indexOf returns the position of the string in the other string. If not found, it will return -1:

var s = "foo";
alert(s.indexOf("oo") > -1);

Centering lines of text

Centering a block of text or an image

Centering a block or an image vertically

someArray = [{name:"Kristian", lines:"2,5,10"},
{name:"John", lines:"1,19,26,96"}];
You can use several methods to remove an item from it:

//1
someArray.shift(); // first element removed
//2
someArray = someArray.slice(1); // first element removed
//3
someArray.splice(0,1); // first element removed
//4
someArray.pop(); // last element removed
If you want to remove element at position x, use:

someArray.splice(x,1);

if ( variable.valueOf()=="string" )

"a" == "b"
However, note that string objects will not be equal.

new String("a") == new String("a")
will return false.

Call the valueOf() method to convert it to a primitive for String objects,

new String("a").valueOf() == new String("a").valueOf()
