I am new to Ajax and Jquery.I have a form where there is a DepositAccountNumberId text box and its value is stored in a Hidden Field for Validation.
OnBlur event of DepositAccountNumberId TextBox should give a bootbox alert ("This Account Number has been Suspended"). I have posted the code below:
Javascript Function to CheckAccountSuspension()
var exist = true;
function checkAccountSuspension() {
var accountNumberId = $('#DepositAccountNumberIdHiddenField').val();
// alert(accountNumberId);
if (accountNumberId == "") {
//
} else {
try {
var url = '/WebMethods/AccountDetails.asmx/IsAccountSuspended';
var d = { accountNumberId: accountNumberId };
//var jqXhr = $.post(url, d);
//jqXhr.done(function(data) {
$.post(url, d, function (data) {
if (data) {
var ret = data.d;
if (ret) {
$('#DepositAccountNumberIdHiddenField').val(accountNumberId);
exist = true;
} else {
$('#DepositAccountNumberIdHiddenField').val('');
bootbox.alert("This Account Has been Suspended");
exist = false;
}
}
}).fail(function() {
$('#DepositAccountNumberIdHiddenField').val('');
});
} catch (e) {
bootbox.alert('Error: ' + e);
}
}
Web Method
[WebMethod(EnableSession = true)]
public bool IsAccountSuspended(string accountNumberId)
{
int officeId = OfficeId;
return BusinessLayer.Transactions.Transactions.IsAccountSuspended(officeId, accountNumberId.ToLong());
}
IsAccountSuspended in Business Layer
public static bool IsAccountSuspended(int officeId, long accountNumberId)
{
if (accountNumberId <= 0)
{
return false;
}
return DatabaseLayer.Transactions.Transactions.IsAccountSuspended(officeId,accountNumberId);
}
IsAccountSuspended in Database Layer
public static bool IsAccountSuspended(int officeId, long accountNumberId)
{
if (accountNumberId <= 0)
{
return false;
}
var sql = "SELECT * FROM deposit.is_suspended(#AccountNumberId::bigint);";
using (var command = new NpgsqlCommand(sql))
{
command.Parameters.AddWithValue("#AccountNumberId", accountNumberId);
using (var table = DBOperations.GetDataTable(command))
{
if (table.Rows.Count >= 1)
{
return true;
}
return false;
}
}
}
The Validation does not work.The ajax is not called to check if the account is suspended.Help Please.
Try to use $.post method:
var exist = true;
function checkAccountSuspension() {
var accountNumberId = $('#DepositAccountNumberIdHiddenField').val();
// alert(accountNumberId);
if (accountNumberId == "") {
//
} else {
try {
var url = '/WebMethods/AccountDetails.asmx/IsAccountSuspended';
var d = {accountNumberId: accountNumberId};
var jqXhr = $.post(url, d);
jqXhr.done(function (data) {
if (data) {
var ret = data.d;
if (ret) {
$('#DepositAccountNumberIdHiddenField').val(accountNumberId);
exist = true;
} else {
$('#DepositAccountNumberIdHiddenField').val('');
bootbox.alert("This Account Has been Suspended");
exist = false;
}
}
}).fail(function () {
$('#DepositAccountNumberIdHiddenField').val('');
});
} catch (e) {
bootbox.alert('Error: ' + e);
}
}
}
$('#DepositAccountNumberTextBox').on('blur', function () {
checkAccountSuspension();
});
There is no such method like ajaxPost in JQuery. Use $.Post at its place.
try {
var url = '/WebMethods/AccountDetails.asmx/IsAccountSuspended';
var d = { accountNumberId: accountNumberId };
$.post(url,d,function(data){
if (data) {
var ret = data.d;
if (ret) {
$('#DepositAccountNumberIdHiddenField').val(accountNumberId);
exist = true;
}
else {
$('#DepositAccountNumberIdHiddenField').val('');
bootbox.alert("This Account Has been Suspended");
exist = false;
}
}
}).error(function() {
$('#DepositAccountNumberIdHiddenField').val('');
})
}
catch (e) {
bootbox.alert('Error: ' + e);
}
This is How it worked.
Like some of the experts above said about the use of postAjax and $.post.
As everywhere in the project it was used as postAjax by previous developers here.
I was actually passing a null value again in the hidden field.
This code worked.
var exist = true;
function checkAccountSuspension() {
var accountNumberId = $('#DepositAccountNumberIdHiddenField').val();
if (accountNumberId == "") {
//
} else {
try {
var url = '/WebMethods/AccountDetails.asmx/IsAccountSuspended';
var d = { accountNumberId: accountNumberId };
//$.post(url, d, function (data) {
var jqXhr = ajaxPost(url, d, true);
jqXhr.done(function (data) {
var ret = data.d;
if (!ret) {
$('#DepositAccountNumberIdHiddenField').val(accountNumberId);
exist = true;
}
else {
//$('#DepositAccountNumberIdHiddenField').val('');
// bootbox.alert("<b class='text-red'>Suspended Account</b> <br/>This Account has been Suspended.");
swal({
title: "Suspended Account!",
text: "This Account is Suspended",
type: "error",
confirmButtonText: "OK",
imageSize: "20x20"
});
exist = false;
resetAllInputs();
}
}).fail(function (ex) {
bootbox.alert("Requested process fail to execute");
//$('#DepositAccountNumberIdHiddenField').val('');
});
}
catch (e) {
bootbox.alert('Error: ' + e);
}
}
}
I am trying to display content in full screen in IE using Full Screen API everything works fine except IE below is code, any help would be great.thank you in advance.
JAVASCRIPT CODE:
(function() {
var
fullScreenApi = {
supportsFullScreen: false,
isFullScreen: function() { return false; },
requestFullScreen: function() {},
cancelFullScreen: function() {},
fullScreenEventName: '',
prefix: ''
},
browserPrefixes = 'webkit moz o ms khtml'.split(' ');
// check for native support
if (typeof document.cancelFullScreen != 'undefined') {
fullScreenApi.supportsFullScreen = true;
} else {
// check for fullscreen support by vendor prefix
for (var i = 0, il = browserPrefixes.length; i < il; i++ ) {
fullScreenApi.prefix = browserPrefixes[i];
if (typeof document[fullScreenApi.prefix + 'CancelFullScreen' ] != 'undefined' ) {
fullScreenApi.supportsFullScreen = true;
break;
}
}
}
// update methods to do something useful
if (fullScreenApi.supportsFullScreen) {
fullScreenApi.fullScreenEventName = fullScreenApi.prefix + 'fullscreenchange';
fullScreenApi.isFullScreen = function() {
switch (this.prefix) {
case '':
return document.fullScreen;
case 'webkit':
return document.webkitIsFullScreen;
default:
return document[this.prefix + 'FullScreen'];
}
}
fullScreenApi.requestFullScreen = function(el) {
return (this.prefix === '') ? el.requestFullScreen() : el[this.prefix + 'RequestFullScreen']();
}
fullScreenApi.cancelFullScreen = function(el) {
return (this.prefix === '') ? document.cancelFullScreen() : document[this.prefix + 'CancelFullScreen']();
}
}
// jQuery plugin
if (typeof jQuery != 'undefined') {
jQuery.fn.requestFullScreen = function() {
return this.each(function() {
var el = jQuery(this);
if (fullScreenApi.supportsFullScreen) {
fullScreenApi.requestFullScreen(el);
}
});
};
}
// export api
window.fullScreenApi = fullScreenApi;
})();
</script>
<script>
var fsButton = document.getElementById('fsbutton');
var fsElement = document.getElementById('container');
if (window.fullScreenApi.supportsFullScreen) {
// handle button click
fsButton.addEventListener('click', function() {
//alert(fsElement);
window.fullScreenApi.requestFullScreen(fsElement);
//alert("hi");
}, true);
fsElement.addEventListener(fullScreenApi.fullScreenEventName, function() {
if (fullScreenApi.isFullScreen()) {
alert("yes");
//fsStatus.innerHTML = 'Whoa, you went fullscreen';
} else {
alert("no");
// fsStatus.innerHTML = 'Back to normal';
}
}, true);
} else {
alert("no");
// fsStatus.innerHTML = 'SORRY: Your browser does not support FullScreen';
}
</script>
HTML CODE:
<div>
<div id="container" >
..... content goes here
</div>
<input type="button" id="fsbutton" title="View Full Screen">
</div>
I didn't try it but I think that it's because IE doesn't use the camelCase for "Fullscreen" in "cancelFullscreen" and "requestFullscreen", which is the actual live standard recommandation btw.
Other browsers are wrong this time.
I'm using the FoxyComplete plugin with Jquery Auto-Complete to do a simple search. Everything is setup and working great but I'm finding the search results extremely limiting.
I use a big JSON file for all of my data and the problem I'm having is in the following case: Let's assume that my JSON file has the following description:
{
"title": "Brand new black car"
},
If a user searches "black car", he or she will get the result perfectly and the search is great. BUT, if a user search "car new", nothing comes up even though both keywords are in my JSON file.
Any help would be great. I poured through the Jquery AutoComplete docs and couldn't find a solution either. My Jquery autocomplete js is below:
;
(function ($) {
$.fn.extend({
autocomplete: function (urlOrData, options) {
var isUrl = typeof urlOrData == "string";

data: isUrl ? null : urlOrData,
delay: isUrl ? $.Autocompleter.defaults.delay : 10,
max: options && !options.scroll ? 10 : 150
}, options);
// if highlight is set to false, replace it with a do-nothing function
options.highlight = options.highlight || function (value) {
return value;
};
// if the formatMatch option is not specified, then use formatItem for backwards compatibility
options.formatMatch = options.formatMatch || options.formatItem;
return this.each(function () {
new $.Autocompleter(this, options);
});
},
result: function (handler) {
return this.bind("result", handler);

I have functions on blur and on focus that change a password text field to change from text to password type. What happens is that we deleted and recreate it, but the prototype functions don't work afterwards. The code is as follows:
function focusPass(inputel,inputval) {
if(inputel.value == inputval) {
var newInput = document.createElement('input');
newInput.setAttribute('type','password');
newInput.setAttribute('name',inputel.getAttribute('name'));
newInput.setAttribute('id',inputel.getAttribute('id'));
inputel.parentNode.replaceChild(newInput,inputel);
setTimeout(function() { newInput.focus(); }, 10);
}
}
function blurPass(inputel,inputval) {
if(inputel.value == '') {
var newInput = document.createElement('input');
newInput.setAttribute('type','text');
newInput.setAttribute('name',inputel.getAttribute('name'));
newInput.setAttribute('id',inputel.getAttribute('id'));
newInput.value = inputval;
inputel.parentNode.replaceChild(newInput,inputel);
}
}
if ($('j_password') != undefined) {
blurPass($('j_password'),'password');
$('j_password').observe('blur', function(e) {
blurPass(this,'password');
});
$('j_password').observe('focus', function(e) {
focusPass(this,'password');
});
}
I tried doing something like:
document.observe('blur', function(e, el) {
if (el = e.findElement('#j_password')) {
blurPass(this,'password');
}
});
document.observe('focus', function(e, el) {
if (el = e.findElement('#j_password')) {
focusPass(this,'password');
}
});
but that doesn't seem to do anything. Can someone tell me how I would keep this function working? I would prefer not to have to set an attribute for onblur and onfocus, but if it's not possible, will revert to that.
Thanks.
What I ended up doing was:
function focusPass(inputel,inputval) {
if(inputel.value == inputval) {
var ie = getIEVersion();
if (ie > -1 && ie < 9) {
var newInput = document.createElement('input');
newInput.setAttribute('type','password');
newInput.setAttribute('name',inputel.getAttribute('name'));
newInput.setAttribute('id',inputel.getAttribute('id'));
new Insertion.After(inputel, newInput);
inputel.remove();
setTimeout(function() { newInput.focus(); }, 10);
} else {
inputel.setAttribute('type','password');
inputel.value = "";
inputel.focus();
}
}
}
function blurPass(inputel,inputval) {
if(inputel.value == '') {
var ie = getIEVersion();
if (ie > -1 && ie < 9) {
var newInput = document.createElement('input');
newInput.setAttribute('type','text');
newInput.setAttribute('name',inputel.getAttribute('name'));
newInput.setAttribute('id',inputel.getAttribute('id'));
newInput.value = inputval;
new Insertion.After(inputel, newInput);
inputel.remove();
} else {
inputel.setAttribute('type','text');
inputel.value = inputval;
}
}
}
It doesn't fix the IE7 and IE8 issues, but at least it works on all other major browsers as they support changing the input type.

This is the error I received
TypeError: Result of expression '$('.navigation')' [null] is not an object. Can anybody please explain to me why this error occur?
You receive this error because if the following function in the first code:
function $(id) {
return document.getElementById(id);
}
This overlaps with jQuery's $ function which is required by the second piece of code. rewrite the first piece of code to use jQuery's $() function or rename $() in the first piece of code and find/replace.
Do you have html elements with the class name "navigation" in your code?
