Question

我正在尝试生成要通过jQuery提交给ajax调用的数组。这是我的HTML和JavaScript：

//Following is the JavaScript I use to generate the variables from checked checkboxes

jQuery(document).on("click", ".refno", function() {
  var ref = jQuery(this).data("ref");
  var refindex = jQuery(this).data("refindex");

  var i = 0;
  var tutelists = [];
  var tutearray = {};
  jQuery('.datarefindex_' + refindex).each(function() {
var subjid = jQuery(this).data("subjid");
i++;

tutearray["id"] = subjid;
tutearray["issuedtutes"] = jQuery("input[name=tuteset_" + refindex + "_" + subjid + "]:checked").map(function() {
  return this.value;
}).get();

  });
  tutelists.push(tutearray);
  var tutelists = JSON.stringify(tutelists);

  jQuery("#responsecontainer").html(tutelists);

});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
<a href="javascript:void(0)" class="refno" data-refindex="1" data-ref="1105898">1105898</a>

      </li>
    </ul>
  </li>
</ul>
<div id="responsecontainer"></div

我收到的结果如下（我已经检查了每个列表中的前3个框）；

{"id":"opt3062581","issuedtutes1":["1","2","3"],
"issuedtutes2":["1","2","3"],
"issuedtutes3":["1","2","3"]}

但是所需的结果如下；

{"id":"opt471821","issuedtutes":["1","2","3"]},
{"id":"opt1215754","issuedtutes":["1","2","3"]},
{"id":"opt3062581","issuedtutes":["1","2","3"]}

无法弄清楚我想念的是什么。当我从函数中删除id部分时，这将返回{"id":"opt3062581","issuedtutes":["1","2","3"]}，这是最后一个列表中的数据。请帮忙。

上演名单列表的数量是动态的并且不是固定的。

您的预期输出看起来像一个对象列表，因此tutelists应该是一个列表，而不是对象。

jQuery(document).on("click", ".refno", function() {
  var ref = jQuery(this).data("ref");
  var refindex = jQuery(this).data("refindex");

  var i = 0;
  var tutelists = [];
  jQuery('.datarefindex_' + refindex).each(function() {
var subjid = jQuery(this).data("subjid");
i++;
  var tutearray = {};

tutearray["id"] = subjid;
tutearray["issuedtutes"] = jQuery("input[name=tuteset_" + refindex + "_" + subjid + "]:checked").map(function() {
  return this.value;
}).get();
  tutelists.push(tutearray);

  });
  var tutelists = JSON.stringify(tutelists);

  jQuery("#responsecontainer").html(tutelists);

});

Answer 2

您的id值将替换为新的值。请尝试使用push()数组方法使其可行。

jQuery(document).on("click", ".refno", function () {
    var ref = jQuery(this).data("ref");
    var refindex = jQuery(this).data("refindex");

    var i = 0;
    var tutelists =[];
    tutelistElement = {};
    jQuery('.datarefindex_'+ refindex ).each(function(){
        var subjid = jQuery(this).data("subjid");
        i++;

        tutelistElement["id"] = subjid;
        tutelistElement["issuedtutes"+i] = jQuery("input[name=tuteset_"+refindex+"_"+subjid+"]:checked").map(function () { return this.value; }).get();

    });
    tutelists.push(tutelistElement);
    var tutelists = JSON.stringify(tutelists);

    jQuery("#responsecontainer").html(tutelists);

});

jQuery每个循环仅给出第一个结果
