I dont know what does it mean.
Anyway, you cant upload more than 4mb is a server issue. Server doesn't allow more than 4mb. It is changeable.
To validate file: all you have to in onchnage action do your validation. if validation success then start uploading otherwise cancel selection by clearing the selected path
I wish I could believe there is an after life.

Hi,
In firefox, and chrome, I have a progress bar when someone uploads a file, however the same code doesn't work in IE (surprise surprise), it fails on:
var file = this.files[0];
My question is how do I do the equivalent for IE? Pointing me to the documentation would best.
code is:
function uploadImage(){
$('#percent').progressbar({
value: 0
});
$( "#dialog" ).dialog({
resizable: false,
height:150,
modal: true,
buttons: {
Cancel: function() {
if (xhr){
xhr.abort();
xhr = null;
}
$( this ).dialog( "close" );
}
}
});
document.getElementById('photo').addEventListener('change', function(e) {
var file = this.files[0];
var formdata = new FormData();
formdata.append('file', file);
xhr = new XMLHttpRequest();
xhr.file = file;
xhr.addEventListener('progress', function(e) {
var done = e.position || e.loaded, total = e.totalSize || e.total;
$('#percent').progressbar('value', (Math.floor(done/total*1000)/10));
}, false);
if ( xhr.upload ) {
xhr.upload.onprogress = function(e) {
var done = e.position || e.loaded, total = e.totalSize || e.total;
$('#percent').progressbar('value', (Math.floor(done/total*1000)/10));
};
}
xhr.onreadystatechange = function(e) {
if ( 4 == this.readyState ) {
console.log(this);
$('#src').val(this.responseText);
$('#dialog').dialog('close');
xhr = null;
}
};
xhr.open('post', '/index/fileupload', true);
xhr.send(formdata);
}, false);
}

Hi,
came acoss this bit of code & don't fully understand it:
Value <<= 1
as in if((Value <<= 1) <= 255).......
I know << is equivalent to XOR but does this mean:
Value = Value << 1
if(Value <= 255)...
or something else???
Also:
value1 ^= value2....
is this equivalent to:
value1 = value1 ^ value2
Some of these short cuts get me and do you think I can find out about <<=...try googling that.
Any help appreciated
|
|
|
|
|
<< means bitshift left
>> is bitshift right
^ is XOR.
and a <operator>= b is the same as:
a = a <operator> b

You've used jQuery.noConflict() and then tried to access jQuery using the $() function. If you use noConflict, you have to use the full jQuery() function instead of $() - see here for details: http://api.jquery.com/jQuery.noConflict/[^]

Tried TypeScript? I've been playing around with it for a few days and I'm not sure what I think of it. It's almost javascript, but you get some benefits by using types and maybe a easier syntax.
I installed Mads Kristensen's Web Essentials 1.3 and of course the official plug-in for Visual Studio
Web Essentials crashes from time to time, but Mads is working on it 
Do you have any experiences using TypeScript? Maybe some examples to share? How do you solve using libraries like jQuery(ui), knockout, underscore etc? It's really boring to write all these typescript interfaces. Typescripts homepage should have a directory for interfaces for the most used js-libraries (or maybe such directory exists somewhere?)

Had installed this plugin and must say that it is tragically slow for me.
Now it is disabled and i don't think I will ever enable this again since it don't add anything useful.
And for type script? I really don't understand why people want to do C from JS. It is dynamic language. Type checking is fun
and make thinks little easier. But JS is for DOM manipulation and client events. Nothing serious really.
I had written bigger library with JS for WebGL, and I must say that this language is not for that kind of work. Now trends for doing rich, complicated web apps is good, but in my opinion we trying to force JS to do work it not suppose to. I think we need better language for this, and experiments coffe script, and type script is half step into good direction. If you have know JS anyway it isn't a solution.

Yes. we ask that you post your question ONCE. Crossposting like this only annoys those who might otherwise help you.

Does any of the message you posted have a purpose?

One approach is to provide a message that the form has been submitted, and then provide some means to prevent the web page reader from submitting the form again. In its simplest variation, the following would work:
function validateSubmission(evt) {
...
alert("Thank you, we're processing your order right now");
document.getElementById("submitbutton").disabled=true; // disable
Multiple concurrent form submissions are one of the worst problems that can occur in a user interface. Most people would be unhappy if, say, they found they had purchased two of the same item when they were only expecting to purchase one.
There are several different approaches you can take to prevent duplicate form submissions, and how strict you want to be depends on the seriousness of the double submission.

It really depends on what you are doing. There are a lot of UI test suites out there.
I personally do a lot of jQuery development and find that the qUnit framework works great. You could give that a go.

I have been working on a project that requires me to create a vertical auto-hide toolbar that appears on the right side of the webpage. I am not even sure if that is possible using javascript as I am quite new to javascript.
|
|
|
|
|
If you question is if it is possible in Javascript?
My Answer is yes quite possible. As a matter of fact you just gave me the idea. I will implement this for my in house application today.
For your help:

2. OnMouseOver action
3. OnMouseOut action

I thinking about posting some code to help out, but every circumstance if different. It's actually a combo of jquery and javascript, and i'm afraid you won't understand it.
It takes a panel you create in asp.net at left -360px with the id of "_ib_ProductEditor_Toolbox_Next", create a event bind in the dom for click, loads up dynamic html for a progress wheel, and then loads data, parts list, and fly's out to the right using animation. Requires Jquery 1.6 something. it makes a close link in the upper right, and create another bind, to animate the close back to -360px.
It should give you and idea of how to start yours at least.
$(document).ready(function () {
$('[id*="_ib_ProductEditor_Toolbox_Next"]').click(function () {
toolbox_ProductItem_Next_MouseOver();
return false;
});

Oh men! Why your simple auto-hide panel is so complicated? 2 css classes and maybe one ajax for dynamic loading of content should be enough!
