Jquery Address Plugin Post issue - jquery-plugins

Hi I am learning to use the Jquery Address plugin, and am using the tutorial over
here
So here is the html
Test 1<br />
Test 2
Load Area: <br />
<div id="area"></div>
And here is the Jquery code
function loadURL(url) {
$("#area").load(url);
}
// Event handlers
$.address.init(function(event))
.change(function(event) {
$("#area").load($('[rel=address:' + event.value + ']').attr('href'));
})
$('a').click(function(){
loadURL($(this).attr('href'));
});
Now this works well. However I want to do a POST call on the back button. So I replace
$("#area").load($('[rel=address:' + event.value + ']').attr('href'));
with
var myhref = $('[rel=address:' + event.value + ']').attr('href');
$.post(myhref, function(data) {
$('#area').html(data);
});
This throws the console error "this.value is not a function".
Considering my very superficial knowledge of Jquery (& programming in general), what am I doing wrong here?

Aw man I wish someone could answer this. I've been trying to get this thing to POST for a day now.. It just wants to get everything it seems, but I am at a loss of how I would tweak it to post.

function loadURL(url) {
$.post(url, function(data){
$("#area").html(data);
})
}
// Event handlers
$(document).ready(function(){
$("a").click(function(e){
e.preventDefault();
$.address.value($(this).attr("href"));
$.post($(this).attr("href"), function(data){
$("#area").html(data);
})
return false;
})
})
$(document).ready(function(){
$.address.init(function(event) { // Initates the address plugin
}).externalChange(function(event) { //externalChange is browser back/fwd button/address bar
if(event.path != "/"){
loadURL(event.path);
}
})
})

How to post information in CasperJS

The following is the html I wanna tackle with.
I wanna post a query and see the weather reports for that city. I tried my codes:
var casper = require('casper').create();
var utils = require('utils');
casper.start('http://www.weather.com.cn/weather1d/101210101.shtml');
casper.waitForSelector('input', function()
{
this.fillXPath('div.search clearfix',{'//input[#id="txtZip"]':'shijiazhuang'},true);
});
casper.then(function()
{
utils.dump(this.getTitle());
});
casper.run();
It did not print the web paeg title on the console. I also tried this:
casper.waitForSelector('input', function()
{
this.fillSelectors('div.search clearfix',{'input[id="txtZip"]':'shijiazhuang'},true);
});
}
);
I did not get any web page title also. I got quite confused and did not what I had done wrong. Besides, it seems that this.fill method only tackles with name attributes to post information on CasperJS's official website. I need your help.
CasperJS script:
var casper = require('casper').create(), utils = require('utils');
casper
.start('http://www.weather.com.cn/weather1d/101210101.shtml',function(){
this
.wait(3000,function(){
this.capture('search.png');
utils.dump(this.getTitle());
})
.evaluate(function(){
document.getElementById('txtZip').value='shijiazhuang';
document.querySelector('input[type="button"]').click();
})
})
.run();
Result:
"【石家庄天气】石家庄今天天气预报,今天,今天天气,7天,15天天气预报,天气预报一周,天气预报15天查询"
search.png
You are doing it correct, you only have to modify your script a little bit.
Just modify the selector of the input field the actual don't seems to work, then you should get the correct result.
"this.fillXPath" only fills up the form and don't post it.
...
// fill the form
casper.waitForSelector('input', function() {
this.fillXPath('#txtZip', {
'//input[#id="txtZip"]': 'shijiazhuang'
}, true);
});
// trigger - post the form
casper.then(function() {
this.click('#btnZip');
});
// i can't speak chinese - wait for some specific change on this page
casper.wait(5000);
// take a screenshot of it
casper.then(function() {
this.capture("shijiazhuang_weather.png");
});

getjson does not work on production server but works on development machine

I have following javascript that is using a selection changed to fill in a select list.
$(function () {
$("#bedrijvenauto").each(function () {
var target = $(this);
var dest = target.attr("data-autocomplete-destination");
target.autocomplete({
source: target.attr("data-autocomplete-source"),
select: function (event, ui) {
alert('selected bedrijf');
event.preventDefault();
target.val(ui.item.label);
$(dest).val(ui.item.value);
$("#projectenauto").val("");
alert('selected bedrijf');
alert($('#BEDRIJF_ID').val());
$.getJSON("/Project/GetListViaJson", { bedrijf: $('#BEDRIJF_ID').val() }, function (data) {
alert('selected bedrijf');
alert(data);
$("#PROJECT_ID").empty();
$("#PROJECT_ID").append(new Option("Maak een selectie", 0));
for (var i = 0; i < data.length; ++i) {
alert(data[i].value + ' ' + data[i].label);
$("#PROJECT_ID").append(new Option(data[i].label, data[i].value));
}
});
},
focus: function (event, ui) {
event.preventDefault();
target.val(ui.item.label);
}
});
target.val($("#BEDRIJF_NAAM").val());
});
It works like a charm on my development pc. The alert are all coming out even the data is returning results. That is the difference with the development pc that does not give any results after the call to getJSON
I have the feeling I am missing a detail here.
I am not used to debugging on a webserver because I usually create GUI applications in WPF, and this is a student's work for his vacation and I now got to get it working without him being around anymore. Vacation is done :-(
But not for me.
The 404 error indicated in your comments means the url your creating is incorrect. Always make use of the #Url.Action() method to ensure they are correctly generated. In your script
var url = '#Url.Action("GetListViaJson", "Project")';
$.getJSON(url, { bedrijf: $('#BEDRIJF_ID').val() }, function (data) {
....
}
or if this is an external script, then add the var url = '#Url.Action(...)'; in the main view (razor code is not evaluated in external script files), or add it as a data- attribute to the element your handling
data-url = "#Url.Action(...)"
and get it again using var url = $(someElement).data('url');

angularjs make serial actions by condition

i'd like to do user friendly action at my app.
The issue is:
I have one button. When user 'mousedown' on it, i send ajax query to server to get some info. What i want is to show that info only after user 'mouseup' on this button. In other words, when he releases mouse button.
The problem is that user can release mouse button before or after server answers to my ajax call, by i still want to show info only after release button.
I think i can do this with deferred stuff, by i don't have a lot experience in this. Can you give me some info, how to do this?
Example code:
.html
<input type='button' ng-start='start()' ng-end='end()' >
.js
$scope.start = function(){
$http.get(url, data).success(function(result){})
}
$scope.end = function(){
//show result from first function
}
Tried to do it with use of $q, but it appears that $q is not necessary.
.html
<input type='button' ng-mousedown='start()' ng-mouseup='end()' >
<div ng-show="loaded && resolved" ng-bind="processedResult"></div>
.js
$scope.start = function(){
$scope.resolved = false;
$scope.loaded = false;
$http.get(url, data).success(function(result){
$scope.loaded = true;
$scope.processedResult = processResult(result);
});
};
$scope.end = function(){
$scope.resolved = true;
};
I think, i've solved my problem with pretty promise feature.
.html
<input type='button' ng-start='start()' ng-end='end()' >
.js
$scope.start = function() {
promise = $q.when($scope.ApiCall())
.then(function(result){
return result.data;
}, function(error){
console.log(error);
})
;
};
$scope.end = function() {
promise.then(function(result){
processResult(result.datat);
});
};
$scope.ApiCall = function(){
var data = {};
return $http.get(url, {params: data});
}

Running into Error while waiting for Protractor to sync with the page with basic protractor test

describe('my homepage', function() {
var ptor = protractor.getInstance();
beforeEach(function(){
// ptor.ignoreSynchronization = true;
ptor.get('http://localhost/myApp/home.html');
// ptor.sleep(5000);
})
describe('login', function(){
var email = element.all(protractor.By.id('email'))
, pass = ptor.findElement(protractor.By.id('password'))
, loginBtn = ptor.findElement(protractor.By.css('#login button'))
;
it('should input and login', function(){
// email.then(function(obj){
// console.log('email', obj)
// })
email.sendKeys('josephine#hotmail.com');
pass.sendKeys('shakalakabam');
loginBtn.click();
})
})
});
the above code returns
Error: Error while waiting for Protractor to sync with the page: {}
and I have no idea why this is, ptor load the page correctly, it seem to be the selection of the elements that fails.
TO SSHMSH:
Thanks, your almost right, and gave me the right philosophy, so the key is to ptor.sleep(3000) to have each page wait til ptor is in sync with the project.
I got the same error message (Angular 1.2.13). My tests were kicked off too early and Protractor didn't seem to wait for Angular to load.
It appeared that I had misconfigured the protractor config file. When the ng-app directive is not defined on the BODY-element, but on a descendant, you have to adjust the rootElement property in your protractor config file to the selector that defines your angular root element, for example:
// protractor-conf.js
rootElement: '.my-app',
when your HTML is:
<div ng-app="myApp" class="my-app">
I'm using ChromeDriver and the above error usually occurs for the first test. I've managed to get around it like this:
ptor.ignoreSynchronization = true;
ptor.get(targetUrl);
ptor.wait(
function() {
return ptor.driver.getCurrentUrl().then(
function(url) {
return targetUrl == url;
});
}, 2000, 'It\'s taking too long to load ' + targetUrl + '!'
);
Essentially you are waiting for the current URL of the browser to become what you've asked for and allow 2s for this to happen.
You probably want to switch the ignoreSynchronization = false afterwards, possibly wrapping it in a ptor.wait(...). Just wondering, would uncommenting the ptor.sleep(5000); not help?
EDIT:
After some experience with Promise/Deferred I've realised the correct way of doing this would be:
loginBtn.click().then(function () {
ptor.getCurrentUrl(targetUrl).then(function (newURL){
expect(newURL).toBe(whatItShouldBe);
});
});
Please note that if you are changing the URL (that is, moving away from the current AngularJS activated page to another, implying the AngularJS library needs to reload and init) than, at least in my experience, there's no way of avoiding the ptor.sleep(...) call. The above will only work if you are staying on the same Angular page, but changing the part of URL after the hashtag.
In my case, I encountered the error with the following code:
describe("application", function() {
it("should set the title", function() {
browser.getTitle().then(function(title) {
expect(title).toEqual("Welcome");
});
});
});
Fixed it by doing this:
describe("application", function() {
it("should set the title", function() {
browser.get("#/home").then(function() {
return browser.getTitle();
}).then(function(title) {
expect(title).toEqual("Welcome");
});
});
});
In other words, I was forgetting to navigate to the page I wanted to test, so Protractor was having trouble finding Angular. D'oh!
The rootElement param of the exports.config object defined in your protractor configuration file must match the element containing your ng-app directive. This doesn't have to be uniquely identifying the element -- 'div' suffices if the directive is in a div, as in my case.
From referenceConf.js:
// Selector for the element housing the angular app - this defaults to
// body, but is necessary if ng-app is on a descendant of <body>
rootElement: 'div',
I got started with Protractor by watching the otherwise excellent egghead.io lecture, where he uses a condensed exports.config. Since rootElement defaults to body, there is no hint as to what is wrong with your configuration if you don't start with a copy of the provided reference configuration, and even then the
Error while waiting for Protractor to sync with the page: {}
message doesn't give much of a clue.
I had to switch from doing this:
describe('navigation', function(){
browser.get('');
var navbar = element(by.css('#nav'));
it('should have a link to home in the navbar', function(){
//validate
});
it('should have a link to search in the navbar', function(){
//validate
});
});
to doing this:
describe('navigation', function(){
beforeEach(function(){
browser.get('');
});
var navbar = element(by.css('#nav'));
it('should have a link to home in the navbar', function(){
//validate
});
it('should have a link to search in the navbar', function(){
//validate
});
});
the key diff being:
beforeEach(function(){
browser.get('');
});
hope this may help someone.
I was getting this error:
Failed: Error while waiting for Protractor to sync with the page: "window.angular is undefined. This could be either because this is a non-angular page or because your test involves client-side navigation, which can interfere with Protractor's bootstrapping. See http://git.io/v4gXM for details"
The solution was to call page.navigateTo() before page.getTitle().
Before:
import { AppPage } from './app.po';
describe('App', () => {
let page: AppPage;
beforeEach(() => {
page = new AppPage();
});
it('should have the correct title', () => {
expect(page.getTitle()).toEqual('...');
})
});
After:
import { AppPage } from './app.po';
describe('App', () => {
let page: AppPage;
beforeEach(() => {
page = new AppPage();
page.navigateTo();
});
it('should have the correct title', () => {
expect(page.getTitle()).toEqual('...');
})
});
If you are using
browser.restart()
in your spec some times, it throws the same error.
Try to use
await browser.restart()

jplayer+Ajax inserted content

I am using jPlayer to play audio files.
If I use the player on content, which is privided, when the page gets loaded, it works without any problems.
I also need it for HTML which is inserted by AJAX. Here it does not work. It seems, that the ready event is not triggered.
I wrote a function, which can be executed by click(). In that way, I can click it manually, when the HTML which contains the player is fully loaded. Here I have the same problem: The ready event is not triggered.
This is my function which works on non ajax inserted players fine:
$('.jp-jplayer').each(function () {
var src = $(this).attr('data-src');
var id = $(this).attr('id');
var post_id = $(this).attr('data-id');
alert('beg');
$('#' + id).jPlayer({
ready: function () {
$(this).jPlayer('setMedia', {
mp3: "/prelisten/_lofidl/change_of_heart_full_lofi.mp3",
});
alert('#' + id);
},
swfPath: "/wp-content/themes/Dark_3Chemical_DE_mit_Pagenavi/Dark_3Chemical_DE/audioplayer/js",
//////ERRRROOOOOR
solution: "flash, html",
supplied: "mp3",
wmode: "window",
cssSelectorAncestor: "#jp_container_" + post_id,
play: function () { // To avoid both jPlayers playing together.
$(this).jPlayer("pauseOthers");
},
repeat: function (event) { // Override the default jPlayer repeat event handler
if(event.jPlayer.options.loop) {
$(this).unbind(".jPlayerRepeat").unbind(".jPlayerNext");
$(this).bind($.jPlayer.event.ended + ".jPlayer.jPlayerRepeat", function () {
$(this).jPlayer("play");
debug($(this));
});
} else {
$(this).unbind(".jPlayerRepeat").unbind(".jPlayerNext");
$(this).bind($.jPlayer.event.ended + ".jPlayer.jPlayerNext", function () {
//$("#jquery_jplayer_4858").jPlayer("play", 0);
});
}
},
});
$("#jplayer_inspector").jPlayerInspector({
jPlayer: $('#' + id)
});
});
Currently I am setting the src manually to exclude any possible errors here.
How can I get this function running on AJAX inserted content?
EDIT:
This is the code, which fetches the html including the players:
$.get('/query_posts.php', {
paged: _page,
cats: cols
}, function(data) {
$('#search-results').append(data).fadeIn(300);
//create_player_scripts();
//set_players();
$('#search-results').find('input[name="cartLink"]').each(function() {
$(this).val($(this).closest('.post1').find('.post_headl a').attr('href'));
});
});
To make an AJAX page reload work I had to first destroy all jplayer instances. So I wrote a little function that grabs all instances of a jplayer on the site (by looking for jp-audio classes) and calls jplayer('destroy'); and jplayer('clearMedia'). This function gets called in the $.ajax({ beforeSend: destroyJplayerInstances(); })
UPDATE:
Here is a statement from the developer of jPlayer, Mark Panaghiston:

Hope that helps!
