请问各位，关于js Unexpected token ILLEGAL的问题

var template = 
  '<div class="m-modal">\
    <div class="modal_align"></div>\
    <div class="modal_wrap animated">\
      <div class="modal_head">标题</div>\
      <div class="modal_body">内容</div>\
      <div class="modal_foot">\
        <a class="confirm" href="#">确认</a>\
        <a class="cancel" href="#">取消</a>\
      </div>\
    </div>\
  </div>';

我这样定义了一段变量是正确的
可是再定义一个这样的就错了

var template='<div class="m-modal">
      <div class="modal_align"></div>
      <div class="modal_wrap">
        <div class="bk"></div>
        <div class="modal_body">
          <h3>登录网易云课堂</h3>
          <div class="form1">
            <input value="账号">
          </div>
          <div class="form2">
            <input value="密码">
          </div>
          <button class="submit">登录</button>
        </div>
        
      </div>
      <div class="bk"></div>
    </div>'
