只需在脚本中添加以下代码片段:

    $(function () {
        $('[data-toggle="tooltip"]').tooltip()
    });

当然如上所述，data-html的答案应该是“真”。这将允许您在title属性的值内使用html标记和格式。

我找到了。只要这样简单地做就可以了

<a ref="#" title="First Line
                  Second Line
                  Third line">Hover Me</a>

AngularJS with Bootstrap UI Tolltip (uib-tooltip), has three versions of tool-tip:

Uib-tooltip, Uib-tooltip -template和Uib-tooltip -html

- uib-tooltip takes only text and will escape any HTML provided
- uib-tooltip-html takes an expression that evaluates to an HTML string
- uib-tooltip-template takes a text that specifies the location of the template

在我的情况下，我选择了uib-tooltip-html，有三个部分:

配置 控制器 超文本标记语言

例子:

(function(angular) {

//Step 1: configure $sceProvider - this allows the configuration of $sce service.

angular.module('myApp', ['uib.bootstrap'])
       .config(function($sceProvider) {
           $sceProvider.enabled(false);
       });

//Step 2: Set the tooltip content in the controller

angular.module('myApp')
       .controller('myController', myController);

myController.$inject = ['$sce'];

function myController($sce) {
    var vm = this;
    vm.tooltipContent = $sce.trustAsHtml('I am the first line <br /><br />' +
                                         'I am the second line-break');

    return vm;
}

 })(window.angular);

//Step 3: Use the tooltip in HTML (UI)

<div ng-controller="myController as get">
     <span uib-tooltip-html="get.tooltipContent">other Contents</span>
</div>

如果你使用jquery-ui 1.11.4:

var tooltip = $.widget( "ui.tooltip", {
    version: "1.11.4",
    options: {
        content: function() {
            // support: IE<9, Opera in jQuery <1.7
            // .text() can't accept undefined, so coerce to a string
            var title = $( this ).attr( "title" ) || "";
            // Escape title, since we're going from an attribute to raw HTML
Replace-->  //return $( "<a>" ).text( title ).html();
by -->      return $( "<a>" ).html( title );
             },

Jquery UI 1.10不支持在标题属性中使用html标签，因为它不是有效的html。

所以另一种解决方案是使用工具提示内容选项。 参考- http://api.jqueryui.com/tooltip/#option-content

您可以使用引导工具提示，不要忘记将html选项设置为true。

<div id="tool"> tooltip</div>

$('#tool').tooltip({
     title: 'line one' +'<br />'+ 'line two',
     html: true
});
