更改表的单元格值

标签: javascript php html

我想在点击该值时更改表格的单元格值。该单元格的默认值为“0”。当我点击它时,我想将其更改为“1”,将“1”更改为“0”。我是网络开发的新手。

如果有人能提供帮助,我们将非常感激。

<td onclick = "this.innerHTML=Math.abs(parseInt(this.innerHTML) - 1);">0</td>

答案 1 :(得分:0)

$("td").click(function(){
  value = parseInt($(this).text());
  value = (value > 0)? 0 : 1;
  $(this).text(value);
});

那就是它。

在jQuery中我会这样做

$('.target').click(function () {
    var target = $('.target').html();
    if (target == 0) {
        $('.target').html(1);
    }
    if (target == 1) {
        $('.target').html(0);
    }
})

在html中,目标td被归类为&#34; target&#34;
