API Object

cloneObject(x)

cloneObject : Object -> Object

Types

x : Object
return : Object

Description

Returns a copy of x.

extend(x, y)

extend : Object -> Object -> Object

Types

x : Object
y : Object
return : Object

Description

Returns an object that has all the keys/values of both x and y. If x and y have the same key then it will use y's value.

lookup(propertyName, obj)

lookup : String -> Object -> Maybe a

Types

propertyName : String
obj : Object
return : Maybe

Description

Accesses the specified property of the object. If propertyName is a valid property on obj this returns [Just](API Maybe) the value of the property; otherwise it returns [Nothing](API Maybe).

Example

tlc.lookup("one", {one: 1}); // Just 1
tlc.lookup("two", {one: 1}); // Nothing

prop(propertyName, obj)

prop : String -> Object -> a

Types

propertyName : String
obj : Object
return : Any

Description

Accesses the specified property of the object. This is an unsafe version of tlc.lookup so use it only when the property must exist. tlc.prop(propertyName, obj) is equivalent to obj[propertyName].

Example

If you have an array of DOM elements, xs, and you want to get their offset widths you can do the following.

tlc.map(tlc.prop("offsetWidth"), xs); // [132, 493, ...]

propCall(propertyName, args, obj)

propCall : String -> [a] -> Object -> b

Types

propertyName : String
args : Array
obj : Object
return : Any

Description

Calls the specified property of the object. tlc.propCall(propertyName, [arg1, arg2, ...], obj) is equivalent to obj[propertyName](arg1, arg2, ...).

Example

If you have an array of DOM elements, xs, and you want to get only the ones that have children, you can do the following.

tlc.filter(tlc.propCall("hasChildNodes", []), xs);
