javascript - paste_preprocess tinymce 问题

Question

我想在 tinymce 编辑器中粘贴时去除所有的 html 标签。以下是不起作用的代码...以下是 tinymce 设置...paste_preprocess 回调未触发...我是否缺少某些选项..？

tinyMCESettings = [ {
        mode : "none,textareas",
        height:heightEditor,
        width:'100%',
        plugins: "paste",
        theme : "advanced", //skin : "wp_theme",
        theme_advanced_buttons1 : "bold,italic,underline,strikethrough,|,justifyleft,justifycenter",
        relative_urls : "true",
        paste_use_dialog : false,
        paste_auto_cleanup_on_paste : false,
        content_css: styleSheetToLoadForTinyMCE + "?" + new Date().getTime(),
        force_p_newlines: false,
        setup: function (ed) {
            ed.onInit.add(
                function (ed, evt) {
                    //resizeFrame1();
                    var a = tinyMCE.get(ed.id).getContent();
                    if(a.indexOf("hcRestrictedMode", 0) > 0){
                        ed.getDoc().designMode = "off";
                        setTimeout(function(){
                            tinyMCE.activeEditor.dom.setAttrib(tinyMCE.activeEditor.dom.select(".hcEditable"), 'contenteditable', 'true');
                        }, 1000);
                    }
                });
        },
        paste_preprocess : function(pl, o) {
            // Content string containing the HTML from the clipboard
            alert(o.content);
            o.content = o.content.replace(/<.+?>/,"");
        },
        paste_postprocess : function(pl, o) {
           // Content DOM node containing the DOM structure of the clipboard
           alert(o.content)
           o.content = o.content.replace(/<.+?>/,"");
       }
    }];

帮帮我... 提前谢谢...

配置代码如下:

paste_preprocess : function(pl, o) {
  alert('pasteprocess startet');
  o.content = strip_tags(o.content,'');
  //o.content = strip_tags(o.content,'<b><u><i><p><br><img>'); // use this i.e. to keep some tags
  alert('pasteprocess ended - function strip_tags found and used');
},

这里是使用的函数(取自 here )

function strip_tags (str, allowed_tags) {

    var key = '', allowed = false;
    var matches = [];    var allowed_array = [];
    var allowed_tag = '';
    var i = 0;
    var k = '';
    var html = ''; 
    var replacer = function (search, replace, str) {
        return str.split(search).join(replace);
    };
     // Build allowes tags associative array
    if (allowed_tags) {
        allowed_array = allowed_tags.match(/([a-zA-Z0-9]+)/gi);
    }
     str += '';

    // Match tags
    matches = str.match(/(<\/?[\S][^>]*>)/gi);
     // Go through all HTML tags
    for (key in matches) {
        if (isNaN(key)) {
            // IE7 Hack
            continue;        }

        // Save HTML tag
        html = matches[key].toString();
         // Is tag not in allowed list? Remove from str!
        allowed = false;

        // Go through all allowed tags
        for (k in allowed_array) {            // Init
            allowed_tag = allowed_array[k];
            i = -1;

            if (i != 0) { i = html.toLowerCase().indexOf('<'+allowed_tag+'>');}            if (i != 0) { i = html.toLowerCase().indexOf('<'+allowed_tag+' ');}
            if (i != 0) { i = html.toLowerCase().indexOf('</'+allowed_tag)   ;}

            // Determine

编辑: 将 paste_auto_cleanup_on_paste 设置为 true，它将起作用(检查我系统中的配置)
