javascript - 使用 jQuery 读取 XML

Question

Here's the XML:

  <employees>
  <employee ID="ABC00" lastName="Smith" firstName="Bill">
    <licenses>
      <license State="KS" liccat="Land0003" type="Landscape Architect"                 includeInProposal="Y" expiration="12/31/2016"/>
      <license State="MO" liccat="Land0003" type="Landscape Architect" includeInProposal="Y" expiration="12/31/2015"/>
      <license State="NE" liccat="Land0003" type="Landscape Architect" includeInProposal="N" expiration=""/>
    </licenses>
  </employee>
  <employee ID="ADM01" lastName="Smith" firstName="Sam">
    <licenses>
      <license> State="MO" liccat="Prof0008" type="Professional Engineer" includeInProposal="Y" expiration="12/31/2016"/>
      <license State="KS" liccat="Prof0008" type="Professional Engineer" includeInProposal="Y" expiration="04/30/2017"/>
      <license State="OK" liccat="Prof0008" type="Professional Engineer" includeInProposal="Y" expiration="08/31/2016"/>
    </licenses>
  </employee>
</employees>

Here's the code: 

$.ajax({
        type: "GET",
       url: "NLicense.xml",
       dataType: "xml",
       success: function(xml) {
            alert('Read the file');

            $(xml).find('employees').each(function(){
            var emp =  $(this).attr("lastName"); /* read the root */
            var images = $('licenses license',this).map(function() {
                  return 'hello' +  $(this).children('State').text() + " " ;
            }).get().join('');
            console.log(images);


Here's the problem:

我正在尝试提取 XML 文件中的许可证信息，但是如果您查看单词“hello”，这就是返回的全部内容。例如，在第一个 XML 条目中，我得到“hello hello hello”。

谢谢

Answer 1

我还没有测试过，但看起来你需要更改这一行:

return 'hello' +  $(this).children('State').text() + " " ;

到此

return 'hello' +  $(this).attr('State') + " " ;
