javascript - How can i get link from MSO code via javascript

问题描述

I have lots of links in my code. I got all links from code but which links are presented in the MSO code I didn't get those links. In MSO code there is no <a> tag that's why it's hard for me to select the link. I have tried with document.querySelectorAll("[href]");. It's not working. Can anyone please help me here that how can I get links from MSO code 

let links = document.querySelectorAll("[href]");

for(let link of links)
{
  let curhref = link.href;
  if(curhref.indexOf('http') > -1)
  {
    link.href = curhref.replace(/(\?|&)elqTrackId=[a-z0-9]+(&elqTrack=true)?/, '');
    if(link.href.indexOf('ea=') > -1)
    {
      link.href += '&utm_source=iconnect&utm_medium=email&utm_campaign={{Approved_Document_vod__c.Vault_Document_ID_vod__c}}&emailId={{Approved_Document_vod__c.Vault_Document_ID_vod__c}}&codsId={{Account.CODS_External_Id__c}}&utm_term=';
    }
    else
    {
      link.href += '?utm_source=iconnect&utm_medium=email&utm_campaign={{Approved_Document_vod__c.Vault_Document_ID_vod__c}}&emailId={{Approved_Document_vod__c.Vault_Document_ID_vod__c}}&codsId={{Account.CODS_External_Id__c}}&utm_term=';
    }
  }
}

解决方案

你是说里面的碎片<!--[if mso]…… [endif]-->？

在 HTML 中，<!--开始一个注释块。

并-->结束一个评论块。

这些标签中的任何内容都被视为注释，并且不是 DOM 的一部分，因此 JavaScript 看不到它。

一些额外的背景：<!--[if mso]...[endif]-->语法是 Microsoft 特定的代码，称为条件注释。呈现 HTML 的 Microsoft 应用程序（包括 Internet Explorer 和 Outlook）可以读取这些并将它们解释为代码，然后，如果满足条件，会将这些块之间的内容呈现到 DOM 中。但是，对于所有其他浏览器/渲染器来说，除了标准的注释标签之外，它们毫无意义，因此被视为注释。即使在 Microsoft 应用程序中，条件注释现在也是一项遗留功能，随着渲染引擎获得对 Web 标准的更好支持，它的必要性越来越少。

在这种情况下，mso指的是 Microsoft Outlook，因此只有在 Outlook 中查看 HTML 时才会呈现此内容。
