问题描述
<html>
<head>
<meta name="datetime" content="Date09-09-2011-Time10-07-16">
<script type="text/javascript" language="javascript">
function GetValue()
{
var arrayOfAnchors = document.all.tags("meta");
var value1 = arrayOfAnchors[0].content;
document.getElementById('final').value= value1;
}
</script>
</head>
<body>
<form method="post" action="NewPhpWriteFile.php">
<input type="hidden" id = "final" name="sometext" value= "Hello Sir" >
<input type="submit" name = "submit" id="btnClick" value="Click Me" onclick="GetValue()"/>
</form>
</body>
</html>
这是NewPhpWriteFile.php
This is the NewPhpWriteFile.php
if (isset($_POST['sometext']))
{
$myFile = "testFile.txt";
$thetext=$_POST['sometext'];
writemyfile($myFile,$thetext,"w");
parent.focus();
} else
{
$thetext="Enter text here";
}
?>
当我执行文件并单击按钮"Click Me"时，仅将字符串"Hello Sir"传递到新文件"NewPhpWriteFile"，在将id"final"的值传递给新文件之前，不会对其进行更新php文件.
有人可以建议我出什么事了吗?还有其他方法吗?
When i execute the file, and click the button "Click Me", only the string "Hello Sir" is passed to the new file "NewPhpWriteFile", the value of id "final" is not getting updated before it is passed to the new php file.
Can some one suggest me whats going wrong? Is there any other way to do this?
推荐答案
_POST ['
_POST['sometext'])) {
myFile = " ;
myFile = "testFile.txt";
thetext =
thetext=
