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.

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: ')';
}

这个解决方案纯粹是在HTML上使用ng标签。

解决方案是使用“show more…”限制显示的长文本。链接。如果用户点击“显示更多…”链接，它将显示其余的文本，并删除了“show more…”的链接。

HTML:

<div ng-init="limitText=160">
   <p>{{ veryLongText | limitTo: limitText }} 
       <a href="javascript:void(0)" 
           ng-hide="veryLongText.length < limitText" 
           ng-click="limitText = veryLongText.length + 1" > show more..
       </a>
   </p>
</div>

可以使用筛选器限制字符串或数组的长度。看看AngularJS团队写的这个。

对我来说还行 'In span'， ng-show = "MyCtrl.value.$viewValue. "长度> your_limit"…阅读更多。“结束时间”

<div>{{modal.title | slice: 0: 20}}</div>
