I am trying to use while loop in Angular.
If I use alert in while loop, it give same quantity output. but I remove alert, the quantity is different. So what is wrong in my code.
var quantity= $scope.quantity;
var i=0;
while(i< quantity)
{
order.createOrderLineItem( localStorage.getItem( "orderID" ), itemStr, undefined, $scope.errorCallback )
.success(function(data){
$scope.lineItemID = data.id;
alert("i:"+i);
var orderLineItemData = {};
if( $scope.cusNote == "" )
{
var existedNote = data.note || "";
orderLineItemData = {
"unitQty": $scope.quantity,
"note": existedNote,
};
//if adding taxRates 0, clover will returns error
if($scope.taxRates !== 0) {
orderLineItemData.taxRates = $scope.taxRates;
}
}
else
{
var customerNote = "";
if( data.note != undefined && data.note != null ) customerNote = data.note;
customerNote = customerNote + "#order-request-[";
customerNote = customerNote + $scope.cusNote;
customerNote = customerNote + "]";
customerNote = customerNote.replace(/\\/g, '\\\\');
customerNote = customerNote.replace(/\"/g, '\\"');
console.log( "customerNote:" + customerNote );
orderLineItemData = {
"unitQty":$scope.quantity,
"note": customerNote,
"taxRates": $scope.taxRates
}
}
order.updateOrderLineItem( localStorage.getItem( "orderID" ), $scope.lineItemID, JSON.stringify(orderLineItemData), undefined, $scope.errorCallback )
.success( function( data ){
if( $scope.modCount == 0 )
{
location.href = "/" + $routeParams.slug;
}
$scope.addModifierItem( $scope.lineItemID );
});
});
i++;
}
So how can I correct this code?
I am not sure but, alert may be the reason of that. Can you try to use console.log("i:"+i); instead of the alert. Browser may interrupt when you use alert because of the pop up.
--Edited--
this is the service that you will need to implement into your application. You will need to notify this service at your success and it will trigger any observe that is implemented after the notify
app.service('checkService',['$q',function($q){
var checkRequest = $q.defer();
this.notifyRequestIsDone= function(){
checkRequest .notify();
};
this.observeRequestStatus = function(){
return checkRequest .promise;
};
}]);
Here is observe example of the code above add this to your controller where you need to increase your value after the request is done
checkService.observeRequestStatus ().then(null,null,function(){
//... Your code
});

i was developing sharetronix script but there is something realy odd about this script i can see in console network request goes for example for this address
http://localhost/ajax/postform-submit/ajaxtp:xml/r:0
but i cant find any folder with postform-submit name.i know this is possible with redirection using htaccess but i cant find anything in htaccess file.
this is part of js code where this request send
function postform_submit_step4()
{
var req = ajax_init(true);
if( ! req ) { return; }
var p = "post_temp_id="+encodeURIComponent(pf_data.temp_id)+"&message="+encodeURIComponent(pf_data.message);

req.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
req.send(p);
}
how is this possible when there is no redirection?
The script is not odd: the way an URL maps to a file not always is so straightforward.
Most web frameworks, for example, use a router/dispatcher to decide what to do/which file to serve given a specific URL.
For example, most MVC web frameworks by default would handle this URL:
http://www.example.com/users/edit/5
by calling the action/method "edit" of the controller "users" passing an argument 5.
Long story short, redirects are not the only way an URL can be mapped to a physical file on the webserver.
To find which file is served or which file contains the code that is executed to produce what you receive, you first need to know which application server/framework is used, and learn how it works.
I am using infinite scroll to load posts and tried to integrate a custom like button for every single posts that needs a small jquery script to work. My problem is I added this Jquery directly after the sucess in ajax load posts. But when I load eg the 3. page my jquery script executes twice and on the posts of the 2nd page the lke buttons are not working correctly. How can I handle this? If I dont execute the code after the ajax request and only call this jquery code globally the like buttons do not work in the new loaded posts of the ajax infinite scroll. Maybe I need to stop the sript of before when eg loadin 3. page through the ajax infinite scroll but how? This is my code:
function load_more_posts(selector){
var url = $(selector).attr('href');
var data;
loading = true;
$.ajax({
url: url,
data: data,
success: function( data ) {

There's a great plugin for scrolling. He has methods such as bund, unbind, destroy and e.t.c.:
https://github.com/infinite-scroll/infinite-scroll#methods
I have this code on my html page:
<span data-miid="{{ orden._id }}"
data-fetxa="{{orden.fetxa}}"
data-linea="1"
ng-mouseenter="arraton(orden.ref);"
ng-click="grafikoa(orden.ref);"
ng-if="isadmin"
ng-bind-html="orden.ref"
>{{orden.ref}}</span>
And this is the angular part:
$scope.arraton = function(val) {
if ( ( val === "" ) || ( val === undefined ) ) { return false; }
var of="";
val = val.replace("<BR>", "<br>");
val = val.replace("<BR />", "<br>");
val = val.replace("<br />", "<br>");
if (val === undefined) {
return false
}
var n = val.indexOf("<br>");
if (n > 0) {
var miarray = val.split('<br>');
of = miarray[1];
}
var url = "SOMEURL/delaoferta?of="+of;
$http.get(url)
.success(function (data) {
$scope.arraton = "A Frabricar: " + parseInt(data.QFabricar)
+ "<br />Iniciada: " + parseInt(data.QIniciada)
+ "<br />Fabricada: " + parseInt(data.QFabricada);
})
.error(function () {
console.log("error al obtener datos");
return;
});
}
The fact is that when I mouse over the span, the first time works fine, but then, I´m getting
TypeError: string is not a function
all the time a mouse over the span.
Any help or clue?
thx
The problem is the success of yout $http request, your setting an string when your ng-mouseenter need a function. Change a variable name and you are done.

I'm trying to convert antirez's autocompleter to javascript to use it with node.js.
I can't pass the closure Problem. Maybe someone can help me out.
I see where the problems are but can't figure out how to solve them.
The while loop is firing, the break is not correct and won't work etc.
Code:
var acp = {
vars: {
dict : false,
count : false,
prefix : false,
rangeLen : 10,
start : false,
results : false,
range : false,
},
sendResults: function(){
console.log(acp.vars.results);
},
getzrank: function(){
redis.zrank( acp.vars.dict, acp.vars.prefix, function( err, start ){
acp.vars.start = start;
});
},
getzrange: function(){
redis.zrange( acp.vars.dict, acp.vars.start, parseFloat( acp.vars.start+acp.vars.rangeLen-1 ), function( err, range ){
acp.vars.range = range;
});
},
createAutocomplete: function(){
while( acp.vars.results.length != acp.vars.count ){
acp.getzrange();
acp.vars.start+=acp.vars.rangeLen;
if( ! acp.vars.range || acp.vars.range.length == 0 ) { break; }
for ( var i in acp.vars.range ){
var minLen = Math.min(i.length,acp.vars.prefix.length);
if( i.substr( 0, minLen ) != acp.vars.prefix.substr( 0, minLen ) ){
acp.vars.count = acp.vars.results.length;
}
if( i.substr( 0, i.length-1 ) == "*" && acp.vars.results.length != acp.vars.count) {
acp.vars.results.push( i.substr(0,-1) );
}
}
}
acp.sendResults();
},
init: function(dict,prefix,count){
acp.vars.range = false;
acp.vars.dict = dict;
acp.vars.prefix = prefix;
acp.vars.count = count;
acp.vars.results = [];
acp.vars.start = acp.getzrank();
if( ! acp.vars.start ){ acp.sendResults(); }
else{ acp.createAutocomplete(); }
}
}
The break statement is outside the scope of the while loop since its nested in the anonymous function. Not sure if that solves your problem.
I'm having trouble uploading a file using a Javascript function that makes an Ajax call to a servlet. The file is uploaded perfectly when I use chrome, but not when I use IE8 (Go figure).
I used to have a file select button on the bottom of my form. When I clicked that button a function would be called and it would upload the file to the servlet using ajax. This worked perfectly in IE8, but the client wanted links instead. So now I have the links in the form, and the buttons hidden with css. The links call the click event of the buttons. Now the file uploading only works with Chrome, and not IE8.
The request never makes it to the servlet for some reason, and for some reason the ajax request returns success. Any idea what the problem might be?
Here is my code:
//Uploading a file
$("#uploaded_file").change(function() {
var filename = $(this).val();
if(isAcceptable(filename)) {
$.ajaxFileUpload
(
{
type: "POST",
url:'GenerateServlet',
secureuri:false,
fileElementId:'uploaded_file',
dataType: 'json',
success: function (data, status)
{
if(typeof(data.error) != 'undefined')
{
if(data.error != '')
{
alert(data.error);
}else
{
alert(data.msg);
}
}
fillTemplate(data);
}
}
)
}
else if(filename.length > 0){
$("#uploaded_file").val("");
alert("Invalid File! Please select another file")
}
});
$("#upload_link").click(function() {
document.getElementById('uploaded_file').click();
return false;
});
Here is the upload function:

That is a typical Microsoft security measure (e.g. to stop automated uploads).
That means you have to originate an upload from an actual user-pressed button click.
Style the button to make it look like a link instead.
