我已经写了一个js代码来删除第31个日期列。
$(document).ready(function() {
$("#search").click(function() {
var e = document.getElementById("selMonth");
var monthSelect = e.options[e.selectedIndex].value;
var tid = null;
if(
$(this).value() == '4'||
$(this).value() == '6'||
$(this).value() == '9'||
$(this).value() == '11'
) {
$('#Production_monitor thead tr td').each(function (event) {
tid = $(this).attr('id');
if($(this).text() == '31'){
$('#' + tid).remove();
}
});
}
if($(this).value() == '2') {
$('#Production_monitor thead tr td').each(function (event) {
tid = $(this).attr('id');
if($(this).text() == '31'){
$('#' + tid).remove();
}
if($(this).text() == '30'){
$('#' + tid).remove();
}
});
}
prodmonitor(monthSelect);
});
});
和html代码如下。 我想在需要显示4月，6月，9月，11月的数据时动态删除31st日期列，并删除2月的31st和30th列。

但是它不起作用。请帮助我。
答案 0 :(得分：0)
以下行将只删除一个元素，很可能此元素在表thead中，并且不会影响整个列。
$('#' + tid).remove();
您需要做的是从整个表格中删除第31列。
为此，如果所有nth-child元素位于其<td>父元素的第31位，您将使用<tr>删除所有元素。
if($(this).text()=='31'){
$('#Production_monitor tr td:nth-child(31)').remove();
}
答案 1 :(得分：0)
尝试此代码
$(document).ready(function() {
$("#search").click(function() {
var monthSelect = $("#selMonth").val();
console.log(monthSelect);
//var monthSelect = e.options[e.selectedIndex].value;
var tid = null;
if(monthSelect == '4'|| monthSelect == '6'|| monthSelect == '9'|| monthSelect == '11') {
$('#Production_monitor thead tr th').each(function (event) {
if($(this).text() == '31'){
$(this).remove();
}
});
}
if(monthSelect == '2') {
$('#Production_monitor thead tr td').each(function (event) {
tid = $(this).attr('id');
if($(this).text() == '31'){
$(this).remove();
}
if($(this).text() == '30'){
$(this).remove();
}
});
}
});
});
