13                 that.bogusInput = container.children[1];
14                 that.bogusInputArr = that.bogusInput.children;//6个Input框
15                 that.maxLength = that.bogusInputArr[0].getAttribute("maxlength");
16                 that.realInput.oninput = function(){
17                     that.setValue();
18                 }
19                 that.realInput.onpropertychange = function(){
20                     that.setValue();
21                 }
22             },
23             setValue:function(){
24                 this.realInput.value = this.realInput.value.replace(/\D/g,"");//\d是数字
25                 var real_str = this.realInput.value;
26                 for(var i = 0 ; i < this.maxLength ; i++){//循环遍历6个获取每个的值；
27                     this.bogusInputArr[i].value = real_str[i]?real_str[i]:"";
28                 }
29                 if(real_str.length >= this.maxLength){//获取前6个
30                     this.realInput.value = real_str.substring(0,6);
31                     this.callback();
32                 }
33             },
34             getBoxInputValue:function(){
35                 var realValue = "";
36                 for(var i in this.bogusInputArr){
37                     if(!this.bogusInputArr[i].value){
38                         break;
39                     }
40                     realValue += this.bogusInputArr[i].value;
41                 }
42                 return realValue;
43             }
44         }
45     })()
46     boxInput.init(function(){
47         getValue();
48     });
49     function getValue(){
50         document.getElementById("showValue").innerText = boxInput.getBoxInputValue();
51     }
