AJAX values from database to html skipped

I have these employee information which display if you click on the employee box. But sometimes the value of some fields returns null even if they have a value but when I retry it will return ok. Is this some code problem? here is my code...
First I store the elements into an object
var uamnumber = $(this).find(".box-list-agents-uamnumber").text();
var agentInfo = $(this).find(".box-list-agents-info").text().split("/");
var agentElement = {
txtUam: $("#search-txt-uam-number"),
txtFirstName: $("#search-txt-first-name"),
txtMiddleName: $("#search-txt-middle-name"),
txtLastName: $("#search-txt-last-name"),
txtContactNumber: $("#search-txt-contact-number"),
txtEmailAddress: $("#search-txt-email-address"),
txtClassification: $("#search-txt-classification"),
txtAgentStatus: $("#search-txt-agent-status"),
txtReasonResignation: $("#search-txt-reason-resignation"),
txtCsp: $("#search-txt-csp-name"),
txtProgramId: $("#search-txt-program-name"),
txtSite: $("#search-txt-site-name"),
txtBirthDate: $("#search-txt-birth-date"),
txtLiveDate: $("#search-txt-live-date"),
txtEndDate: $("#search-txt-end-date"),
txtProgram: $("#search-program-name")
};
var agentParam = {
uam: uamnumber,
csp: agentInfo[0],
program: agentInfo[1]
}
Dashboard_GetAgentInfo(agentParam, agentElement);
$("#search-well-tool-access").hide();
$("#search-well-agent-info").fadeIn();
and here is the function that has been called.
function Dashboard_GetAgentInfo(agentInfo,agentElement) {
$.ajax({
type: "POST",
url: "IROA_StoredProcedures.asmx/Dashboard_GetAgentInfo",
data: JSON.stringify(agentInfo),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
var uamdetails = response.d;
var appendItem = "";
$.each(uamdetails, function (index, Dashboard_GetAgentInfoInfo) {
var uamnumber = Dashboard_GetAgentInfoInfo.uamnumber;
var firstname = Dashboard_GetAgentInfoInfo.firstname;
var middlename = Dashboard_GetAgentInfoInfo.middlename;
var lastname = Dashboard_GetAgentInfoInfo.lastname;
var contactnumber = Dashboard_GetAgentInfoInfo.contactnumber;
var emailaddress = Dashboard_GetAgentInfoInfo.emailaddress;
var csp = Dashboard_GetAgentInfoInfo.csp;
var cspid = Dashboard_GetAgentInfoInfo.cspid;
var program = Dashboard_GetAgentInfoInfo.program;
var programid = Dashboard_GetAgentInfoInfo.programid;
var site = Dashboard_GetAgentInfoInfo.site;
var siteid = Dashboard_GetAgentInfoInfo.siteid;
var birthdate = Dashboard_GetAgentInfoInfo.birthdate;
var livedate = Dashboard_GetAgentInfoInfo.livedate;
var enddate = Dashboard_GetAgentInfoInfo.enddate;
var classification = Dashboard_GetAgentInfoInfo.classification;
var agentStatus = Dashboard_GetAgentInfoInfo.agentstatus;
var reasonResignation = Dashboard_GetAgentInfoInfo.reasonresignation;
$(agentElement.txtUam).val(uamnumber);
$(agentElement.txtFirstName).val(firstname);
$(agentElement.txtMiddleName).val(middlename);
$(agentElement.txtLastName).val(lastname);
$(agentElement.txtContactNumber).val(contactnumber);
$(agentElement.txtEmailAddress).val(emailaddress);
$(agentElement.txtClassification).val(classification);
$(agentElement.txtAgentStatus).val(agentStatus);
$(agentElement.txtReasonResignation).val(reasonResignation);
$(agentElement.txtCsp).val(cspid)
$(agentElement.txtProgramId).val(programid);
$(agentElement.txtSite).val(siteid);
$(agentElement.txtBirthDate).val(birthdate);
$(agentElement.txtLiveDate).val(livedate);
$(agentElement.txtEndDate).val(enddate);
$(agentElement.txtProgram).text(program);
NumbersOnly();
});
},
error: function (XMLhttpRequest) {
alert("error in Dashboard_GetAgentInfo");
console.log(XMLhttpRequest);
}
});
}
and this is the web service that has been called
public List<Dashboard_GetAgentInfoDetails> Dashboard_GetAgentInfo(string uam, int csp, int program) /*int CSP, int Program*/
{
DataTable table = null;
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "[Dashboard_GetAgentInfo]";
cmd.Parameters.AddWithValue("#uam", uam);
cmd.Parameters.AddWithValue("#csp", csp);
cmd.Parameters.AddWithValue("#program", program);
cmd.CommandType = System.Data.CommandType.StoredProcedure;
table = this.dbConn.ExecuteDataTable(cmd);
Dashboard_GetAgentInfo_Details.Clear();
foreach (DataRow row in table.Rows)
{
Dashboard_GetAgentInfoDetails _list = new Dashboard_GetAgentInfoDetails();
_list.uamnumber = row["UAM #"].ToString();
_list.firstname = row["First Name"].ToString();
_list.middlename = row["Middle Name"].ToString();
_list.lastname = row["Last Name"].ToString();
_list.contactnumber = row["Contact Number"].ToString();
_list.emailaddress = row["Email Address"].ToString();

}
return Dashboard_GetAgentInfo_Details;
}
does storing elements into an object and passing it as a parameter is a good practice of coding? and what may be the cause of the select having no value even if I when I try to console.log the value and it returns ok?

I think the problem is here:
$(agentElement.txtUam).val(uamnumber);
$(agentElement.txtFirstName).val(firstname);
...
You should do:
agentElement.txtUam.val(uamnumber);
agentElement.txtFirstName.val(firstname);
...
There is no need to use jquery selector $, because agentElement.txtUam is already one, also gathering elements inside an object is a best practice because you can't pass each one as a parameter.

The perfect answer to this is add a call back function so the dropbox have a option first before adding the val. Here is the idea of adding a callback function
function Filtering_GetSite(siteElement, callback) {
if (typeof (callBack) == "function") {
callBack();
}
}
the line checking of the callback parameter is to ensure that it its a function before executing so you can call the function like this Filtering_GetSite(sample) insted of Filtering_GetSite(sample,function(){}) when omiting the callback function

how to store array value in angularjs and then redirect

$scope.messagearray = {};
$scope.messagewant = function(info) {
$scope.messagearray = info;
$location.path("/messagewant");
}
my code is redirecting without storing value in array

The code can be modified like this. Now info is passed to new location via query parameters.
$scope.messagearray = {};
$scope.messagewant = function(info) {
$scope.messagearray = info;
$location.path("/messagewant?info="+info);
}

Set Value from JSON via AJAX

I'm using Github Gists for a web playground I'm making as a side project. I load two json files into the editor. 1 handles all the libraries (jquery, bootstrap, etc:) and another for the users settings (fontsize, version, etc:)
So anyway I have this JSON named settings
var settings = gistdata.data.files["settings.json"].content
var jsonSets = JSON.parse(settings)
I parse and attempted to grab an object from the JSON and set it as a value of a input textbox.
Now console.log(jsonSets.siteTitle) works perfectly fine
but when I try to change the input dynamically...
$("[data-action=sitetitle]").val(jsonSets.siteTitle).trigger("change")
The problem is it's not actually applying the value!
The only way I've been able to successfully apply the value is...
setTimeout(function() {
$("[data-action=sitetitle]").val(jsonSets.siteTitle).trigger("change")
}, 5000)
Which is ridiculously slow.
Does anyone know why it's not applying the value?
in addition.
How can I solve this problem?
var hash = window.location.hash.substring(1)
if (window.location.hash) {
function loadgist(gistid) {
$.ajax({
url: "https://api.github.com/gists/" + gistid,
type: "GET",
dataType: "jsonp"
}).success(function(gistdata) {
var libraries = gistdata.data.files["libraries.json"].content
var settings = gistdata.data.files["settings.json"].content
var jsonLibs = JSON.parse(libraries)
var jsonSets = JSON.parse(settings)
// Return libraries from json
$.each(jsonLibs, function(name, value) {
$(".ldd-submenu #" + name).prop("checked", value)
})
// Return font settings from json
var siteTitle = jsonSets.siteTitle
var WeaveVersion = jsonSets.version
var editorFontSize = jsonSets.editorFontSize
var WeaveDesc = jsonSets.description
var WeaveAuthor = jsonSets.author
$("[data-action=sitetitle]").val(siteTitle).trigger("change")
$("[data-value=version]").val(WeaveVersion).trigger("change")
$("[data-editor=fontSize]").val(editorFontSize).trigger("change")
$("[data-action=sitedesc]").val(WeaveDesc).trigger("change")
$("[data-action=siteauthor]").val(WeaveAuthor).trigger("change")
}).error(function(e) {
// ajax error
console.warn("Error: Could not load weave!", e)
})
}
loadgist(hash)
} else {
// No hash found
}

My problem was actually related to localStorage.
I cleared it localStorage.clear(); ran the ajax function after and it solved the problem.
var hash = window.location.hash.substring(1)
if (window.location.hash) {
localStorage.clear()
function loadgist(gistid) {
$.ajax({
url: "https://api.github.com/gists/" + gistid,
type: "GET",
dataType: "jsonp",
jsonp: "callback"
}).success(function(gistdata) {
var htmlVal = gistdata.data.files["index.html"].content
var cssVal = gistdata.data.files["index.css"].content
var jsVal = gistdata.data.files["index.js"].content
var mdVal = gistdata.data.files["README.md"].content
var settings = gistdata.data.files["settings.json"].content
var libraries = gistdata.data.files["libraries.json"].content
var jsonSets = JSON.parse(settings)
var jsonLibs = JSON.parse(libraries)
// Return font settings from json
var siteTitle = jsonSets.siteTitle
var WeaveVersion = jsonSets.version
var editorFontSize = jsonSets.editorFontSize
var WeaveDesc = jsonSets.description
var WeaveAuthor = jsonSets.author
$("[data-action=sitetitle]").val(siteTitle)
$("[data-value=version]").val(WeaveVersion)
$("[data-editor=fontSize]").val(editorFontSize)
$("[data-action=sitedesc]").val(WeaveDesc)
$("[data-action=siteauthor]").val(WeaveAuthor)
storeValues()
// Return settings from the json
$(".metaboxes input.heading").trigger("keyup")
// Return libraries from json
$.each(jsonLibs, function(name, value) {
$(".ldd-submenu #" + name).prop("checked", value).trigger("keyup")
})
// Set checked libraries into preview
$("#jquery").trigger("keyup")
// Return the editor's values
mdEditor.setValue(mdVal)
htmlEditor.setValue(htmlVal)
cssEditor.setValue(cssVal)
jsEditor.setValue(jsVal)
}).error(function(e) {
// ajax error
console.warn("Error: Could not load weave!", e)
})
}
loadgist(hash)
} else {
// No hash found
}

Accessing Data from JavaScript Object's Array Member Variable

I'm writing a jQuery plugin for work which pulls in RSS feed data using Google's Feed API. Using this API, I'm saving all of the relevant RSS feed data into an object, then manipulating it through methods. I have a function which is supposed to render the RSS feed onto the webpage. Unfortunately, when I try to display the individual RSS feed entries, I get an error. Here's my relevant code:
var RSSFeed = function(feedTitle, feedUrl, options) {
/*
* An object to encapsulate a Google Feed API request.
*/
// Variables
this.description = "";
this.entries = [];
this.feedUrl = feedUrl;
this.link = "";
this.title = feedTitle;
this.options = $.extend({
ssl : true,
limit : 4,
key : null,
feedTemplate : '<article class="rss-feed"><h2>{title}</h1><ul>{entries}</ul></article>',
entryTemplate : '<li><h3>{title}</h3><p>by: {author} # {publishedDate}</p><p>{contentSnippet}</p></li>',
outputMode : "json"
}, options || {});
this.sendFeedRequest = function() {
/*
* Makes the AJAX call to the provided requestUrl
*/
var self = this;
$.getJSON(this.encodeRequest(), function(data) {
// Save the data in a temporary object
var responseDataFeed = data.responseData.feed;
// Now load the data into the RSSFeed object
self.description = responseDataFeed.description;
self.link = responseDataFeed.link;
self.entries = responseDataFeed.entries;
});
};
this.display = function(jQuerySelector) {
/*
* Displays the RSSFeed onto the webpage
* Each RSSEntry will be displayed wrapped in the RSSFeed's template HTML
* The template markup can be specified in the options
*/
var self = this;
console.log(self);
console.log(self.entries);
};
};
$.rssObj = function(newTitle, newUrl, options) {
return new RSSFeed(newTitle, newUrl, options);
};
// Code to call the jquery plugin, would normally be found in an index.html file
rss = $.rssObj("Gizmodo", "http://feeds.gawker.com/Gizmodo/full");
rss.sendFeedRequest();
rss.display($('div#feed'));
Obviously, my display() function isn't complete yet, but it serves as a good example. The first console.log() will write all of the relevant data to the console, including the entries array. However, when I try to log the entries array by itself, it's returning an empty array. Any idea why that is?

I guess the problem is that display() is called without waiting for the AJAX request to complete. So the request is still running while you already try to access entries - hence the empty array.
In order to solve this you could move the call to display() into the callback of $.getJSON(). You just have to add the required selector as a parameter:
this.sendFeedRequest = function(selector) {
var self = this;
$.getJSON(this.encodeRequest(), function(data) {
var responseDataFeed = data.responseData.feed;
...
self.entries = responseDataFeed.entries;
self.display(selector);
});
};
EDIT:
If you don't want to move display() into the callback, you could try something like this (untested!):
var RSSFeed = function(feedTitle, feedUrl, options) {
...
this.loading = false;
this.selector = null;
this.sendFeedRequest = function() {
var self = this;
self.loading = true;
$.getJSON(this.encodeRequest(), function(data) {
...
self.loading = false;
if (self.selector != null) {
self.display(self.selector);
}
});
};
this.display = function(jQuerySelector) {
var self = this;
if (self.loading) {
self.selector = jQuerySelector;
}
else {
...
}
};
};

Javascript: creating dynamic variables and object names. / html5 localstorage

I'm working on a form that is saved by HTML5 local storage.
When pressing save:
function saveAll(){
var field1 = document.getElementById('field1').value;
localStorage.setItem('con_field1',field1);
var field2 = document.getElementById('field2').value;
localStorage.setItem('con_field2',field2);
var field3 = document.getElementById('field3').value;
localStorage.setItem('con_field3',field3);
var field4 = document.getElementById('field4').value;
localStorage.setItem('con_field4',field4);
var field5 = document.getElementById('field5').value;
localStorage.setItem('con_field5',field5);
var field6 = document.getElementById('field6').value;
localStorage.setItem('con_field6',field6);
}
And when loading the page (fills out the forms):
function ShowAll() {
var field1 = localStorage.getItem('con_field1');
document.conditioning.field1.value = field1;
var field2 = localStorage.getItem('con_field2');
document.conditioning.field2.value = field2;
var field3 = localStorage.getItem('con_field3');
document.conditioning.field3.value = field3;
var field4 = localStorage.getItem('con_field4');
document.conditioning.field4.value = field4;
var field5 = localStorage.getItem('con_field5');
document.conditioning.field5.value = field5;
var field6 = localStorage.getItem('con_field6');
document.conditioning.field6.value = field6;
}
This all works fine, but I want to re-write this in a more fancy and efficient way. I was thinking of something like this:
function ShowAll() {
var field = [];
for (i=0; i<6; i++) {
field[i] = localStorage.getItem(window['con_field' + i]);
document.purpose.field[i].value = window['con_field' + i]
}
}
But the browser is not enjoying this. Basically I need to create a loop that automatically changes the "field" name in to 'field1, field2, field3' etc. The window thing is working, but I'm just using it wrong.
Anyone has an idea?
Thanks a lot!

function showAll(t1,c1,d1) {
var field1 = localStorage.getItem('con_field1');
console.log(field1)
var field2 = localStorage.getItem('con_field2');
var field3 = localStorage.getItem('con_field3');
}

You should add all of your data to one object, stringify it, then add that to local storage under a single key.
When you load it, grab the one local storage item, parse it, then access the properties on the object.
e.g.
var save = function () {
var data = {
foo: 'bar'
};
localStorage.setItem('myData', JSON.stringify(data));
};
var load = function () {
var data = JSON.parse(localStorage.getItem('myData'));
var someProp = data.foo; // gives you 'bar'
};

It looks like your main problem is that the fields are indexed beginning with 1, but your loop indexes from 0.
What about this?
var field = [];
for (i = 1; i <= 6; i++)
{
field[i] = localStorage.getItem(window['con_field' + i]);
document.purpose.field[i].value = window['con_field' + i]
}
Also, I'm not 100% on this, but I think using document.getElementByID is more cross-browser compatible than using bracket notation on the window object, but it's been a while since I wrote plain vanilla JS, so don't quote me.

I would try document.purpose["field" + i].value = window['con_field' + i].
