我有低于此功能才能正常工作：

I have a function below which works correctly:

function insertQuestion(form) {   
    var $tbody = $('#qandatbl > tbody'); 
    var $tr = $("<tr class='optionAndAnswer' align='center'></tr>");
    var $noofanswers = $("<td class='noofanswers'></td>");
    var $questionType = '';

    $('.numberAnswerTxt', context).each(function() {
        var $this = $(this);
        var $noofanswersText = '';

        if ($questionType == 'True or False' || $questionType == 'Yes or No') {
            $noofanswersText = $("<span class='naRow string' style='display: block;'>Only 1 Answer</span><input type='text' class='numberAnswerTxtRow answertxt' style='display: none;' onkeyup='numberKeyUp(this)' onkeypress='return isNumberKey(event)' onChange='getButtons()'>").attr('name', $this.attr('name')).attr('value', $this.val());
        }
        else {
            $noofanswersText = $("<span class='naRow string' style='display: none;'>Only 1 Answer</span><input type='text' class='numberAnswerTxtRow answertxt' style='display: block;' onkeyup='numberKeyUp(this)' onkeypress='return isNumberKey(event)' onChange='getButtons()'>").attr('name', $this.attr('name')).attr('value', $this.val());  
        }

        $noofanswers.append($noofanswersText);
    }); 

    $tr.append($noofanswers);
    $tbody.append($tr); 
}

不过，我想 $ noofanswers 将包含在它自己的表行，所以我再改 $ noofanswers 包括＆LT; TR＆GT;＆LT; / TR＆GT; 使code：

But I wanted $noofanswers to be included in it's own table row so I then change $noofanswers to include <tr></tr> so that code:

var $noofanswers = $("<td class='noofanswers'></td>");

现在变成了：

var $noofanswers = $("<tr><td class='noofanswers'></td></tr>");

但是，如果我这样做，那么 $（'。numberAnswerTxt，背景）。每个（函数（）{不正确不是那么回事。所以我的问题是，如果我添加了＆LT; TR＆GT; 标签，那什么，我需要在函数中改变让它再次合作

But if I do this then $('.numberAnswerTxt', context).each(function() { doesn't quite work correctly. So my question is that if I add the <tr> tags, then what do I need to change within the function to get it working again?

推荐答案

在 insertQuestion 功能已经包装了 D 在元素 TR ：

The insertQuestion function already wraps the td element in a tr:

var $tr = $("<tr class='optionAndAnswer' align='center'></tr>");
//...
$tr.append($noofanswers);

您可以简单地修改 TR 的 $ TR ，而不是增加 $ noofanswers ，或者你可以删除调用追加并保持 TR 在 $ noofanswers 。

You could simply modify $tr instead of adding the tr to $noofanswers, or you could remove the call to append and keep the tr in $noofanswers.

//var $tr = $("<tr class='optionAndAnswer' align='center'></tr>");
var $noofanswers = $("<tr><td class='noofanswers'></td></tr>");
//...
//$tr.append($noofanswers);
$tbody.append($noofanswers);
