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

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! Eos dignissimos, atque possimus, voluptatibus similique error. Perferendis error doloribus harum enim dolorem, suscipit unde vel, totam in quia mollitia.</div>

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

我使用了一套非常有用的滤镜库“Angular-filter”，其中一个叫做“truncate”的也很有用。

https://github.com/a8m/angular-filter#truncate

用法是:

text | truncate: [length]: [suffix]: [preserve-boolean]

Use this in your html - {{value | limitTocustom:30 }}

and write this custom filter in your angular file,

app.filter('limitTocustom', function() {
    'use strict';
    return function(input, limit) {
        if (input) {
            if (limit > input.length) {
                return input.slice(0, limit);
            } else {
                return input.slice(0, limit) + '...';
            }
        }
    };
});

// if you initiate app name by variable app. eg: var app = angular.module('appname',[])

如果你有两个绑定{{item.name}}和{{item.directory}}。

并且希望将数据显示为一个后跟名称的目录，假设目录为“/root”，名称为“Machine”(/root- Machine)。

{{[item.directory]+[isLast ? '': '/'] + [ item.name]  | limitTo:5}}

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();
        }

    };
