如何点击JS中的链接？

  • 772

你好，VK中有这样的链接。

<a class="ui_actions_menu_item" role="link" tabindex="0" onclick="wall.deletePost(this, '395737740_8', 'de6d40183f2070c87e');"></a>

我在一个变量中有这个标识符，395737740_8 我怎样才能使用这个标识符点击这个链接。事实是我的页面上有很多这样的链接，我可以只在这一行选择我需要的链接395737740_8帮助我解决问题。解决方案是在 JavaScript 中。

    let id = '395737740_8';

document.querySelectorAll('.ui_actions_menu_item').forEach(a => a.onclick.toString().includes(`${id}`) ? a.classList.add('yep') : null);
    .yep{
  background: lightcoral;
}
    <a class="ui_actions_menu_item" role="link" tabindex="0" onclick="wall.deletePost(this, '325737740_8', 'de6d40183f2070c87e');">Не то</a><br />

  2. var links = document.getElementsByTagName('a');


function getLinkByClickStr(searchStr) {
  for (var i = 0; i < links.length; i++) {    
      var clickAttr = links[i].getAttribute("onclick");
      if (clickAttr.indexOf("'"+searchStr+"'") != -1) {
        links[i].click();        
        return;
      }        
  }
}

getLinkByClickStr('395737740_8');
    <a class="ui_actions_menu_item" role="link" tabindex="0" onclick="wall.deletePost(this, '395737740_88', 'de6d40183f2070c87e');">test</a>
<a class="ui_actions_menu_item" role="link" tabindex="0" onclick="wall.deletePost(this, '395737740_8', 'de6d40183f2070c87e');">test</a>
<a class="ui_actions_menu_item" role="link" tabindex="0" onclick="wall.deletePost(this, '3957232337740_8', 'de6d40183f2070c87e');">test</a>
