我在这里有这段代码:
var infiltrationResult;
while(thisOption) {
var trNode = document.createElement('tr');
var tdNode = document.createElement('td');
var hrefNode = document.createElement('a');
infPlanetID = thisOption.getAttribute('value');
var myURL = "http://www.hyperiums.com/servlet/Planetinf?securitylevel=90&newinfiltr=New+infiltration&planetid=" + PlanetID + "&infplanetid=" + infPlanetID;
GM_xmlhttpRequest({
method: 'GET',
url: myURL,
headers: {
'User-agent': 'Mozilla/4.0 (compatible) Greasemonkey',
'Accept': 'application/atom+xml,application/xml,text/xml',
},
onload: function(responseDetails) {
if (responseDetails.responseText.match(/<b>Invalid order<\/td><\/tr><tr><td><BR><center><font color=#AAAA77 face=verdana,arial size=2>The target planet is blocking all infiltrations[\s\S]<BR><BR>/im)) {
// Successful match
infiltrationResult = 'Invalid Order';
} else {
// Match attempt failed
infiltrationResult = 'Infiltration Successfully Created';
}
}
});
当我添加
警报(渗透结果);
分配后,我正确地看到了字符串。
但是,在函数退出后,我尝试了相同的警报,我得到:
undefined
任何想法我做错了什么?
