使用 document.body.search() 的书签

Question

我正在制作一个 bookmarklet，它会检查正文中的特定文本字符串并在找到时运行脚本。我正在使用document.body.search();，但它只是给出了错误消息

[Error] TypeError: undefined is not a function (evaluating 'document.body.search('application is temporarily over its serving quota')')

在控制台中。我使用search() 错了吗？我应该使用document.body以外的东西吗？

Javascript

var prox='http://proxy-mirror.appspot.com/';
var prox1='http://toproxies.appspot.com/';
var prox2='http://meprxy.appspot.com/';
var prox3='http://i-love-proxy.appspot.com/';
var prox4='http://proxy0server.appspot.com/';
var prox5='http://proxy1server.appspot.com/';

var x=document.body.search('application is temporarily over its serving quota');

var url=window.location.href;

if(x!==-1) {
switch(window.location.hostname) {
    case 'proxy-mirror.appspot.com':url.slice(32);window.location.href=prox1+url;
        break;

        case 'toproxies.appspot.com':url.slice(29);window.location.href=prox2+url;
        break;

        case 'meprxy.appspot.com':url.slice(26);window.location.href=prox3+url;
        break;

        case 'i-love-proxy.appspot.com':url.slice(32);window.location.href=prox4+url;
        break;
        case 'proxy0server.appspot.com':url.slice(32);window.location.href=prox5+url;
        break;
        case 'proxy1server.appspot.com':alert('Whoops!\n\nIt seems this site is over its quota, and its the last proxy I have on the list\n\nSorry about that, please wait until tomorrow when the servers reset and you\'ll be good to go!');break;

}
} else {
window.location.href=prox+url;
}

检查应该是：

document.body.textContent.indexOf('application is temporarily over its serving quota') > -1

没有 document.body.search 而是 location.search() 并且它不是关于搜索文本。您误解了文档。
