问题描述
你好
因此，我试图显示图片库中的一幅图像作为默认图像，具体取决于月份.我已经创建了图片库，并且正在幻灯片"视图中使用它；我要显示的图像是本月的日历之一.我想要 例如，用户每月要查看适当的图片:3月中，3月日历图片应该是用户首先查看的图片，但是他/她仍然可以切换幻灯片.
So I am trying to display one image from a picture library as the default image depending on month. I have created the picture library and I am using it in Slides view; the image that I want displayed is one with the calendar of the present month. I want the user to see the appropriate picture each month, for example: in March the March calendar picture should be the first to be viewed by the user, however he/she can still switch slides.
到目前为止，我在脚本编辑器中插入了一些代码(该代码不起作用)，如下所示:
So far, I have some code that I inserted in a script editor (which is not working), as follows:
<html>
<body>
<script type="text/javascript">
var now = new Date();
var month = now.getMonth();
if (month == 1)
{
{document.write('<img src="January 2018.png">');
}
else if (month == 2)
{
{document.write('<img src="February 2018.png">');
}
else if (month == 3)
{
{document.write('<img src="March 2018.png">');
}
else if (month == 4)
{
{document.write('<img src="April 2018.png">');
}
else if (month == 5)
{
{document.write('<img src="May 2018.png">');
}
else if (month == 6)
{
{document.write('<img src="June 2018.png">');
}
else if (month == 7)
{
{document.write('<img src="July 2018.png">');
}
else if (month == 8)
{
{document.write('<img src="August 2018.png">');
}
else if (month == 9)
{
{document.write('<img src="September 2018.png">');
}
else if (month == 10)
{
{document.write('<img src="October 2018.png">');
}
else if (month == 11)
{
{document.write('<img src="November 2018.png">');
}
else
{
document.write('<img src="December 2017.png">');
}
</script>
</body>
</html>有人可以帮我继续吗?
推荐答案
我们可以在页面加载中使用Jquery覆盖幻灯片Web部件的默认imgae标签，如下所示:
We can override the slide web part default imgae tag with Jquery in Page load like below:
<script type="text/javascript" src="https://code.jquery.com/jquery-1.10.2.js"></script>
<script type="text/javascript">
var now=new Date();
var month=now.getMonth()+1;
