将jQuery脚本与WordPress foreach循环一起使用 [英] Using jQuery script with WordPress foreach loop

问题描述

当前，我有这个脚本:

<?php $test = get_categories('taxonomy=item&type=things');?>

    <?php foreach($test as $stuff) : ?>
        <script type="text/javascript">
        jQuery(document).ready(function($) {
          var $things = <?php echo json_encode($stuff->name); ?>;
          console.log($things);
          $(".element").each(function() {
            var $state = $(this).attr("title");
            if ($things.indexOf($state) > -1) {
              $(this).addClass('current');
            }
          });
        });
        </script>
    <?php endforeach; ?>

这是可行的，但是我不确定如何将其从foreach循环中删除，以免它不会一遍又一遍地重复jQuery脚本.

Which is working, but I'm not sure how to get it out of the foreach loop so that it doesn't keep repeating the jQuery script over and over again.

总体而言，我正在尝试通过WordPress从get_categories中获取值，然后从数组中传递name值，然后在jQuery中进行检查以将一个类添加到div中的特定元素.

Overall, I'm trying to get the values out from the get_categories via WordPress, but then pass the name value from the array and then check that within jQuery to add a class to specific elements within a div.

我知道我可能会走错路，所以如果有人知道更好，更清洁的方法，我完全可以提出建议.

I know I'm probably going about the wrong way, so I'm completely open to suggestion if anyone knows a better, cleaner way of approaching this.

推荐答案

使用array_column()获取所有名称.下面未测试的代码

Use array_column() to get all the names. Not tested code below

<?php 
$test = get_categories('taxonomy=item&type=things');
$names = array_column($test, 'name'); ?>

<script type="text/javascript">
jQuery(document).ready(function($) {
  var $things = <?php echo json_encode($names); ?>;
  console.log($things);
  $(".element").each(function() {
    var $state = $(this).attr("title");
    if ($things.indexOf($state) > -1) {
      $(this).addClass('current');
    }
  });
});
</script>
