i'm making an app to track different craft beers i've tasted. part of that is making an AJAX call to set a cookie in the uder's browser -- i'm json_encoding the list.beerList array and trying to store it in a cookie. for some reason, the cookie is getting set, but Firebug isn't registering an AJAX call being made. and even when i send something back, the success condition of the jquery AJAX function isn't firing. code below:
angular.module( 'beerList', [] ).controller( 'beerListController', function($scope) {
var list = this;
list.beerList = [];
angular.element(document).ready( function() {
list.getCookie();
})
list.addBeer = function() {
var beerEntered = $( '#beer' ).val();
var breweryEntered = $( '#brewery' ).val();
var abvEntered = $( '#abv' ).val();
var notesEntered = $( '#notes' ).val();
list.beerList.push( { beer: beerEntered, brewery: breweryEntered, abv: abvEntered, notes: notesEntered } );
list.setCookie();
}
list.setCookie = function() {
var string = JSON.stringify(list.beerList);
$.ajax({
url: 'ABSOLUTE/PATH/TO/setCookie.php',
dataType: 'jsonp',
data: {
string: string
},
success: function(data) {
alert('success!');
}
})
}
list.getCookie = function() {}
})
thanks so much for your help!

I am trying to make a facebook and twitter style mention system using jquery ajax php but i have a problem if i try to #mention more then one user. For example if i start to type something like the follow:
Hi #stack how are you.
The results showing #stack but if i try to mention another user like this:
Hi #stack how are you. i am #azzo
Then the results are nothing. What i am missing my ajax code anyone can help me please ?
I think there is a regex problem for search user_name. When i write some username after first one like #stack then the ajax request posting this:
f : smen
menFriend : #stack
posti : 102
But if i want to tag my other friend in the same text like this:
Hi #stack how are you. I am #a then ajax request looks like this:
f : smen
menFriend : #stack, #a
posti : 102
So what I'm saying is that apparently, ajax interrogates all the words that begin with #. It needs to do is interrogate the last #mention from database.
var timer = null;
var tagstart = /#/gi;
var tagword = /#(\w+)/gi;
$("body").delegate(".addComment", "keyup", function(e) {
var value = e.target.value;
var ID = e.target.id;
clearTimeout(timer);
timer = setTimeout(function() {
var contents = value;
var goWord = contents.match(tagstart);
var goname = contents.match(tagword);
var type = 'smen';
var data = 'f=' +type+ '&menFriend=' +goname +'&posti='+ID;
if (goWord.length > 0) {
if (goname.length > 0) {
$.ajax({
type: "POST",
url: requestUrl + "searchuser",
data: data,
cache: false,
beforeSend: function() {
// Do Something
},
success: function(response) {
if(response){
$(".menlist"+ID).show().html(response);
}else{
$(".menlist"+ID).hide().empty();
}
}
});
}
}
}, 500);
});
Also here is a php section for searching user from database:
$searchmUser = mysqli_real_escape_string($this->db,$searchmUser);
$searchmUser=str_replace("#","",$searchmUser);
$searchmUser=str_replace(" ","%",$searchmUser);
$sql_res=mysqli_query($this->db,"SELECT
user_name, user_id
FROM users WHERE
(user_name like '%$searchmUser%'
or user_fullname like '%$searchmUser%') ORDER BY user_id LIMIT 5") or die(mysqli_error($this->db));
while($row=mysqli_fetch_array($sql_res,MYSQLI_ASSOC)) {
// Store the result into array
$data[]=$row;
}
if(!empty($data)) {
// Store the result into array
return $data;
}
Looks like you're sending an array which is result of match you in AJAX request.
Though I cannot test it but you can use a lookahead in your regex and use 1st element from resulting array. Negative lookahead (?!.*#\w) is used to make sure we match last element only.
var timer = null;
var tagword = /#(\w+)(?!.*#\w)/;
$("body").delegate(".addComment", "keyup", function(e) {
var value = e.target.value;
var ID = e.target.id;
clearTimeout(timer);
timer = setTimeout(function() {
var contents = value;
var type = 'smen';
var goname = contents.match(tagword);
if (goname != undefined) {
var data = 'f=' +type+ '&menFriend=' +goname[1] +'&posti='+ID;
$.ajax({
type: "POST",
url: requestUrl + "searchuser",
data: data,
cache: false,
beforeSend: function() {
// Do Something
},
success: function(response) {
if(response){
$(".menlist"+ID).show().html(response);
} else {
$(".menlist"+ID).hide().empty();
}
}
});
}
}, 500);
});
On a page I have a list of dates which I want to edit via AJAX.
Example:
<li>January 2015<a data-update_url="/frame_date/22/update/" class="update" id="update_framedate_22" href="javascript:void(0)">Edit</a>
When the user clicks on the Edit link, I catch element id and the edit link.
Than AJAX requests the update form from the server. And now I have to place the form instead of the element with the mentioned id.
In other words, in frame_date_update_show_get I need element's id. In the example below, I keep it in the global variable date_id. But inside me there is a protest: I was always taught that global variables is a bad practice. But in this case I don't know how to get along without the global variable date_id.
Could you give me some piece of advice: is my code acceptable or there is a better way to cope with the problem.
function frame_date_update_show_get(data){
$("#" + date_id).replaceWith(data);
}
function frame_date_update_get_data(){
date_id = this.getAttribute('id')
var cuaghtUrl = this.getAttribute('data-update_url');
$.ajax({
method: 'get',
url: cuaghtUrl,
success: frame_date_update_show_get,
error: fail
});
}
var date_id = ""
Use an anonymous function as success callback function and then call frame_date_update_show_get with an additional date_id parameter:
function frame_date_update_show_get(data, date_id) {
$("#" + date_id).replaceWith(data);
}
function frame_date_update_get_data() {
var date_id = this.getAttribute('id')
var cuaghtUrl = this.getAttribute('data-update_url');
$.ajax({
method: 'get',
url: cuaghtUrl,
success: function(data) {
frame_date_update_show_get(data, date_id);
},
error: fail
});
}
I would use contenteditable combined with AJAX this way:
function dateChange(options){
switch( options.action ) {
case 'update':
if( options.id && options.text && options.updateUrl ) {
$.ajax({
method: 'post',
url: options.updateUrl,
data: {
id: options.id,
html: options.text
},
success: function(response) {
options.element.html( response );
options.element.removeClass('editing');
},
error: function(err) {
console.log( 'request failed: ' + err.text );
}
});
};
break;
default:
console.log( 'action invalid' );
return false;
break;
};
};
var editTimeout = null;
$('li[data-update-url]').on('input', function(e) {
var thisText = $(this);
thisText.addClass('editing');
clearTimeout( editTimeout );
editTimeout = setTimeout(function() {
var updateUrl = thisText.data('updateUrl');
var id = thisText.data('id');
dateChange({
'action': 'update',
'element': thisText,
'id': id,
'updateUrl': updateUrl,
'text': thisText.html()
});
}, 1000);
});
.editing {
color: orange;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li data-update-url="/echo/html/" data-id="update_framedate_22" contenteditable>January 2015</li>
</ul>
Check how it works on JSFiddle.
This code would be easy to expand for other actions you may need, as delete, add.
I have this scenario where when submiting html form we call javascript method to validate the form. Problem is that validation is done through Ajax request calling php function which returns json array which is empty or contains array with errors.
I am using Ajax request as this newValidation function will be used on all forms on my application so all field ids names and stuff is dynamic same as validation messages.
Console log results are:
Undifiend
It should be True or False.
So it looks like .done run after console.log.
I thought .done is waiting until ajax is finished and only then proceed?
Reason why I am asking I need this .done to run first so it can assing answer variable and only then return boolean to the form. Does this even possible?
UPDATED:
Html form:
<form id="systemManagementSettings" action="#" method="POST" onsubmit="return newValidation('systemManagementSettings')">
JavaScript
function newValidation(formId){
var answer;
var $inputs = $('#'+formId+' :input');
var values = {};
$inputs.each(function() {
values[this.id] = $(this).val();
$( "div#"+this.id+"_validation" ).text("");
});
var FinalValidation = $.ajax({
url: "validation/getValidationData",
type: "POST",
data: {form: formId, values: values},
});
FinalValidation.done(function(data){
var resultArray = JSON.parse(data);
if($.isEmptyObject(resultArray))
{
answer = true;
}
else
{
$.each( resultArray, function( key, value ) {
$( "div#"+key+"_validation" ).text(value);
});
answer = false;
}
});
console.log(answer);
return answer;
}
How do you prevent the form from actually being submitted?
Use event.preventDefault().
UPDATE
Submit the form in the done function.
function newValidation(formId){
var answer;
var $inputs = $('#'+formId+' :input');
var values = {};
$inputs.each(function() {
values[this.id] = $(this).val();
$( "div#"+this.id+"_validation" ).text("");
});
var FinalValidation = $.ajax({
url: "validation/getValidationData",
type: "POST",
data: {form: formId, values: values},
});
FinalValidation.done(function(data){
var resultArray = JSON.parse(data);
if($.isEmptyObject(resultArray))
{
$.ajax({
url: $('#'+formId).attr('action'),
type: "POST",
data: {form: $('#'+formId).serializeArray()},
});
}
else
{
$.each( resultArray, function( key, value ) {
$( "div#"+key+"_validation" ).text(value);
});
}
});
return false; //all the time
}
I am adding a LoadMore function to append more posts based on the length of current displayed posts and total posts in DOM. The issue I am having is when I console log the listofposts and I inspect the element in Google Chrome, I see the length is showing zero (0). I am not sure exactly where I have gone wrong or if the aproach I have taken is right or should I separate the two functions by first loading the first 4 posts, then create a new function separate to handle the appending?
$(document).on('pagebeforeshow', '#blogposts', function() {
//$.mobile.showPageLoadingMsg();
$.ajax({
url: "http://howtodeployit.com/category/daily-devotion/?json=recentstories&callback=",
dataType: "json",
jsonpCallback: 'successCallback',
async: true,
beforeSend: function() { $.mobile.showPageLoadingMsg(true); },
complete: function() { $.mobile.hidePageLoadingMsg(); },
success:function(data){
var $listofposts = $('data');
console.log($listofposts);
var $loadMore = $listofposts.parent().find('.load-more');
// console.log($loadMore);
currentPage = 0;
postsPerPage = 4;
var showMorePosts = function () {
$offset = currentPage * postsPerPage, //initial value is 0
posts = data.posts.slice($offset, $offset + postsPerPage);
console.log(posts);
$.each(posts, function(i, val) {
//console.log(val);
$("#postlist").html();
var result = $('<li/>').append([$("<h3>", {html: val.title}),$("<p>", {html: val.excerpt})]).wrapInner('');
$('#postlist').append(result);
console.log(result);
});
if(posts.length !== postsPerPage){
alert ('True');
$loadMore.hide();
}
currentPage++;
$("#postlist").listview();
$("#postlist").listview('refresh');
}
showMorePosts();
$loadMore.on('click', showMorePosts);
}});
var $listofposts = $('data');
is asking jQuery for a list of all <data> tags in the document.
You might want to use $(data) instead.
I have constructed an app with push state. Everything is working fine. However in some instances my jquery function are fireing multiple times. That is because when I call push state I bind the particular js file for each page I call. Which means that the same js functions are binded many times to the html while I surf in my page.
Tip: I am using documen.on in my jquery funciton because I need my function to get bound to the dynamical printed HTML through Ajax.
I tried to use off in the push state before printing with no success!
Here is my code:
var requests = [];
function replacePage(url) {
var loading = '<div class="push-load"></div>'
$('.content').fadeOut(200);
$('.container').append(loading);
$.each( requests, function( i, v ){
v.abort();
});
requests.push( $.ajax({
type: "GET",
url: url,
dataType: "html",
success: function(data){
var dom = $(data);
//var title = dom.filter('title').text();
var html = dom.find('.content').html();
//alert(html);
//alert("OK");
//$('title').text(title);
$('a').off();
$('.push-load').remove();
$('.content').html(html).fadeIn(200);
//console.log(data);
$('.page-loader').hide();
$('.load-a').fadeIn(300);
}
})
);
}
$(window).bind('popstate', function(){
replacePage(location.pathname);
});
Thanks in advance!
simple bind new function with blank code
$( "#id" ).bind( "click", function() {
//blank
});
or
used
$('#id').unbind();
Try this,
var requests = [];
function replacePage(url) {
var obj = $(this);
obj.unbind("click", replacePage); //unbind to prevent ajax multiple request
var loading = '<div class="push-load"></div>';
$('.content').fadeOut(200);
$('.container').append(loading);
$.each(requests, function (i, v) {
v.abort();
});
requests.push(
$.ajax({
type: "GET",
url: url,
dataType: "html",
success: function (data) {
var dom = $(data);
//var title = dom.filter('title').text();
var html = dom.find('.content').html();
//alert(html);
//alert("OK");
//$('title').text(title);
obj.bind("click", replacePage); // binding after successfulurl ajax request
$('.push-load').remove();
$('.content').html(html).fadeIn(200);
//console.log(data);
$('.page-loader').hide();
$('.load-a').fadeIn(300);
}
}));
}
Hope this helps,Thank you
