XUL 使用当前打开选项卡中解析的 URI 打开新选项卡

Question

我正在使用的 javascript 函数似乎没有响应，或者我在某处的语法不正确。我使用的 Parse_URL 函数来自 http://phpjs.org/functions/parse_url:485。

我想要做的是；从当前打开的选项卡；获取 URL，解析它，然后将该 URL 传递给另一台服务器上的脚本（在新选项卡中）

我设法让它打开一个新选项卡.. 但我尝试解析 URL 的每种方法都会很短。

这是我当前的代码：

CheckWhois = {

1: function () {
//parse this URI
function parse_url (str, component) {

    };

var m = parser[mode].exec(str),
    uri = {},
    i = 14;
while (i--) {
    if (m[i]) {
      uri[key[i]] = m[i];

    return uri[component.replace('PHP_URL_', '').toLowerCase()];
}
if (mode !== 'php') {

        if ($1) {uri[name][$1] = $2;}
    });
}
delete uri.source;
return uri;
 }
var URI = currentBrowser.currentURI.spec;

//unsure if this will work
var tab = document.getElementById("content").addTab("tools.whois.com.au/whois/?domain=" . parse_url("test.com", 'host'));
document.getElementById("content").selectedTab = tab;
document.getElementById("urlbar").focus();

  },

}

我不习惯 javascript，这绝对是一个菜鸟问题:)

任何帮助将不胜感激:)

Answer 1

甚至无需触及解析器，就会出现一个问题：

var tab = document.getElementById("content").addTab("tools.whois.com.au/whois/?domain=" . parse_url("test.com", 'host'));

javascript 不使用 . 作为加法运算符，它使用 +。您的控制台 (CTRL+SHIFT+J) 中可能存在错误，当您运行脚本时会告诉您这一点。

尝试：

var tab = document.getElementById("content").addTab("tools.whois.com.au/whois/?domain=" + parse_url("test.com", 'host'));

假设 parse_url() 函数传递正确的字符串。您可以使用以下方法进行测试：

window.alert(parse_url("test.com", 'host'))
