如何在 jQuery 选择器中分配 onclick 函数的变量值

Question

基本上，我想要一个特定的 div 部分在单击锚点后显示（显示）它的内容。如果该部分的元素标题与按钮标题匹配，则该部分必须仅显示内容。

这里是 HTML 代码：

<a href="#accordion" id="my-link" class="btn btn-primary">Open group 2</a>
<br/>
<a href="#accordion" id="my-link2" class="btn btn-primary">Communications</a>
<br/><br/><br/><br/>
<div class="panel-group" id="accordion">
  <div class="panel panel-default" id="panel1">
    <div class="panel-heading">
      <h4 class="panel-title">
        <a data-toggle="collapse" data-parent="#accordion" href="#collapseOne">
          Section with the title of "Communications" in the div element
        </a>
      </h4>
    </div>
    <div id="collapseOne" class="panel-collapse collapse in" title="Communications">
      <div class="panel-body">
        Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch.

      </div>
    </div>
  </div>
  <div class="panel panel-default" id="panel2">
    <div class="panel-heading">
      <h4 class="panel-title">
        <a data-toggle="collapse" data-parent="#accordion" href="#collapseTwo">
          Collapsible Group Item #2
        </a>
      </h4>
    </div>
    <div id="collapseTwo" class="panel-collapse collapse">
      <div class="panel-body">
        Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch. Food truck quinoa nesciunt laborum eiusmod. Brunch 3 wolf moon tempor, sunt aliqua put a bird on it squid single-origin coffee nulla assumenda shoreditch et. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt sapiente ea proident. Ad vegan excepteur butcher vice lomo.

      </div>
    </div>
  </div>
  
</div>

通常情况下，此脚本可以正常工作：

$('#my-link2').click(function(e) {
    var currentAnchor = $(this);
    alert(currentAnchor.text());
    $("[title*='Communications']").collapse('show');
    $('#collapseTwo').collapse('hide');        
});

但是当使用下面的代码行时，它似乎不起作用:

$('#my-link2').click(function(e) {
    var currentAnchor = $(this);
    alert(currentAnchor.text());
    $("[title*='" + currentAnchor() + "']").collapse('show'); <-- I think i'm doing something wrong here
    $('#collapseTwo').collapse('hide');        
});

要对其进行测试，请参考此 jsfiddle：http://jsfiddle.net/tomanow/DSGxz/632/ 并使用上述示例更改 HTML 和脚本。

在此先感谢您，感谢我能得到的任何帮助。

Answer 1

如果您检查浏览器的 JS 控制台，您将看到以下错误：

尝试使用元素的内部文本：

$('#my-link2').click(function(e) {
    var currentAnchor = $(this);
    alert(currentAnchor.text());
    $("[title*='" + currentAnchor.text() + "']").collapse('show');
    $('#collapseTwo').collapse('hide');        
});

Answer 2

通过对按钮进行一些小的修改，添加一个 class 和一个数据属性，您可以为整个 class 个按钮做一个更通用的监听器。

类似于：

HTML

<a href="#accordion" id="my-link" data-panel="2" class="btn btn-primary mytoggle-btn">Open group 2</a>

JS

$('.mytoggle-btn').click(function(e) {
    var $panel = $('#panel' + $(this).data('panel')),
        $content = $panel.find('.panel-collapse');
    // collapse other panels
    $('#accordion .panel-collapse').not($content).collapse('hide');
    // show the associated on to this button instance        
    $content.collapse('show');        
});
