Ace 编辑器 - 通过 POST 在服务器上保存/发送会话 [英] Ace editor - save/send session on server via POST

问题描述

我编写在线网页编辑器，我想在服务器上保存当前视图/工作，以备将来恢复.我也想做多个标签.

I write online webpage editor and I would like save current view/work on server, for restore in future. I also want do multiple tabs.

我知道，那就是 editor.getSession() 和 editor.setSession().

I know, that is editor.getSession() and editor.setSession().

JS:

var editor = ace.edit("description");
editor.session.setMode("ace/mode/javascript");
editor.setTheme("ace/theme/tomorrow");
editor.setShowPrintMargin(false);
editor.setOptions({
    enableBasicAutocompletion: true,
    enableSnippets: true
});

现在我尝试通过 jQuery $.data() 将会话保存到元素:

Now I try save session via jQuery $.data() to element:

$('#tab1').data('sesi',editor.getSession()); //save session
editor.setSession($('#tab2').data('sesi')); //restore other session

但是这段代码不起作用.当我尝试 console.log(editor.session); 我在控制台看到很多代码.

But this code not working. When I try console.log(editor.session); I see a lot of code in console.

我尝试通过 POST 数据将 session 发送到服务器，但在网络控制台中，我只看到来自编辑器的代码，仅此而已......

I tried send session to server via POST data, but in network console I see only code from editor and nothing more...

$.ajax({
    type: "POST",
    url: "aaaaa.php",
    cache: false,
    timeout: 10000,
    data: "session="+ editor.session
});

如何将会话保存到变量或服务器?

How to save session to variable or to server?

推荐答案

要将会话保存到服务器，您需要将其转换为可以传递给 json.Stringify 的普通对象.session="+ editor.session 在你的例子中只是调用 session.toString，它与 session.getValue 相同

to save session to server you need to convert it to plain object which can be passed to json.Stringify. session="+ editor.session in your example simply calls session.toString which is same as session.getValue

var filterHistory = function(deltas){ 
    return deltas.filter(function (d) {
        return d.group != "fold";
    });
}

sessionToJSON = function(session) {
    return {
        selection: session.selection.toJSON(),
        value: session.getValue(),
        history: {
            undo: session.$undoManager.$undoStack.map(filterHistory),
            redo: session.$undoManager.$redoStack.map(filterHistory)
        },
        scrollTop: session.getScrollTop(),
        scrollLeft: session.getScrollLeft(),
        options: session.getOptions()
    }
}

sessionFromJSON = function(data) {
    var session = require("ace/ace").createEditSession(data.value);
    session.$undoManager.$doc = session; // workaround for a bug in ace
    session.setOptions(data.options);
    session.$undoManager.$undoStack = data.history.undo;
    session.$undoManager.$redoStack = data.history.redo;
    session.selection.fromJSON(data.selection);
    session.setScrollTop(data.scrollTop);
    session.setScrollLeft(data.scrollLeft);
    return session;
};

现在获取会话状态

var session = editor.session
var sessionData = sessionToJSON(session)
$.ajax({
    type: "POST",
    url: "aaaaa.php",
    cache: false,
    timeout: 10000,
    data: JSON.stringify(sessionData)
});

并从服务器恢复它

var session = sessionFromJSON(JSON.parse(ajaxResponse))
editor.setSession(session)
