我有一个框架生成这个无线电,如何更新标签whithout id但"for"属性的"asa"文本？

<input type="radio" value="questao1" id="SimuladoQuestao1">
        <label for="SimuladoQuestao1">asa</label>

谢谢,塞尔索.

如何访问每个内部的值

for(var int = 1; int <5; int ++)

？

谢谢,塞尔索

我是Maps API中的新手,我正在尝试从2地址获取距离(以公里为单位).这段代码有什么问题？

var mygc = new google.maps.Geocoder();

var locationOrigem;
var locationDestino;

var latOrigem  = 0;
var longOrigem = 0;

var latDestino  = 0;
var longDestino = 0;


mygc.geocode({'address' : 'Presidente Vargas 897, Centro RJ'}, function(results, status){

    locationOrigem = results[0].geometry.location;
    latOrigem   = results[0].geometry.location.lat();
    longOrigem  = results[0].geometry.location.lng();

});

mygc.geocode({'address' : 'Abelardo Bueno 3000, Barra da Tijuca RJ'}, function(results, status){

    locationDestino = results[0].geometry.location;
    latDestino  = results[0].geometry.location.lat();
    longDestino = results[0].geometry.location.lng();

});

alert(google.maps.geometry.spherical.computeDistanceBetween(locationOrigem, locationDestino));

由于一个未知的原因,var locationOrigem和locationDestino在匿名函数之外是"未定义的"??? 为什么？？？

出于性能目的，我尝试使用管道将一组正则表达式转换为仅一个。
