Capture When A Textbox Has Changed!
Jul 23, 2005
Does anybody of you have a good algorithm to capture when a value in a
textbox is changed? I'm using the keypress/keydown events but they seems to
be a bit inconsistent (IE and Mozilla). Basically what I want is to set is a
"isDirty" flag when a user has changed any value in the textbox (or in a
dropdown) and then if he/she tries to leave the record without saving I want
to give a save warning. Since I don't want set the isdirty flag if you for
example klick tab, certain F-buttons, arrows (up/down/left/right) etc I
tried to capture the keypress/keydown event and ignore specific keycodes.
Since there are several keycodes that should be ignored I was hoping there
is a better solution.

Below is the script and form fields I am working with. What I want to do is sum the two textbox fields and have the result show in the total textbox. The code works fine and the total textbox is updated with the value of form1.basic. The problem occurs when I add the "+ parseInt(document.form2.supporter.value)" code in the script section.

<script type="text/javascript">
$(function () {
$('input[id *=txtAmt]').blur(function () {
var txtBoxThatChanged = $('How do i get a reference to the textbox that changed?');
[Code]....
In my grid each row has a twin row (not consecutive) the rows each have 1 text box with a name containing txtAmt. When a user enters a value in the text box in a row. I need to put that value in the text box in the twin row. i got the blur function to work on each text box but do not know how to do the rest. I typed a description of the selector in each $().

I have two textbox columnsof equal length they are accessed in the following manner:
taborder 1
taborder 2 taborder 3 taborder 4 taborder 5 taborder 6 taborder 7 taborder 8
When I leave the first textbox (taborder 1), I need to check and see if the textbox contains avalue. If it does, then I need to check and see if the second textbox (taborder 2)contains a value. If it doesNOT, then I need to loadthe second textboxwith "100" and highlight (select) the text. I am adding a blur event to all the column one textboxes as they all contain"rawCount" in the id. Here is my blur event code:
$(document).ready(function(){
$('input[id*=rawCount]').bind('blur', function (event) {
// Code to go here
});
});
What I am trying to do isadd thecode tocheck and update thecolumn two textbox in the corresponding row (same index)to the blur event of the column one textboxes without having to loop the array each time to find the current textbox array position. Since it is adding the blur event, it has to be possible.

I am doing a lottery project in which i have 10 textbox and i want to add contents of each textbox and show result in another textbox say 11th textbox.
I am having the fallowing codes below on jsp page.
I want to add contents of textbox from(n50,n51.....n59) and show result in another textbox named (n60)
My question is that the valus stored in textbox is numeric and when i enter the value in any two of the textbox say named (n50 and n51) then the addition of its value must be seen in the result textbox say (n60) here. it does not wait for another textbox value which is left blank. the result of addition should be displayed simelteneously as i enter the value in text box.

How do you detect that a form element has been changed? This thread:
http://groups.google.com/group/comp...25a82c9be127790
suggests that you attach onChange event handlers to every form element,
and when the handler fires you update a global 'isChanged' variable.
This technique seems to be a bit messy to me (I have many form
elements), I was thinking about storing the original form object in a
javascript variable when the body loads (in the bodie's onLoad event
handler), and upons submission, doing a javascript equality comparison
with the current form object. If nothing has changed, then the two
objects should be equal, right?
if(oldObject == document.getElementById('form'))
{
alert('has changed!');
}
Would this work?

After fetching a timestamp via sql,I return to javascript to do the formatting. Actually, I was first doing a bit of formatting in php to change from yyyy mm dd hh:mm (as saved in db) to mm dd yyyy hh:mm as I found the 1st not to work with the Date() function in FF.Consider the following...
var date_from_server = "06 03 2009 01:37";
var jsDate = Date(date_from_server);
In FF jsDate is "Thu Jun 03 1909 01:37:00 GMT-0700 (Pacific Daylight Time)".In IE7 jsDate is NaN.I've tried a few different formats. Does IE7,s Date() function not allow an arg at all or only of a certain format?

I have a form where users need to be able to change a particular value in a <select> but need to confirm that this is what they want to do under certain circumstances. I have the script firing up ok and prompting the user, but I'm darned if I can figure out how to undo the change if required.
What I want to do is something like document.form.object.value=document.form.object.oldvalue but I have no idea what the correct properties are.....
So, how do you roll-back the selection in a <select>?

window.opener.img<%=rowid%>.src = "this.jpg";
window.opener.col<%=rowid%>.innerHTML=strReturn;
window.opener.row<%=rowid%>.style.display = "inline";
The innerHTML and style.display of the above works. Both col?? and row?? can be targeted and changed. However the img?? does not work. The ID on the tag is fine but the image wont change. Incase it was src I tried with style.display too on the image but still wont target it.

I've got a web site that is frequently updated; yesterday several
subscribers contacted me to say they couldn't see the update. I suspect
this is a cache problem, so is there a way to force a page to be
reloaded when it is changed. I realize it is too late for the current
pages, but I'd like to include something later.

[code]I am having a hard time coming up with jquery code to have it so if I rollover something in .list that it will change the background image in #column2.I am thinking that building an array of IDs and IMAGELOCs would do the trick. Basically the PHP is going to give me IDs and Image Locations.I am just not sure the best way to write the jquery (cleanly) to perform the functions I want. I also want it so when you click the LI that the ID number that matches the DIV inside of #column2 will be shown.I understand jquery on a "copy & paste & modify" basis but having a hard time utilizing FORs and such.

Trying to construct a sql statement to update field values contained in a form. I would like to only update the values that are changed. If the current $_POST[] values populated in the form are not changed, there is no need to add that field to the UPDATE statement... but i am not sure how to do this with javascript and pass only those values. Can someone help?
Some say that it is not worth the code processing to do this but I would like to do this if possible. I know that phpmyadmin works this way.
