Question

我已应用此方法，效果很好。

<input type="text" onkeypress='return event.charCode >= 48 &&    event.charCode <= 57'>
    </input>

当用户尝试其他输入而不是数字时，它是否有可能发出警告信息。非常感谢帮助或建议。谢谢

检查this代码：

//HTML

<div ng-app>
  <div class=" header-row">
    <div class="col">Name</div>
    <div class="col">Sports</div>
    <div class="col">Score</div>
  </div>
  <div ng-controller="TodoCtrl">
    <div class="row" ng-repeat="rows in chunkedData">
      <div class="span4" ng-repeat="item in rows">
        <span class="col">{{item.name}}</span>
        <span class="col">{{item.sport}}</span>
        <span class="col">{{item.score}}</span>
      </div>
    </div>
  </div>
</div>


//Script

function TodoCtrl($scope) {
  $scope.data = [
    {
      name : '0',
      sport: 'Cricket',
      score: 89
    },
    {
      name : '1',
      sport: 'Cricket',
      score: 89
    },
    {
      name : '2',
      sport: 'Cricket',
      score: 89
    },
    {
      name : '3',
      sport: 'Cricket',
      score: 89
    },
    {
      name : '4',
      sport: 'Cricket',
      score: 89
    },
    {
      name : '5',
      sport: 'Cricket',
      score: 89
    },
    {
      name : '6',
      sport: 'Cricket',
      score: 89
    }
  ];
  $scope.chunkedData = chunk($scope.data, 3);
  function chunk(arr, size) {
    var newArr = [];
    for (var i=0; i<arr.length; i+=size) {
      newArr.push(arr.slice(i, i+size));
    }
    return newArr;
  }
}

//CSS

.col{
  display: inline-block;
  width:70px;
  float: left;
  padding: 3px;
}
.header-row{
  width: 100%;
  background-color: #000;
  color: #fff;
  overflow: hidden;
  padding: 3px;
}
.row{
  overflow: hidden;
  display: inline-block;
  float: left; 
  border: 1px solid grey;
}
