Monkey 修补 CKEditor 以嵌入 YouTube 视频

发布于 2024-10-17 21:32:49 字数 892 浏览 1 评论 0原文

我正在尝试配置 CKEditor，以便它可以直接嵌入 YouTube 视频...我看到有一个建议的补丁< /a> 但我想保持原来的 CKEditor 发行版不变，所以我想知道是否可以在运行时“猴子修补”CKEditor，这样如果用户在 Flash 对话框中输入 YouTube URL，该 URL 就会转换为允许嵌入。

我已经尝试过这个：

CKEDITOR.on('dialogDefinition', function(ev){
    if (dialogName == 'flash'){
        var infotab = dialogDefinition.getContents('info');
        var f = dialogDefinition.onOk;
        dialogDefinition.onOk = function(ev) {
            var cur = this.getContentElement('info', 'src').getValue();
            var newurl = cur.replace('youtube.com/watch?v=', 'youtube.com/v/'); 
            if (cur != newurl) { 
                this.getContentElement('info', 'src').setValue(newurl);
            };
            f(ev);
       }
    }
}

但它不起作用，因为在 f 内部代码使用 this，而我的“补丁”改变了它......

I'm trying to configure CKEditor so that it could embed YouTube videos directly... I saw there's a proposed patch but I want to keep the original CKEditor distribution as it is, so I was wondering if it's possible to "monkey patch" CKEditor at runtime so that if the user types a YouTube URL inside the Flash dialog, the URL gets transformed to allow embedding.

I've tried this:

CKEDITOR.on('dialogDefinition', function(ev){
    if (dialogName == 'flash'){
        var infotab = dialogDefinition.getContents('info');
        var f = dialogDefinition.onOk;
        dialogDefinition.onOk = function(ev) {
            var cur = this.getContentElement('info', 'src').getValue();
            var newurl = cur.replace('youtube.com/watch?v=', 'youtube.com/v/'); 
            if (cur != newurl) { 
                this.getContentElement('info', 'src').setValue(newurl);
            };
            f(ev);
       }
    }
}

but it won't work, since inside f the code uses this, and my "patch" changes it...

如果将 onOK 附加到 dialogDefinition 的另一个属性，则 this 在其中将是正确的（我认为）。

CKEDITOR.on('dialogDefinition', function(ev){
    if (dialogName == 'flash'){
        var infotab = dialogDefinition.getContents('info');
        dialogDefinition.oldOnOk = dialogDefinition.onOk; //change here
        dialogDefinition.onOk = function(ev) {
            var cur = this.getContentElement('info', 'src').getValue();
            var newurl = cur.replace('youtube.com/watch?v=', 'youtube.com/v/');
            if (cur != newurl) { 
                this.getContentElement('info', 'src').setValue(newurl);
            };
           dialogDefinition.oldOnOk(ev); //and change here
       }
    }
}

或者使用Function.apply：

CKEDITOR.on('dialogDefinition', function(ev){
    if (dialogName == 'flash'){
        var infotab = dialogDefinition.getContents('info');
        var f = dialogDefinition.onOk; 
        dialogDefinition.onOk = function(ev) {
            var cur = this.getContentElement('info', 'src').getValue();
            var newurl = cur.replace('youtube.com/watch?v=', 'youtube.com/v/');
            if (cur != newurl) { 
                this.getContentElement('info', 'src').setValue(newurl);
            };                
            f.apply(this, ev);  //change here
       }
    }
}

If you attach the onOK to another property of dialogDefinition, this will be correct within it (I think).

CKEDITOR.on('dialogDefinition', function(ev){
    if (dialogName == 'flash'){
        var infotab = dialogDefinition.getContents('info');
        dialogDefinition.oldOnOk = dialogDefinition.onOk; //change here
        dialogDefinition.onOk = function(ev) {
            var cur = this.getContentElement('info', 'src').getValue();
            var newurl = cur.replace('youtube.com/watch?v=', 'youtube.com/v/');
            if (cur != newurl) { 
                this.getContentElement('info', 'src').setValue(newurl);
            };
           dialogDefinition.oldOnOk(ev); //and change here
       }
    }
}

Or use Function.apply:

CKEDITOR.on('dialogDefinition', function(ev){
    if (dialogName == 'flash'){
        var infotab = dialogDefinition.getContents('info');
        var f = dialogDefinition.onOk; 
        dialogDefinition.onOk = function(ev) {
            var cur = this.getContentElement('info', 'src').getValue();
            var newurl = cur.replace('youtube.com/watch?v=', 'youtube.com/v/');
            if (cur != newurl) { 
                this.getContentElement('info', 'src').setValue(newurl);
            };                
            f.apply(this, ev);  //change here
       }
    }
}
