自定义标记选择.attr返回undefined

Question

我已经创建了一个自定义标记，现在我正在尝试获取自定义属性的值，我尝试了很多方法，出于某种原因警报返回undefind ...谢谢你们。

<goladmin:select cssClass="shortSelect" 
      path="textType" 
      items="${textTypeList}" 
      itemValue="id" 
      itemLabel="description" 
      widgetType="widget"        
      onchange="true"             
      multiple="false" /> 

的JavaScript

<script language="javascript" type="text/javascript"> 
$(document).ready(function() { 

    //call to get the widget type 
    getWidgetType();  

    //On select dropdown change 
    $('#textType').change(function(){ 

     var wt = $('#textType').val(); 
     alert("widgetType=" + wt); 


     //call to get the widget type 
     //getWidgetType(); 
    }); 
}); 


function getWidgetType(){ 

    var value = $('#textType').val(); 
    //set hidden textTypeWidget to the selected widget 
    $('#textTypeWidget').val(value); 

    //get the widget type value from the hidden field 
    var widgetType = $('#textTypeWidget').val(); 

    // show and hide the editor based on the widget type 
    if(widgetType == "CKEDITOR") {    
     $('#ckEditorEditor').show(); 
     $('#textAreaEditor').hide(); 

    }else{ 
     $('#ckEditorEditor').hide(); 
     $('#textAreaEditor').show(); 
    } 

}

Answer 1

尝试使用：的

var wt = $('.shortSelect').attr('widgetType'); 

代替：

var wt = $('#textType').attr('widgetType'); 

Answer 2

的 '＃' 是id选择，你需要设置ID在你的元素：

<goladmin:select 
     id="textType" 
     cssClass="shortSelect" 
     path="textType" 
     items="${textTypeList}" 
     itemValue="id" 
     itemLabel="description" 
     widgetType="widget"        
     onchange="true"             
     multiple="false" /> 

var wt = $('#textType').attr('widgetType'); 
alert("widgetType=" + wt);
