如何对悬停在元素上后变为可见的元素执行单击事件.下面是HTML代码

<div class="jqtree-element jqtree_common">
<span class="jqtree-title jqtree_common" contenteditable="true">Notebook 1</span>
<span class="notebook-right">
<span class="notebook-date disappear" style="visibility: visible;">
<span class="notebook-commands-right">
<span class="notebook-commands appear-wrapper">
<span class="notebook-commands appear" style="display: none;">
<span class="fontawesome-button info">
<span class="fontawesome-button history">
<span class="fontawesome-button private">
<span class="fontawesome-button public" style="display: none;">
<span class="fontawesome-button remove">
<i class="icon-remove"></i>
</span>
</span>
</span>
</span>
</div>

删除笔记本我正在使用以下代码

casper.then(function(){
  if(this.visible({type:'xpath', path:'/html/body/div[3]/div/div[1]/div[1]/div/div/div[1]/div[2]/div/div/ul/li[1]/ul/li[1]/ul/li[11]/div/span[2]/span[3]/span/span[5]/i'}))
  {
    this.click({type:'xpath', path:'/html/body/div[3]/div/div[1]/div[1]/div/div/div[1]/div[2]/div/div/ul/li[1]/ul/li[1]/ul/li[11]/div/span[2]/span[3]/span/span[5]/i'});
    });
    console.log('notebook '+ title +' deleted');
  } else {
     console.log('element not found');
  }
});

在控制台中显示"无法调度mousedown事件.."
