FCKEditor中表格列以及多行列無法合并的解決辦法

Posted on 2007-08-09 18:47 姜海龍閱讀(879) 評論(0) 編輯收藏所屬分類: JAVASCRIPT

FCKEditor2.4.2版本中并不支持列的合并，下面是原代碼：

FCKTableHandler.MergeCells = function()
2

{
3

// Get all selected cells.
4

var aCells = FCKTableHandler.GetSelectedCells() ;
5

// At least 2 cells must be selected.
7

if ( aCells.length < 2 )
8

return ;
9

// The merge can occour only if the selected cells are from the same row.
11

if ( aCells[0].parentNode != aCells[aCells.length-1].parentNode )
12

return ;
13

// Calculate the new colSpan for the first cell.
15

var iColSpan = isNaN( aCells[0].colSpan ) ? 1 : aCells[0].colSpan ;
16

var sHtml = '' ;
18

var oCellsContents = FCK.EditorDocument.createDocumentFragment() ;
19

for ( var i = aCells.length - 1 ; i >= 0 ; i-- )
21

{
22

var eCell = aCells[i] ;
23

// Move its contents to the document fragment.
25

for ( var c = eCell.childNodes.length - 1 ; c >= 0 ; c-- )
26

{
27

var eChild = eCell.removeChild( eCell.childNodes[c] ) ;
28

if ( ( eChild.hasAttribute && eChild.hasAttribute('_moz_editor_bogus_node') ) || ( eChild.getAttribute && eChild.getAttribute( 'type', 2 ) == '_moz' ) )
30

continue ;
31

oCellsContents.insertBefore( eChild, oCellsContents.firstChild ) ;
33

}
34

if ( i > 0 )
36

{
37

// Accumulate the colspan of the cell.
38

iColSpan += isNaN( eCell.colSpan ) ? 1 : eCell.colSpan ;
39

// Delete the cell.
41

FCKTableHandler.DeleteCell( eCell ) ;
42

}
43

}
44

// Set the innerHTML of the remaining cell (the first one).
46

aCells[0].colSpan = iColSpan ;
47

if ( FCKBrowserInfo.IsGecko && oCellsContents.childNodes.length == 0 )
49

aCells[0].innerHTML = GECKO_BOGUS ;
50

else
51

aCells[0].appendChild( oCellsContents ) ;
52

}

第10行代碼對列合并做了限制，下面是修改的代碼：

FCKTableHandler.MergeCells = function()
2

{
3

// Get all selected cells.
4

var aCells = FCKTableHandler.GetSelectedCells() ;
5

// At least 2 cells must be selected.
7

if ( aCells.length < 2 )
8

return ;
9

// The merge can occour only if the selected cells are from the same row.
11

//if ( aCells[0].parentNode != aCells[aCells.length-1].parentNode ){
12

// alert("xx");
13

// return ;
14

//}
15

//*********************************************************************

//在IE下合并單元格修改，主要針對上下單元格不能合并的問題。

var iLen = aCells.length;
20

var iStartCol = aCells[0].cellIndex ;
21

var iStartRow = aCells[0].parentElement.rowIndex ;
22

var iEndCol = aCells[iLen-1].cellIndex ;
24

var iEndRow = aCells[iLen-1].parentElement.rowIndex ;
25

var eCells = new Array();
27

var j = 0;
28

for(var i = 0; i < iLen; i++){
30

if(aCells[i].cellIndex >= iStartCol && aCells[i].cellIndex <= iEndCol){
31

eCells[j] = aCells[i];
32

j++;
33

}
34

}
35

aCells[0].colSpan = iEndCol - iStartCol + 1;
37

aCells[0].rowSpan = iEndRow - iStartRow + 1;
38

for (var i = 1; i < j; i++){
40

eCells[i].parentElement.removeChild(eCells[i]);
41

}
42

//alert(aCells[0].rowSpan);
44

//alert(aCells[0].parentElement.parentElement.innerHTML);
45

}
