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>

其他回答

我知道这有点晚了，但在angularjs的最新版本(我使用的是1.2.16)中，limitTo过滤器支持字符串和数组，所以你可以像这样限制字符串的长度:

{{ "My String Is Too Long" | limitTo: 9 }}

它将输出:

My String

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();
        }

    };

你可以简单地在div中添加一个css类，并通过angularjs添加一个工具提示，这样鼠标移过去时就可以看到修剪后的文本。

< div class = " trim-info“工具提示= " {{modal.title}} > {{modal.title}} < / div > .trim-info { max-width: 50 px; 显示:inline-block; 溢出:隐藏; 文本溢出:省略; 空白:nowrap;} 行高:15 px; 位置:相对; ｝

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

使用自定义Angular过滤器限制字数: 下面是我如何使用Angular过滤器来限制使用自定义过滤器显示的字数。

HTML:

<span>{{dataModelObject.TextValue | limitWordsTo: 38}} ......</span>

角/ Javascript代码

angular.module('app')
.filter('limitWordsTo', function () {
    return function (stringData, numberOfWords) {
        //Get array of words (determined by spaces between words)
        var arrayOfWords = stringData.split(" ");

        //Get loop limit
        var loopLimit = numberOfWords > arrayOfWords.length ? arrayOfWords.length : numberOfWords;

        //Create variables to hold limited word string and array iterator
        var limitedString = '', i;
        //Create limited string bounded by limit passed in
        for (i = 0; i < loopLimit; i++) {
            if (i === 0) {
                limitedString = arrayOfWords[i];
            } else {
                limitedString = limitedString + ' ' + arrayOfWords[i];
            }
        }
        return limitedString;
    }; 
}); //End filter
