My app injects a js to TiddlyWiki webview, which is a modified version of
scripts inside the desktop app TiddlyDesktop:
var enableSaving = function(doc) {
var messageBox = doc.createElement("div");
messageBox.id = "tiddlyfox-message-box";
doc.body.appendChild(messageBox);
messageBox.addEventListener("tiddlyfox-save-file",function(event) {
var message = event.target,
filepath = message.getAttribute("data-tiddlyfox-path"),
content = message.getAttribute("data-tiddlyfox-content");
window.client.saveWiki(filepath,content);
message.parentNode.removeChild(message);
var event = doc.createEvent("Events");
event.initEvent("tiddlyfox-have-saved-file",true,false);
event.savedFilePath = filepath;
message.dispatchEvent(event);
return false;
},false);
};
enableSaving(document);
It seems that the code provides no downloading interface. The only thing
they do is to get the content of current page.
