     $.ajax({

  success: function(data){
   var template = '    <div class="candidate" id="candidate-$1">\r\n\
     <div class="header">\r\n\

    temp = temp.replace(/\$10/g, $(this).children('profile').first().html());
    result += temp;
   });
   result = $(result);
   $('#candidates').prepend(result);
  },
  url: 'data/candidates.xml'
 });

我无法为我的生活诊断出这个问题。我有一个非常类似的方法来从questions.xml中获取问题，该方法工作正常，但是这个方法在jquery.min.js文件中生成错误。

请帮忙吗？

Answer 1

可能是因为你在$ 9线上拼写了“repalce”（而不是“replace”）？ ; - ）

我可以说服你使用Douglas Crockford's version of supplant吗？实现你正在使用它做的事情要容易得多。事实上，我会将您的代码转换为使用它：

$.ajax({
    error: function() {
        alert('Error retrieving candidates from database.');
    },
    success: function(data) {
        var template = '<div class="candidate" id="candidate-{id1}">\r\n\
 <div class="header">\r\n\
  <div class="picture"><a href="{id2}" class="target[\'_blank\']"><img src="pictures/{id1}.jpg" alt="{id4}" /></a></div>\r\n\
  <h2><a href="{id2}" class="target[\'_blank\']">{id4}</a></h2>\r\n\
  <h3>{id5}</h3>\r\n\
  <div class="stats">\r\n\
   <span class="alike" title="You have {id6}% in common with John Galt."><span class="number">{id6}</span>%</span>\r\n\
   <span class="similarity-graph" title="{id7}% of survey takers have less in common with {id3} than you do; {id8}% of survey takers have more in common with {id3} than you do.">{id7},{id8}</span>\r\n\
   <span class="certainty-graph" title="PrezMatch.com is {id9}% certain that John Galt is your best match.">{id9}</span>\r\n\
  </div>\r\n\
 </div>\r\n\
 <div class="tabs">\r\n\
  <span class="active profile-tab"><a href="javascript:;">Profile</a></span>\r\n\
  <span class="keypoints-tab"><a href="javascript:;">Key points</a></span>\r\n\
 </div>\r\n\
 <div class="active content profile-content">\r\n\
  {id10}\r\n\
 </div>\r\n\
 <div class="content keypoints-content"></div>\r\n\
</div>\r\n';
        var result = '\r\n';
        $(data).children().first().children().each(function(){
            var t = $(this), temp = template.supplant({
                id1: t.attr('id'),
                id2: t.children('link').first().html(),
                id3: t.attr('gender').toLowerCase() == 'm' ? 'him' : 'her'),
                id4: t.children('name').first().html(),
                id5: t.children('subtitle').first().html(),
                id6: '<span class="percent-in-common"></span>',
                id7: '<span class="less-in-common"></span>',
                id8: '<span class="more-in-common"></span>',
                id9: '<span class="percent-certain"></span>',
                id10: t.children('profile').first().html()
            });
            result += temp;
        });
        $('#candidates').prepend($(result));
    },
    url: 'data/candidates.xml'
});

我认为这看起来更清洁了。如果你想坚持使用基于jQuery的解决方案，你也可以看一下jQuery templating。

如果您使用我发布的链接中的版本，您将很高兴知道支持较新版ECMAScript的浏览器将使用其内置版本覆盖它，希望提高性能。

另外作为一般建议，我会在ajax调用之外移动您的模板声明，以便在success的每次调用时都不会重新创建它。
