.for()

Loop for each value and change it

Iterate over object/array, executing a function for each value.

---

Loop with array/object

_z.for( array, callback, context );

• _z to access UnderZ library.
• for method/action name.
• array array to Iterate over.
• callback the function that will be executed on every value. if this function returned false the loop will break, returning any value will change the element value.
• context (optional) bind new context with callback function.

Returns: array array.

---

Loop with DOM elements

_z(selector).for( callback, context );

• _z to access UnderZ library.
• for method/action name.
• selector select element/s by selector to loop over. ( you can send DOM element or selector)
• callback the function that will be executed on every value. if this function returned false the loop will break, returning any value will change the element value.
• context (optional) bind new context with callback function.

Returns: array array.

Examples:

// array to loop over
var array = [ 1, "a", [ 3 ] ];

_z.for( array, function(index, value) {
// log the value if its a number.
    if( _z.isNumber(value) ) console.log(value);

    console.log( this ); // value
});

// change callback context loop
var contextToAttach = [ 1234, "second argument" ];

// element/s to loop over
_z("input").for(function( index, element ) {
// index = element index;
// element = element;

    console.log( this ); // [ 1234, "second argument" ]
}, contextToAttach);

// loop and change values
var lArray = [4, 1, "a", 100, 2, 3];
_z.for(lArray, function() {
    if( _z.isNumber(this) && this > 2 )
        return "replaced element - " + this;
}); // ["new value - 4", 1, "a", "new value - 100", 2, "new value - 3"]
