Readonly field password protection

[Kal]

Hi guys,

I have a simple text field with a price value which is set to readonly by default. Is it possible to have a button of some kind next to the text field which brings up a password box. By entering the correct password the price can be overridden.

Any help would be great.

<p> PRICE:- <input type = "text" name = "price" id = price" value = "123" size = "5" readonly = "readonly"></p>
<input type ="button" name = "but1" id = "but1" value = "Click To Enable Edit Price Field" onclick = "overRide()">

<script type = "text/javascript">
function overRide() {
var pass = prompt ("Enter the password here","");
if (pass == "abcd") {
document.getElementById("price").readOnly = false;
}
else {alert ("Wrong password!")}
}
</script>

This is completely insecure as the password is visible to any user with "View Source".

Thats great.

Is it possible to hide the password being entered in the prompt box?

No. You need a different approach for that:-

<p> PRICE:- <input type = "text" name = "price" id = price" value = "123" size = "5" readonly = "readonly">
Enter password to enable edit price field <input type = "password" name = "pwd" id = "pwd" size = "10" onblur = "overRide()"></p>

<script type = "text/javascript">
function overRide() {
if (document.getElementById("pwd").value == "abcd") {
document.getElementById("price").readOnly = false;
}
else {
alert ("Wrong password!");
}
}
</script>

You can marginally improve the security by storing the password in an external Javascipt file:-

<SCRIPT type = "text/javascript" src="password.js"></SCRIPT>

This file contains nothing but:-

var correctPwd = "abcd"

and then alter the above script to:-

if (document.getElementById("pwd").value == correctPwd) {

I have made a few modifications, but struggling on something. I have got it so I have default text in the password field, When you click in the field it changes from a text field to a password field which incorporates the function kindly added by Philip M. How can I now have it so that once the user has entered a price and focuses on another field the password field changes back to the text field so that the price cannot be changed
?



<script language="javascript">

function changeBox()
{
document.getElementById('div1').style.display='none';
document.getElementById('div2').style.display='';
document.getElementById('password').focus();
}

function restoreBox()
{
if(document.getElementById('password').value=='')
{
document.getElementById('div1').style.display='';
document.getElementById('div2').style.display='none';
}

if (document.getElementById("password").value == correctPwd)
{
document.getElementById("c_new_line_charge").readOnly = false;
}
else
{
alert ("Wrong password!");
}
}

</script>

<input type="text" name="c_new_line_charge" id="c_new_line_charge" value="19.99" readonly="readonly">

<div id="div1">&nbsp;&nbsp;&nbsp;<input name="pass_temp" type="text" value="Override Password Here!" onfocus="changeBox()"></div>

<div id="div2" style="display:none">&nbsp;&nbsp;&nbsp;<input name="password" id="password" type="password" value="" onBlur="restoreBox()"></div>

function RObox() {
document.getElementById("c_new_line_charge").readOnly = true;
}

</script>

<input type="text" name="c_new_line_charge" id="c_new_line_charge" value="19.99" readonly="readonly" onblur = "RObox()">

Thank you very much for all your help. Works perfectly.

As stated before this is NOT SECURE. I hope this is not a public site.
