JS forEach和Jquery each

$(function () {
var sss = [3, 2, 1, 4, 5];
$.each(sss, function (i, o) {
if (o > 1) {
document.writeln(o);
}
else {
return false; //相当于break
return;//相当于continue
}
})
})

ECMAScript5中添加的forEach如果要提前终止需要用包括在try catch中

var sss = [3, 2, 1, 4, 5];
try {
sss.forEach(function (o) {
if (o > 1) {
document.writeln(o);
}
else {
throw "asdasd";
}
})
} catch (e) {
document.writeln(e.toString())
}
