Ajax Form Submit - ajax

the form is submiting as normal request instead of Ajax.
$(document).ready(function () {
StatusComments();
});
function StatusComments() {
$('.comment').submit(function () {
$(this).ajaxSubmit(options);
return false;
});
var options = {
beforeSubmit: showRequest,
success: showResponse,
resetForm: true
};
function showRequest(formData, jqForm, options) {
var textbox = $('#StatusMessageReplyMessage').val();
alert(textbox);
}
function showResponse(responseText, statusText, xhr, $form) {
}
}
i have a similar one for Status update like this
function StatusUpdates() {
$('#updateStatus').submit(function () {
$(this).ajaxSubmit(options);
return false; // prevent a new request
});
var options = {
target: '.user-status',
// target element(s) to be updated with server response
beforeSubmit: showRequest,
// pre-submit callback
success: showResponse,
// post-submit callback
// other available options:
//url: url // override for form's 'action' attribute
//type: type // 'get' or 'post', override for form's 'method' attribute
//dataType: null // 'xml', 'script', or 'json' (expected server response type)
//clearForm: true // clear all form fields after successful submit
resetForm: true // reset the form after successful submit
// $.ajax options can be used here too, for example:
//timeout: 3000
};
function showRequest(formData, jqForm, options) {
var textbox = $('#StatusMessageMessage').val();
if ((textbox == '') || (textbox == "What have you been eating ?")) {
alert('Please Enter Something and click submit.');
return false;
} else {
$('#StatusMessageMessage').attr('disabled', true);
}
}
function showResponse(responseText, statusText, xhr, $form) {
$('#StatusMessageMessage').attr('disabled', false);
$('.share').slideUp("fast");
$('#StatusMessageMessage').animate({
"height": "18px"
}, "fast");
}
}

Instead of
$('.comment').submit(function () {
$(this).ajaxSubmit(options);
return false;
});
Try
$('.comment').click(function(e) {
e.preventDefault();
$(this).ajaxSubmit(options);
return false;
});

chrome popup extension not sending data on the api.php file

I am using chrome popup extension but no data is sent to the php file named api.php.I have searched on stackoverflow and found ajax related content but nothing is working.here is my popover.js file which uses ajax.I used $_POST['data'] to grab the data in api.php file
var api_url = "https://localhost/psol/api.php";
window.onload = function () {
$("#checkout_btn").click(function () {
chrome.runtime.sendMessage({
'btnClicked': true
}, function () {});
});
chrome.runtime.onMessage.addListener(
function (request, sender, sendResponse) {
console.log(request);
if (request.message === "show-loading") {
$(".psol-button").addClass('hide');
$(".psol-loader").removeClass("hide");
}
if (request.message === "hide-loading") {
$(".psol-button").removeClass('hide');
$(".psol-loader").addClass("hide");
}
if (request.message === "post-cart") {
console.log(request.data);
alert(JSON.stringify(request.data));
chrome.runtime.sendMessage({
'postCartDone': true,
'redirectTo': api_url
}, function () {});
$.ajax({
url: api_url,
type: "POST",
data: request.data,
// data:{name:'uzair'},
success: function (result) {
// alert("all done");
console.log(1, result);
}
}).done(function (result) {
console.log(2, result);
if (result.cartCount === 0) {
alert('There are no items in cart to checkout');
}else {
alert("this is also redirect");
}
});
}
});
};

How can I handle a ajax request response in the Flux Architecture?

Looking at the Flux Documentation I can't figure out how the code to a ajax update, and a ajax fetch would fit into the dispatcher, store, component architecture.
Can anyone provide a simple, dummy example, of how an entity of data would be fetched from the server AFTER page load, and how this entity would be pushed to the server at a later date. How would the "complete" or "error" status of request be translated and treated by the views/components? How would a store wait for the ajax request to wait? :-?
Is this what you are looking for?
http://facebook.github.io/react/tips/initial-ajax.html
you can also implement a fetch in the store in order to manage the information.
Here is an example (it is a concept, not actually working code):
'use strict';
var React = require('react');
var Constants = require('constants');
var merge = require('react/lib/merge'); //This must be replaced for assign
var EventEmitter = require('events').EventEmitter;
var Dispatcher = require('dispatcher');
var CHANGE_EVENT = "change";
var data = {};
var message = "";
function _fetch () {
message = "Fetching data";
$.ajax({
type: 'GET',
url: 'Url',
contentType: 'application/json',
success: function(data){
message = "";
MyStore.emitChange();
},
error: function(error){
message = error;
MyStore.emitChange();
}
});
};
function _post (myData) {
//Make post
$.ajax({
type: 'POST',
url: 'Url',
// post payload:
data: JSON.stringify(myData),
contentType: 'application/json',
success: function(data){
message = "";
MyStore.emitChange();
},
error: function(error){
message = "update failed";
MyStore.emitChange();
}
});
};
var MyStore = merge(EventEmitter.prototype, {
emitChange: function () {
this.emit(CHANGE_EVENT);
},
addChangeListener: function (callback) {
this.on(CHANGE_EVENT, callback);
},
removeChangeListener: function (callback) {
this.removeListener(CHANGE_EVENT, callback);
},
getData: function (){
if(!data){
_fetch();
}
return data;
},
getMessage: function (){
return message;
},
dispatcherIndex: Dispatcher.register( function(payload) {
var action = payload.action; // this is our action from handleViewAction
switch(action.actionType){
case Constants.UPDATE:
message = "updating...";
_post(payload.action.data);
break;
}
MyStore.emitChange();
return true;
})
});
module.exports = MyStore;
Then you need to subscribe your component to the store change events
var React = require('react');
var MyStore = require('my-store');
function getComments (){
return {
message: null,
data: MyStore.getData()
}
};
var AlbumComments = module.exports = React.createClass({
getInitialState: function() {
return getData();
},
componentWillMount: function(){
MyStore.addChangeListener(this._onChange);
},
componentWillUnmount: function(){
MyStore.removeChangeListener(this._onChange);
},
_onChange: function(){
var msg = MyStore.getMessage();
if (!message){
this.setState(getData());
} else {
this.setState({
message: msg,
data: null
});
}
},
render: function() {
console.log('render');
return (
<div>
{ this.state.message }
{this.state.data.map(function(item){
return <div>{ item }</div>
})}
</div>
);
}
});
I hope it is clear enough.

Routing through AJAX

I have an ajax request handling validation of form fields (login+signup+forget password). In its success scenario, I want it to route to another page, but when I use Redirect::route('name'); as return from controller, it completes the request with 200 and generates another GET request which just returns the html as response and does not route to other page.
AJAX
$('form[data-remote]').on('submit', function (e) {
var form = $(this);
var method = form.find('input[name="_method"]').val() || 'POST';
var url = form.prop('action');
$.ajax({
type: method,
url: url,
data: form.serialize(),
beforeSend: function () {
$('#ajax-loading').show();
$(".has-error").text("");
$('#login-error').addClass('display-hide');
$('#forget-user-error').addClass('display-hide');
}
})
.done(function (data) {
if (data.signup_fail) {
$.each(data.errors, function (index, value) {
var errorSpan = '#' + index + '_error';
$(errorSpan).removeClass('hidden');
$(errorSpan).empty().append(value);
});
$('#successMessage').empty();
}
else if (data.email_fail) {
$('#email_error').text('This Email already in use against an account.');
}
else if (data.company_fail) {
$('#email-error-popup').trigger('click');
}
else if (data.login_fail) {
$('#login-error').removeClass('display-hide');
}
else if (data.forget_fail) {
$.each(data.errors, function (index, value) {
var errorSpan = '#' + index + '_error';
$(errorSpan).empty().append(value);
});
$('#successMessage').empty();
}
else if (data.forget_user_fail) {
$('#forget-user-error').removeClass('display-hide');
}
else if (data.reset_fail) {
$.each(data.errors, function (index, value) {
var errorSpan = '#' + index + '_error';
$(errorSpan).removeClass('hidden');
$(errorSpan).empty().append(value);
});
$('#successMessage').empty();
}
})
.fail(function (jqXHR, ajaxOptions, thrownError) {
alert('No response from server');
});
return false;
});
How can I route to the other page on success condition? The ajax is triggered on a form submit button.
As you are doing an ajax request you can't just redirect from the controller on successful validation. Instead, just return the url you want to redirect to, as response to the ajax request similar to the way you are returning the validation errors. And in your js file use that url to redirect to new page.
#your above code
else if (data.forget_user_fail) {
$('#forget-user-error').removeClass('display-hide');
}
else if (data.reset_fail) {
$.each(data.errors, function (index, value) {
var errorSpan = '#' + index + '_error';
$(errorSpan).removeClass('hidden');
$(errorSpan).empty().append(value);
});
$('#successMessage').empty();
}
else{
window.location.replace(data.redirect_url); //this will redirect to new page
}
})
.fail(function (jqXHR, ajaxOptions, thrownError) {
alert('No response from server');
});
return false;
});

Opposite of PreventDefault() : Continuing ActionLink logic

<%: Html.ActionLink("Print", "Print", "Print", New With {.id = Model.ID}, New With {.target = "_blank", .class = "print"})%>
How to return to my actionlink's functionality once preventDefault is called? ( the _blank page is not being opened on return)
$('#NameOfButton').bind('click', function (e) {
e.preventDefault(); // Stop click event
//Gather Data
var data = $(this).parents('form').first().serialize();
//Check Data , if saved to DB continue Click functionality
$.ajax({
url: '<%:Url.Action("Get")%>',
cache: false,
type: 'POST',
data: data,
success: function (result) {
if (result.Success == true) {
//return;
return true;
} else {
//do nothing
console.log('false');
}
}
});
});
Solution:
$('#NameOfButton').bind('click', function (e) {
e.preventDefault(); // Stop click event
//Gather Data
var el= $(this);
var data = $(this).parents('form').first().serialize();
//Check Data , if saved to DB continue Click functionality
$.ajax({
url: '<%:Url.Action("Get")%>',
cache: false,
type: 'POST',
data: data,
success: function (result) {
if (result.Success == true) {
window.location.href = el.attr('href');
} else {
//do nothing
}
}
});
});
You can trigger the event again:
$('#NameOfButton').bind('click', function (e, skip) {
if (skip) return; // check param
e.preventDefault(); // Stop click event
//Gather Data
var data = $(this).parents('form').first().serialize();
var el = $(this);
//Check Data , if saved to DB continue Click functionality
$.ajax({
url: '<%:Url.Action("Get")%>',
cache: false,
type: 'POST',
data: data,
success: function (result) {
if (result.Success == true) {
console.log('true');
el.trigger('click', [true]); // trigger same event with additional param
} else {
//do nothing
console.log('false');
}
}
});
});

jQuery dialog for a partial view is not opening modal

I have built a jquery dialog to show a partial view for entering data.
I have built the action link:
#Html.ActionLink("Add New Service Provider", "PartialNewCust", "Customer", null, new { #class = "addServiceProviderLink" })
I have the controller action:
public ActionResult PartialNewCust()
{
return PartialView();
}
And the div / jQuery code:
<div id="AddServiceProvDialog" title="Add Service Provider"></div>
<script type="text/javascript">
var linkObj;
$(function () {
$(".addServiceProviderLink").button();
$('#AddServiceProvDialog').dialog(
{
autoOpen: false,
width: 400,
resizable: false,
modal: true,
buttons:
{
"Add": function () {
$("#addProviderForm").submit();
},
"Cancel": function () {
$(this).dialog("close");
}
}
});
$(".addServiceProviderLink").click(function () {
linkObj = $(this);
var dialogDiv = $('#AddServiceProvDialog');
var viewUrl = linkObj.attr('href');
$.get(viewUrl, function (data) {
dialogDiv.html(data);
//validation
var $form = $("#addProviderForm");
// Unbind existing validation
$form.unbind();
$form.data("validator", null);
// Check document for changes
$.validator.unobtrusive.parse(document);
// Re add validation with changes
$form.validate($form.data("unobtrusiveValidation").options);
//open dialog
dialogDiv.dialog('open');
return false;
});
});
});
The partial view renders fine but opens a new page and does not come up as a modal dialog.
What am I doing wrong.
On a side note: my autocomplete code is also not working by my jQuery datetime picker is...
$(document).ready(function()
{
$(".date").datepicker();
}
);
$(document).ready(function () {
$("#CustByName").autocomplete(
{
source: function (request, response) {
$.ajax(
{
url: "/Cases/FindByName", type: "GET", dataType: "json",
data: { searchText: request.term, maxResults: 10 },
contentType: "application/json; charset=utf-8",
success: function (data) {
response($.map(data, function (item) {
return {
label: item.CustomerName,
value: item.CustomerName,
id: item.CustomerID
}
})
);
}
});
},
minLength: 3
});
});
My guess is that you misplaced the return false statement in the button's click handler, thus the default behavior is not prevented as you expect, and the link is simply followed:
$(".addServiceProviderLink").click(function () {
...
$.get(viewUrl, function (data) {
dialogDiv.html(data);
...
dialogDiv.dialog('open');
// this return statement should be in the "click" handler,
// not in success callback of the .get() method !
return false;
});
});
Your code should then be:
$(".addServiceProviderLink").click(function () {
...
$.get(viewUrl, function (data) {
...
});
// return here to prevent default click behavior
return false;
});
