Extract Data From One Row In A Dynamically Created Table?
Aug 12, 2010
i am creating a table dynamically using java script- the number of cells in a row is constant and the data is accepted from the user from x text boxes(based on number of cells).now, i want to insert a button in the x+1th cell of each row and i want to extract the data in the row that contains the button that gets clicked back into the text boxes for editing.how do i go about doing this? dynamically creating the table is not a problem, but am not able to extract the row data for editing :-(i forgot to mention this- but after editing the data in the text box, i need to be able to insert the data back into the same row from which the data was extracted in the first place...
I would have "thought" it would be a simple thing to get the (unformatted) text in each cell of a dynamic table but I have failed to solve this problem. So...I have a table that the user can dynamically load with data. They click an add button to insert a row in a table which includes a delete button per row if they want to turn around and delete it.The table is inside a form. When they submit the form, I need to read each row and each cell in a row in order to dump it into some format so that the table contents display reasonably well in the email that is sent from the form submission.So the add row function looks like:
function addRow() { //add a row to the rows collection and get a reference to the newly added row var newRow = document.all("mytbl").insertRow();
what I am exactly trying to do is get data from a form, push that data into an array of objects and when a "display" button is clicked, to display the data in the form a div layer with a table in it for each object created. I have problems with dynamically creating the divs. Here's my code
I've created a table with Table Header and the table may or may not contain any rows initially.
I've included a .css file in <head> section of my HTML script and I'm creating rows to the table dynamically using JavaScript (using DOM), and the problem is those created bby DOM are not following style sheet rules applicable for table rows and cells. But the rows created from within HTML script are following style sheet rules. The following is sample which is used to create dynamic row. Code:
I want to create a recipe site with similar functionality to a feature on coolspotters. I've only dabbled in jQuery so I'm not sure how complicated it would be to do this. Basically what I want to do is allow a user to add recipes to dynamically created lists. For example if a user searches for Italian food they should be able to create a list called "Italian" and add italian recipes to the list. Or if they do a search for Japanese dishes they will be able to create a list called "Japanese" and add Japanese recipes to it, etc. I know their would be some back-end code involved but I was wondering if jQuery could handle the front-end. I've only dabbled in jQuery so this sounds like a complex thing to do.
As you can see in the "action" attribute, I'm calling this function:
function SubmitEditedInvoice(invno) { $.post('output.php?mode=6&invno=' + invno, $('#formEditInvoice' + invno).serialize(), function(output){[code]....
The problem I'm having is that no data is passed to the PHP back end. I have verified that the variable invno is correctly passed to the javascript function, and have tested my .serialize() by using a hard-coded form ID, but I still get no data passed through.
I am running through a MySQL database using PHP and extracting all of the makes of cars in that database and trying to create a JavaScript array named after each make. Then I am trying to fill each array will all of the models for that make. When I just try to display each Make and Model in an alert box it seems to come up right. And my arrays seem to be getting created but they won't populate with the models (even though my alert msg shows the loops and everything is working).
PHP Code:
while ($row = mysql_fetch_array($result)) { $i=0; //Used so each model is added to the array starting at 0 and ++ $make = $row['make'];//PHP var used to extract data from MySQL

Haven't used JavaScript since a college class a couple of years ago and haven't used it in the real world for even longer. Never with PHP like this. But I am working on this marketing site and need to be able to list products by type according to each brand and as they can be added to a MySQL database it needs to be dynamic. I have the whole thing working by stepping through separate pages using PHP to populate select fields with the data but I want to be able to dynamically add the content to select field using JavaScript so it can all be done on one page and thought that if I could create these arrays on page load then the right information could be selected client side.
I am Lakshmi.Research scholar.I have a doubt in the usage of cookies in javascript.Normally in order to extract the cookie value we have to specify the corresponding cookie name.But I need automatic extraction.If i give a php file in which the cookies are created using javascript,all the cookies in that file should be extracted.Is it possible?

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 stumbled across jQuery while during a search for my project that involves parsing and extracting content from HTML pages. I have a collection of xpath strings that identifies the data I would like to extract. Wondering if I could use jQuery for this purpose.

So if I add 1 rows, I get 2 text boxes with the ID of 1-medication as I already have a row in place (static) This works fine. However when I try to get the value of 1-medication, I thought I'd get something like value1,value2 but instead I just get value1 If I change the function above to putput a text box with ID of 2-medication, I can get the value of that by itself just fine. why if I have more than 1 item with the same ID, I can't concatenate each value?
There seems to be some strange behaviour when trying to get the scrollHeight and scrollTop of an iframe in IE6.
I have tried several ways of getting these values when the iframe is written into the html. The following return the correct values in IE6, where the iframe's id is 'f':
However this works as correctly in Opera 7. I find this all very confusing. Can anybody shed light onto how I might get the correct values in IE6 when using the createElement() method?
I want to give the user the abillity to add extra fields as needed. I've got it working in IE (surprsingly this works in IE but not in Firefox), however, basically I have an input field for a paragraph. If the user decides they want two paragraps then they can click an image and a new textarea field is show that allows them to add another paragraph. The fields are named as an array for example name="para[0]" the next one would then be name="para[1]". Firefox creates the field and shows it to the user however when you submit the form the new field does not come through. My array of paragraphs consists only of the original number I started with. Any added by the javascript are lost. Again IE this works fine, Firefox it works till you submit the form. Any ideas?
