我在制作小书签,它检查主体是否存在特定的文本字符串,并在找到时运行脚本。我用document.body.search();
但它只是给出了控制台错误消息使用document.body.search()的小书签
[Error] TypeError: undefined is not a function (evaluating 'document.body.search('application is temporarily over its serving quota')')
。我是否使用search()
错误?我应该使用document.body
以外的东西吗?
的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;
}
显然'document.body.search'不存在。你期望它做什么? – melpomene
我不认为'document.body'有搜索功能。要检查文本片段,您可能需要迭代所有搜索的元素,并将它们与文本字符串进行比较。 – Ryan
