Do meta tags still work? I have read some articles that say it is out dated.. Or is there a better way to have a web page show up in the top 10 on a search engine?

or could you offer some sugestions?

Also should meta tags be used in only for the index.html or all html docs for a site?

thanks, in advance!

AFAIK, meta tags are still using in webpage. eg: Wordpress blogging software has meta tags in each and every pages.

but the important thing is that meta tag is not going to help your blog or site to get high rank in search engines. if you want to get high rank in search engine, you have to learn about how to drive the traffic to your blog/site, how to promote your blog/site and so on.. there are a lot of resources about this on internet.. you just need to google it.

Jumping to dynamically created named anchors in IE (JavaScript)

This is driving me nuts. I have some JavaScript that creates a bunch of named anchors on-the-fly using code like this:

var a = document.createElement("a");
a.name = "my_anchor";
document.body.appendChild(a);

Later on I have some code that will jump to the anchor, e.g.:

window.location = "#my_anchor";

Works fine in Firefox, Opera and Safari. In IE7 nothing happens - it acts as if the named anchor doesn't exist. Anyone ever come across this before?

I managed to reproduce this and have no idea why it doesn't work, theres obviously something fishy going on (well, it is IE after all). To get it to work I had to set the ID of the anchor instead.

a.id = "my_anchor";

Hi
i am unable to compare in javascript.when i am compare boolean result
it
dosenot display output.following is the code.

function stateChangeHandler()
{
if (xmlHttp.readyState == 4 || xmlHttp.readyState == 'complete')
{
var result = new Boolean();
result = xmlHttp.responseText;

if ( result==false )
{
alert("not available");
var label=document.getElementById('lblMessage');
label.innerHTML='NotAvilable';
}
else if( result==true )
{
alert("available");
document.getElementById('nameList').innerHTML ='Available';
}
}
}

in my above code in result i am getting response true/false.
i am getting response from my vb.net code.is it case sensetive
because in vb.net it got True and in javascript we comp with true
when i am run the code it dose not compare the result (true/false) value
with given condition.Can anyone tell me where i am going wrong?

Thanks.

I did not understand your question very well, but as i know:
The vb.net is NOT case sensitive. So 'True' is the same as 'true' in vb.net.

Can you post the called vb.net function code ?

rahul.net114-Jul-07 1:23

4-Jul-07 1:23

Hi Luay.Essa
i know vb.net is not case sensitive.in my application i am
checking username is available in database or not using AJAX.if user name
is available then i am sending false through Response.Write.When i catch
the response in javascript like
var result = new String(xmlHttp.responseText);
then i compare if response is False then giving message in label that
not available if response is True then i am giving message Available.
when i try to compare
if (result=='False')
{//message here
}
but it is not comparing.if condition become true means result contain False in that case also it goes to else loop.
i cant understand why?Cany u tell me why it is happening?

Thanks.

Re: unable to compare in javascript [modified]

My first advice to you is to write the following line:
alert( result );
just to be sure what is the content of 'result': is it 'True' as keyword or 'True' as string.

My second advice and for everyone who faces a bug in javascript: is to use firefox with FireBug extension which displays the javascript error and allows you to debug the javascript code.

rahul.net114-Jul-07 2:47

Hi Luay.Essa,
I already write it.In alert it displays True.How did i know it is
a keyword or string. i am sending it as follow in my vb.net function.
dim isAvailable as boolean
then when i got response that user name is available or not if already in database then
isAvailable=0
response.Write(isAvailable)

then i caught response in result and watch it in alert(result);
when i saw response then it shows (True/False) depending on output
and it also shows HTML code on page in alertbox.

I cant understand your second advice.i am using firefox browser.

Thanks.

My code is as follow...

I am sending my code with it.

My javascript as follow.

function OnChangedUsername()<br />
{<br />
if(document.Form1.newuserid.value == "")<br />
{<br />
//document.Form1.btnCheckAvailability.disabled = true;<br />
}<br />

{<br />
//document.Form1.btnCheckAvailability.disabled = false;<br />
}<br />
}<br />
<br />

{<br />

Try this:
var msg= new Boolean(oRequest.responseText);
// or var msg= oRequest.responseText;
if (! msg)
{
alert("not");
label.innerHTML = 'NotAvailable';
label.style.color='Red';
}
else
{
alert("available");
label.innerHTML = 'Available';
label.style.color='Green';
}

As for my second advice, see this page: https://addons.mozilla.org/en-US/firefox/addon/1843

Download the extension and use it in FX. Its very helpful to find bugs in the
javascript errors
