我正在尝试将文本框值分配给php变量现在问题是我想要一个按钮来处理两个不同的页面,即如果我在文本框中输入' a'并点击按钮它应该重定向到' a.php'页面,如果我写在一个文本框' b'它应该重定向到'
;所以一个文本框,一个按钮两个不同的页面。
代码:
<html><head>
<meta charset="UTF-8" />
<script>
function submitForm(action)
{
document.getElementById('a').action = action;
document.getElementById('a').submit();
}
function submitForm1(action)
{
document.getElementById('b').action = action;
document.getElementById('b').submit();
}
</script>
</head>
<body >
<h3><font face="verdana" size="3"><b>Enter Text:</b></h3>
<input type="text" align="right" style="font-size:15pt;height:32px;"><br><br>
<form action="b.php" name="b" id="b" method="post">
<form action="a.php" name="a" id="a" method="post">
<input type="submit" onclick="submitForm('a.php')" value="TRY" name="a">
<input type="button" onclick="submitForm1('b.php')" value="TRY" name="b">
</form>
</form>
</body>
</html>

您可以根据输入内的文字更改onsubmit上的操作。
<html>
<head>
<script type="text/javascript">
function onsubmit_handler(){
var myForm = document.getElementById('myForm');
var data = document.getElementById('data').value;
if(data == "a")
myForm.setAttribute('action', 'a.php');
else if(data == "b")
myForm.setAttribute('action', 'b.php');
else
myForm.setAttribute('action', 'error.php');
}
</script>
</head>
<body>
<h3>Enter Text:</h3>
<form id="myForm" method="post" onsubmit="onsubmit_handler()">
<input type="text" id="data" name="data" value="">
<input type="submit" value="Post">
</form>
</body>
</html>

问题似乎是您正在使用getElementById,但输入元素没有ID(它们只有一个名称)。
我还建议将onSubmit事件附加到表单并从按钮中删除onClick事件。
编辑:在仔细查看代码之后,我发现其他一些问题可能会妨碍运营。最值得注意的是您无法嵌套表单标签。还有其他一些CSS和验证问题。
以下是一些有效的代码:
测试页面
function SubmitForm(el) {
// Get the form element so that we can set the action later
var form = document.getElementById('theForm');
// Set the action for the form based on which button was clicked
if (el.id == "A")
form.action = "a.php";
if (el.id == "B")
form.action = "b.php";
// You dont need to submit the form. It's alreasdy happening, so there is no need for an explicit call.
}
</script>
<h3 style="font-family: Verdana; font-weight: bold;">Enter Text:</h3>
<input type="text" style="font-size:15pt;height:32px;"><br><br>
<form method="post" onsubmit="SubmitForm();" action="fake.html" id="theForm">
<input type="submit" id="A" value="A" onclick="SubmitForm(this);">
<input type="submit" id="B" value="B" onclick="SubmitForm(this);">
</form>

使用此代码伙伴
<html><head>
<meta charset="UTF-8" />
<script>
function submitForm()
{
var link=document.getElementById('a');
var str1 = "a.php";
var n = str1.localeCompare(link);
if(n==1)
{
window.open("main.html");
}
else if(n==-1)
{
window.open("index.html");
}
}
</script>
</head>
<body >
<h3><font face="verdana" size="3"><b>Enter Text:</b></h3>
<input type="text" align="right" style="font-size:15pt;height:32px;"><br><br>
<input type="submit" onclick="submitForm()" value="TRY" name="a">
</form>
</form>
</body>
</html>
