Ext.each的用法

each : function(array, fn, scope)...{

if(Ext.isEmpty(array, true))...{

return;

}

if(!Ext.isIterable(array) || Ext.isPrimitive(array))...{

array = [array];

}

for(var i = 0, len = array.length; i < len; i++)...{

if(fn.call(scope || array[i], array[i], i, array) === false)...{//3等号

return i;

};

}

}

		

  var people = ['Bill', 'Saul', 'Gaius'];

 

//using each to detect Cylons:

 var f=function (person, index)

...{

    var cylon = (index + 1) % 2 == 0; //every second man is a toaster

    alert(person + (cylon ? ' is ' : ' is not ') + 'a fraking cylon');

}

Ext.each(people,f);

		

//JS数组

Ext.each([1,0,3,4,5,6,8],function(item)...{alert(item)});

 
//JS数组里JSON对象
Ext.each([...{name:"cola",age:27},...{name:"moka",age:28}],function(item)...{alert(item.name)});
