javascript - jQuery 每个循环只给出第一个结果

Question

我正在尝试生成一个数组，通过 jQuery 提交给 ajax 调用。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);

});

我收到的结果如下(我已选中每个列表中的前 3 个框)；

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

但是期望的结果如下；

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

无法弄清楚我错过了什么。当我从函数中删除 id 部分时，返回 {"id":"opt3062581","issuedtutes":["1","2","3"]} 这是最后一个列表中的数据。请帮忙。

类(class)列表的数量是动态的且不固定。

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一个对象。

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);

});
