如何修改自動調整大小插件以便可以將選項autoresize_max_height設置爲原始高度的百分比?tinymce使用原始高度的百分比自動調整插件

E.g

var defaults = { 
    height: 500, 
    autoresize_max_height: "150%", 
} 

$(selectTinyMce).tinymce(defaults); 

$(selectTinyMceSmall).tinymce($.extend(true, {}, defaults, { 
    height: 200 
})); 

$(selectTinyMceLarge).tinymce($.extend(true, {}, defaults, { 
    height: 1000 
}));

      t.autoresize_max_height = parseInt(ed.getParam('autoresize_max_height', 0)); 

      // Add padding at the bottom for better UX 
      ed.onInit.add(function(ed){ 
       ed.dom.setStyle(ed.getBody(), 'paddingBottom', ed.getParam('autoresize_bottom_margin', 10) + 'px'); 
      });

      if (ed.getParam('autoresize_on_init', true)) {

      // Register the command so that it can be invoked by using tinyMCE.activeEditor.execCommand('mceExample'); 
      ed.addCommand('mceAutoResize', resize); 
     }, 

     /**

     * 
     * @return {Object} Name/value array containing information about the plugin. 
     */ 
     getInfo : function() { 
      return { 
       longname : 'Auto Resize', 
       author : 'Moxiecode Systems AB', 
       authorurl : 'http://tinymce.moxiecode.com', 
       infourl : 'http://wiki.moxiecode.com/index.php/TinyMCE:Plugins/autoresize', 
       version : tinymce.majorVersion + "." + tinymce.minorVersion 
      }; 
     } 
    }); 

    // Register plugin 
    tinymce.PluginManager.add('autoresize', tinymce.plugins.AutoResizePlugin); 
})(); 

注:我已經加入if (myHeight < ed.getParam("height"))以確保高度不得低於原來的高度使之充分編輯器「點擊」默認情況下它有很多的填充。

您可以使用配置heigth信息在插件來計算autoresize_max_height值:

// Define maximum height 
var percentage = parseInt(ed.getParam('autoresize_max_height', 0)); // the value here is a percentage value without the "%" 

t.autoresize_max_height = ed.getParam('height') || 500; // 500 as default if height has not been set 
// apply the percentage 
t.autoresize_max_height = parseInt(t.autoresize_max_height * (percentage/100));
