jqueryの - 変数

Question

var attr = myopts.addAttributeFromChemSelect; 
alert(ob.attr(attr)); 

を経由して選択attrが未定義

var attr = myopts.addAttributeFromChemSelect; 
alert(attr); 

である '先端-refの'

var attr = myopts.addAttributeFromChemSelect; 
alert(ob.attr('tip-ref'); 

である理由最初の 'tip_0'

は、誰も私に説明できています仕事はありません。コンソルログから

よろしく

コードのプラグインである：

chemSelectboxRevert: function (opts, callbackFnk) { 

      var myopts = $.extend({ keepSelected: true, addAttributeFromChemSelect : '' }, opts); 

      var count = this.length; 

      return this.each(function (i) { 

       var ob = $(this); 

       var attr = myopts.addAttributeFromChemSelect; 

       console.log(getAttributes(ob)); console.log(attr); console.log(ob.attr(attr)); console.log(ob.attr('tip-ref')); 

       var extraAttr = ''; 

       if (myopts.addAttributeFromChemSelect != '') { 

        var attr_extra = ob.attr(myopts.addAttributeFromChemSelect); 

        extraAttr = myopts.addAttributeFromChemSelect + '="' + attr_extra + '"'; 

       } 
     .... 
     ...

ダーリンディミトロフ、私のテストと同じ働いた。 addAttributeFromChemSelectとは何ですか？
