howto JavaScript take HTML input variable -- continuous

Please copy & paste the following code (it is SOME text input)

My trouble was cannot take document.table1.aX.value where X is something~

Code:

<script language="javascript">



function sum(X)

{

alert( "sum =  " + (parseInt(document.table1.aX.value)+parseInt(document.table1.bX.value))  ) ;

return true

}



</script>





<form name="table1">

<input name="a1" type="text" /><input name="b1" disabled="disabled" value="1" type="text" /><input onclick="sum(1);" value="a1+b1" type="button" /><br />

<input name="a2" type="text" /><input name="b2" disabled="disabled" value="2" type="text" /><input onclick="sum(2);" value="a2+b2" type="button" /><br />

<input name="a3" type="text" /><input name="b3" disabled="disabled" value="3" type="text" /><input onclick="sum(3);" value="a3+b3" type="button" />

</form>

I try to explain the design, each row doing the same thing: SUM of text input.

I would like to have a JavaScript function / module
for MANY rowS.

So the JavaScript function has 1 input parameter to tell which row.

Hello,
JavaScript does not allow call by reference parameters so you can't do
document.table1.aX
and expect X to represent the value. Instead it represents an element named "aX"

:D

Accept my proposal ;)

JavaScript can do much job at client side, IF I got a text file AT CLIENT side machine, I mean the file is NOT at web server but at user machine, I would like to open the file by browser WITHOUT network

another JS question, can anyone show me reference link on howto:
open .txt text file in JavaScript please?

You shouldn't reuse old topics though.

Assume that having NO networking, NO internet...
Can I using a browser to open/read a file? like .txt file type or any other file type?

Well, I know I can open file(s) by click
File -> open -> browse the file(s) in directory inside harddisk

Answer: following link:

please help if anyone know... JavaScript onclick()

onclick() working on <a href=link></a> tag?

reference: http://www.w3schools.com/jsref/event_onclick.asp

Sure, it works:

Code:

<html>

    <body>

        <a href="http://google.com" onclick='alert("Hi there"); return false;'>Some link</a>

    </body>

</html>

thank you for replying, furthermore saying... below the code:

Code:

<script>

function f1()

{

document.getElementById("content").innerHTML = 

"<div>JavaScript howTo?</div>" +

"<div>onclick</div>";

}

</script>



<table style="float:center;" border=2>

<tr>

<td style="text-align:center; font-size: 1in; width:3in;  height: 3in"><a href="" onclick="f1();" style="text-decoration:none;">click 1</a></td>

<td style="text-align:center; font-size: 1in; width:3in;  height: 3in"><a href="" onclick="f2();" style="text-decoration:none;">click 2</a></td>

</tr>

</table>



<p id="content">

Please copy and paste the code to .html file, I would like to
onclick text or a href link THEN... popup the content by JavaScript function f1()

thank you and see if above clear?

Something like

Code:

for(ii=0;ii<11;ii++)

{

if (ii < 10) j="X0"+ ii ;

else j="X"+ ii ;

document.write("<Option value=\" + j + \"") ......

}

and so on perhaps.

I have to check it out but I think that j will be successively X01, X02, X03 ... X09, X10 and so on
