Extjs/js两个对象的属性进行混合

/* * @param {Object} target 目标对象。 @param {Object} source 源对象。 @param {boolean} * deep 是否复制(继承)对象中的对象。 @returns {Object} 返回继承了source对象属性的新对象。 */ Mixing2Object : function ( target , source ,deep ){ target = target || {}; var sType = typeof source , i = 1 , options; if ( sType === 'undefined' || sType === 'boolean' ){ deep = sType === 'boolean' ? source : false; source = target; target = this; } if ( typeof source !== 'object' && Object.prototype.toString.call( source ) !== '[object Function]' ) source = {}; while ( i <= 2 ){ options = i === 1 ? target : source; if ( options != null ){ for( var name in options){ var src = target [name] , copy = options [name]; if ( target === copy ) continue; if ( deep && copy && typeof copy === 'object' && !copy.nodeType ) target [name] = this.extend( src || (copy.length != null ?
