代码如下:
Array.prototype.each = function(fn)
{
return this.length ? [fn(this.slice(0,1))].concat(this.slice(1).each(fn)) : [];
};
[1,2,3,4].each(function(x){
document.write(x + "
");
});
为原生jsArray增加each方法_javascript技巧
Array.prototype.each = function(fn)
{
return this.length ? [fn(this.slice(0,1))].concat(this.slice(1).each(fn)) : [];
};
[1,2,3,4].each(function(x){
document.write(x + "
");
});
