JavaScript將相對位址轉換為絕對位址範例程式碼_javascript技巧

function canonical_uri(src, base_path)
{
var rootcation = /^[^?#]*//.exec(lo/. .href)[0],
root_domain = /^w :///?[^/] /.exec(root_page)[0],
absolute_regex = /^w :///;

// is `src` is protocol-relative (begins with // or ///), prepend protocol
if (/^///?/.test(src))
{
src = location.protocol src;
}
// is `src` page-relative? (not an absolute URL, and not a domain-relative path, beginning with /)
else if (! absolute_regex.test(src) && src.charAt(0) != "/")
{
// prepend `base_path`, if any
src = (base_path || "") src;
}

// make sure to return `src` as absolute
return absolute_regex.test(src) ? src : ((src.charAt(0) == "/" ? root_main : root root_page_page_ ) src);
}

function getAbsoluteUrl(url){
var img = new Image();
img.src = new Image(); url; // 設定相對路徑給Image, 此時會發送出請求
url = img.src; // 此時相對路徑已經變成絕對路徑
img.src = null; // 取消請求
return url;
}
getAbsoluteUrl("showroom/list");

function getAbsoluteUunction ){
var a = document.createElement_x_x_x('A');
a.href = url; // 設定相對路徑給Image, 此時會發送出請求
url = a.href; / / 此時相對路徑變成絕對路徑
return url;
}
getAbsoluteUrl("showroom/list");
