防止xulrunner中的浏览器位置更改
||
我一直在使用https://developer.mozilla.org/en/XUL_School/Intercepting_Page_Loads进行阅读和研究，但是似乎可以满足我的需要。
我正在使用Chromeless，试图防止主xulbrowser元素被导航离开，例如，链接不起作用，ѭ0也不应该。
我假设我可以通过
browser.webProgress.addProgressListener
onProgressChange
browser
browser.webProgress.addProgressListener({
onLocationChange: function(){},
onStatusChange: function(){},
onStateChange: function(){},
onSecurityChange: function(){},
onProgressChange: function(){
aRequest.QueryInterface(Components.interfaces.nsIHttpChannel)
if( /* need to check if the object triggering the event is the xulbrowser */ ){
aRequest.cancel(Components.results.NS_BINDING_ABORTED);
}
},
QueryInterface: xpcom.utils.generateQI([Ci.nsIWebProgressListener, Ci.nsISupportsWeakReference])
}, wo._browser.webProgress.NOTIFY_ALL);
nsIContentPolicy.shouldLoad()
没有找到相关结果

位不可用。const {Cc, Ci, Cu, Cm, Cr} = require(\"chrome\"); const xpcom = require(\"xpcom\"); /*********************************************************** class definition ***********************************************************/ var description = \"Chromeless Policy XPCOM Component\"; /* UID generated by http://www.famkruithof.net/uuid/uuidgen */ var classID = Components.ID(\"{2e946f14-72d5-42f3-95b7-4907c676cf2b}\"); // I just made this up. Don\'t know if I\'m supposed to do that. var contractID = \"@mozilla.org/chromeless-policy;1\"; //class constructor function ChromelessPolicy() { //this.wrappedJSObject = this; } // class definition var ChromelessPolicy = { // properties required for XPCOM registration: classDescription: description, classID: classID, contractID: contractID, xpcom_categories: [\"content-policy\"], // QueryInterface implementation QueryInterface: xpcom.utils.generateQI([Ci.nsIContentPolicy, Ci.nsIFactory, Ci.nsISupportsWeakReference]), // ...component implementation... shouldLoad : function(aContentType, aContentLocation, aRequestOrigin, aContext, aMimeTypeGuess, aExtra) { let result = Ci.nsIContentPolicy.ACCEPT; // only filter DOCUMENTs (not SUB_DOCUMENTs, like iframes) if( aContentType === Ci.nsIContentPolicy[\"TYPE_DOCUMENT\"] // block http(s) protocols... && /^http(s):/.test(aContentLocation.spec) ){ // make sure we deny the request now result = Ci.nsIContentPolicy.REJECT_REQUEST; } // continue loading... return result; }, createInstance: function(outer, iid) { if (outer) throw Cr.NS_ERROR_NO_AGGREGATION; return this.QueryInterface(iid); } }; let registrar = Cm.QueryInterface(Ci.nsIComponentRegistrar); try { Cm.nsIComponentRegistrar.registerFactory(classID, description, contractID, ChromelessPolicy); } catch (e) { // Don\'t stop on errors - the factory might already be registered Cu.reportError(e); } const categoryManager = Cc[\"@mozilla.org/categorymanager;1\"].getService(Ci.nsICategoryManager); for each (let category in ChromelessPolicy.xpcom_categories) { categoryManager.addCategoryEntry(category, ChromelessPolicy.classDescription, ChromelessPolicy.contractID, false, true); }
