我正在尝试在 iframe 中显示我的登录信息,该 iframe 加载在带有灰色背景的起始页面中间,但是我在处理 iframe 的目标时遇到问题,事情应该如下工作:1-如果用户成功登录到家页面应在父窗口中加载 2- 如果出错,错误消息应显示在 iframe 本身中。
我的代码:
<div id="cover5" onclick="javascript:cover5();">
<iframe name="warning" src="SignIn.php" id="warning" onclick="javascript:cover5();">
</iframe>
</div>
登录.php
<html>
<head>
<script type='text/javascript'>
function valid(){
if(document.getElementById('username').value.toString().length>=1 || document.getElementById('password').value.toString().length>=1){
return true;
}
else{
alert("The Combination of username and password are Incorrect !");
return false;
}
}
</script>
<script type='text/javascript'>
function ChangeTarget() {
document.getElementById("login").prop("target", "_parent")
}
</script>
<script type='text/javascript'>
function ChangeText(text) {
document.getElementById("label1").innerHTML= text;
}
</script>
<title></title>
</head>
<body>
<form name="login" id='login' target='_self' method='post' accept-charset='UTF-8'>
<fieldset>
<legend>SignIn</legend>
<input type='hidden' name='submitted' id='submitted' value='1'/>
<label for='username' >Email:</label>
<input type='text' name='email' id='username' maxlength="50" /> <br />
<label for='password' >Password:</label>
<input type='password' name='password' id='password' maxlength="50" /> <br />
<br /> <label id="label1" style="color: red"></label> <br />
<input type='submit' name='Submit' value='Login'/> <br />
<a href='resetPassword1.php'> Forgot/Reset Password? Click Here</a>
</fieldset>
</form>
但是,目标不会被称为 inisde php 代码的 ChangeTarget() 方法更改,所以现在的问题是所有内容都加载到 iframe 内或父窗口内的所有内容。有谁知道如何解决这个问题?
服务器端脚本:
mysql_select_db("mydb",$check);
$email = $_POST['email']; //username that will be submit from a form
$password = $_POST['password']; //password that will be submit from a form
// if(mysql_num_rows($temp_privileges_id)== 1) //if the id found that means that the user is already assigned to a conference
// {
echo '<script type="text/javascript">',
'ChangeTarget();',
'</script>';
header('Location: main.php'); // transefer to home page with variable username
}
