我创建了这个指令，很容易做到这一点，截断字符串到指定的限制，并添加了一个“显示更多/更少”切换。你可以在GitHub上找到它:https://github.com/doukasd/AngularJS-Components

它可以这样使用:

<p data-dd-collapse-text="100">{{veryLongText}}</p>

下面是指令:

// a directive to auto-collapse long text
app.directive('ddCollapseText', ['$compile', function($compile) {
return {
    restrict: 'A',
    replace: true,
    link: function(scope, element, attrs) {

        // start collapsed
        scope.collapsed = false;

        // create the function to toggle the collapse
        scope.toggle = function() {
            scope.collapsed = !scope.collapsed;
        };

        // get the value of the dd-collapse-text attribute
        attrs.$observe('ddCollapseText', function(maxLength) {
            // get the contents of the element
            var text = element.text();

            if (text.length > maxLength) {
                // split the text in two parts, the first always showing
                var firstPart = String(text).substring(0, maxLength);
                var secondPart = String(text).substring(maxLength, text.length);

                // create some new html elements to hold the separate info
                var firstSpan = $compile('<span>' + firstPart + '</span>')(scope);
                var secondSpan = $compile('<span ng-if="collapsed">' + secondPart + '</span>')(scope);
                var moreIndicatorSpan = $compile('<span ng-if="!collapsed">...</span>')(scope);
                var toggleButton = $compile('<span class="collapse-text-toggle" ng-click="toggle()">{{collapsed ? "less" : "more"}}</span>')(scope);

                // remove the current contents of the element
                // and add the new ones we created
                element.empty();
                element.append(firstSpan);
                element.append(secondSpan);
                element.append(moreIndicatorSpan);
                element.append(toggleButton);
            }
        });
    }
};
}]);

和一些CSS去它:

.collapse-text-toggle {
font-size: 0.9em;
color: #666666;
cursor: pointer;
}
.collapse-text-toggle:hover {
color: #222222;
}
.collapse-text-toggle:before {
content: '\00a0(';
}
.collapse-text-toggle:after {
content: ')';
}

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

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.

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

编辑 AngularJSoffers的最新版本的limitTo过滤器。

你需要一个这样的自定义过滤器:

angular.module('ng').filter('cut', function () {
        return function (value, wordwise, max, tail) {
            if (!value) return '';

            max = parseInt(max, 10);
            if (!max) return value;
            if (value.length <= max) return value;

            value = value.substr(0, max);
            if (wordwise) {
                var lastspace = value.lastIndexOf(' ');
                if (lastspace !== -1) {
                  //Also remove . and , so its gives a cleaner result.
                  if (value.charAt(lastspace-1) === '.' || value.charAt(lastspace-1) === ',') {
                    lastspace = lastspace - 1;
                  }
                  value = value.substr(0, lastspace);
                }
            }

            return value + (tail || ' …');
        };
    });

用法:

{{some_text | cut:true:100:' ...'}}

选项:

Wordwise (boolean) -如果为真，仅按单词边界切割， Max (integer) -文本的最大长度，切到这个字符数， Tail (string，默认值:'…')-将此字符串添加到输入 如果绳子被剪断，就用绳子。

另一个解决方案:http://ngmodules.org/modules/angularjs-truncate (by @Ehvince)

这可能不是来自脚本末尾，但你可以使用下面的css并将这个类添加到div中。这将截断文本，并在鼠标悬停时显示全文。你可以添加更多的文本，并添加一个角点击手柄来改变cli上的div类

.ellipseContent {
    overflow: hidden;
    white-space: nowrap;
    -ms-text-overflow: ellipsis;
    text-overflow: ellipsis;
}

    .ellipseContent:hover {
        overflow: visible;
        white-space: normal;
    }
