在html中，它与angular自身提供的limitTo过滤器一起使用，如下所示:

    <p> {{limitTo:30 | keepDots }} </p>

filter keepDots:

     App.filter('keepDots' , keepDots)

       function keepDots() {

        return function(input,scope) {
            if(!input) return;

             if(input.length > 20)
                return input+'...';
            else
                return input;

        }

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.

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',[])

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

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
