- All the inputs with name attribute (checked checkboxes and fields) will be passed to the $_POST array in PHP, so you basically have them in one array – Ivan Yonkov Commented Aug 6, 2013 at 6:05
- You should make yourself acquainted with jQuery. It is in mho a brilliant JS library which makes many things in JS generally a lot easier if not at all possible. I know, it is always extra work to learn another 'language' but it is definitely worth it. Using jQuery you will find several elegant ways to do your project. – Carsten Massmann Commented Aug 6, 2013 at 6:11
- I changed the code as you said.and it gives only the values of two rows. And is there a way to identify whether its a textbox or not. – harshanii Commented Aug 6, 2013 at 6:33

Reset to default 3Your code is right, just little change over there
<TR>
<TD><INPUT type="checkbox" name="chk"/></TD>
<TD> 1 </TD>
<TD> <INPUT type="text" name="<?php echo $i; ?>"/> </TD>
</TR>
replace with this code
<TR>
<TD><INPUT type="checkbox" name="chkbox[]"/></TD>
<TD> 1 </TD>
<TD> <INPUT type="text" name="txtbox[]"/> </TD>
</TR>
and your work finish
var rows=getElementsByTagName("tr");
var noOfRows=rows.length;
for(int i=0;i<noOfRows;i++){
var html=rows[i].innerhtml; /*a single row's inner html say (<td>apple</td><td>25</td>)*/
var td=html.match(/(?!<td>)([\s*\w*]*)[^<\/td>]/g);
/**
td[0] is 'apple', td[1] is '25'
**/
}
