同时对两个相似的表进行排序

Question

我有两个具有完全相同列的表。这些表格彼此相邻放置。目前他们分开排序。我希望他们一起排序。即当我点击表1的第一列标题时，两个表都应该被排序，就好像它们都是单个表一样。

这是我使用

function SortableTable (tableEl) { 

this.tbody = tableEl.getElementsByTagName('tbody'); 
this.thead = tableEl.getElementsByTagName('thead'); 
this.tfoot = tableEl.getElementsByTagName('tfoot'); 

this.getInnerText = function (el) { 
    if (typeof(el.textContent) != 'undefined') return el.textContent; 
    if (typeof(el.innerText) != 'undefined') return el.innerText; 
    if (typeof(el.innerHTML) == 'string') return el.innerHTML.replace(/<[^<>]+>/g,''); 
} 

this.getParent = function (el, pTagName) { 
    if (el == null) return null; 
    else if (el.nodeType == 1 && el.tagName.toLowerCase() == pTagName.toLowerCase()) 
     return el; 
    else 
     return this.getParent(el.parentNode, pTagName); 
} 

this.sort = function (cell) { 

    var column = cell.cellIndex; 
    var itm = this.getInnerText(this.tbody[0].rows[1].cells[column]); 
    var sortfn = this.sortCaseInsensitive; 

    if (itm.match(/\d\d[-]+\d\d[-]+\d\d\d\d/)) sortfn = this.sortDate; // date format mm-dd-yyyy 
    if (itm.replace(/^\s+|\s+$/g,"").match(/^[\d\.]+$/)) sortfn = this.sortNumeric; 

    this.sortColumnIndex = column; 

    var newRows = new Array(); 
    for (j = 0; j < this.tbody[0].rows.length; j++) { 
     newRows[j] = this.tbody[0].rows[j]; 
    } 

    newRows.sort(sortfn); 

    if (cell.getAttribute("sortdir") == 'down') { 
     newRows.reverse(); 
     cell.setAttribute('sortdir','up'); 
    } else { 
     cell.setAttribute('sortdir','down'); 
    } 

    for (i=0;i<newRows.length;i++) { 
     this.tbody[0].appendChild(newRows[i]); 
    } 

} 

this.sortCaseInsensitive = function(a,b) { 
    aa = thisObject.getInnerText(a.cells[thisObject.sortColumnIndex]).toLowerCase(); 
    bb = thisObject.getInnerText(b.cells[thisObject.sortColumnIndex]).toLowerCase(); 
    if (aa==bb) return 0; 
    if (aa<bb) return -1; 
    return 1; 
} 

this.sortDate = function(a,b) { 
    aa = thisObject.getInnerText(a.cells[thisObject.sortColumnIndex]); 
    bb = thisObject.getInnerText(b.cells[thisObject.sortColumnIndex]); 
    date1 = aa.substr(6,4)+aa.substr(3,2)+aa.substr(0,2); 
    date2 = bb.substr(6,4)+bb.substr(3,2)+bb.substr(0,2); 
    if (date1==date2) return 0; 
    if (date1<date2) return -1; 
    return 1; 
} 

this.sortNumeric = function(a,b) { 
    aa = parseFloat(thisObject.getInnerText(a.cells[thisObject.sortColumnIndex])); 
    if (isNaN(aa)) aa = 0; 
    bb = parseFloat(thisObject.getInnerText(b.cells[thisObject.sortColumnIndex])); 
    if (isNaN(bb)) bb = 0; 
    return aa-bb; 
} 

// define variables 
var thisObject = this; 
var sortSection = this.thead; 

// constructor actions 
if (!(this.tbody && this.tbody[0].rows && this.tbody[0].rows.length > 0)) return; 

if (sortSection && sortSection[0].rows && sortSection[0].rows.length > 0) { 
    var sortRow = sortSection[0].rows[0]; 
} else { 
    return; 
} 

for (var i=0; i<sortRow.cells.length; i++) { 
    sortRow.cells[i].sTable = this; 
    sortRow.cells[i].onclick = function() { 
     this.sTable.sort(this); 
     return false; 
    } 
} 

} 

的.js文件只是有两列，并有可能保持不变。一些想法将非常感激。

我不太关注HTML（因为您没有包含任何HTML），所以我在这里创建了一个简单的版本，并在表中实现了一种排序。其基本思想是将表中的所有数据收集到单个JavaScript数据结构中，对javascript数据结构进行排序，然后将所有数据放回到表中。

这使得排序更简单，并且唯一需要处理多个表的复杂性的地方是在检索数据并将其放回表中时。你可以看到它在这里工作：http://jsfiddle.net/jfriend00/Z5ywA/。只需点击列标题即可查看按该列排序的两个表。

的代码是这样的：

function sortTables(colNum) { 
    var t1 = document.getElementById("table1"); 
    var t2 = document.getElementById("table2"); 
    var data = [], sortFn; 

    function sortAlpha(a, b) { 
     // deal with empty strings 
     var aa = a[colNum].data, bb = b[colNum].data; 
     if (!aa) { 
      return(!bb ? 0 : -1); 
     } else if (!bb){ 
      return(1); 
     } else { 
      return(aa.localeCompare(bb)); 
     } 
    } 

    function sortNumeric(a, b) { 
     // deal with possibly empty strings 
     var aa = a[colNum].data, bb = b[colNum].data; 
     if (typeof aa == "string" || typeof bb == "string") { 
      return(sortAlpha(a, b)); 
     } else { 
      return(aa - bb); 
     } 
    } 

    // get the data 
    function getData(table) { 
     var cells, rowData, matches, item, cellData; 
     var rows = table.getElementsByTagName("tbody")[0].getElementsByTagName("tr"); 
     for (var i = 0; i < rows.length; i++) { 
      rowData = []; 
      cells = rows[i].getElementsByTagName("td"); 
      for (var j = 0; j < cells.length; j++) { 
       // add each cell in the row to the rowData data structure 
       item = {}; 
       item.origStr = cells[j].textContent || cells[j].innerText; 
       cellData = item.origStr.replace(/^\s*|\s*$/g, "").toLowerCase(); 
       if (cellData.match(/^[\d\.]+$/)) { 
        cellData= parseFloat(cellData); 
       } else if (matches = cellData.match(/^(\d+)-(\d+)-(\d+)$/)) { 
        cellData= new Date(
         parseInt(matches[3], 10), 
         parseInt(matches[1], 10) - 1, 
         parseInt(matches[2], 10) 
        ); 
       } 
       item.data = cellData; 
       // determine the type of sort based on the first cell we find 
       // with data in the column that we're sorting 
       if (!sortFn && item.data !== "" && j == colNum) { 
        if (typeof item.data == "number" || typeof item.data == "object") { 
         sortFn = sortNumeric; 
        } else { 
         sortFn = sortAlpha; 
        } 
       } 
       rowData.push(item); 
      } 
      // add each row to the overall data structure 
      data.push(rowData); 
     } 
    } 

    // put data back into the tables 
    function putData(table) { 
     var cells, rowData, item; 
     var rows = table.getElementsByTagName("tbody")[0].getElementsByTagName("tr"); 
     for (var i = 0; i < rows.length; i++) { 
      cells = rows[i].getElementsByTagName("td"); 
      for (var j = 0; j < cells.length; j++) { 
       // add each cell in the row to the rowData data structure 
       cells[j].innerHTML = data[0][j].origStr; 
      } 
      // remove this row 
      data.shift(); 
     } 
    } 


    getData(t1); 
    getData(t2); 
    data.sort(sortFn); 
    putData(t1); 
    putData(t2);   

    return(false); 
}
