怎样取这代码里面的变量,然后判断他们是否为空?
var city1 = $("#city").html(); 这样取对不对,感觉取不出来啊!!求指教!


回复讨论(解决方案)

var city1 = $("#city"). val();

另外,没见到加载 jQuery 的代码

你那个取值方法错了 版主已经给你改了 function emptyrules() 这个函数什么时候调用你没有贴出来 有return 的话别忘记在onlick 方法前面加一个return 

if(city1 == " " || person_type1 == " " || province1 == " " || name1 == " " || idcard1 ==" " || person_id1 == " "){
                     alert('请将信息填写完整!');
                     return false;
                     }else{
                     alert(name1);
                     alert('输入正确!');
                     return true;
                     }
                     }


这里面的alert(name1)  在输出时为什么输出的是undefined ?
