我正在尝试使用Javascript手动清理Telerik RadEditor的HTML,但我似乎无法找到存储值的正确位置,以便在回发时保存它。

这是我的JS:

$(function () {    
    jQuery.fixHash = function ($html) {      

        // modify $html

        return $html;
    };

    $("#adminEditingArea input[id$='SaveButton']").unbind("click").click(function () {
        $("iframe[id$='_contentIframe']").trigger("save");

        // call .net postback

        return false;
    });

});

var editorSaveEventInit = false;
function InitSaveEvent() {
    if (!editorSaveEventInit) {
        var $EditFrames = $("iframe[id$='_contentIframe']");
        if ($EditFrames && $EditFrames.length > 0) {
            $EditFrames.bind("save", function (e) {
                var $thisFrame = $(this);
                var thisFrameContents = $thisFrame.contents();
                if (thisFrameContents) {
                    var telerikContentIFrame = thisFrameContents.get(0);
                    var $body = $("body", telerikContentIFrame);
                    var html = $.fixHash($body).html();
                    $body.html(html);

                    // also tried storing the modified HTML in the textarea, but it doesn't seem to save:
                    //$thisFrame.prev("textarea").html(encodeURIComponent("<body>" + html + "</body>"));
                }
            });
            editorSaveEventInit = true;
        }
    }
};

$(window).load(function () {
    InitSaveEvent();
});

有没有办法用JavaScript访问Telerik RadEditor对象(使用OnClientCommandExecuted()?),以便我可以访问.get_html().set_html(value)函数?如果没有,在发回之前我需要设置什么值?

为什么不使用custom content filters

啊,刚刚发现了Telerik的内置$find()功能:http://www.telerik.com/help/aspnet-ajax/editor_getingreferencetoradeditor.html

编辑:这是我为InitSaveEvent()函数提出的解决方案:

var editorSaveEventInit = false;
function InitSaveEvent() {
    if (!editorSaveEventInit) {
        var $EditFrames = $("iframe[id$='_contentIframe']");
        if ($EditFrames && $EditFrames.length > 0) {
            $EditFrames.bind("save", function (e) {
                var $thisFrame = $(this);
                var thisFrameContents = $thisFrame.contents();
                if (thisFrameContents) {
                    var telerikContentIFrame = thisFrameContents.get(0);
                    var $body = $("body", telerikContentIFrame);
                    var html = $.fixHash($body).html();
                    // SOLUTION!
                    var $radeditor = $thisFrame.parents("div.RadEditor.Telerik:eq(0)");
                    var editor = $find($radeditor.attr("id"));
                    editor.set_html(html);
                    // ☺
                }
            });
            editorSaveEventInit = true;
        }
    }
};
