I want to switch entire rows/columns around in a table. Move rows up/down and move columns left/right. This works fine in IE/opera but has a few problems in firefox.
First of all, is this the 'right' way to do this or is there a better way? Firefox doesn't support swapNode().
When moving rows up/down (top one in demo) firefox takes a few clicks to work when it should be one click on the button. I have no idea why. Code:
I have a javascript function that catches a click event of a row in a table, but I am looking for a way to simulate a click in the first row on page load.
function onRowClick(row) { //Do something }
My table is actually a .Net Datagrid named dgrList, here is the grid
Now when I try to run something like onRowClick(document.frmRemoteScan.dgrList.rows(0)) ;
I get the message that dgrList is null or not an object, and when I loop throught the elements in my form, dgrList is not one of them (yes it is between the form tags).
My question, is there a way to reference the created table via javascipt? Or does anyone have a way to simulate the row clcik via javascript.
I'm trying to implement is a table with editable rows and columns that will feed back into a database. If I could do it with AJAX that would be great too, but I'm not too familiar with javascript. I don't need the code, I need more of an idea. The HTML Table is currently a recreation of the MySQL table minus a few columns. Its all in text, but if I could make the text editable, or better yet, make the text turn into input boxes it would be really cool. I'm not really sure what kind of methods and properties I would need, or quite how to put it all together. What do you think is the best way to go about the entire project?
I have a dynamic HTML table which gets populated by coldfusion and displayed in the page, I have a column called performace which holds numeric values. I need to select the top 3 best performace value in the column and then highlight the entire row in different colours (top 3 values for performance). Can any one help me in doing it?My server can run only Javascript and coldfusion, No Ajax/PHP.I need a complete set of code which such that I will add the script and it performs the calculating and highlighting part.
Here is the example i am trying to achieve, following is the dynamic HTML table(with form) created using PHP and you will find checkboxes being named as 'select[]' and textarea as 'comment[]' the numbers within the boxes are random numbers.. i need to validate these two fields from the HTML table using Javascript before this form is submitted..i have this array defined in PHP and able to access the same array in my javascript..but for somereason i am unable to get the values associated with the table elements:
How can I use jquery to cycle through all the table rows I have in a table, and hide the rows that contain a specific HTML value that I pass to jquery?For instance, I have a table full of students, and courses each student is taking. If I want to hide all the rows where the course is Chemistry (regardless of student), how would I do that?I already have captured the HTML value, what I mainly need help with is how to tell jquery to hide ALL of the rows with that HTML value, rather than just the row I click on.
I have a link to append a new table with the same fields. What I would like to do is when I click on "Append new table" link, I would like to convert all the existing fields in the table in a single row instead of displaying them by columns. Can somebody give me some inputs on how I could go about implementing it
i have the a drop down list that depending on the user selection display the list of results for example if (select color) display (red, blue, pink)if select car display(ford,bentley,ferrari) and so on but now i am trying to put the result in a table each element to their own or column.
I'm trying to validade a table that has 20 checkboxes (5 columns and 4 rows) and that needs to have at least 2 checkboxes checked in each row and column.I've managed to create the validation for the row part (all checkboxes in the same row have the same name).I've also created a custom class rule (all checkboxes in the same column have the same class) but it doesn't seem to work. It only shows the row validation messages (labels that are display next to the last cell in each row) and not the column rule message.
calculating the summed values of a column. Also, the row values are subtracted from each other eg:
col1 col2 col3 row1 a b = a-b row2 c d = c-d row3 =a+c =b+d =a-b+(c-d)
however there can be N number of rows. I have listed below and example I have done to calculate the subtracted values but I am having difficulty doing the summations.
i'm creating a ASP page, which is going to have a form in it that needs filling out. part of the form will be a table with a header row, then the next rows will have text boxes that need filling out. is there a way of putting in a dropdown box that contatins numbers that will dynamically show the rows. for example if i select 5, then five rows of text boxes will appear. if i select 14 then 14 appear.
I have some JQuery that makes an Ajax call and then adds some rows to an existing table.
function LoadDestinationTable() { $("#destinationTable tr:gt(0)"[code]...
The problem is that the only place where the click event fires is on the rows that were added when the page was 1st rendered – the th, for example.I also tried adding an onclick event handler to the input button’s creation – that also does not fire.
I 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..
I have a material table wich contains the article number, a quantity input field, a max quantity field... How can i test that the input quantity is less than the max quant one ? 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...
I have a need to select all table rows in the outer table of a cascading table structure, that is a table with contained tables. I tried to use the "Context" section of jQuery, but the table rows of the sub tables are being selected as well.
I 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.
The code sortes/reverses the rows of a table with data upon the correspondent chosen column.

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?
