还在学习并需要一些帮助。
此代码示例检查url的有效性:
function check_URL() {
var url = "http://" + localStorage['t'] + ".somewhere.com";
$.getJSON("http://query.yahooapis.com/v1/public/yql?"+
"q=select%20*%20from%20html%20where%20url%3D%22"+
encodeURIComponent(url)+
"%22&format=xml'&callback=?",
function(data){
if(data.results[0]){
console.log("yes");
}
else {
console.log("no");
alert(url + " is not a valid URL or is down.");
}
}
);
};
它完全符合我的要求(我在这里找到它!)。但是,我也需要检查其他网址。
我怎么能用.each做到这一点?我对这些东西太新了,一个例子可以帮助我学习。
此外,如果有帮助,示例中使用的“某处”域将始终相同。
更新:感谢蒂亚戈帮我指明了正确的方向。
function check_URL() {
var url = "http://" + localStorage['t'] + ".somewhere.com";
var url1 = "http://" + localStorage['t1'] + ".somewhere.com";
var url2 = "http://" + localStorage['t2'] + ".somewhere.com";
var url3 = "http://" + localStorage['t3'] + ".somewhere.com";
var urlArray = ['url', 'url1', 'url2','url3'];
$(urlArray).each(function (urlItem) {
$.getJSON("http://query.yahooapis.com/v1/public/yql?"+
"q=select%20*%20from%20html%20where%20url%3D%22"+
encodeURIComponent(urlItem)+
"%22&format=xml'&callback=?",
function(data){
if(data.results[0]){
console.log("yes");
}
else {
console.log("no");
alert(url + " is not a valid URL or is down.");
}
}
);
});
};
这似乎找到了任何未验证的网址,但警报已被破坏。
想法?
谢谢!

var urlArray = ['url', 'url1', 'url2'];
$(urlArray).each(function (urlItem) {
//do your stuff with your urlItem string
});

这是我使用的解决方案。感谢@BaylorRae'的指导!
function check_URL() {
var url = "http://" + localStorage['t'] + ".somewhere.com";
var url1 = "http://" + localStorage['t1'] + ".somewhere.com";
var url2 = "http://" + localStorage['t2'] + ".somewhere.com";
var url3 = "http://" + localStorage['t3'] + ".somewhere.com";
var urlArray = [url, url1, url2, url3],
invalidUrls = [];
$.each(urlArray, function (i, urlItem) {
$.getJSON("http://query.yahooapis.com/v1/public/yql?"+
"q=select%20*%20from%20html%20where%20url%3D%22"+
encodeURIComponent(urlItem)+
"%22&format=xml'&callback=?",
function(data){
if(data.results[0]){
console.log("yes");
}
else {
invalidUrls.push(urlItem);
}
}
);
});
return invalidUrls;
};
