- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我写了一个 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);
});
});
html代码如下。每当我需要显示 4 月、6 月、9 月、11 月的数据以及删除 2 月的第 31 和 30 列时,我想动态删除第 31 个日期列。

但它不起作用。请帮助我。
最佳答案
试试这段代码
$(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();
}
});
}
});
});
