XUL从当前打开的选项卡中打开带有已解析URI的新选项卡

Question

我正在使用的javascript函数似乎没有响应，或者我在某个地方有错误的语法。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中，获取URL，解析它，然后将该url传递给另一个服务器上的脚本(在新的选项卡中)

我设法让它打开了一个新的标签..但是我尝试解析URL的每一种方法都失败了。

下面是我当前的代码：

CheckWhois = {

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

var m = parser[mode].exec(str),

}
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Noob问题:)

任何帮助都将不胜感激:)

Answer 1

在不接触解析器的情况下，这里有一个问题：

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+。可能在您的控制台(CTRL+SHIFT+J)中有一个错误，在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'));

这是假设parse_url()函数传递了正确的字符串。您可以使用以下命令进行测试：

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