Quick help please!

If you want some javascript to only occur if you're using IE (like 4+), how do you specify it?

I'd like to make it more than just IE4 but I don't know every single browser which supports the javascript command. It's field disabling and worked on IE but not NS.

what code have you got that you need to do this.

well by referencing an object you can do this

if      (document.all)           {}
else if (document.getelementByID){}
else    (document.layer)         {} 

other than that the best way to reference an object is this

<script type="text/javascript">

  function blah(what, col)
  {
    what.style.backgroundColor=col;
  }

</script>

<div onmouseover="blah(this, black)">blah</div> 

as you can see there is no need to give the attribute an id, just pass 'this' in the function call and you can use that reference handle.

lol what are you talking about?

I need the javascript only to occur if the user is using IE4+

It's a client-side form field disabling/enabling which doesn't work in NS and causes a problem.

[Andrew-J2000]

well use this then

if      (document.all)
{

}
else if (document.getelementByID)
{

}
else    (document.layer)
{

} 

or try this

if (navigator.appName == "Microsoft Internet Explorer")
{
  //execute this chunk of code
} 

or

if (parseInt(navigator.appVersion) > 3)
{
  
} // end of Nav4+ only if 

[geiger]

Thanks.

i can't remember what the codes supposed to be like for mozilla or opera

but just do this

alert(navigator.appName); 

and replace the app name accordingly

if (navigator.appName == "Microsoft Internet Explorer")
{
  //execute this chunk of code
} 

however what i said t you in the first place about using 'this' will be better than make cross browser scripts as it works on any browser that has js enabled.

Thanks.

This field disabling script works in IE and Mozilla/NS6:

Odd... I'll talk to my scripter. Mine isn't! It gets stuck whichever way it starts out in NS/Mozilla.

If I want to have multiple enabled and disabled fields, how do I edit it? Also if I want to enable and disable checkboxes, etc. can I put "this"?

function makeDisable()
{
var x=document.this.name <-- does this work?
x[0].disabled=true
}

function makeEnable()
{
var x=document.this.name <-- does this work?
x[0].disabled=false
}

Do those work, and how do I add more than one?

[geiger]

Anyone?

[Andrew-J2000]

as i said before use 'this' as a reference handle so it will work in any browser

function makeDisable(what) 
{ 
  var x = what.name;
  x[0].disabled = true;
} 

function makeEnable(what) 
{ 
  var x = what.name;
  x[0].disabled = false;
} 

now call it by this

makeEnable(this) or makeDisable(this)

Sorry I know absolutely Zero javascript so you have to talk me through this

So if I want a checkbox switched it would be
var x = select.viewable1;
var x = select.viewable2;
var x = select.viewable3;

and field
var x = field.description1;

?

erm, i'm not sure what you mean. Do you have the page online somewhere or can you post it form included

[geiger]

Yeah but its in a pass protected area. Do you have a real-time chat client?

[Andrew-J2000]
