javascript - 使用 Javascript mailto 并在 url > 600 个字符时出现错误

Question

我发送电子邮件的方法非常像这样，

function sendMail() 
{     
  var link = "mailto:me@example.com"              
  + "?cc=myCCaddress@example.com"              
  + "&subject=" + escape("This is my subject")              
  + "&body=" + escape(document.getElementById('myText').value);      

  window.location.href = link; 
} 

我正在使用alert(link.length)，每当它超过大约620个字符时，IE选项卡就会“崩溃”，它会给出“此选项卡已恢复”消息，但实际上根本恢复得不好.

这是怎么回事？

似乎有一个限制according to this 。我无法测试以下内容，因为我目前只能访问 Mac，但是您尝试过吗:

function sendMail() 
{     
    var mailForm = document.createElement('form');
    mailForm.id = 'mailForm';
    mailForm.action = 'mailto:user@mailinator.com';
    mailForm.method = 'get';

    var cc = document.createElement('input');
    cc.name = 'cc';
    cc.type = 'hidden';
    cc.value = 'ccUser@mailinator.com';

    var subject = document.createElement('input');
    subject.name = 'subject';
    subject.type = 'hidden';
    subject.value = escape("This is my subject");

    var msgBody = document.createElement('input');
    msgBody.name = 'body';
    msgBody.type = 'hidden';
    msgBody.value = escape(document.getElementById('myText').value);

    mailForm.appendChild(cc);
    mailForm.appendChild(subject);
    mailForm.appendChild(msgBody);
    document.body.appendChild(mailForm);
    document.forms['mailForm'].submit();
}
