how can get response from <form target="IFrame">
There is a simple web page which sends request, handles & manipulated by a servlet class and send back the response text.while i want ajax type handleing the request at client side that is why i am giving the response target to a invsible iframe. *but i want to print success on the page after iframe gets the response *
<html> <body>
<form action="test" method="post" target="IFrame"> /*response target is iframe*/
<input type="text" name="logic" />
<input type="submit" value="Submit" />
</form>
<iframe name="IFrame" style="width:0; height:0">开发者_运维百科 </iframe>
</body> </html>
i think this can be done using javascript or jquery, please guid me if you have any idea.
In the page which loads in the iframe, you will need to invoke a parent function.
<!-- This is the Parent. Call it JSTest1.html -->
<html>
<head>
</head>
<body>
<script type="text/javascript">
function parentAlert() {
alert('hey there from the parent');
}
</script>
I'm the parent
<iframe src="/JSTest2.html"></iframe>
</body>
<!-- this is the iframe html loaded. Call it JSTest2.html-->
<html>
<head>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
</head>
<body>
<script type="text/javascript">
$(document).ready( function() {
window.parent.parentAlert();
});
</script>
In the Iframe.
</body>
To send a message from Iframe to Parent window page:
<script type="text/javascript">
$(document).ready( function() {
//Message part is two parts Event name and Data you want to send
// Example message = "my_action,my_data"
message = "my_action,my_data"
parent.postMessage(message, "*");
});
</script>
At the parent window you can do the following to listen to this message and capture it:
var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
var eventer = window[eventMethod];
var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";
eventer(messageEvent,function(e) {
// Youe message which you send is captured here in e.data will split it on ',' to get the event and the data
message = e.data.split(',')[0]
value = e.data.split(',')[1]
if ( message === "my_action" ) {
myParentFunction(value)
}
},false);
