Hi Mihir, You can get the values of textboxes generated dynamically by calling request. Hey Viral, Thanks for replying.

Once you provide the name to newly created element, it can be accessed from JSP by calling getParameterValues.

And you have to iterate through request to get all the values and then you can insert these values to the database.

Then there's the tbody table body containing a bunch of tr table rows.

Each table row contains a certain number of td elements table cells. With these requirements in place we can start coding our JavaScript file. Our starting point can be the following HTML:.

Say we want to create a table head, we can do document.Here the counter is starting from 1 to 5 depending on the respective alphabets In real world dynamic Values.

For each table row, new cell is inserted to the last position in the row. Sorry, never mind! Is it possible to add the whole table itself depending on user input? Example there is a table for house but people may have more than one house and if they have, once you click ADD, boom another table to write the details?

CreateTextFile fileLoc, true ; file.This article is an overview of some powerful, fundamental DOM level 1 methods and how to use them from JavaScript.

You will learn how to create, access and control, and remove HTML elements dynamically. Remember this technique. First, you create elements from the top down; then you attach the children to the parents from the bottom up.

You can build this table and its internal child elements by using just a few DOM methods. Remember to keep in mind the tree model for the structures you are planning to create; this will make it easier to write the necessary code.

The first element of the list is located at position [0] in the array. In this example, we set the myP variable to the DOM object for the second p element inside the body:. For example, if you want to set the style background color property, you just add:.

How to iterate through html table rows and columns with Javascript (with source code)

Use the document object to invoke the createTextNode method and create your text node. You just need to pass the text content. The return value is an object that represents the text node. To insert this text into your HTML page, you need to make this text node a child of some other node element. So, by calling myP. After testing this sample, note that the words hello and world are together: helloworld. So visually, when you see the HTML page it seems like the two text nodes hello and world are a single node, but remember that in the document model, there are two nodes.

The following figure shows the recently created Text Node object inside the document tree. Another important note is that the appendChild method will append the child after the last child, just like the word world has been added after the word hello.

So if you want to append a Text Node between hello and world, you will need to use insertBefore instead of appendChild. To create a node simply call document. For example:. Nodes can be removed. Text node myTextNode containing the word "world" still exists. For the rest of this article we will continue working with sample1. The following figure shows the table object tree structure for the table created in the sample.

At the end of the start function, there is a new line of code. The table's border property was set using another DOM method, setAttribute. You can set any attribute of any element using the setAttribute method. This example introduces two new DOM attributes. First it uses the childNodes attribute to get the list of child nodes of mycel. The childNodes list includes all child nodes, regardless of what their name or type is.

Like getElementsByTagNameit returns a list of nodes. The differences are that a getElementsByTagName only returns elements of the specified tag name; and b getElementsByTagName returns descendants at any level, not just immediate children.
