将变量添加到 Jquery 后出现语法错误 - Syntax error after adding a variable into Jquery

Syntax error after adding a variable into Jquery

本文关键字：语法错误 Jquery 变量添加 | 更新日期: 2023-09-27

我使用Jquery脚本制作了一个下拉div。

$("#top<?php echo $this->$i?>").click(function(){
        $("#down<?php echo $this->$i?>").slideToggle("slow","swing",500);
      });
    });

这是在谷歌浏览器中给出语法错误。在检查器中，它显示为"#top
.波纹管一个工作正常。

$("#top<?php echo "one"?>).click(function(){
        $("#down<?php echo "two"?>").slideToggle("slow","swing",500);
      });
    });

为什么会发生这种情况，如果我犯了错误，如何解决它。

这是我的 phtml 文件。

<!doctype html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="mycss.css">
<script src="jquery-1.11.1.js"></script>
<script type="text/javascript">
$(document).ready(function(){
     $("#top<?php echo $this->i;?>").click(function(){
        $("#down<?php echo $this->i;?>").slideToggle("slow","swing",500);
      });
    });
</script>

<?php echo $this->$i?>

实际上应该是

<?php echo $this->i ?>

没有i的$标志
