我正在使用nicEdit来拥有一个 RTF 文本区域,我需要添加一个onkeypress,onkeyuponkeydown事件。

我像这样创建我的实例:

var emailRtf = new nicEditor({  iconsPath : 'nicEdit/nicEditorIcons.gif', 
    buttonList : ['bold','italic','underline','fontSize','forecolor','ol','ul','link','unlink','removeformat'],
    maxHeight: 600}).panelInstance('REPLY_MESSAGE');

我尝试了以下方法(使用keypress,keydownkeyup):

emailRtf.addEvent("keypress", function() { alert('test') }); // Not working
emailRtf.addEvent("keypress", function(evt) { alert('test') }); // Not working

但是,以下工作:

emailRtf.addEvent("blur", function() { alert('test') }); // Alert shows when I leave focus on the textArea

如何添加key(press|up|down)到 nicEdit 编辑器?

注意:我的页面中有多个 RTF textarea 实例,我只需要将key(press|down|up)事件添加到一个。我发现了这个问题,它在所有实例上添加了事件。另外,我想保持 nicEdit.js 完整。

看看这里限制所见即所得编辑器中的字符数(NicEdit)

它应该可以在不更改 nicedit.js 的情况下工作

$("div.nicEdit-main").keyup(function () { });

看看jsfiddle http://jsfiddle.net/jGLRn/15/

在此处阅读官方文档它向您展示了如何在不使用 jQuery的情况下将(它们支持的)事件绑定到您的 nicEdit 实例:

var commentNicEditor = new nicEditor().panelInstance('comment');
commentNicEditor.addEvent("blur", function () {
    // Sent when an editor instance loses focus    
});
commentNicEditor.addEvent("focus", function () {
    // Send when an editor gains focus (IE someone clicks inside it)    
});
commentNicEditor.addEvent("key", function () {
    // When the user presses a shortcut key (Such as control-b)    
});
commentNicEditor.addEvent("add", function () {
    // Fired when a new instance is added    
});
commentNicEditor.addEvent("panel", function () {
    // Fired when the toolbar is initialized for new instances (This is the preferred event if you want to add a function when NicEdit instances are created)    
});

经过一天的研究,不修改nicEdit.js是不行的。但是,我能够进行很少的更改。它们在这里(我使用的是 0.9r24 版本):

我添加了一个名为customKeyDownFunction. 默认情况下它什么也不做。

var nicEditorConfig = bkClass.extend({
    buttons : {
        'bold' : {name : __('Click to Bold'), command : 'Bold', tags : ['B','STRONG'], css : {'font-weight' : 'bold'}, key : 'b'},
        'italic' : {name : __('Click to Italic'), command : 'Italic', tags : ['EM','I'], css : {'font-style' : 'italic'}, key : 'i'},
        'underline' : {name : __('Click to Underline'), command : 'Underline', tags : ['U'], css : {'text-decoration' : 'underline'}, key : 'u'},
        'left' : {name : __('Left Align'), command : 'justifyleft', noActive : true},
        'center' : {name : __('Center Align'), command : 'justifycenter', noActive : true},
        'right' : {name : __('Right Align'), command : 'justifyright', noActive : true},
        'justify' : {name : __('Justify Align'), command : 'justifyfull', noActive : true},
        'ol' : {name : __('Insert Ordered List'), command : 'insertorderedlist', tags : ['OL']},
        'ul' :  {name : __('Insert Unordered List'), command : 'insertunorderedlist', tags : ['UL']},
        'subscript' : {name : __('Click to Subscript'), command : 'subscript', tags : ['SUB']},
        'superscript' : {name : __('Click to Superscript'), command : 'superscript', tags : ['SUP']},
        'strikethrough' : {name : __('Click to Strike Through'), command : 'strikeThrough', css : {'text-decoration' : 'line-through'}},
        'removeformat' : {name : __('Remove Formatting'), command : 'removeformat', noActive : true},
        'indent' : {name : __('Indent Text'), command : 'indent', noActive : true},
        'outdent' : {name : __('Remove Indent'), command : 'outdent', noActive : true},
        'hr' : {name : __('Horizontal Rule'), command : 'insertHorizontalRule', noActive : true}
    },
    iconsPath : '../nicEditorIcons.gif',
    buttonList : ['save','bold','italic','underline','left','center','right','justify','ol','ul','fontSize','fontFamily','fontFormat','indent','outdent','image','upload','link','unlink','forecolor','bgcolor'],
    iconList : {"bgcolor":1,"forecolor":2,"bold":3,"center":4,"hr":5,"indent":6,"italic":7,"justify":8,"left":9,"ol":10,"outdent":11,"removeformat":12,"right":13,"save":24,"strikethrough":15,"subscript":16,"superscript":17,"ul":18,"underline":19,"image":20,"link":21,"unlink":22,"close":23,"arrow":25},
    customKeyDownFunction : function() { }  
});

我修改了 keyDown 函数。

keyDown : function(e,t) {
    this.ne.options.customKeyDownFunction();

    if(e.ctrlKey) {
        this.ne.fireEvent('key',this,e);
    }
}

当我创建我的 nicEditor 实例时,我定义customKeyDownFunction.

var emailRtf = new nicEditor({  
        iconsPath : 'nicEdit/nicEditorIcons.gif', 
        buttonList : ['bold','italic','underline','fontSize','forecolor','ol','ul','link','unlink','removeformat'],
        maxHeight: 600,
        customKeyDownFunction: function() { alert('key down!'); }
    }).panelInstance('REPLY_MESSAGE');

如果您不需要任何自定义函数,只需不要定义customKeyDownFunction.

var emailRtf = new nicEditor({  
        iconsPath : 'nicEdit/nicEditorIcons.gif', 
        buttonList : ['bold','italic','underline','fontSize','forecolor','ol','ul','link','unlink','removeformat'],
        maxHeight: 600
    }).panelInstance('REPLY_MESSAGE');

这是我能做的最好的了。如果有人有更好的方法,请告诉!

或者您可以尝试这种方式:

$('body').on("keyup", ".nicEdit-main", function(){
  //Do Something...
}
