'Tour 1');
addOption(newTour, 'Tour 2');
addOption(newTour, 'Tour 3');
document.getElementById('groupreg').appendChild(newTour);
document.getElementById(newTour.id).appendChild(newAttrib);
I also tried this, it doesn't work either:
newTour.onchange = 'calculateSubtotal()'

How do I set focus on the next textfield in form when there are two characters typed in the textfield before. Like entering serialcodes for installation, you can just keep typing and the characters will appear in the next textfield when the textfield before is full.

Does anyone have a thought on how to code an auto tab feature for a form? I have a form that has a telephone number which is broken down into three boxes (area code, first three numbers and last four numbers). I want to be able to tab into the next box automatically when I hit the correct amount of numbers for the field.
Conceptually I know how to do this, but I do not know JS very well (yet...) so I have hit a bit of a wall trying to figure it out.

I have a requirement in which, I need to capture a loan amount and the amount of down payment for that loan. According to the requirement, the user is going to enter enter the loan amount and then will enter the down payment in either percentage of the loan amount or an actual amount. I have designed a form to capture this information with three text fields, one each for loan amount, down payment in % and down payment in $.
So the user has the option of entering downpayment in $ or in %. If the user enter the down payment in $ then my code has to calculate the equivalent % value and populate the corresponding text field and vice versa. My question here is, what would be the best way to handle this
situation.
Shall i just use the OnChange event of the text field to handle this scenario? If I do that wont I be running into a loop?

I searched here and some other places on the net but cant find anything that suits my needs. I have a SELECT box with 3 values Code:
<form name="form1">
<select name="length">
<option name="length" value="none">--Select for All--</option>
<option name="length" value="5">--5 Days--</option>
<option name="length" value="7">--7 Days--</option>
<option name="length" value="10">--10 Days--</option>
</select>
</form>
OnChange, I want to invoke a function that auto populates the rest of the SELECT fields in the form. The select boxes will vary in quantity as the page is dynamic, but the values are always the same (like the code above).
Does this make sense?

I know that I cannot specify the zIndex of a relatively positioned div BUT it does have a zindex computed by the browser. That's why another div can appear below or above it. So, how do I figure out what it's zindex is so I can dynamically put something above it?
Using .currentStyle/getcomputedstyle doesn't work as it returns "auto".

I have a simple form that contains an INPUT element that has an initial value.
<form name="Form">
<input name="Number" type="text" value="Hello">
</form>
When the form loads, I want all of the text in the field to be automatically selected. How can I do this?
Doing a:
document.Form.Number.select();
selects the INPUT element itself, not the text inside of it.

I have an HTC (Thanks to Beetle) that auto fills a field as a user key strokes letters into a text box. Except for one thing everything works great. The one thing is if a use types somethin in that is found, accepts it (tabs out of the field) the goes back to the first letter and trys to change the case (upper to lower or vise versa) it gets an error "invalid argument". I cannot seem to figure out why it would error. Below I have all of the code HTML and HTC should be easy Code:

I have a text field on my page, whose value I am setting through the jQuery cal
$('#Expandable').val("fefefe");
However, when I normally type into the text field, certain events occur as the text field value changes. These events do not occur when I set the value like above. So my question is, after I set the value, how do I invoke any onChange handlers?

I am trying to create an anonymous function for onchange event of file field, so that when a file is selected, the covering text field gets that value. I know how to accomplish this by adding onchange="", but I'd prefer not do that. The code that I have almost works, except that the function in the for loop can't call on the "i" variable that the loop uses.
for( i = 0; i < source.length; i++) {
source[i].onchange = function() {
name[i].value = this.value;
}
}
