使用AngularJS限制字符串的长度

我有以下几点:

<div>{{modal.title}}</div>

有没有一种方法可以限制字符串的长度，比如20个字符?

一个更好的问题是，有没有一种方法可以将字符串更改为截断并显示。如果超过20个字符?

当前回答

ng-keypress = " filterValue(事件)”ng-model = "客户。CUSTOMER_PHONE”

美元的范围。filterValue = function($event){

        if(isNaN(String.fromCharCode($event.keyCode)) ){
            $event.preventDefault();
        }
        if($scope.customer.CUSTOMER_PHONE.length <= 11)
        {              
            $scope.customer.CUSTOMER_PHONE = $scope.customer.CUSTOMER_PHONE;
        }
        else
        {
            $event.preventDefault();
        }

    };

其他回答

由于只在字符串长度超过限制时才需要省略号，因此使用ng-if添加省略号似乎比使用绑定更合适。

{{ longString | limitTo: 20 }}<span ng-if="longString.length > 20">&hellip;</span>

<div>{{modal.title | slice: 0: 20}}</div>

有一个选择

.text { max-width: 140px; white-space: nowrap; overflow: hidden; padding: 5px; text-overflow: ellipsis;(...) } <div class="text">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Excepturi qui soluta labore! Facere nisi aperiam sequi dolores voluptatum delectus vel vero animi, commodi harum molestias deleniti, quasi nesciunt. Distinctio veniam minus ut vero rerum debitis placeat veritatis doloremque laborum optio, nemo quibusdam ad, sed cum quas maxime hic enim sint at quos cupiditate qui eius quam tempora. Ab sint in sunt consequuntur assumenda ratione voluptates dicta dolor aliquid at esse quaerat ea, veritatis reiciendis, labore repellendus rem optio debitis illum!

如果你想要这样的东西:InputString => StringPart1…StringPart2

HTML:

<html ng-app="myApp">
  <body>
    {{ "AngularJS string limit example" | strLimit: 10 : 20 }}
  </body>
</html>

角代码:

 var myApp = angular.module('myApp', []);

 myApp.filter('strLimit', ['$filter', function($filter) {
   return function(input, beginlimit, endlimit) {
      if (! input) return;
      if (input.length <= beginlimit + endlimit) {
          return input;
      }

      return $filter('limitTo')(input, beginlimit) + '...' + $filter('limitTo')(input, -endlimit) ;
   };
}]);

参数示例如下: beginLimit = 10 endLimit = 20
