I wanna find out the number of my columns in my table. How can I do that? I have tried to do it with the following code, but it delivers me an "undifined" as result. What's wrong here?
HTML Code:
I'm trying to append <tr> after every x number of <td>'s. I'm not sure how to do it.
Here the code which I'm trying to do.
End result: should be 10rows and 10 columns.

View 1 Replies View RelatedI want to count the characters in a string. The problem here is, the 'return key' i.e if 'enter key' should be counted as 2 instead as 1 character.
I tried few logics but none of them worked out. I tried with php ajax too. It worked fine in firefox but not in IE.
Here is the logic i used. When onkeyup call the js function.. which calls the php page by passing the string as encodeURIComponent(str).
Now, I took the string in php and counted the in the string and added the no of occurrence of to the string length.
My concern is, IE is returning 3 for return key instead of 2.
I want to know how to count to a number via jQuery. jQuery should get a value in a variable and then start counting to it in a fix time. for example the number is 500.67 then i should start with 1 and the add up until it reaches 500.67 in 5 seconds, so the final value is not visible at the begining but at the end. the numbers can b between 1 and about 1 million but it should always need 5 seconds to count to it (must not be always +1 but i should count smooth).
View 2 Replies View RelatedI'm creating a small contextMenu for my website:
// Right click on file
$('.file').live('mousedown', function(event) {
// If rightmouseclick (=3)
if(event.which == 3) {
$(this).bind("contextmenu", function(e) {
e.preventDefault();
});

When I right click on a file and pick "openFile"from the context menu, the action only run once. But when I do this again, it runs twice. When I do this again, it run three times, and so on ... For some reason jQuery (or JavaScript) is counting the times I have clicked on the class '.file', and fires the action according to this number.

I have a piece of Javascript which i'm using to count the number of words in a textbox, which works nicely.
However the text called into that textbox is called dynamically from a database and the amount of words called into that box is ONLY shown when the user clicks on the textbox using onkeyup or I can create it when I use onClick.
is there anyway you can say on page load or something similar rather than having to click a box using onkeyup or onClick?
I have a php page that dynamically generates any number of text boxes.
To validate its input, I need to know how many text boxes are in the form.

I was wondering if anybody can provide me with high level suggestions as to how to do the following in javascript.I want to record the number of times a piece of javascript is run across multiple disparate machines.To do this I was thinking that the javascript should open javascript a webpage every time it is run. I can then count how many times that webpage has been called which in turn will be the number of times the javascipt has run. However I don't want the webpage to open in the users machine as this will be really annoying for the user.if you can think of a better way to complete the overall goal.
View 8 Replies View RelatedI have a requirement to build a div in a page that contains a table of
plane details, and one of the columns (on the left - tail number)
needs to be sticky on the horizontal axis but not on the vertical axis
(i.e. when scrolling right the tail numbers need to stay visible on
the left hand side, but when scrolling down the tail numbers need to
scroll to keep up with the rest of the plane details).
I have been looking at various ways of doing this but currently to no
avail, the idea that looks most promising is to split it into two
tables and set them both to have scroll bars, the problem with this
idea was that both the tables need to be scrolled by the same amount
vertically, i could get the position of one table using the offsetTop
property but could not find a way of setting the offsetTop property
for the other table so they stay aligned. The other issue with this is
that it would be using the onscroll property which does not seem to
show any distinction between horizontal and vertical scrolls..

Here is a sample code :
I want to hide columns with all green cells and I stored the column # that I want to hide into an array, errorColumn(). I am able to hide the rows I want, but I can't seem to figure out the columns.
I think the .has function is the problem because when I use the if(j!=5), it'll hide all columns but the 5th one. I just need it to do that for every column in my array...
Code:
So never done this one before so I am having a bit of a time trying to figure this one out.
Say I have a list of LI element and only a few of them have a inline style of display block, the rest have a display of none.
How would I go about looping through and dertmining the number of elements that have a display of block?
for(var m = 0; m < li.style.display.length; i++)
{
alert(m);
};
The above is just crazy but where my mind melts..

View 9 Replies View RelatedI'm currently working on a javascript form validator and have run into a problem. The validator is used to make sure that the customer has entered a number in the quantity input box of the item they wish to purchase.
Code:
function validateRE(fieldToCheck, strRegExp, msg, min, max) {
if (!min) { min = 0 }
if (!max) { max = 100 }
for (i=0;i<15;i++)
{
if (fieldToCheck[i].value) {
var re_pattern = strRegExp;
if (!re_pattern.test(fieldToCheck[i].value) || fieldToCheck[i].value.length < min || fieldToCheck[i].value.length > max) {
alert(msg);
fieldToCheck[i].focus();
fieldToCheck[i].select();
return false;
}
}
}
return true;
}
Used with:
Code:
<form method="post" action="../some_URL"
onsubmit="return (
validateRE(this.quantity, /^[1-9]{1}$|^[0-9]{2,3}$/,
'Please enter a Quantity.', 1, 3)

View 3 Replies View RelatedI need to be able to create a 2 column table and then based on which column
header is clicked on, sort the list by that column so that each table row is
sorted properly. If possible there might be more than one line in the row
and I would only want to sort on the first line in a given row. Can this be
done using JavaScript. If so, which entities do I need (A table? A form?)
I'm looking for some super light-weight technique to take an existing table and just be able to resize the column headers. I've seen several jquery table plugins out there that seem to do everything imaginable, but I don't really need any of the fancy bells and whistles. I want to use my existing table structure and styles.
