你在所有的属性缺失报价，而你再使用rowQuestion ID，以科尔等它。始终将您的属性包含在引号中。

作为替代你目前的做法，check out jQuery templates，为您的代码模板是这样的（我希望你会同意，更容易维护和）：

<script id="rowTmpl" type="text/x-jquery-tmpl"> 
    {{each items}} 
    <tr class="rowQuestion"> 
    <td>${$index+1}</td> 
    <td><input type="hidden" name="question${$index}" id="question${$index}" value="${$value.ContentQuestion}">${$value.ContentQuestion}</td> 
    <td> 
     <select name="answer${$index}" id="answer${$index}"> 
     <option name="answerA" value="A">${$value.OptionAQuestion}</option> 
     <option name="answerB" value="B">${$value.OptionBQuestion}</option> 
     <option name="answerC" value="C">${$value.OptionCQuestion}</option> 
     <option name="answerD" value="D">${$value.OptionDQuestion}</option> 
     </select> 
    </td> 
    </tr 
    {{/each}}> 
    <tr> 
    <td> 
     <input type="hidden" name="countof_record" id="countof_record" value="${items.length}"> 
     <input type="submit" name="submit" value="Save your answer" id="save"> 
    </td> 
    </tr> 
</script>

要有了这个

for (i = 0; i < results.data.length; i++) { 
    row = results.data[i]; 
    var questions=row.ContentQuestion; 
    alert(questions); 
    $("#questionlist").append("<tr id=rowQuestion><td>"+(i+1)+"</td><td><input type=hidden name=question"+i+" id=question"+i+" value="+questions+" size=255>"+row.ContentQuestion+"</td><td><select name=answer"+i+" id=answer"+i+"><option name=answerA value=A selected>"+row.OptionAQuestion+"</option><option name=answerB value=B>"+row.OptionBQuestion+"</option><option name=answerC value=C>"+row.OptionCQuestion+"</option><option name=answerD value=D>"+row.OptionDQuestion+"</option></select></td></tr>"); 
} 
$("#questionlist > tbody:last").append("<tr><td><input type=hidden name=countof_record id=countof_record value="+results.data.length+"><input type=submit name=submit value=Save your answer id=save></td></tr>");

：使用它，你会替换此

$("#rowTmpl").tmpl({items: results.data}).appendTo("#questionlist");

你可以修复它的尼克..因为..我仍然得到错误 – 2010-11-11 11:06:23

@Frans - 我提供了一个更好的选择上面...你的标记是完全无效的，所以你会得到各种各样的错误。 – 2010-11-11 11:09:25
