#StackBounty: #javascript #node.js #async.js #formidable Error handling with Node.js, Async and Formidable

Bounty: 200

In the following snippet I would like to validate the fields in the first async method.

If they are not valid I would like to return an error to the user immediately.

How do I do that?

var form = new formidable.IncomingForm();

    function (callback) {

        form.on('field', function (name, val) {
            // Get the fields

        form.on('fileBegin', function (name, file) {
            if (file.name !== "") {
                file.path = __dirname + '/upload/' + file.name;
    function (callback) {
        form.on('file', function (name, file) {
            try {
                // Do something with the file using the fields retrieved from first async method
            catch (err) {

], function (err) {
    //the upload failed, there is nothing we can do, send a 500

    if (err === "uploadFailed") {
        return res.send(500);

    if (err) {
        throw err;
    return res.status(200);

#StackBounty: #javascript #c# #jquery #asp.net #gridview How to bind GridView on TextBox's KeyPressed event

Bounty: 50

I have a TextBox with KeyPressed event and I want to bind GridView on that event.

<asp:TextBox ID="txtSearch" runat="server" OnKeyPressed="txtSearch_KeyPressed()">

  function txtSearch_KeyPressed()
      // gvBanquet is an ID of GridView and SearchBanquet method returns a DataTable
      gvBanquet.DataSource = DLBqt.SearchBanquet(txtSearch.Text.Trim());

Note that GridView binding code is from .CS file:

gvBanquet.DataSource = DLBqt.SearchBanquet(txtSearch.Text.Trim());

I don’t know how it will work? It should bind on key pressing of TextBox.

Edit: I have find a solution server site OnTextChanged event of TextBox which bind the GridView after pressing Enter instead of pressing a key.

<asp:TextBox ID="txtSearch" runat="server" OnTextChanged="txtSearch_TextChanged" 
    AutoPostBack="True" ></asp:TextBox>

protected void txtSearch_TextChanged(object sender, EventArgs e)
    gvBanquet.DataSource = DLBqt.SearchBanquet(txtSearch.Text.Trim());

I don’t want it with OnTextChanged event but I think it would work on keypressed event using JavaScript or jQuery so I don’t know how to do?

Update: I have tried below jQuery code to key pressed in textbox but its also not working.

$(document).ready(function () {

    $('#txtSearch').on("keyup", function () {
        // could bind bind GridView here??

Note: GridView and TextBox both are inside UpdatePanel.

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

</div> <!-- /.col-lg-12 -->
'> ' > '> '> '> '> '> '> '> '> Events ' />
<!-- /.col-lg-12 --> </ContentTemplate> </asp:UpdatePanel>

#StackBounty: #javascript #ios #iscroll iScroll on ios doesn't work after upgrading to iScroll5

Bounty: 100

I have a cordova app for ipad that uses iScroll to scroll among pages.
All worked fine until i upgraded to iScroll5.
I changed my code, to use new constructor and parameters, but it still doesn’t work. It simply doesn’t scroll.
I don’t know if i’m missing something obvious, but I cannot find an exaustive documentation about the upgrade.

This is an example of how I used it before (iScroll4):

var options = {hScroll:false, hScrollbar:false, snap:true, onScrollEnd: updatePages(), momentum: false};
var scroller = new iScroll("wrapper", options);  

And this is how I use it now (iScroll5):

var options = {scrollX: false, snap: true, momentum: false};  
var scroller = new IScroll("#wrapper", options);  
scroller.on("scrollEnd", updatePages());

Any help is greatly appreciated! Thanks!

#StackBounty: #javascript #jquery #html #ruby-on-rails #turbolinks Show page once FULLY loaded with Turbolinks

Bounty: 100

I am using Turbolinks and I have a loading animation that happens between pages. I am currently using page:load to complete the animation however, it seems as if page:load is acting like document ready rather than window.on load.

The desired effect is I have an overlay that is displayed over the content while the page is loading with a loading animation on top of it. Once the page is fully loaded (with images, objects, etc) it will then fade out the overlay to show the content.

What is happening is the content is being shown before the page is fully loaded. Here is the javascript I am using.

    (function () {

      function showPreloader() {

      function hidePreloader() {

      $(document).on('page:fetch', showPreloader);
      $(document).on('page:load', hidePreloader);
      $(window).on('load', hidePreloader);

#StackBounty: #javascript #html Cannot place cursor on whitespace-filled TEXTAREA from mobile

Bounty: 50

I have a TEXTAREA control (ID=”taCode”), maxlength=400, that is pre-filled with 400 whitespaces.

I use Javascript to force insert-mode (replace) when entering text into textarea:

var input = document.getElementById("taCode");
input.addEventListener('keypress', function(){
    var s = this.selectionStart;
    var e = this.selectionEnd;
    this.value = this.value.substr(0, s) + this.value.substr(e + 1);

    if (this.value.length < 399)
        this.value += new Array(399-this.value.length).join(' ');

    this.selectionEnd = this.selectionStart = s;
}, false);


<TEXTAREA ID="taCode" COLS="80" ROWS="5" MAXLENGTH="400" style="overflow:hidden">                                                                                                                                                                                                                                                                                                                                                                                                                </TEXTAREA>

Everything works fine using a desktop and mouse, but trying to place the cursor inside the TEXTAREA using a mobile (Iphone) fails (EDIT: Always placed at last pos on first row) and nothing can be typed into the field. Any idea of how to get it to work for mobiles?
