Error: ‘VEMap’ is undefined


If we get the above error while working with Virtual Earth first thing we need to check is whether the internet connection is working or not.

Next thing to check is whether JavaScript is disabled for the browser. And if this is the case, to enable it in case of IE.

Go to Tools à Internet Options à Security Tab

Find the entry Active Scripting and enable it.

Hope it helps.

Get QueryString values in JavaScript


Hi,

We can make use of the following functions to get the value of querystring parameters through JavaScript

// helper function to get the query string
function Querystring() {
var querystring = location.search.substring(1, location.search.length);
var args = querystring.split(‘&’);
for (var i = 0; i < args.length; i++) {
var pair = args[i].split(‘=’);

 temp = unescape(pair[0]).split(‘+’);

 name = temp.join(‘ ‘);
temp = unescape(pair[1]).split(‘+’);
value = temp.join(‘ ‘);
this[name] = value;
}
this.get = Querystring_get;

}

function Querystring_get(strKey, strDefault) {
var value = this[strKey];
if (value == null) {
value = strDefault;
}
return value;
} 

Suppose our current page url is

http://mycustompage/home.aspx?id=1020

To get the value for id we’ll do this

var qs = new Querystring();

var idValue=qs.get(“id”, “”);

 Bye..
