Question

我有2个小提琴。

在第一个（JSFiddle 1）中，我创建了一个新表并保存进入localStorage
在第二个（JSFiddle 2）中，我创建了一个复制行功能（选定的行并将其复制到选定的表格中。）

我的目标是将两个小提琴合二为一，让您：

添加新表[在JSFiddle 1上可用]
添加表时，有一个'复制到表1'选项[可在JSFiddle 2上使用]
可以选择行，然后使用该选项将其复制到选定的表中。 [可在JSFiddle 2上找到]

我需要删除它，并使用代码$('#table' + localStorage.Index).dataTable({...})

将其替换为新的表格功能

 $('#table2').dataTable({
    "data": localStorage.getItem('dataSet_table2') ? JSON.parse(localStorage.getItem('dataSet_table2')) : [], //changed here
    "columns": [{
      "title": "First Name"
    }, {
      "title": "Last Name"
    }, {
      "title": "Action"
    }],
    "bStateSave": true,
    "stateSave": true,
    "bPaginate": false,
    "bLengthChange": false,
    "bFilter": false,
    "bInfo": false,
    "bAutoWidth": false
  });

我花了很多时间在这上面，但我遇到了一些问题：

重新加载时，我无法第二次选择行。
无法复制行。

问我没有解释过这个问题，我会在这里和小提琴中解决它。

Answer 1

好的，我正在使用您的代码2作为起点，将代码1与代码2合并。

参见工作示例：

https://jsfiddle.net/mgsrzzye/1/

首先，我们需要在页面加载时检查本地存储，如果存在则在页面上打印表。

$(document).ready(function(){
        var localtbl = localStorage.getItem('tableList');

    var resultTable = [];
    if(localtbl !== undefined && localtbl !== ''){
    resultTable = JSON.parse(localtbl);
    }
        $.each(resultTable, function(i,v){
                $('#table1_wrapper').append(v.table);

    $('table[id^="table'+(i+2)+'"]').dataTable({
      "data": localStorage.getItem('dataSet_table' + (i+2)) ? JSON.parse(localStorage.getItem('dataSet_table' + (i+2))) : [], //changed here
      "columns": [{
        "title": "First Name"
      }, {
        "title": "Last Name"
      }, {
        "title": "Action"
      }],
      "bStateSave": true,
      "stateSave": true,
      "bPaginate": false,
      "bLengthChange": false,
      "bFilter": false,
      "bInfo": false,
      "bAutoWidth": false
    });

      })
})

然后，我们需要复制代码1以添加新表，并进行一些更改。

/* CREATE TABLE FITURE */
$('.submitButton').click(function() {

  var tblcount = ($('table[id^="table"]').length + 1);

    var addTable = '<br><button class="btn btn-success" id="copyToTable'+tblcount+'"> Copy To Table '+(tblcount)+'</button>' +
    '<h3 style="color:red;">Table '+(tblcount)+'</h3>' +
      '<table id="table'+tblcount+'" class="table table-striped table-bordered" cellspacing="0" width="100%"></table>';
    var getTbl = localStorage.getItem("tableList");
    var resultTable = [];
    if(getTbl !== undefined && getTbl !== ''){
    resultTable = JSON.parse(getTbl);
    }
    let newtableHTML = addTable;
    resultTable.push({
      table: newtableHTML
    });
    // save the new resultFolder array
    localStorage.setItem("tableList", JSON.stringify(resultTable));

  //console.log(tblcount);
  $('#table' + (tblcount-1) + '_wrapper').after(addTable);

  $('#table' + (tblcount)).dataTable({
    "data": localStorage.getItem('dataSet_table' + tblcount) ? JSON.parse(localStorage.getItem('dataSet_table' + tblcount)) : [], //changed here
    "columns": [{
      "title": "First Name"
    }, {
      "title": "Last Name"
    }, {
      "title": "Action"
    }],
    "bStateSave": true,
    "stateSave": true,
    "bPaginate": false,
    "bLengthChange": false,
    "bFilter": false,
    "bInfo": false,
    "bAutoWidth": false
  });


}); // submitButton func

最后一个，我们需要使用body，因为有时候我们添加了动态表。

$('body').on('click', 'button[id^="copyToTable"]', function(){
  let $elem = $(this);
  var table = $("#table" + $elem.attr('id').replace(/[a-zA-Z]/ig, ''));
  var tbl_id = table.attr('id');

  var $row = mainTable.find(".selected");
  if (!$row.length) {
    console.log('You must select some rows to copy first');
    return;
  } else {
    var r = confirm("Copy to table " + tbl_id + "?");
    var table_to_copy = table.dataTable();
    if (r == true) {
      copyRows(mainTable, table_to_copy);
      console.log("Copied!");
      setTimeout('console.clear()', 2000);
    }
  }
})

在一个项目/小提琴中组合'添加表'和'保存副本行'
