jquery $.each 和for怎么跳出循环终止本次循环

1、for循环中我们使用continue；终止本次循环计入下一个循环，使用break终止整个循环。 
2、而在jquery中 $.each则对应的使用return true 和return false。

eg:

<script>

$(function(){
    for(var i=0;i<10;i++){
        if(i%2==0)continue;
        if(i==7)break;
        document.write(i+"<br>");
    }
    var json = [
    {"id":"1","tagName":"11"},
    {"id":"2","tagName":"22"},
    {"id":"3","tagName":"33"},
    {"id":"4","tagName":"44"},
    {"id":"5","tagName":"55"},
    {"id":"6","tagName":"66"},
    {"id":"7","tagName":"77"},
    {"id":"8","tagName":"88"}
];
 
$.each(json, function(idx, obj) {
    if(obj.id%2==0)return true;
    if(obj.id==7)return false;
    document.write(obj.tagName+"<br>");
});
});
</script>
