在jquery/javascript的陈述中,核对多个数值
原标题:check multiple values in an if statement in jquery/javascript

我试图通过下列方式使投入箱的价值空白:

var id = $(this).attr( id ).substr(3);
var lengthname = $("#input_name_"+id).val().length;
var lengthrss = $("#input_rss_"+id).val().length;
if (lengthrss!=0 || lengthname!=0)
{
  // do something
}
else
{
alert( Values cannot be blank );
}

但由于某种原因,如果用户作为灯塔进入这两个数值,那么警报就会发出吗?

最佳回答

你们所期望的是行动,而不是行动。 有效的情况是 限值均为非零:

if (lengthrss!=0 && lengthname!=0)
{
  // do something
}

或者:

if (lengthrss==0 || lengthname==0)
{
  alert( Values cannot be blank );
}

参考:
