how to pick up value

[fareedreg]

I am using php with ajax with library project.. I am displaying (bookname,price,issue charge etc) from mysql database into divtag through AJAX.. but when i would like to insert fields in mysql database ... i would not be able to pick issue charge from div tag..

 

 

my first file is bookissueadd.php in which i m using ajax and and displaying value in txtbook divtag from ajax....code is followin

 

<div name="txtHint" id="txtHint"><b></b></div>    </td> 

 

 

 

second file is selectbookname.js ..... code is following

 

 

function stateChangedbook()

{

if (xmlhttp.readyState==4)

{

    document.getElementById("txtbook").innerHTML=xmlhttp.responseText;

}

}

 

 

 

third  file is getbookname.php which i m calling  from javascrip...

 

$cal = $bookprice/100*$perval; 

 

 

this $cal variable is getting issue charges..... now how can i get this  value backto my bookissueadd.php so i can process its value at submit time
