Make A Dynamic (variable # Of Rows) Spreadsheet-like Form?
May 29, 2009
I'm trying to create a spreadsheet style form, where the column headers are set, but the number of editable data rows vary. The idea I have is to create a table and make its table cells editable via contentEditable='true', and use javascript to add more rows when a user clicks a button (id="addRows" -- see below).
Thus far I've put together the html for the static component of the table and I'm putting together the javascript. At this point I have a couple of questions:
1. Is there a better way to accomplish my goal? 2. How can I retrieve the data from the editable cells and group them so when I send the data via ajax, the information can be saved properly - i.e. grouped according to row?
Im trying to make the VALUE element within a form dynamic using JQuery and was wondering if the following is possible and if not what is the way to achive this?
I wonder if i can make the variable data which is [data] in jQuery.post( url, [data], [callback], [type] ) dynamic. for instance, this is the form i want to send,
I am thomas. This is my first post I have a question. I am trying to make a dynamic form. I have seen this addressed in a few other threads, but it is first of all not exactly like my problem and also, the language of the explanations is not simple enough for me to understand.
I am trying to make a form that has 1 box that asks how many designs a customer wishes to order, then based upon that number, reveals that many pairs of text boxes below; one should be with the label, �name of design, while the other should be with the label quantity of design. That way, if a user enters 4, four pairs of these boxes will appear, asking him specific names and quantities
If I set up a variable quantity to the value of the text box, I think I should be able to loop like,
for x=1; x<=qty.value; x++ but then I am confused about how to make the thing render the text boxes. My primitive knowledge tells me I could do something like document.write. But on another thread I read I saw that I could also use
I have just took from internet dinamic table. this table is dynamic and its rows dynamically can be increased. it sum but not like integer for ex. in row1 i enter 20 and in row2 i enter 5 it sums like 205 but i need it sums like 25
I wasn't sure if this should go in the JavaScript or PHP forum, so I decided JavaScript.
I have created a site that has a form where the user can create as many rows as wanted. I really have no idea how I can then get this information to use in PHP.
Here is my JavaScript function creating the rows code...
I read something about naming each element something such as 'el[]' and then iterating through it on the PHP side, but that didn't make much sense to me. I have only been using PHP for a few weeks now so I'm pretty new.
MY PROBLEM IS I AM ENTERING DATA IN 3 ROWS after that CLICKING NEXT BUTTON AND GOING TO 2ND PAGE THEN IN THE 2ND PAGE I AM CLICKING PREVIOUS BUTTON TO SEE THE FIRST PAGE DATA ;I AM ABLE TO SEE THE 1ST PAGE DATA BUT I WANT TO DISPLAY DATA IN MY JSP PAGE I AM WRITING CONDITION LIKE THIS
If(formData != null) IAM CALLING addRow('myTable') FUNCTION
I AM GETTING EXCEPTION PAGE NOT FOUND
why i am calling like this because
as u can see the addRow(id) function
for every dynamic row i am putting the remove button at the left side(user can have choice of deleting the row)
i want to call this Javascript function addRow() for satisfying IN both Add and Modify operations and also it will satisfy in Next and Previous modes; Code:
I am working on some JavaScript that dynamically adds rows to a table in response to a button click. A new row does appear on the screen when the button is clicked. However, that table to which a row has been added is itself contained within an outer table (to handle the desired screen layout). That outer table does not properly grow to contain the new size of the table to which the row was added. (More specifically, I have sporadically seen the outer table grow correctly, but then most of the time it does not grow as desired.) Is there something that needs to be done in the code that will make the right thing happen? (This phenomena appears in Netscape 7.1 -- things work correctly under Internet Explorer 6.0)
A second anomoly concerns a button that appears in the newly added row. An "onClick" event is associated with that dynamically added button. The newly added button works correctly under Netscape 7.1 but fails to work under Internet Explorer 6.0. (It is like Explorer will not honor an event that is set in place by code that is dynamically created after the page is loaded.) Shown below is an excerpt of the code that is attempting to set up the desired button. Is there something apecial that must be done in the code to get Explorer to handle this properly (I have tried spelling things as both "onclick" and also "onClick")?
tbldata = document.createElement("TD"); item = document.createElement("BUTTON"); v = 'doaction("Edit",' + n +')' item.setAttribute("name","Edit"); item.setAttribute("onclick",v); textitem = document.createTextNode("Edit"); item.appendChild(textitem); tbldata.appendChild(item);
I have a temp HTML file that is based the code I found on this site at [URL]. It dynamically adds and removes rows from an HTML table with inputs in the cells. I have tweaked my copy a bit to match our needs. Of importance to this post is that column 1 is simply the row number. Unfortunately, I am unable to figure out how to re-sequence the first column if a row is deleted. For example, if there are 4 rows, and I delete row 3, I need to re-sequence (re-number) the values to reflect 1, 2, 3, not 1, 2, 4.

Below is the insert logic (which adds a delete button for the row).
I have written code for adding and removing dynamic rows.i am using same file for both ADD and MODIFY operations.this page is working for ADD operation.lets say for MODIFY operation one employee has added 3 rows and i need to display those rowsand user can edit thoese rows and finally these values will be submitted to database.problem is coming in modifyRow() method.how to accomodate array values in the dynamic rows in modifyRow() method.Please review the code in that method?while loading the values the structure should be same as addRow() method?
this is dynamic rows code.when i click remove(-) any row i need to get respective checkbox id; for example when i delete row3 i need to get checkbox id as houseCheck3;when i delete row2 i need to get checkbox id as houseCheck2; once i get the id of that checkbox its easy for me to get the value;
I have a set of data that I display in a table. Each row has a category and there may be a dozen or more rows in the same category. I'm looking to add filter buttons to the page to hide/show categories on the fly.
Currently I can: Set the id on the tr to (category name) or to (category name.data id).
Using the first, is there a way to hide all rows with that same id? It seems currently to only hide the first row with that id.
If not, is there an easy way to find all rows whose id starts with (category name)? I figure I could regex over every element in the page looking for ones that begin with a particular id, but that would be silly.
Also, is there a way to refer to every row of a table? I'd like to first hide every row, then show those in the required category.
this is dynamic rows code.when i click remove(-) any row i need to get respective checkbox id;or example when i delete row3 i need to get checkbox id as houseCheck3;when i delete row2 i need to get checkbox id as houseCheck2;once i get the id of that checkbox its easy for me to get the value;
I'm trying to create dynamic rows in the existing table.
<html> <head> <script language="JavaScript">
[code]....
In the above code, i am able to create dynamic row only after the last row of the existing table. i.e( I am able to add rows after row2_column1 ,row2_column2).Hence on click of the "create new UPI" button only one row will be created.
Is it possible to create a new row after each existing row? (i.e. a new row after row1_column1,row1_column1 and a new row after row2_column1 ,row2_column2). What i exactly i need is to find the total number of the existing rows and on click of the button a new row should be created after each existing row.
The issue I am having is how to modify the following html/javascript to show only rows that do not have a certain value. For example I have 2 rows with the following values:
Row1Column1 Row1Column2 Row1Column3 Row2Column1 Row2Column2 Row2Column3 But I do not want display any row when a value in Column3 equals
Row2Column3. Therefore in this example I will display Row1 but not Row2. The following code displays a table of rows and is running in a servlet container using tomcat, hence the predefined tags of ${.....}. I know this forum is not for server-side programming but this issue really a html and javascript issue. The issue I would liked answered is how to modify the html/javascript so when a ${wfinfo_task_role} value of "cdm" is be displayed then the row will not be displayed in the table.
I use the below code to add or remove a row from a table using javascript. The code works fine on IE however it doesnt work on Firefox, can anybody suggest reasons why this might be doing so?
The id "table1" is the ID of the table I am trying to insert the innerhtml into.
function addRoom() { var row = document.all("table1").insertRow(); var column = row.insertCell(); column.innerHTML = "input type='text' name=txt1>";
getting dynamic rows inputs to multiply 'onchange' of the value in the input in each row. It works in the first row inserted no matter what rowindex that row is moved to. All following rows only accept the initial input value and never change the 'cost' innerHTML of the colRow[i]. I figure I need a parentNode.parentNode syntax to make this function work in all rows.
Every thing is Client-side javascript and all rows are inserted to 'cartbody.insertRow[0]'. 'qtymultiply()' Function As is:
Code:
function qtymultiply(){ var cartitems=document.getElementsByClassName('itemrow'); var colRows=cartitems;
This is an example of what I currently have. There is also a button which adds more rows. It wasn't too hard to get it working using CSS and innerHTML:
However, due to mass css headaches with the layout, I' like to see if it can be done it tables instead and using the DOM methods (nodes, createElement etc)
so far, the examples I've seen either don't allow the same functionality or don't work across IE5+(win), and modern versions of FFox, Safari and Netscape (MAC + WIN)
Does anyone know of a good class/example/tutorial?
I am having a problem with the last results. I can't seem to be able to get the input2A and input3A to appear. I don't seem to have a problem with the show and hide after a number is entered and submitted. If anyone can answer my problem I will be greatly appreciated with a prize. I actually have submitted it more than once and I haven't had anyone been able to answer it yet. Code:
I've taken a look around the net, and I've noticed some spreadsheet scripts out there written in javascript/html, and I've noticed they mostly seem to lack some functionality/formulas.
So I've been playing around with creating my own spreadsheet, and so far I have something approximating a spreadsheet in Firefox.
I have a couple of issues with making cross-browser, as I clearly do not understand the problems with the Opera and IE browsers.
Current issues:
1. IE apparently only recognizes every 2nd column/row when entering data, but will quite happily allow the user to scroll around the page with the mouse-wheel and the arrow keys.
2. Every time the user switches cells, what is happening in the background is that the innerHTML of the cell is being recorded, then copied into a textfield for editting, which is then swapped for the old innerHTML. However in IE (and occasionally in Opera) what happens sometimes is that I get a double event firing or something weird like that, and I end up with an text field with its OWN innerHTML inside itself (gotta like that self-referencing stuff).
3. Who knows what else is wrong with the formulas in IE since I can't get past issue #1.
4. Opera apparently doesn't recognize the mouse-wheel event at all, and only fires the onkeydown event once (even if you hold down the key on your keyboard). Also, Opera also occasionally likes to swap the innerHTML for itself as with issue #2 above.
