javascript - 选择items ids到同一行input单独保存

Question

我正在尝试创建一个界面，我可以在其中为每一行选择元素并单独保存(或在必要时保存整个页面)。

在上面的例子中，第一行是正确的，但是第二行应该只是“ru”，它也从第一行带来相同的内容..

如下例，由于我对整个页面使用相同的函数，但我在为每一行分隔元素时遇到了一些麻烦:

$(function() {
  var selec = [];
  $('#list li').click(function() {

    if ($(this).hasClass('gray')) {
      $(this).addClass("blue").removeClass("gray");
    } else {
      $(this).addClass("gray").removeClass("blue");
    }

    var this_row = $(this).closest('tr').attr('row-id');
    var this_lang = $(this).attr('data-lang');

    if ($(this).hasClass('blue')) {
      selec.push(this_lang);
    } else {
      var index = selec.indexOf(this_lang);
      selec.splice(index, 1);
    }
    $('#to_save_' + this_row).val(selec);
    return false;
  });

});

.tb table tr td {
  border: 1px solid #ccc;
}
.minitag:hover {
  background-color: #fff !important;
  color: #ccc !important;
  border: 1px solid #EE725C !important;
  text-shadow: 0 1px #A32D16 !important;
  cursor: pointer;
  opacity: 0.7;
}
.minitag {
  -webkit-border-radius: 3px;
  -moz-border-radius: 3px;
  border-radius: 3px;
  font-size: 10px;
  background-color: #FFB600;
  border: 1px solid #b62435;
  text-shadow: 0 1px #ccc;
  color: #000;
  font-weight: 500;
  margin: 0 2px 2px 0;
  display: inline-block;
  padding: 0 2px;
  cursor: default;
}
.minitag.blue {
  background-color: #4CABDA !important;
  border: 1px solid #296888 !important;
  text-shadow: 0 1px #296888 !important;
  color: #ffffff !important;
}
.selected {
  background-color: #EE725C !important;
  color: #fff;
  border: 1px solid #EE725C !important;
  text-shadow: 0 1px #A32D16 !important;
  cursor: pointer;
}

有什么建议吗？

Answer 1

您有全局选择，它包含所有值，这里是为每一行保留不同数组的对象。

$(function() {
  var selec = {};
  $('#list li').click(function() {
    if ($(this).hasClass('gray')) {
      $(this).addClass("blue").removeClass("gray");
    } else {
      $(this).addClass("gray").removeClass("blue");
    }

    var this_row = $(this).closest('tr').attr('row-id');
    var this_lang = $(this).attr('data-lang');
    if(!selec[this_row]) selec[this_row] = [];

    if ($(this).hasClass('blue')) {
      selec[this_row].push(this_lang);
    } else {
      var index = selec[this_row].indexOf(this_lang);
      selec[this_row].splice(index, 1);
    }
    $('#to_save_' + this_row).val(selec[this_row]);

    return false;
  });  
});
