Question

for (var i = 0; row = tableAppointment.rows[i]; i++) { 
    for (var j = 0; col = row.cells[j]; j++) { 
    //iterate through columns

    } 
} 

如何遍历第三个单元格具有rowspan属性的每一行。

Answer 1

这会给你所有对他们有这样的元素<tr>的：

$('td:nth-child(3)[rowspan]').parent()

Answer 2

像这样的东西应该工作

$('tr').filter(function() { 
    return $('td:eq(2)',this).attr('rowspan') !== undefined; 
}).css('border', '1px solid red')​​​​​​​​​​​​​​​​​​​​;​

Answer 3

你可以做到这一点Y：

if (cell[2].hasAttribute('rowspan')) { 
    // do something here 
} 

用途element.hasAttribute()

Answer 4

$("tr").filter(function() { 
    return this.cells[2].hasAttribute("rowspan"); 
});

或者

for (var i = 0; row = tableAppointment.rows[i]; i++) { 
    if(row.cells[2].hasAttribute("rowspan") { 
     //This is a row that matches 
    } 
} 

Answer 5

Array.prototype.slice.call(tableAppointment.rows). 
    filter(function(row) { return row.cells[2].rowSpan > 1; }). 
    forEach(function(row) { 
     // do something with row 
    }); 

Whoaaa，看妈妈，没有jQuery的！

Answer 6

$('td:nth-child(3)[rowspan]').parent() 

Answer 7

$('td:nth-child(3)[rowspan]').parent()
