[英]JQuery datatable link onclick event
I have a jquery datatable that contains multiple columns and rows as below. 我有一个jquery数据表,包含多个列和行,如下所示。
<table>
<thead>
<tr>
<td>Name</td>
<td>Class</td>
<td>Action</td>
<td>Score</td>
<td>Corrected Score</td>
</tr>
</thead>
<tbody>
<tr>
<td>Student1</td>
<td>Math</td>
<td><a href="#">Add 5</a>
</td>
<td>73</td>
<td>
<input type="text" id="1_final_score" />
</td>
</tr>
<tr>
<td>Student2</td>
<td>Biology</td>
<td><a href="#">Add 5</a>
</td>
<td>84</td>
<td>
<input type="text" id="2_final_score" />
</td>
</tr>
<tr>
<td>Student3</td>
<td>History</td>
<td><a href="#">Add 5</a>
</td>
<td>50</td>
<td>
<input type="text" id="3_final_score" />
</td>
</tr>
</tbody>
When i click on the "Add 5" link, I want to add 5 to the score in the corresponding row and insert the result in the final score input field. 当我点击“添加5”链接时,我想在相应行中的分数中添加5并将结果插入最终分数输入字段。 I have tried using the jquery row-select feature, but am unable to figure out how to accomplish the above. 我已经尝试使用jquery行选择功能,但我无法弄清楚如何完成上述操作。
$(document).ready(function () {
$('table').find('a').click(function () {
var original = parseInt($(this).parents('tr').find('td:nth-child(4)').text()) + 5;
$(this).parents('tr').find('input[type=text]').val(original);
});
});
Try with this 试试这个
$('a:contains("Add 5")').click(function(){
$(this).parents('tr').find('td input:text').val(+$(this).parent().next('td').text() + 5 )
});
