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

下面是一个用于截断文本的自定义过滤器。它的灵感来自于EpokK的解决方案，但根据我的需求和口味进行了修改。

angular.module('app').filter('truncate', function () {

    return function (content, maxCharacters) {

        if (content == null) return "";

        content = "" + content;

        content = content.trim();

        if (content.length <= maxCharacters) return content;

        content = content.substring(0, maxCharacters);

        var lastSpace = content.lastIndexOf(" ");

        if (lastSpace > -1) content = content.substr(0, lastSpace);

        return content + '...';
    };
});

这里是单元测试，所以你可以看到它应该如何表现:

describe('truncate filter', function () {

    var truncate,
        unfiltered = " one two three four ";

    beforeEach(function () {

        module('app');

        inject(function ($filter) {

            truncate = $filter('truncate');
        });
    });

    it('should be defined', function () {

        expect(truncate).to.be.ok;
    });

    it('should return an object', function () {

        expect(truncate(unfiltered, 0)).to.be.ok;
    });

    it('should remove leading and trailing whitespace', function () {

        expect(truncate(unfiltered, 100)).to.equal("one two three four");
    });

    it('should truncate to length and add an ellipsis', function () {

        expect(truncate(unfiltered, 3)).to.equal("one...");
    });

    it('should round to word boundaries', function () {

        expect(truncate(unfiltered, 10)).to.equal("one two...");
    });

    it('should split a word to avoid returning an empty string', function () {

        expect(truncate(unfiltered, 2)).to.equal("on...");
    });

    it('should tolerate non string inputs', function () {

        expect(truncate(434578932, 4)).to.equal("4345...");
    });

    it('should tolerate falsey inputs', function () {

        expect(truncate(0, 4)).to.equal("0");

        expect(truncate(false, 4)).to.equal("fals...");
    });
});

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',[])

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

我发现限制字符串长度的最简单的解决方案是{{modal。title | slice:0:20}}，然后借用上面的@Govan，你可以使用{{modal.title.length > 20 ?“…': "}}如果字符串长于20，则添加挂起点，因此最终结果很简单:

{{模态。Title | slice:0:20}}{{modal.title.length > 20 ?“…': "}}
