Question

我想传递四个参数事件，$ row ['title']，$ row ['username']和$ row ['date']。

<?php
echo "<script>
  function increasevotes(e,location,user,date)
  {
    e.preventDefault();
    console.log(\"Hi!\");
  }
  </script>";

//I've proper code here for fetching the mySQL query results into $rows and that part is working perfectly.

while($rows=mysqli_fetch_array($result))
{
if($rows['public']=="yes")
{echo "<span class=\"right\" id=\"nolikes\">{$rows['vote']}</span><a href=\"\" onclick=\"increasevotes(event,\"{$rows['title']}\",\"{$rows['username']}\",\"{$rows['date']}\")\"><img src=\"img/like.png\" class=\"right\" width=\"30\" height=\"30\"/></a>";
}
?>

实际上正在做的是，页面正在刷新。当我单击查看源页面时，会显示：

<span class="right" id="nolikes">0</span>
<a href="" onclick="increasevotes(event,"chennai","venkat","01/07/2017")"><img src="img/like.png" class="right" width="30" height="30"/>
</a>

Answer 1

将功能参数的双引号更改为单引号

onclick="increasevotes(event,'chennai','venkat','01/07/2017')"

或使用\来转义引号。

为什么以下onclick函数没有执行？
