I want to change form attributes with JQuery. In other browsers it works fine, but not in IE(6,7,8).
Code:
action = '/controller/action/id/';
target = 'upload_iframe';
enctype = 'multipart/form-data';
$('#form1').attr("action",action);
$('#form1').attr("target",target);
$('#form1').attr("enctype",enctype);
So what's the problem ? Your help would be appreciated.
Try this
$('#form1').attr("action","/controller/action/id/");
$('#form1').attr("target","upload_iframe");
$('#form1').attr("enctype","multipart/form-data");
I just tried this and it works in every browser for me ..
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script src="http://code.jquery.com/jquery-1.4.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#btn").click(function() {
$('#form1').attr("action","/controller/action/id/");
$('#form1').attr("target","upload_iframe");
$('#form1').attr("enctype","multipart/form-data");
});
});
</script>
</head>
<body>
<form id="form1" action="something.html" method="post" name="forma" target="target" enctype="nope">
<a href="#" id="btn">Uno mas</a>
</form>
</body>
</html>
It works this way for me as well, just tested IE7 & 8 :
action = '/controller/action/id/';
target = 'upload_iframe';
enctype = 'multipart/form-data';
$('#form1').attr("action",action);
$('#form1').attr("target",target);
$('#form1').attr("enctype",enctype);
console.log($('#form1').attr("action") + " " + $('#form1').attr("target") + " " + $('#form1').attr("enctype"));
alert($('#form1').attr("action") + " " + $('#form1').attr("target") + " " + $('#form1').attr("enctype"));
You might have a field named "action":
<input name="action" value="hot">
And IE, being retarted browser that it is, mixes the 2 up...
Managed to get the enctype attribute working across browsers (FF, IE7/IE8, Chrome) through the following hack (using the encoding property):
$('#form1').get(0).encoding = 'multipart/form-data';
It seems, jQuery attr() method doesn't work in IE8 for enctype attribute. For example:
f=$('<form>');
f.attr({"target":"ta","id":"idx"});//OK - FF and IE8
f.attr("method","post");//OK - FF and IE8
f.attr("enctype","multipart/form-data");//OK in FF, but not in IE8!!!
IE8 doesn't send file content through upload. But there is easy solution:
f=$('<form enctype="multipart/form-data" />');//FF and IE8

f=$('<form />');

//comment two previous lines, uncomment next line and it work in IE8
//f=$('<form enctype="multipart/form-data" />');
f.attr("method","post");
f.append('<input type="file" name="ffile" id="ffile" /><input name="fsubmit" id="fsubmit" type="submit">');
