Hi,
Hit an interesting problem today when trying to upload an image file < 2MB using dojo.io.iframe.
My function to
process the form is called, but before the form is posted to the server I am getting the following error:
TypeError: ifd.getElementsByTagName("textarea")[0] is undefined
My function that is used to action the post of the form is :
function uploadnewlogo(){
var logoDiv = dojo.byId('userlogo');
var logoMsg = dojo.byId('uploadmesg');
//prep the io frame to send logo data.
dojo.io.iframe.send({
url: "/users/profile/changelogo/",
method: "post",
handleAs: "text",
form: dojo.byId('logoUploadFrm'),
handle: function(data,ioArgs){
var response = dojo.fromJson(data);
if(response.status == 'success'){
//first clear the image
//dojo.style(logoDiv, "display", "none");
logoDiv.innerHTML = "";
//then we update the image
logoDiv.innerHTML = response.image;
}else if(response.status == 'error'){
logoMsg.innerHTML = data.mesg;
}else{
logoMsg.innerHTML = '<div class="error">Whoops! We can not
process your image.</div>';
}
},
error: function(data, ioArgs){
logoMsg.innerHTML = '<div class="error">' + data + '</div>';
}
});
}
The form is very basic with just a File input component and a simple button that calls this bit of javascript and dojo.
I've got very similar code in my application that uploads word/pdf documents and that doesn't error, but for some reason this does.
Any ideas or pointers on what I should try to get this to work without errors?
Oh I'm using php and Zend framework for the backend if that has anything to do with it, but I doubt it as it's not even hitting the server before it fails.
Many thanks,
Grant
