Table Row OnClick Functionality Lost
Nov 6, 2010
I have been using a tr onclick function in my tables to change the color of the most recently clicked row, it works fine. I have recently added sorttable [URL] to my table with the simple
<table class="sortable">
Making the table sortable has overwritten my tr onclick functions, which are now dead.
Heres a quick sample of what it looks like:
<table class="sortable">
<thead><th scope="col">Header 1</th>
<th scope="col">Header 2</th></thead>
<tr onclick="doSomething(this);"><td>Some data</td><td>Some more</td></tr>
</table>

I was having no problems at all testing at home (FF, in private mode to keep cache clear, and error console to check... also Opera and Safari) when I suddenly lost functionality on several jQuery functions, all of them similarly structured. Couldn't find the problem; updated jQuery; stripped the codes back to one particular function; still no clue.
So: now the puzzle isonline.
The calls to load the elements in the page are in the <body> tag.
These capabilities work correctly: resizing, scrolling with arrows, popup from underlined link, dragging. What doesn't work is what should happen when you hover on any of the six-line figures: You should see a number underneath and on click, a change of color, and new text on the left.
Script file: hover is at line 100; the click function at line 78. The calls for the click function are here:
Testing again online, Opera (mac) now functions correctly. So, I think it may be something to do loading. I've put a delay to make sure the elements to be operated on are loaded before the functions which do the operating. Still no dice. It also seems to load really slowly, but that's minor at this point.

*The Situation*
A traditional situation where HTML form inputs are checked...
(if simplified then it would look something like this)
<form onSubmit="return checkWholeForm(this)">
<!-- other inputs -->
<input type="text" name="anInput" onBlur="dataCheck(this, ...)" />
<span id="error_anInput"></span>
<!-- other inputs -->
<input type="submit" name="btnSubmit" />
</form>
dataCheck validates the inputs value and if something is wrong, then..
document.getElementById('error_anInput').innerHTML = 'Error!'
or if data is valid then the content of span is removed.
The checkWholeForm function iterates through all elements on the form
and triggers onblur() for each input... leading to executing function
dataCheck (and so changing innerHTML of some specific span elements if
needed).
*The Problem*
If I have entered incorrect data to an input and hit the submit button
with my mouse (causing the onBlur event to be triggered just right
before onSubmit) then *occasionally* for some fields the onSubmit event
is not triggered because the onClick event is not triggered. :S
As there are actually quite many complex functions (tested and these
seem OK afaik) that are doing the checks then dowes anyboudy have a clue
what type of code might break this. I thought at first that setting
innerHTML to some value during onBlur disables all waiting events but as
this is happening occasionally (on some machines) I'm in doubt...
any ideas what to check? double declaration of function/variable names?
Not deleting some object after usage? ... anything?
Waiting for any ideas...
PS. http://eix.lap.ee/test/portali_js.html in the example *occasionally*
third field generates the error - remove any content from the field
and stright hit the submit (*with mouse* - to create onBlur and onClick
at the same time).

I am in the process of creating a billboard script for our company front page which will switch between two images. I am using the following script as a base: [URL]
I am eager to learn coding, but am still a novice at it so I was wondering if anyone could assist me with adding the following functionality:
1. Rather than (or perhaps in addition to) having the two images change based on a timer, I'd like to be able to insert a "next" arrow. Therefore I will need assistance in coding a button to change the images from "ad_1" to "ad_2" which is currently done automatically by the interval timer
2. I'd like to make the images clickable with unique destinations (so when you click on "ad_1" it will take you to "link 1", "ad_2" will take you to "link 2"
Below is my current code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
[Code]....
And here is a working example: [URL]

I am trying to add functionality to a table that allows users to add and remove table rows, but I am stuck on the JS part of it. The JS I am working with allows users to add/remove table rows that are populated with text input fields, but I want it so where the rows are populated with these elements: 1) multiple select with populated options, 2) file upload box (input type="file"). How to modify the JS below to do this (I am new to JS).
Here is the JS I am working with:
Code:
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var cell1 = row.insertCell(0);
var element1 = document.createElement("input");
element1.type = "checkbox";
cell1.appendChild(element1); .....

I have table with many rows indicating my record. I want my rows to
load my record, so I attached an onClick event to every row that loads
the proper record. Now, there are options associated to every record
(delete link, select checkbox, etc) that don't result in loading the
record. The problem should be obvious, upon the user clicking on any of
those options, the row's onclick is triggered which is undesirable
behaviour.

I need to make a table fadeout with JavaScript when I click a button. [code]...
There is a button that calls a function called fadeout(). I cannot find a way to make the table fade out with just that one function.

I'm trying to create a dynamic table with onclick event like this but onclick event seems to do nothing:
var srcTable = this.iContext.getElementById("tbody");
var tmpRow = null;
var tmpCell = null;[code]...
I found a few examples like this: tmpRow.onclick = function() { alert(this.rowIndex);};
but I need use selected data, maybe call a defined function. I already tried lines bellow but nothing works, because doSomething is not function of tmpRow object.
tmpRow.onclick = function() { doSomething(this);}; or tmpRow.onclick = doSomething(this); or
tmpRow.onclick = "doSomething(this)";

I am trying to get the value of a table cell that is generated by a php loop. The purpose is so eventually I can click a row out of a list and have it take me to a form view of the list item that is clicked. I've searched and searched for the last few days for something with no luck. I run across a lot of hits that tell me I need to have an id for everysingle thing I click on but there has to be a better way.
Code:
function test() {
var elTableRow = document.getElementById("tr");

I have a php page that essentially builds a pay report in the form of a table. The php side builds the page properly, though it took some time to get the table rows onmouseover and onmouseout functions to work for row highlighting. Now the issue is the table row's onclick function.
Here is what the outputed html looks like.
<head><script type="text/javascript" language="javascript">
function HideShowDiv(divID){
if (document.getElementById(divID).style.display == "none"){
document.getElementById(divID).style.display = "block");
document.writeln("show "+divID);
}else{
document.getElementById(divID).style.display = "none";
document.writeln("hide "+divID);
}} .....
<tr>
<td colspan="2" align="right">Some Association of Baseball</td>
<td align="right">$24</td>
<td align="center"></td>
</tr>
</table>
</div> <!-- Closes the main body div container -->
In my javascript function, the writeln() calls are for testing to see if the even is even firing. but nothing gets written to the page. Basically I want the row with the users name to be clickable which will show the details in the hidden div associated with the user.

The code below assigns a value to the Latitude and to the Longitude table cells when the submit button is pressed. I would like to have these values appear in text boxes instead. Obviously I need to amend onclick="javascript:usePointFromPostcode(document.getElementById('postcode').value, placeMarkerAtPoint)"
to make this work but I can't seem to. Assuming two text boxes with names lng and lat, how would I amend the line?
Code:
<p align="left">
<table bgcolor="#FFFFCC" width="300">
<tr><td width="100">
<b>Latitude</b></td>
<td id="lat">

<tr><td width="100"> .....

I have this table with alternate row colors. Class gray and class
white. I have javascript that do highlight when mouseover row ... and
onclick to select row and highlight it with another color. Also created
a class called "Selected". You can only select a row at a time.
My problem is, if a row is preselected, when mouseover the selected
row, the selected color is screwed. Until you click on the selected row
once, the behaviour is correct again. Code:

I have a wapper here, and I'm going crossed eyed trying to figure this one out. I have a form with Radio Buttons for my customers to purchase a customizable club program. I have 5 sections each of which cost a certain amount. Then I have another section that lets the user pick what duration they would like, 3, 6, 9 and 12 months. Each option has a certain % taken off the retail price. 5%, 10%, 15%, 20% depending on the duration option. All calculations are done on the fly as customers click the radio buttons. I do have it set up and working, only I have the duration listed as many times as my sections. I would like to have only one duration section. I'm not sure if this is done in java or HTML....

I've got multiple xmlhttprequests which are in a loop. So this is the
loop I have so far, with the closure given to me in a previous post:
//-------------------------------------------------------------------------------------
for (i=0; i<data.length; i++) {
httpRequest[i] = false;
httpRequest[i] = new XMLHttpRequest();
httpRequest[i].onreadystatechange = function(index) {
return function () {
if (httpRequest[index].readyState == 4) {
if (httpRequest[index].status == 200) {
var stats = getStats(httpRequest[index].responseText,
data[index]);
updateStats(statsTable.rows[index], stats);
}
}
};
}(i);
httpRequest[i].open('GET', URL, true);
httpRequest[i].send(null);
}
//-------------------------------------------------------------------------------------
So basically, the getStats method parses the response to get the info
I need for that particular request and then updates the html of the
current page accordingly. This works fine for 1, 2, or 3 data
requests. But if I have more, some of the httprequests get lost and
not all parts of my page are updated. But, if I throw in an alert in
each loop, all page data or at least more of them are updated, once
per time after each loop. It's like the alerts slow the loop down and
allow the requests and updates to catch up to the loop processing.
So, I'm not sure what's happening when the alerts aren't there. Are
some of the requests getting clobbered somehow? Are the httprequests
fine, and maybe the original document can only be updated once at a
time?

I am relatively new to js, but I did think I was starting to get the
hang of it. Then this happened...
I have a form with an onsubmit event handler:
<form id="uploadForm" method="post" action="..."
onSubmit="checkDates()">
The event handler does some minor validation, then returns true or
false:
function checkDates(y, m, d) {
if (endDate.getTime() >= startDate.getTime())
return true;
alert("Start date must precede end date");
return false;
}
(The arguments to the function are used when it is called elsewhere,
not as onsubmit.)
I also have a library class which needs to process the form submit, so
it hooks onsubmit like this:
MyClass.setOnSubmit = function(listId) {
var list = document.getElementById(listId);
var form = list.form;
var f = form.onsubmit;
if (typeof f == "function") {
form.oldOnSubmit = f;
form.onsubmit = function(){
var ok = this.oldOnSubmit();
if (ok)
return MyClass.onsubmit(listId);
else
return false;
};
}
else
form.onsubmit = function(){MyClass.onsubmit(listId);};
}
My problem is that the value returned from oldOnSubmit and stored in ok
appears as 'void'. This happens in IE 6 and in FireFox 1.07. Can anyone
explain what's happening?

I have a problem that the window.opener variable is lost once my popup
page has a postback. On multiple pages they address this problem but I
cannot find a correct answer.
This is my situation:
I have a main page which shows invoices. When a user clicks on the
invoices they get a popup where they can alter the invoice which uses
postbacks because of direct changes in the database. Finally the user
can click a button to accept the invoice and then I need to change two
variables on the main page which opened this popup, the new invoice
fee and status (which is based on the button pressed). I dont want any
postbacks on the main page, therefore I simply want to pass these two
variables from the popup to the main page.
However, after a single postback on the popup page the window.opener
variable is gone and lost forever. Now I have seen solutions using
frames but I do not know how to go from there because I also pass some
variables from the main page to the popup.

I have a series of elements on the page that have been assigned anonymous functions as a user works with them. At a certain point I would like to take a element and all of its children and copy them from their current location and into a newly created element. Then remove original version and all its children.
I have done the above by using innerHTML to copy the element and its children to a temp variable.. problem is that I think my copy has lost all these anonymous function that was assigned to the original version. Has anyone ever faces the problem of trying to copy a series of elements and losing their anonymous assigned functions in the copied version? If so whats the work around on this?
