Question

这是我的油脂脚本。我想在每次打开reddit页面时自动触发它。我想要 function up_vote_all（）{ vote_all（'向上箭头'）; }

在没有我点击菜单项的情况下自动触发每个页面。感谢

   // ==UserScript==
// @name          Reddit Mass Vote
// @namespace     http://reddit.com
// @description   You can up vote or down vote all comments on any page instantly without having to click each arrow. This is mainly to be used against spammers and trolls.

GM_registerMenuCommand('Up Vote All', up_vote_all);


// From http://snipplr.com/view/1696/get-elements-by-class-name/
function getElementsByClassName(classname, node)  {
  if(!node) node = document.getElementsByTagName("body")[0];
  var a = [];
  var re = new RegExp('\\b' + classname + '\\b');
  var els = node.getElementsByTagName("*");
  for(var i=0,j=els.length; i<j; i++)
    if(re.test(els[i].className))a.push(els[i]);
  return a;
}

// From http://jehiah.cz/archive/firing-javascript-events-properly
function fireEvent(element,event){
  if (document.createEventObject){
    // dispatch for IE
    var evt = document.createEventObject();
    return element.fireEvent('on'+event,evt);
  }
  else {
    // dispatch for firefox + others
    var evt = document.createEvent("HTMLEvents");
    evt.initEvent(event, true, true ); 
    return !element.dispatchEvent(evt);
  }
}


function up_vote_all() {
  vote_all('arrow up');
}


function vote_all(class_name) {
  arrows = getElementsByClassName(class_name);
  for (var i = 0; i < arrows.length; i++) {
      fireEvent(arrows[i], 'click');
  }
}

我找到了，我需要在开头插入此命令

document.addEventListener("DOMContentLoaded", function() {
  up_vote_all();
});

很容易。
