[英]Changing colour of a particular index in a table
A table has two rows and three columns. 一个表有两行三列。 The requirement is that if the sum of second and third column for a particular row is not equal to 12 than the background colou for same row but first column will change to red.
要求是,如果特定行的第二和第三列之和不等于12,而不是同一行的背景色,但第一列将变为红色。
Note: First column is having a text only. 注意:第一列仅包含文本。 Second and third columnns have textboxes containing integer values.
第二和第三列具有包含整数值的文本框。
Example: 例:
<table>
<tr>
<td>A</td>
<td>2</td>
<td>13</td>
</tr>
<tr>
<td>B</td>
<td>2</td>
<td>10</td>
</tr>
<tr>
<td>C</td>
<td>2</td>
<td>14</td>
</tr>
</table>
In the above example, the sum 2+13 and 2+14 are greater than 12, so the background colour of first for both of them should change to red colour. 在上面的示例中,总和2 + 13和2 + 14大于12,因此它们两个的first的背景色都应更改为红色。
You can simply do: 您可以简单地执行以下操作:
$('tr').each(function(i, row) {
// init sum for each new parsed row
var sum = 0;
// parse row children ('td')
$(this).children('td').each(function(j, col) {
if (j > 0) {
// sum all columns, except first
sum += parseInt($(col).text());
}
});
// check sum
if (sum != 12) {
// Change background here for first column of current row
$(row).find('td').first().css({
backgroundColor: 'red'
});
}
})
