我正在为Firefox创建一个简单的bootstrapped插件。我需要通过单击按钮从浏览器捕获当前URL。
我的 bootstrap.js :
const {classes: Cc, interfaces: Ci, utils: Cu} = Components;
Cu.import('resource://gre/modules/Services.jsm');
Cu.import("resource://gre/modules/NetUtil.jsm");
Cu.import("resource://gre/modules/FileUtils.jsm");
/*start - windowlistener*/
var windowListener = {
//DO NOT EDIT HERE
onOpenWindow: function (aXULWindow) {
// Wait for the window to finish loading
let aDOMWindow =aXULWindow.QueryInterface(Ci.nsIInterfaceRequestor)
.getInterface(Ci.nsIDOMWindowInternal||Ci.nsIDOMWindow);
aDOMWindow.addEventListener("load", function () {
aDOMWindow.removeEventListener("load", arguments.callee, false);
windowListener.loadIntoWindow(aDOMWindow, aXULWindow);
}, false);

我尝试了Get current page URL from a firefox sidebar extension的所有建议但没有任何效果。
答案 0 :(得分:1)
但是,你已经设置了这个事实:
var propsToSet = {
id: 'demo-sidebar-with-html_browser',
type: 'content', //<---------------------------This
<browser>
type
to content
,我假设以下两件事之一:
<browser>
到src
属性的代码中获取有效标签的URI。
<browser>
内的URI表单代码的访问权限,并且不知道将<browser>
type
to content
设置为代码的限制加载到<browser>
。
<browser>
中的代码访问currant选项卡的URL。您应该考虑重构代码,以便<browser>
中的内容不需要访问chrome权限。换句话说,如果可能的话,您应该编写代码,这样您就不需要直接从您插入的<browser>
中运行的代码访问URL或其他信息。但是,这样做可能会变得更加复杂。 在您要添加的<browser>
中获取Chrome权限:
设置<browser>
type
to content
适用于:
内容浏览器。浏览器中加载的内容不允许访问其上方的镶边。
将<browser>
type
设置为chrome
适用于:
(默认行为):一种浏览器,用于使用chrome:// URI加载特权内容。 不要使用来自网络的内容,因为这可能会导致严重的安全问题!
要将<browser>
type
设置为chrome
,您可以这样做:
var propsToSet = {
id: 'demo-sidebar-with-html_browser',
type: 'chrome', //<---------------------------This
Noitidart提供的代码接近您的需求。但是,它需要稍微修改,如gBrowser.currentURI
is a nsIURI, not a string)。因此,您需要使用gBrowser.currentURI.spec
。您可以通过将makeHTML()
更改为
function makeHTML(value, key){
var arrValues = value.split(",");
var htmlContent = '<html><head></head>'
+ '<body style="background-color: white;">'
+ ' <div name="content" class="content">'
+ ' <p> Name :' + arrValues[0] + '</p>';
htmlContent += '<p> Price :' + arrValues[2] + '</p>';
htmlContent += '<p> Color :' + arrValues[3] + '</p>';
htmlContent += '<p> UID :' + arrValues[1] + '</p>';
htmlContent +=
' <p><input type="radio" name="valid" value="yes" />Yes '
+ ' <input type="radio" name="valid" value="no" /> No</p>'
+ ' <p><input type="text" placeholder="Reason" name="checkreason" /></p>'
+ ' <p><input type="text" placeholder="Feedback" name="feedback" /></p>'
+ ' </div>'
+ ' <div>'
+ ' <button name="load" type="button" id="loadit" onclick="loadHtml()" '
+ ' loadurl="' + arrValues[4] + '">Load</button>'
+ ' <button name="save" type="button">Save </button>'
+ ' <button name="next" type="button" key="' + key + '">Next </button>'
+ ' </div>'
+ ' <script>'
+ ' function loadHtml() {'
+ ' const Cu = Components.utils;'
+ ' Cu.import("resource://gre/modules/Services.jsm");'
+ ' var win = Services.wm.getMostRecentWindow("navigator:browser");'
+ ' if (win) {'
+ ' var url = win.gBrowser.currentURI.spec;'
+ ' alert("URL=" + url);'
+ ' }'
+ ' }'
+ ' </script>'
+ '</body></html>';
return htmlContent;
}
安全问题:
您可能遇到了一些非常重要的安全问题。仅仅因为您想要当前页面的URL意味着您可能正在快速接近这些是真正的问题。这将取决于您将要做什么完全。鉴于您没有提供这些信息,我不会深入探讨问题所在。但是,您应该阅读&#34; Firefox Security Basics for Developers&#34;和&#34; Security best practices in extensions&#34;
有关侧边栏的其他信息:
您应该认真考虑创建一个基于Add-on SDK的加载项,而不是一个自举加载项,并使用ui/sidebar API。
如果您有兴趣,我创建了一些代码,可用于创建&#34;侧边栏&#34;它位于活动选项卡的顶部,左侧,右侧或底部,或位于单独的窗口中(类似于devtools面板将执行的操作)。创建的侧边栏与当前活动的选项卡相关联,而不是所有选项卡(我想我应该让它成为一个选项,让它与所有选项卡相关联,或者只是当前选项卡)在我的回答中:&#34; {{3 }}&#34;和&#34; How to create a bottom-docked panel with XUL in Firefox?&#34;
