js：

 函数get_past_issues（year，month）{
 $ .ajax（{url：'./demo/Headline/PublicationList.xml'，
 async：false ，
 success：function（xml）{
 //$(\"#dialog\").append(\"<div class ='issues'>）; 
 $（xml） .find（Publications）。find（$（PubYear [Year ='+ year +'））。each（function（）{
 // alert（$（this）.attr（ 'Year'））; 
 $（xml）.find（Publications）。find（$（PubMonth [Month ='+ month +'））。find（Publication）。 （函数（）{
 alert（$（this）.attr（'ThumbnailPath'））; 
}）; 
}）; 
 // $（＃dialog ）.append（< / div>）; 
} 
}）; 
  

例如，我提供的函数年份是2012年，月份是12，但是， PubYear [Year ='+ year +']）似乎不适用于查找功能？如何解决这个问题？谢谢

解决方案

使用fliter find（PubYear [Year ='+ year +'] ）

 函数get_past_issues（年，月）{
 $ .ajax（{url ：'./demo/Headline/PublicationList.xml'，
 async：false，
 success：function（xml）{
 //$(\"#dialog\").append(\"< ; div class ='issues'>）; 
 $（xml）.find（Publications）。find（PubYear [Year ='+ year +']）。each（function ）{
 // alert（$（this）.attr（'Year'））; 
 $（xml）.find（Publications）。find（PubMonth [Month ='+ month （）（）{
 alert（$（this）.attr（'ThumbnailPath'））; 
}）; 
 }）; 
 //$(\"#dialog\").append(\"</div>）; 
} 
}）; 
} 
  

XML:

<?xml version="1.0" encoding="utf-8"?>
<Publications LatestPubDate="2012-12-20" Version="0">
<PubYear Year="2012">
<PubMonth Month="12">
<Publication Name="Headline" PubDay="15" ThumbnailWidth="300" ThumbnailHeight="400" ThumbnailPath="FlippingBook/Dev/Frontend/OutPutFolder/Headline/2012/12/15/0/0/A/Content/1/Pg001.jpg" Version="0" Visible="true"/>
<Publication Name="Headline" PubDay="16" ThumbnailWidth="300" ThumbnailHeight="400" ThumbnailPath="FlippingBook/Dev/Frontend/OutPutFolder/Headline/2012/12/16/0/0/A/Content/1/Pg001.jpg" Version="0" Visible="true"/>

<Publication Name="Headline" PubDay="18" ThumbnailWidth="300" ThumbnailHeight="400" ThumbnailPath="FlippingBook/Dev/Frontend/OutPutFolder/Headline/2012/12/18/0/0/A/Content/1/Pg001.jpg" Version="0" Visible="true"/>
<Publication Name="Headline" PubDay="19" ThumbnailWidth="300" ThumbnailHeight="400" ThumbnailPath="FlippingBook/Dev/Frontend/OutPutFolder/Headline/2012/12/19/0/0/A/Content/1/Pg001.jpg" Version="0" Visible="true"/>
<Publication Name="Headline" PubDay="20" ThumbnailWidth="300" ThumbnailHeight="400" ThumbnailPath="FlippingBook/Dev/Frontend/OutPutFolder/Headline/2012/12/20/0/0/A/Content/1/Pg001.jpg" Version="0" Visible="true"/>
</PubMonth>
</PubYear>
</Publications>

js:

function get_past_issues(year,month) {  
    $.ajax({ url: './demo/Headline/PublicationList.xml', 
         async: false,
         success: function(xml) {
            //$("#dialog").append("<div class = 'issues'>");    
            $(xml).find("Publications").find($("PubYear[Year='" + year + "']")).each(function() {
                //alert ($(this).attr ('Year'));
                    $(xml).find("Publications").find($("PubMonth[Month='" + month + "']")).find("Publication").each(function() {
                        alert ($(this).attr ('ThumbnailPath'));
                    });
            });
            //$("#dialog").append("</div>");    
        }
    });

For instance I have provided the function year is 2012 and month is 12, however, the fliter $("PubYear[Year='" + year + "']") seems do not work with the find function? How to fix the problem ? thanks

解决方案

Use fliter find("PubYear[Year='" + year + "']")

function get_past_issues(year,month) {  
    $.ajax({ url: './demo/Headline/PublicationList.xml', 
         async: false,
         success: function(xml) {
            //$("#dialog").append("<div class = 'issues'>");    
            $(xml).find("Publications").find("PubYear[Year='" + year + "']").each(function() {
                //alert ($(this).attr ('Year'));
                    $(xml).find("Publications").find("PubMonth[Month='" + month + "']").find("Publication").each(function() {
                        alert ($(this).attr ('ThumbnailPath'));
                    });
            });
            //$("#dialog").append("</div>");    
        }
    });
}
