Question

当我将数据库中的参数传递给javascript函数时，我遇到了这个问题，我得到一个减少的数字，而且它与我期望出现的数字不同

传递的格式是（#### - ####）

<?php 
include 'connect.php';
 session_start();

if(isset($_SESSION['name']) && $_SESSION['name'] != "")
{

?>
<!DOCTYPE html>
<html>
<head>

<link rel="stylesheet" href="css/main.css" />
<script src="js/main.js"></script>

<body>

                </button>
            </a>

            <span style="float:left;">

echo "      </span>";
echo "      <br style='clear:both;'/>";
echo "</div>";


    }

}

}

?>
</div>
</body>
</html>
<?php
}
else
{
    echo "<script>alert('Please Login To Continue');window.open('index.php','_self');</script>";
}
?>

这是我的javascript代码

function showOverlay(id)
    {
        alert(id);
        document.getElementById(id).style['display'] = "block";
        document.getElementById(id).style['opacity'] = "1";
    }

我刚刚做了那个警告声明，所以我可以看到程序在javascript上传递了什么＆＃39 ps

我点击了第一个出现的抽象链接，你可以看到我回应了应该在作者之前传递然后传递的内容是在警报框中

我似乎无法发现这里的错误是我的mysql语句或javascript代码还是php代码

Answer 1

将ID添加到Abstract链接并将showOverlay(".$reference.")更改为onclick='showOverlay(this.dataset.articlenum)'请参阅下面的PHP行：

PHP

echo ($run['abstract'] != "" ? "<a class='options' data-articlenum='" . $reference . "' onclick='showOverlay(this.dataset.articlenum)'>Abstract</a><span style='margin:0px 5px;'>|</span>" : "" );
