Ajax to always pull and display data??

[DeanWhitehouse]

I have just started to learn AJAX and i am making a chatroom the problem i am having is on how to pull data from the php file and display the data inside another page, and how to show current data, as it will continuosly be changing. Any one know how to do this, the most i have been able to do so far is display data inside a input field from a php file.

<div id="myDiv"></div>

document.getElementById('myDiv').innerHTML = XMLHttpRequestObject.responseText;

 

innerHTML changes the entire content between the tags cited by the ID of the element.

will this always be updating though??

 

Or will they have to refresh the page?

Use the "innerHTML" property for DIV, SPAN, and similar layout elements.

 

Use the "value" property for INPUT, TEXTAREA, and similar form elements.

 

Use events to specify when AJAX should be requested. The event verbiage "onClick", "onLoad", and "onMouseOver" is very easy to understand.

 

I've created a simple Base64 encoder and attached it to this post. You can see that when a user enters a string and clicks the "encode" button, the encoded string is displayed. I used the "onClick" attribute to make this work.

Ok, thanks for the help and the example code. I have decided to go with an open source chat room. Ajax Chat.
