当点击TD.gantt元素时,我们希望jQuery从input [name ='line_config']标记中获取值.我们尝试以下jQuery代码,但val()返回'undefined':
$(document).ready(function() {
function sum_day(tag, status, column) {
var total_day = 0;
var index_pos = 0;
var values = 0;
values = tag.closest('tr').children("input[name='line_config']").val();
alert(values); //Return undefined
return total_day;
}
$('td.gantt').click(function() {
var gantt_tag = $('td.preop');
$(this).toggleClass('preop');
sum_day(gantt_tag, 'preop', $(this).index());
});
});

我们是否正确的价值方式?如果有人可以帮助我们,我们感谢...... =)
注意jquery.children()只会返回直接/直接子节点,并且由于您的输入不是直接/直接子节点,因此<TR> 您将无法获得任何输入.
我可以建议这样的事情
$("input[name='line_config']", tag.closest('tr'))
