Rico 模块加载模式

Rico 模块加载方式

Rico.loadModule('Accordion');

Rico中有一个管理模块依赖的对象

moduleDependencies : {
    Accordion  : ['ricoBehaviors.js','ricoEffects.js','ricoComponents.js'],
    Color      : ['ricoStyles.js'],
    Corner     : ['ricoStyles.js'],
    DragAndDrop: ['ricoStyles.js','ricoEffects.js','ricoDragDrop.js'],
    Effect     : ['ricoEffects.js'],
    Calendar   : ['ricoCalendar.js', 'ricoCalendar.css'],
    Tree       : ['ricoTree.js', 'ricoTree.css'],
    ColorPicker: ['ricoColorPicker.js', 'ricoStyles.js', 'ricoColorPicker.css'],
    CustomMenu : ['ricoMenu.js', 'ricoMenu.css'],
    SimpleGrid : ['+Effect', 'ricoGridCommon.js', 'ricoGrid.css', 'ricoSimpleGrid.js'],
    LiveGridBasic : ['ricoGridCommon.js', 'ricoGrid.css', 'ricoBehaviors.js', 'ricoLiveGrid.js'],
    LiveGrid      : ['+Effect', '+LiveGridBasic', 'ricoLiveGridControls.js'],
    LiveGridMenu  : ['+CustomMenu', 'ricoLiveGridMenu.js'],
    LiveGridAjax  : ['+LiveGrid', 'ricoLiveGridAjax.js'],
    LiveGridJSON  : ['+LiveGridAjax', 'ricoLiveGridJSON.js'],
    LiveGridForms : ['+LiveGridAjax', '+LiveGridMenu', '+Accordion', '+Corner', 'ricoLiveGridForms.js', 'ricoLiveGridForms.css'],
    SpreadSheet   : ['+SimpleGrid', 'ricoSheet.js', 'ricoSheet.css']
  }

每次loadModule模块时，通过内部的include方法加载所需的js或css文档

loadModule

loadModule : function() {
    for (var a=0, length=arguments.length; a<length; a++) {
      var name=arguments[a];
      var dep=this.moduleDependencies[name];
      if (dep) {
        for (var i=0; i<dep.length; i++) {
          if (dep[i].substring(0,1)=='+') {
            this.loadModule(dep[i].slice(1));
          } else {
            this.include(dep[i]);
          }
        }
      } else {
        this.include(name);
      }
    }
  }

include方法
 

include : function(filename) {
    if (this.loadedFiles[filename]) return;
    this.addPreloadMsg('include: '+filename);
    var ext = filename.substr(filename.lastIndexOf('.')+1);
    switch (ext.toLowerCase()) {
      case 'js':
        this.loadedFiles[filename]=filename.substring(0,4)=='rico' ? this.loadRequested : this.loadComplete;
        document.write("<script type='text/javascript' src='"+this.jsDir+filename+"'><\/script>");
        return;
      case 'css':
        var el = document.createElement('link');
        el.type = 'text/css';
        el.rel = 'stylesheet';
        el.href = this.cssDir+filename;
        this.loadedFiles[filename]=this.loadComplete;
        document.getElementsByTagName('head')[0].appendChild(el);
        return;
    }
  }
