由 守給你的承諾、 提交于 2020-01-06 02:49:12
问题 I have an application which at one point wants to launch a particular URL in the default browser. This is pretty simple and can be achieved using ShellExecute on Windows. However the catch is that the server expects some additional custom header information (for authentication/identification purposes) to be sent along with the GET request. Is there any way by which this (additional header) information could be passed to the browser while launching it? Note:- I want to launch the default

问题 I have to use a plugin which bundles js files inside html files (gadgets). For one use case I need to drop and re-instantiate a gadget to run updated code. So say I have foo.html : <html> <head> <script src="foo.js"></script> </head> <body>...</body> </html> and foo.js which is the file being injected into my actual document's head: alert("hello"); Problem is I can only cachebust the html file dynamically and declare my gadget as foo.html?x=123 , but the JS file I'm after will still be foo.js

From everything I see over the internet , JavaScript is not allowed to write anything to the hard drive . Is that so ? no workarounds ? 回答1: As said in the comments, what you sound to

Create big downloable file from string variable in HTML/Javascript

由 久未见 提交于 2020-01-06 01:16:36
问题 I created a js script where I can download a file from a string variable: window.alert("a"); document.getElementById("export-graphml").innerHTML += "<a id=\"dl\" download=\"graph.graphml\">Download</a>" window.alert("b"); var vdl = document.getElementById("dl"); window.alert(data.length); vdl.href = "data:text/plain," + encodeURIComponent(data); It works very good until my string var (data) isn't too big. When my data is too big the last line of the code makes Chrome and Firefox crash and IE

Browser plugin which can register its own protocol

问题 I need to implement a browser plugin which can register its own protocol (like someprotocol://someurl) and be able to handle calls to this protocol (like user clicking on 'someprotocol' link calls function inside my plugin). As far as I understand, Skype does something similar, except I need to handle links within page context and not in a separate app. Any advice on how this can be done? Can this be done without installing my own plugin, with the help of flash/java? 回答1: Things are going to
