我想做一个小功能,可以用jQuery(或PHP / Ajax)置换表的2个单元格。
假设我有下表:
<table class="table">
<tr>
<td class="btn" data-cellN="1">
01
</td>
<td class="btn" data-cellN="2">
02
</td>
</tr>
<tr>
<td class="btn" data-cellN="3">
05
</td>
<td class="btn" data-cellN="4">
06
</td>
</tr>
</table>
如何选择2个细胞并进行置换?
编辑:
尽管如此,由于您的建议,我还是通过了该功能。我第一次遇到来自c1 c2 c3变量的怪异错误,这是可行的,我不知道为什么,
有人可以帮我完成我的功能吗?
这是我的Javascript :(包装在文档中)
var nbbuttonclicked=0; // to trigger the movecell function after the second button was clicked
var count=0; //Number of tinme we moved a cell
var table = {
c1:null,
c2:null,
c3:null,
check: function(){
$('td').on('click', function(){ //When the user click on a button we verify if he already clicked on this button
if( $(this).hasClass('btn-info') ) {
//If yes, then remove the class and variable c1
$(this).removeClass('btn-info');
table.c1=0;
nbbuttonclicked--;
}else{
//if no, then add a class to show him it is clicked and remember the value of the cell
$(this).addClass('btn-info');
if( typeof table.c1 === 'undefined' || table.c1===null) {
table.c1 = $(this);
console.log('c1:'+table.c1.html());
}else{
table.c2 = $(this);
console.log('c2:'+table.c2.html());
}
nbbuttonclicked++;
if( nbbuttonclicked==2 ) {
table.movecell(table.c1,table.c2); // we trigger the function to permute the values
}
}
});
},
movecell: function(c1, c2){
//We reset that variable for the next move
nbbuttonclicked=0;
//we move the cells
table.c3=c1.html();
c1.html(c2.html());
c2.html(table.c3)
c1.removeClass('btn-info');
c2.removeClass('btn-info');
table.c1=table.c2=table.c3=c1=c2=null;
},
// movecell: function(c1, c2){
// We check if the cells.html() are = to data-cellN. If yes, you won
// foreach()
// },
// var row = $('table tr:nth-child(1)')[0];
// moveCell(row, 0, 3);
};
table.check();

最佳答案
试试这个代码:
var cell0,
cell1,
next,
row0,
row1;
$('td').on('click', function() {
if(!cell0) {
cell0 = this;
row0 = cell0.parentNode;
return;
} else if(!cell1) {
cell1 = this;
row1 = cell1.parentNode;
// === Switch cells ===
next = cell0.nextSibling;
row1.insertBefore(cell0, cell1);
row0.insertBefore(cell1, next);
// ====================
row0 = row1 = cell0 = cell1 = next = null;
}
});

单击一个单元格,然后单击另一个单元格,然后查看它们是否已切换:)
