I'm trying to debug an issue that I'm only having in IE8. It works fine in IE 9+, and chrome. I'm using Aspera
to select a file, and am calling a custom function on a callback. the function is as follows;
function uploadPathsRecieved(pathsArray) {
var file_path_selector = '#file_path';
...
$(file_path_selector).text(''); // (*)
...
}
On the (*) line, I get an error that file_path_selector
is undefined. This didn't make much sense to me, so after some playing around to get a feel for the problem, I wound up with the following code:
function uploadPathsRecieved(pathsArray) {
var x = 3;
var y = 4;
var z = x + y;
z += 2;
$('#file_path').text(''); // (*)
...
}
When I run the program with this code, I still get the error "file_path_selector is undefined"
at the (*) line. I'm out of ideas on what the next steps I should take to try and hunt down this problem are.
My gut feeling tells me that there's something being cached, but if I move the (*) line around, the error follows it, and the script window reflects the changes that I make to it.
Here's the Aspera code that's calling my function:
function wrapCallbacks(callbacks) {
return wrapCallback(function() {
var args, i;
try {
args = Array.prototype.slice.call(arguments);
for ( i = 0; i < args.length; i++) {
if (isObjectAndNotNull(args[i]) && isDefined(args[i].error)) {
// error found
if (isDefined(callbacks.error)) {
callbacks.error.apply(null, args);
}
return;
}
}
// success
if (isDefined(callbacks.success)) {
callbacks.success.apply(null, args);
}
} catch (e) {
AW.utils.console.error(e.name + ": " + e.message);
AW.utils.console.trace();
}
});
}
And here's the entirety of my function, as it exists right now:
var uploadPathsRecieved = function uploadPathsRecieved(pathsArray) {
//var file_path_selector = '#file_path';
var x = 3;
var y = 4;
var z = x + y;
z += 2;
$('#file_path').text('');
var button_selector = '#select_aspera_file';
var textbox_selector = '.aspera_textbox';
/*if (uploadPathsRecieved.fileSelecting == 'cc_file') {
file_path_selector = '#cc_file_path';
button_selector = '#select_cc_file';
textbox_selector = '.cc_aspera_textbox';
} else if (uploadPathsRecieved.fileSelecting == 'preview_file') {
file_path_selector = '#preview_file_path';
button_selector = '#select_preview_file';
textbox_selector = '.preview_aspera_textbox';
}*/
App.AsperaUploadPaths = [];
if (pathsArray.length == 1) {
$(button_selector).text("Clear File");
App.AsperaUploadPaths = pathsArray;
var error_message = pathsArray[0];
$(button_selector).parent().children(textbox_selector).text(error_message).removeClass('error');
//$(file_path_selector).attr('value', pathsArray[0]);
}
else
{
var error_message = 'Please select a single file';
$(button_selector).parent().children(textbox_selector).text(error_message).addClass('error');
}
}
Solved it. file_path was an <input>
, and IE 8 and below doesn't allow you to add text or html to inputs. I fixed it by changing $(file_path_selector).text('');
to $(file_path_selector).attr('value', '');
