The server side language I use tomahawk, you won't know that cos it's developed by my boss and is only used internally within the company. It's based on Perl
-
it works now, my colleague just add try{} catch(e){} around my code, then it works!!!
-
I think it's cool and useful, it helps a lot for browser script to communicate with server. but it's tedious too
-
I use AJAX , which has javascript, xml, and server content

hi there, I'm developing an AJAX web chat system. I got all the data to the server page, also i'm able to insert data into database. however, i can't display data back to the display screen. Please help~~~~

You can pass html content to an XML file by using POST method. Then you need a seperate server page where xml content is displayed. for example: xmlDoc.open("POST","your server page","true");xmlDoc.setRequestHeader("content-type","application/x-www-form-urlencoded");xmlDoc.onreadystatechange=handlesent;var param="media=1";xmlDoc.sent(param); Hope this helpsJane

I think you can change position by using css.

Sorry, another question, how do you add the scroll bars in the page so that the code is displayed in the frame?

Hi there, could anybody there tell me what are the possible reasons for the error : Object expected, I have created objects to use. part of my code is like this:<form name="calculator" action="" method="post" ><table><tr><td><input type = "text" name = "screen" id = "screen" size = "18"/> </td></tr></table><table><tr><td><input type = "button" name = "one" id = "one" value = "1" class = "btn" onClick = "add2screen(this.value)"/></td></tr></table>it's a javascript calculator, whenever I click on a button, the error message pop up!
-
Hi everyone! I'm developing a calculator using javascript. I have problem on storing the input field value for later on to refer to. That is when everytime user click on a button, that button's value would be stored in an array, when two values are collected, then perform the calculation depend on the operator been clicked.Could anybody give me idea on this?
