无法在angularjs中过滤罗马数字

Question

我无法在angularjs中过滤罗马数字。我有四个用于搜索的输入区域，图像如下：

选择班级'I'后： -

结果：

Name  Class 
-----------
xyz     I
abc     II
ebc     VI

接受： -

Name   Class
-------------
xyz     I

代码：

模型是 ng-model =“searchClass”

<tr ng-repeat="defaulterList in defaulterLists| filter:searchText | filter:searchClass | filter:searchSection | filter:horsepowerFilter">

即使我尝试使用过滤器中的属性，例如 filter：searchClass.class 但不能正常工作

过滤代码：

     <tr ng-repeat="defaulterList in defaulterLists| filter:searchText | filter:searchClass | filter:searchSection | filter:horsepowerFilter">
           <td>{{$index + 1}}</td>
           <td>{{defaulterList.admno}}</td>
           <td>{{defaulterList.name}}</td>
           <td>{{defaulterList.mobile_no}}</td>
           <td>{{defaulterList.class}}</td>
           <td>{{defaulterList.section}}</td>
           <td>{{defaulterList.total}}</td>
           <td><select ng-model="defaulterList.msgid" class="full-width"> <option value="">-select-</option><option ng-repeat="message in messages" value="{{message.id}}">{{message.title}}</option></select></td>
           <td><button class="btn-success btn-small" ng-click="sendSms(defaulterList)">Send SMS</button></td>

        </tr>

Answer 1

试试这个

$scope.data = {};
$scope.data.defaulterLists = $scope.defaulterLists;

并将searchText更改为$scope.data.searchText。它现在应该工作。

使用ng-repeat作为

<tr ng-repeat="defaulterList in data.defaulterLists| filter:data.searchText | filter:data.searchClass | filter:data.searchSection | filter:data.horsepowerFilter">

我遇到了同样的问题。

只需更改

过滤器：searchClass

到

过滤器：searchClass：真

Answer 3

$scope.romanize = function(num){
        if (!+num)
            return false;
        var digits = String(+num).split(""),
            key = ["","C","CC","CCC","CD","D","DC","DCC","DCCC","CM",
                   "","X","XX","XXX","XL","L","LX","LXX","LXXX","XC",
                   "","I","II","III","IV","V","VI","VII","VIII","IX"],
            roman = "",
            i = 3;
        while (i--)
            roman = (key[+digits.pop() + (i * 10)] || "") + roman;
        return Array(+digits.join("") + 1).join("M") + roman;
    }
