禁用console.log

在脚本中重新定义控制台日志函数

var console={};
console.log=function(){}; // 禁用所有控制台输出

恢复console.log

通过将其拉出iframe，在已删除的页面上恢复console.log

function setConsole() {
  var iframe = document.createElement('iframe');
  iframe.style.display = 'none';
  document.body.appendChild(iframe);
  console = iframe.contentWindow.console;
  window.console = console;
}
setConsole();
