I’m using two javascript methods inside and html page and trying to run that page in IE7 but its is giving JavaScript syntax error. Can you help whts wrong here..?

function validateRow()
{
var desc=document.getElementById(“desc”);
var trimDesc=Trim(desc.value);
if((trimDesc==null) || (trimDesc==”))
{
alert(‘The RoutePlan must have a description’);
flag=false;
return flag;
}
return true;
}

function Trim(str)
{ while(str.charAt(0) == (” “) )
{ str = str.substring(1);
}
while(str.charAt(str.length-1) == ” ” )
{ str = str.substring(0,str.length-1);
}
return str;
}

In the above code:

var s = navigator.userAgent.toLowerCase();

@Robin: correct. Our final beast:

var isIE7 = /*@cc_on!@*/false && ( parseInt( s.match( /msie (\d+)/ )[1] ) >= 7 );

The trouble with the JScript detection ideas is that the JScript version is independent of browser version.

var isIE7 = /*@cc_on@if(@_jscript_version>=5.7)!@end@*/false;

var Browser=new( var w=window; var d=w.document; var ua=navigator.userAgent.toLowerCase(); this.ie = w.VBArray; this.ie5=(this.ie && (!d.createEventObject || !d.namespaces)); this.ie55=(this.ie && !d.implementation); this.ie6=(this.ie && d.implementation); this.ie7 = (this.ie && w.XMLHttpRequest); this.opera = w.opera; this.gecko = (w.netscape && !this. opera); this.khtml=(ua.indexOf("safari")+1 || ua.indexOf("konqueror")+1); )()

This always works for me:
version=0;
if(navigator.appName.indexOf(“Internet Explorer”) != -1)
{
temp=navigator.appVersion.split(“MSIE”);
version=parseFloat(temp[1]);
}
if (version == 0) //NON IE browser will return 0
{code}
if (version == 6)
{code}
etc.

Not sure that last one is the way to go. My IE7 beta @_jscript_build is 5700 and my IE 6 is 8820. Really shouldn’t be branching code based on version anyways. Object detection (when you need to use the actual object, not as proposed in the examples here) is really the only way to be safe.

Try this one:
var isIE7 = false;
/*@cc_on
@if (@_jscript_build >= 8832)
isIE7 = true;
@end
@*/

If you are using a Javascript library, thereâ€™s a chance that the XMLHttpRequest object has been automatically added. I doubt Abeâ€™s method would be added by a library so use that instead.

Btw, I settled with the obvious
var result = navigator.appVersion.indexOf(‘MSIE’) > -1;
(should be fine as long as no other browsers set their navigator.appVersion to contain ‘MSIE’ (why would they do that))

the conditional compiling stopped working on me, it worked fine on my intranet server, but when I put it on the internet it stopped detecting properly (security zone setting?)

//If script is executed width , then document.body is not available yet.

if (window.XMLHttpRequest) {
if(document.all){
document.write(“IE 7″);
//IE7
}else{
document.write(“Mozilla”);
//mozilla, safari, opera 9â€¦etc
}
} else {
document.write(“IE 6″);
// IE6, older browsers
}

This works perfectly as welll…

I have tried:

isIE7 = true;

it did not work – everytime isIE7 was true even in IE6 :(

I tried:
isIE7 = false;
/* @cc_on
@if (@_jscript_version >= 5.7)
isIE7 = true;
@end
@*/

no good – does not work in IE7 :(.
The final solution is??!!!??

@DannyB:

I think the proper code is this:
isIE7 = false; /* @cc_on @if (@_jscript_version >= 5.7) isIE7 = true; @end @*/

I’ve been looking all over for something like this. A site I just launched: http://www.syndicate-cycle.com was written for IE7. Many of the customers that view the site are IE users. The page works but looks bad in IE6. I want IE6 and below users to see a warning page and then allow them to either upgrade or continue to the site. This code will probably work for me except it’s only a snippet and I don’t know how to program it fully to make it work. Can someone finish the code so I can implement it? THANKS!

You could use conditional compilation… untested but should work…

isIE7 = false;
/*@cc_on
   @if (@_jscript_version == 7)
          isIE7 = true;
   @end
@*/
