我有一个包含多个div的页面,其中包含带有链接的图像,我想根据日期将其从不可点击变为可点击。例如 - 我有 5 天div (01.03.2016, 02.03.2016, 03.03.2016, 04.03.2016, 05.03.2016).在这些div中,我有带有链接的图像。
on 01.03.2016 - 只有div 1 可点击,所有其他
不可点击on 02.03.2016 - 只有div1 和div2 可点击,所有其他不能等等...
on 05.03.2016 - 所有五个div都可以点击
提前谢谢你
var divs = document.getElementsByClassName("date");
for (i = 0 ; i < divs.length ; i++) {
divs[i].style.pointerEvents = 'none';
}
for (i = 0 ; i < divs.length ; i++) {
var divDate = divs[i].id.split('.');
var date = new Date(divDate[2], divDate[1] - 1, divDate[0]);
if (date <= new Date()) {
divs[i].style.pointerEvents = 'auto';
}
}
<div class="date" id="01.03.2016">01.03.2016 <a href="ihttp://google.com"><img src="images/image1.jpg" alt="Google Image" width="138" height="138" class="img_rounded" /></a></div>
<div class="date" id="02.03.2016">02.03.2016 <a href="ihttp://google.com"><img src="images/image1.jpg" alt="Google Image" width="138" height="138" class="img_rounded" /></a></div>
<div class="date" id="03.03.2016">03.03.2016 <a href="ihttp://google.com"><img src="images/image1.jpg" alt="Google Image" width="138" height="138" class="img_rounded" /></a></div>
<div class="date" id="04.03.2016">04.03.2016 <a href="ihttp://google.com"><img src="images/image1.jpg" alt="Google Image" width="138" height="138" class="img_rounded" /></a></div>
<div class="date" id="09.03.2016">09.03.2016 <a href="ihttp://google.com"><img src="images/image1.jpg" alt="Google Image" width="138" height="138" class="img_rounded" /></a></div>
我会使用日期比较。也许是这样的:
.HTML
<div class="date">01.03.2016</div>
<div class="date">02.03.2016</div>
<div class="date">03.03.2016</div>
<div class="date">04.03.2016</div>
<div class="date">05.03.2016</div>
JavaScript:
var elms = document.getElementsByClassName("date");
for (var i = 0 ; i < elms.length ; i++)
{
var el = elms[i];
var dmy = el.innerHTML.split('.');
var date = new Date(dmy[2], dmy[1] - 1, dmy[0]);
if (date <= new Date()) {
el.style.backgroundColor = "yellow";
el.onclick = function () {
alert("you clicked on " + this.innerHTML)
};
}
}
演示这是一个JSFiddle
.HTML
<div class="date" id="First">01.03.2016</div>
<div class="date all" id="Second">02.03.2016</div>
<div class="date all three two" id="Third">03.03.2016</div>
<div class="date all three two one" id="Fourth">04.03.2016</div>
<div class="date all three two one zero" id="Fifth">05.03.2016</div>
在 JQuery 中禁用单击
$("#First").click(function(){
$(".all ").off('click');
}
$("#Second").click(function(){
$(".three ")off('click');
}
$("#Third").click(function(){
$(".two")off('click');
}
$("#Fourth").click(function(){
$(".one").off('click');
}
$("#Fifth").click(function(){
$(".zero")off('click');
}
或在 JQuery 中禁用div
$("#First").click(function(){
$(".date").removeAttr('disabled','disabled');
$(".all ").attr('disabled','disabled');
}
$("#Second").click(function(){
$(".date").removeAttr('disabled','disabled');
$(".three ").attr('disabled','disabled');
}
$("#Third").click(function(){
$(".date").removeAttr('disabled','disabled');
$(".two").attr('disabled','disabled');
}
$("#Fourth").click(function(){
$(".date").removeAttr('disabled','disabled');
$(".one").attr('disabled','disabled');
}
$("#Fifth").click(function(){
$(".date").removeAttr('disabled','disabled');
$(".zero").attr('disabled','disabled');
}
