I read a lot of data from excel sheets into JS arrays.I have a situation where i have name, hours, product id and other few entries.
I have all these details as array in array concept.eg.
array.push(new Array(name,hours,pid,price,place))
Redundant entries that include same names,pid, places will be found in the array.My prob is to sum up all the hours of the records that belong to same name and product id and store the unique records in one array and ofcourse the hours column sumed up.
name pid hours place

I am using a neat postload script to load a bunch of images into the user's cache after the page has fully loaded, and I have a quick question
<script type="text/javascript"> //<![CDATA[ function postLoad(){ if(!window.name.match(/preLoad.complete/gi)){ var images = new Array('img/EnglishOn.gif', 'img/EnterOn.gif', 'img/EntrerOn.gif', 'img/FrenchOn.gif', 'img/butt_1_blank.gif', 'img/butt_1_red.gif');
var loader = new Array(); for(var i=0; i<images.length; i++){ loader[i] = new Image(); loader[i].src = images[i]; } window.name = 'preLoad.complete' } } //]]> </script>
Can this script be modified to check whether an image has already been loaded, and if so, not reload it? I ask because I may have a long list of images and if the user navigates to another page I would like the script to not re-download X number of images Code:
Assume we have one button that fires ajax request, ajax call will talk 15 seconds to load the results. Assume the user clicked on that button first time and waited for 5 seconds, then he/she clicked again. In this case the page will be loaded two times. i.e. first time will be loaded and after finishing the first ajax request, the second one will start!
Is there any way to cancel the second ajax request(both first and second ajax calls come from first button) while having the first one in process? The problem, if the user clicks more than one time on the same button, then a queue of ajax calls will be executed and the user will wait for long to process all of them. So I need to cancel similar requests that come after first request.
I'm building a JavaScript-based calendar for a client that will require me to replace the page's HTML based on the user's input. For example, if the user clicks on a particular date, then the month/week calendar will be replaced with the day calendar. Needless to say, there are several event listeners involved. However, if I suddenly swap out the month calendar for a day calendar, does that mean that there are several event listeners in memory for elements that no longer exist? Or are those listeners destroyed when the elements are destroyed? Basically my question is, every time I swap out the HTML, do I have to detach all of the old events too?
I'm using drupal, and am having trouble to convert a table to a one field two column at code level.Is it possible to manipulate it using jquery using odd and even?
I have created a table to organize data, and upon clicking a row, the user is taken to that data to manage related information to that data. Everything works fine, but something came up where I would like to give them the ability to delete items from that listing. I would like to add an additional column for each row, that will store an image, when clicked on, deletes that item in the database.
My question is: how do you cancel an action based upon a column that is clicked? I'm sure there is, and I don't mind adding a class to the image column for detection... I am unsure how to look further into the DOM event to see what particular td was clicked, if I could, I could then use $(this.attr("class"); to look to check if that specific column was clicked, and to cancel the action accordingly.
I'm having a spot of bother hiding table columns in IE.
With FF, setting the column cell's style.display to none (or changing the cell's class name to style that has display: none) completely removes the cells from the table.
In IE, the cell contents go, but the space they occupied is still there, so the table has an empty column, the same result as setting visibility = invisible.
how to get the total column automatical gets update when user inputs a value in column 1. i believe its some thing to do with javascript onfocus(). i don't know how to do it.
I am attempting to create a form similar to one found in Access where the select box's drop-down list displays multiple columns while the selection only displays the first column. For example, in my app, I have a drop-down for "A", "M", and "D", but when the list drops, it should say:A | AddM | ModifyD | DeleteI don't care about the spacing of the pipe characters, but I simply want the selected item to only show the first column (in this case, the single letter) so I don't have a long select box.
I am trying to implement the "Freeze pane" feature in javascript as it is in excel. I am almost there but am not able to get one last thing. The row header freezing is achieved first column freezing is also achieved. However, the top left column cell (which is supposed to stay frozed during both horizontal and vertical scroll) is not frozen.
I cannot figure out how to total my column data correctly with JavaScript. The code I have will enter a new row, but it is not summing the columns. The new row is just filled with zeros.
function totalColumns() { var tds = document.getElementById('users_table').getElementsByTagName('td'); var sum = 0; for(var i = 0; i < tds.length; i ++) {
i have two columns table and this table is dynamic when clicked add button it automatically adds rows i would like to sum values separetly for ex: when i clicked sum-column1 button let it sums only column1 or when i clicked sum-column2 button let it sums only column2 here is code
<html><head><title>dinamik sheet</title> <script> function addrow(){
i have table with 3 column i want the col3 to be hidden by onload when open the webso is there away to make itbecause in tutorial only shown by onclick
I have a large table with too many columns, I have a column show / hide script. Just to reduce the script size, I want to do some modification. On the First ROW of the Table, there are columns heading, and each have an ID. i.e. <image id="col1"...> Now, I want to have a function where if I pass the ID, it determine the column index it self, OR if I pass the column Index, it will return the column ID.
Ok, if you create multi-column lists with CSS, you tend to get: Code: 1 2 3 4 5 6 rather than:
Code: 1 4 2 5 3 6 One solution for this is here. However, that requires unique names for each list item and formatting the CSS in advance for each list in advance. LAME.
However, that solution can be automated with Javascript and I am almost positive I have seen that done before, I just can't find it now. Can anyone help me out?
How can the user obtain a specific result by choosing values from 2 dropdown list. As a result, the value obtained can not be modified by the user. The table of ten rows by ten columns have to be stored in a mysql dbase.. It's certanly possible , but tedious and time-consuming by using a bunch of "if ... then statements". Considered from a table point of view, the final result is the coordinate of a row value and a column value.
I want to ensure one column in a table is always the same number of pixels wide no matter what the screen resolution is set to on the visitors PC - the other two columns can wrap away top their hearts content.
How do I do this please? The code below doesn't do it.
