问题描述

我正在使用ng-options来迭代选择框中的选项，这是下面的代码..

I am using ng-options to iterate options in select box , Here is my code below ..

<select id="multiSelectAvailable" ng-model="selected.available" multiple 
        ng-options="e as e[displayAttr] for e in available"></select>

将鼠标悬停在选项上时如何显示displayAttr的工具提示?

How to show a tooltip of displayAttr when hover on options?

推荐答案

可以通过jquery工具提示对选择选项进行工具提示.

Tool tip over select options is possible through jquery tooltip.

具有自定义指令.

angular.module('ui.bootstrap.demo').directive('myDirec', ['$log', '$templateCache', '$compile', function($log, $templateCache, $compile) {
  return {
    restrict: 'A',
    priority: 1000,

    link: function(scope, element, attr) {
            element.children().attr('data-toggle', 'tooltip');
            element.children().attr('data-placement', 'tooltip');
            element.children().attr('title', 'hello tool tip');

      $compile(element)(scope);
    },
  };
}]);

和

<select my-direc ng-model="select" multiple data-toggle="tooltip" data-placement="top" title="{{e.toolTip}}"
        ng-options="e as e.tableName for e in data"></select>

更新的Plunker 链接相同.

Updated Plunker link for the same.

尝试一下，

在app.js中，

angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('TooltipDemoCtrl', function ($scope, $sce) {
  $scope.dynamicTooltip = 'Hello, World!';
  $scope.dynamicTooltipText = 'dynamic';
  $scope.htmlTooltip = $sce.trustAsHtml('I\'ve been made <b>bold</b>!');
   $scope.data = [{
      id: 1,
      tableName: 'table1',
      toolTip:'tool tip 1'
    }, {
      id: 2,
      tableName: 'table2',
      toolTip:'tool tip 2'
    }, {
      id: 3,
      tableName: 'table3',
      toolTip:'tool tip 3'
    }];
});
angular.module('ui.bootstrap.demo').directive('myDirec', ['$log', 
'$templateCache', '$compile', function($log, $templateCache, $compile) {
  return {
    restrict: 'A',
    priority: 1000,

    link: function(scope, element, attr) {
            element.children().attr('data-toggle', 'tooltip');
            element.children().attr('data-placement', 'tooltip');
            element.children().attr('title', 'hello tool tip');

      $compile(element)(scope);
    },
  };
}]);

在HTML中，

<html ng-app="ui.bootstrap.demo">
  <head>
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.js"></script>
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular-animate.js"></script>
    <script src="//angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.13.4.js"></script>
    <script src="example.js"></script>
    <link href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet">
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">


  </head>
  <body ng-controller="TooltipDemoCtrl">

       <select  ng-model="select" >
          <option data-toggle="tooltip" data-placement="top" title="{{item.toolTip}}"  ng-repeat="item in data">{{item.tableName}}</option> 
       </select>

  </body>
</html>
