我是
javascript / jquery的新手.编写了以下脚本,它适用于Chrome 46.0.2490.80 m,但不适用于Firefox 42.0或IE 11.
格式为％< value_name>％的值是我正在使用的内容管理系统的预定义值.
格式为％< value_name>％的值是我正在使用的内容管理系统的预定义值.
如果布尔值“％asset_Metadata_register_button％”设置为0,或者在Date变量“eventDate”发生后的一天,该脚本应该隐藏按钮.否则显示按钮.
该脚本还应该在eventDate发生后更改按钮的文本和href值.
HTML
<p id="show"><a id="change" class="button" href="firstURl">Register</a></p>
使用Javascript
$(document).ready(function() {
// Boolean value from Show Registration Button Metadata field
var number = "%asset_Metadata_register_button%";
// variable for start date of event
var eventDate = new Date('%asset_attribute_start_date%');
// variable for date at present time
var now = new Date();
// variable for one day after present time
var oneDay = new Date('%asset_attribute_start_date%');
oneDay.setDate(oneDay.getDate() + 1);
// Hide button if Show Registration Button Metadata field is set to no,or for one day after Webinar took place. Otherwise show Button.
if (number == 1) {
if (eventDate < now && now < oneDay) {
document.getElementById("show").innerHTML = "(Webinar will be uploaded shortly)";
} else {
$('#show').show();
}
} else {
$('#show').hide();
}
// changes button text and link after webinar commences
if (eventDate > now) {
document.getElementById("change").innerHTML = "View Webinar";
document.getElementById("change").href = "secondURL";
}
});
解决方法
正如Jaromanda X所提到的那样,某些浏览器会出错.
您的代码如下所示：
// variable for start date of event
var eventDate = new Date('%asset_attribute_start_date%');
// variable for date at present time
var now = new Date();
//variable for one day after present time
var oneDay = new Date('%asset_attribute_start_date%');
oneDay.setDate(oneDay.getDate() + 1);
您可以将其替换为：
var dateTime = '%asset_attribute_start_date%';
var date = dateTime.substring(0,dateTime.indexOf(" "));
var time = dateTime.substring(dateTime.indexOf(" ")+1);
date = date.substring(date.indexOf("-")+1) + "-" + date.substring(0,date.indexOf("-"));
var eventDate = new Date(date + ' ' + time);
var oneDay = new Date();
oneDay.setDate(eventDate.getDate() + 1);
var now = new Date();
它的作用是将日期格式从“2015-11-04”替换为“11 -04-2015”.
