我正在尝试创建一个引导的 firefox 扩展来获取当前的标签 url 和标题。问题是我想检查标签 url 的 url 中何时包含“about:”一词。我建议的解决方案是使用浏览器本机 string.substr() javascript 函数检查 require("sdk/tabs").activeTab.url"。是否可以在小部件或 ToolbarButton onClick 方法上使用浏览器本机 javasript 函数?
exports.main = function(options) {
var base64 = require("sdk/base64");
var panel = require("sdk/panel").Panel({
width: 700,
height: 470,
onHide: function ()
{
panel.contentURL = "about:blank";
}
});
var tbb = require("toolbarbutton").ToolbarButton({
id: "extension-tbb-id",
label: "IFShare+",
image: "https://www.fasdfasd.es/factory/templates/templateforidkreader/favicon.ico",
panel: panel,
onClick: function()
{
windowPanel = require("sdk/tabs").activeTab;
title = windowPanel.title;
url = windowPanel.url;
// Is any posibility to do something like that ????
contentScript: "if("+url+".substring(0,5)=='about:'){"
{
url='';
title='';
}
contentScript: "}"
this.panel.contentURL = "https://www.fasdfasdf.es/factory/index2.php?option=com_idkreader&view=shareplus&task=window&Itemid=0&url="+base64.encode(url, "utf-8")+'&title='+base64.encode(title, "utf-8")+'&ref=ext';
},
});
// move the toolbar button to the navigation bar
if ("install" == options.loadReason) {
tbb.moveTo({toolbarID: "nav-bar"});
}
}
