Member Extensions

Remarks

Boolean extensions are part of the Microsoft Ajax Library. They add functionality to the JavaScript Boolean object and provide members that are more familiar to .NET programmers.

For more information about the JavaScript object that this type extends and about its constructor, see Boolean Object in the Language Reference.

Example

The following example shows how to create a new Boolean object and invoke the Microsoft Ajax Library parse function to create a Boolean value from a string.

var a = new Boolean(true);      
if (a == true){
    alert("a = true"); 
}else{
    alert("a = false");
}

var b = Boolean.parse("true");
if (b == true){
    alert("b = true"); 
}else{
    alert("b = false");
}
