fontchoice.js

ajax框架原吗,dojo目前很流行的,希望大家多多学习啊

if(!dojo._hasResource["dijit._editor.plugins.FontChoice"]){ //_hasResource checks added by build. Do not use _hasResource directly in your code.
dojo._hasResource["dijit._editor.plugins.FontChoice"] = true;
dojo.provide("dijit._editor.plugins.FontChoice");

dojo.require("dijit._editor._Plugin");
dojo.require("dijit.form.FilteringSelect");
dojo.require("dojo.data.ItemFileReadStore");
dojo.require("dojo.i18n");

dojo.requireLocalization("dijit._editor", "FontChoice", null, "ROOT");

dojo.declare("dijit._editor.plugins.FontChoice",
	dijit._editor._Plugin,
	{
		_uniqueId: 0,

		buttonClass: dijit.form.FilteringSelect,

		_initButton: function(){
			this.inherited("_initButton", arguments);

			//TODO: do we need nls for font names?  provide css font lists? or otherwise make this more configurable?
			var names = {

			var items = dojo.map(names, function(x){ return { name: strings[x], value: x }; });
			items.push({name:"", value:""}); // FilteringSelect doesn't like unmatched blank strings
			this.button.store = new dojo.data.ItemFileReadStore(
