本文关键字：选择器 查找 元素 何消 错误      更新时间：2023-09-26

我正在尝试使用Angularstap.js制作弹出窗口。我从这里阅读文档http://mgcrea.github.io/angular-strap/##popovers但我的pop over不显示点击你能告诉我我做错了。这是我的活塞http://plnkr.co/edit/Cp7wrpeh8SS4oY5GGRfY?p=preview

出现错误:错误:[jqLite:nosel] jqLite不支持通过选择器查找元素!看:

<!DOCTYPE html>
<html ng-app="myApp">
  <head>
    <link data-require="bootstrap-css@3.x" data-semver="3.2.0" rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" />
    <script data-require="angular.js@*" data-semver="1.3.0-beta.5" src="https://code.angularjs.org/1.3.0-beta.5/angular.js"></script>
    <script data-require="ui-bootstrap@0.10.0" data-semver="0.10.0" src="http://angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.10.0.js"></script>
    <link rel="stylesheet" href="style.css" />
    <script src="script.js"></script>
        <script src="https://dl.dropboxusercontent.com/s/64qidru3z31h5ns/angular-strap.js"></script>
        <script src="https://dl.dropboxusercontent.com/s/meplmw59rwg2dmy/angular-strap.tpl.js?m=d"></script>
        <script src="https://dl.dropboxusercontent.com/s/qhgexynaog5ul5l/popover.js"></script>
  </head>
  <body>
<button type="button" class="btn btn-lg btn-danger" title="this" data-content="{{popover.content}}" data-template="pop.html" data-animation="am-flip-x" bs-popover>Custom Popover

</button>  </body>
<script>
  var myapp =angular.module('myApp', ['mgcrea.ngStrap']);
</script>
</html>

实际上，文档已经提到了template属性，但是很难注意到:

应该是div。popover元素遵循Bootstrap样式约定。

因此你的pop.html应该有这样的结构:

<div class="popover">
  <div class="arrow"></div>
  <h3 class="popover-title" ng-bind="title" ng-show="title"></h3>
  <div class="popover-content">
    <ul class="list-group">
        <li class="list-group-item" ng-click="hidePopover();editRowName(student)">Edit</li>
        <li class="list-group-item " ng-click="deleteRow($index)">Delete</li>
    </ul>
  </div>
</div>
