无法使用按钮的onclick事件调用javascript函数

Question

My display.php file has the code for fetching data from database and display it in html table. 我的display.php文件具有用于从数据库中获取数据并将其显示在html表中的代码。 I want to display this table on my index page only in the <div> displayTable section and for that I've called the showTbale() using onclick of my button abc . 我只想在<div> displayTable部分中的索引页面上显示此表，为此，我使用按钮abc onclick调用了showTbale() 。 But the problem is that the function showTable() doesn't get called even though I've successfully called the logoutEmp() using the onclick of the logoutButton . 但是问题是，即使我已经使用logoutButton的onclick成功调用了logoutEmp()也无法调用showTable()函数。 I don't understand what's the problem. 我不明白这是什么问题。 Any help would be appreciated. 任何帮助，将不胜感激。

NOTE: I tried using form action to call display.php but it displays the table in another white page which I don't want. 注意：我尝试使用表单操作来调用display.php但它在另一个不需要的白页中显示该表。 Also I don't want to include display.php code in my index page. 我也不想在索引页面中包含display.php代码。

say this is my index file : 说这是我的索引文件：

<head>
<meta http-eqiv="X-UA-Compatible" content="IE=9,chrome=1">
<link rel="stylesheet" type="text/css" href="page_style.css">
<script src="jquery-1.10.1.js"></script>
</head>

<body>
<script>

function logoutEmp()
{
  window.location="saveLogout.php";
}   

function showTable()
{
  var month= $('#mnth: selected').val();
  alert (month);

  $("#displayTable").load("display.php",{ mnth: month});
}   

</script>

<h1>Employee Account</h1>

<div id="logoutEmp">
<button type="button" id="logoutButton" onclick="logoutEmp()">Logout</button>
</div>

<hr>

<div id="shw">
<select name="mnth">
<option value="Jan">January</option>
<option value="Feb">February</option>
<option value="Mar">March</option>
<option value="Apr">April</option>
<option value="May">May</option>
<option value="Jun">June</option>
<option value="Jul">July</option>
<option value="Aug">August</option>
<option value="Sep">September</option>
<option value="Oct">October</option>
<option value="Nov">November</option>
<option value="Dec">December</option>
</select>
<button type="button" id="abc" onclick="showTable()">Display</button> 


<div id="displayTable">
</div>

</div>

</body>
</html>

Answer 1

change your code like this: 像这样更改代码：

function logoutEmp(){
 window.location.href="saveLogout.php";
 }

You had an extra slash, and a syntax error. 您有一个额外的斜杠和语法错误。

Also, you should change showTable that was wrong as well : 此外，您还应该更改错误的showTable ：

function showTable()
{
  var month= $('#mnth').val();
  alert (month);

 $("#displayTable").load("display.php",{ mnth: month});
 }

And add your id to your select: 并将您的ID添加到您的选择中：

<select name="mnth" id="mnth">

Here is the demo my friend. 这是我的朋友的演示。

Answer 2

I guess: 我猜：

function logoutEmp()
{
 window.location="saveLogout.php";
 \}

that backslash should not be there: 反斜杠不应该存在：

function logoutEmp()
{
 window.location="saveLogout.php";
}

you can not call showTable() because in JavaScript if there is any error script after that error would not work. 您无法调用showTable()因为在JavaScript中，如果该错误之后没有任何错误脚本，该错误将不起作用。
