下午，

对于显示的每个问题，我想将此代码中的数字增加1。

 new_question = "<div id='"" + res.qId + "'">" +
                            "<h1>Question 1</h1>" +
                            "<p><i>" + res.question + "</i></p>" +
                            "<div class='"answerswer-grid'">" +
                            "<div id='"a1'" class='"answerswer'">" +
                            "<p>" + res.answer1 + "</p>" +
                            "<p>" + res.answer2 + "</p>" +
                            "<p>" + res.answer3 + "</p>" +
                            "</div>" +
                            "</div>";

有了这个，它会显示，问题1，问题2，等等…

请问我该如何在jQuery中进行此操作？

更新维克多提供了我需要的东西，感谢大家的帮助。更新了以下代码。

 var questionNumber = 1;
    $.each(result, function (index, res) {
        new_question = "<div id='"" + res.qId + "'">" +
                        "<h1>Question " + (questionNumber++) + "</h1>" +
                        "<p><i>" + res.question + "</i></p>" +
                        "<div class='"answerswer-grid'">" +
                        "<div id='"a1'" class='"answerswer'">" +
                        "<p>" + res.answer1 + "</p>" +
                        "<p>" + res.answer2 + "</p>" +
                        "<p>" + res.answer3 + "</p>" +
                        "</div>" +
                        "</div>";
        $('#pinfos').append(new_question);

在循环外声明一个变量，并在循环内递增，然后在标记中使用它。

var questionNumber=0;
$.each(someJsonData, function (index, res) {
{
 questionNumber++;
 new_question = "<div id='"" + res.qId + "'">" +
                            "<h1>Question "+questionNumber+"</h1>" +
                            "<p><i>" + res.question + "</i></p>" +
                            "<div class='"answerswer-grid'">" +
                            "<div id='"a1'" class='"answerswer'">" +
                            "<p>" + res.answer1 + "</p>" +
                            "<p>" + res.answer2 + "</p>" +
                            "<p>" + res.answer3 + "</p>" +
                            "</div>" +
                            "</div>";
}

声明一个名为questionNumber的var，并在每次调用时递增

var questionNumber = 1;
        $.each(result, function (index, res) {
            new_question = "<div id='"" + res.qId + "'">" +
                            "<h1>Question " + (questionNumber++) + "</h1>" +
                            "<p><i>" + res.question + "</i></p>" +
                            "<div class='"answerswer-grid'">" +
                            "<div id='"a1'" class='"answerswer'">" +
                            "<p>" + res.answer1 + "</p>" +
                            "<p>" + res.answer2 + "</p>" +
                            "<p>" + res.answer3 + "</p>" +
                            "</div>" +
                            "</div>";
            $('#pinfos').append(new_question);
