使用wordpress制作Javascript幻灯片

I'm making my first steps learning to code. I made some courses about html, css, javascript, php and MySql, and now, I decided to continue learning from the practice while I build a Wordpress child theme.

我正在学习编码的第一步。我做了一些关于html,css,javascript,php和MySql的课程,现在,我决定在构建一个Wordpress儿童主题时继续学习这个练习。

The thing is that I am building an image slideshow. And to start understanding how to make it I found this: http://www.w3schools.com/w3css/w3css_slideshow.asp.

问题是我正在构建一个图像幻灯片。并开始了解如何制作它我发现了这个:http://www.w3schools.com/w3css/w3css_slideshow.asp。

It's a simple and useful slideshow. It's really nice! But there are some problems if I want to implement it in Wordpress.

这是一个简单实用的幻灯片。这太好了!但是如果我想在Wordpress中实现它有一些问题。

I made a post type and using the Advanced Custom Fields plugin I created a Repeater Field. So that code would be something like this in Wordpress:

我做了一个帖子类型并使用高级自定义字段插件我创建了一个Repeater字段。所以在Wordpress中代码就像这样:

<?php get_header(); ?>

<script>

var slideIndex = 1;
showDivs(slideIndex);

function plusDivs(n) {
  showDivs(slideIndex += n);
}

function showDivs(n) {
  var i;
  var x = document.getElementsByClassName("mySlides");
  if (n > x.length) {slideIndex = 1}
  if (n < 1) {slideIndex = x.length}
  for (i = 0; i < x.length; i++) {
     x[i].style.display = "none";
  }
  x[slideIndex-1].style.display = "block";
}

</script>


<?php


if( have_rows('image') ):

    while ( have_rows('image') ) : the_row();


                if( get_sub_field('subimage') ) :

            echo '<div class="mySlides">' . get_sub_field('subimage') . '</div>';
          endif;

    endwhile;


endif;

?>

<a class="home-btn-left" onclick="plusDivs(-1)">❮</a>
<a class="home-btn-right" onclick="plusDivs(1)">❯</a>


</div>

<?php get_footer(); ?>

It works almost perfect! But now I have two problems:

它几乎完美!但现在我有两个问题:

1) Once I load my page to see the template. I see the first image overlaying the last image. I don't know why:

1)一旦我加载页面以查看模板。我看到第一张图片覆盖了最后一张图片。我不知道为什么:

2) At the end of the slideshow there is an empty slide. It looks like I have an empty subfield but no, I don't have empty subfields. I don't know why there is an empty slide.

2)在幻灯片放映结束时,有一张空幻灯片。看起来我有一个空的子字段,但没有,我没有空的子字段。我不知道为什么有一张空幻灯片。

Do you have some recommendation?

你有什么建议吗?

Thank you

I think the problem is the last closing DIV </div> just before your get_footer(). It's a simple html markup error that causes the browser to fail. Your code should look like this:

我认为问题是你的get_footer()之前的最后一个结束DIV 。这是一个简单的html标记错误导致浏览器失败。您的代码应如下所示:

<?php get_header(); ?>

<script>

var slideIndex = 1;

function plusDivs(n) {
  showDivs(slideIndex += n);
}

function showDivs(n) {
  var i;
  var x = document.getElementsByClassName("mySlides");
  if (n > x.length) {slideIndex = 1}
  if (n < 1) {slideIndex = x.length}
  for (i = 0; i < x.length; i++) {
     x[i].style.display = "none";
  }
  x[slideIndex-1].style.display = "block";
}

</script>


<?php

if( have_rows('image') ):
  while ( have_rows('image') ) : the_row();
    if( get_sub_field('subimage') ) :
      echo '<div class="mySlides">' . get_sub_field('subimage') . '</div>';
    endif;
  endwhile;
endif;

?>

<a class="home-btn-left" onclick="plusDivs(-1)">❮</a>
<a class="home-btn-right" onclick="plusDivs(1)">❯</a>

<script>
  showDivs(slideIndex);
</script>

<?php get_footer(); ?>

Please let me know if this doesn't fix your problem.

如果这不能解决您的问题,请告诉我。
