I'm trying to create an if/else statement within my jQuery code that changes the ajax URL and success function that gets fired off:
if($($this.context).find('img').hasClass('scheduler-img')) {
url = window.location.origin + "/recipes/" + planned_recipe_id +'/update_recipe'
} else {
url = window.location.origin + "/recipes/" + recipe_id +'/make_recipe'
success = successfulRecipeAdd(closest_date, image_url, recipe_id);
}
$.ajax({
url: url,
method: 'GET',
dataType: 'json',
data: {
planned_for: planned_for,
meal_type: meal_type
},
success: (function() {
success
}),
error: (function(XMLHttpRequest, textStatus, errorThrown) {
alert("Status: " + textStatus); alert("Error: " + errorThrown);
})
});
I'm using this for a jQuery draggable and sortable table, so when I'm dragging and dropping the first item, it doesn't work because it tries creating the 'success' variable with an empty dataset. However, it does work for every subsequent drag/drop after.
function successfulRecipeAdd(closest_date, image_url, recipe_id) {
$.get( window.location.origin + "/recipes/get_recipes", function(data) {
console.log(data);
var planned_recipe_id = $(data).last()[0][0].id;
$(closest_date).append("<img src='"+image_url+"'class='scheduler-img col-md-12' id='"+ recipe_id +"' data-planned-id='"+planned_recipe_id+"'>");
});
}
I'm having a lot of trouble figuring out a way to write this that would allow me to create variables within the if/else statement, then fire off the ajax call using variables, rather than having two ajax calls within the if/else statement.

I'm making some functions after opening the modal. RefreshBirths() function needs motherId and fatherId which are from getDictionaryMother() and getDictionaryFather() functions (these render my mothers and father on page then I can get values in refreshBirths() function).
I checked that refreshBirths() takes my ids too early so a have undefined ids in the end.
I checked calling my refreshBirths() function in .done part in mother/father methods and it fixes my problem but I prefer do it explicitly in the indicated part of the code.
This doesn't fix but I want to make this there:
$('#create-modal').on('shown.bs.modal', function() {
refreshBreeds();
getDictionaryMother();
getDictionaryFather();
$.when(getDictionaryFather()).done(function() {
refreshBirths();
});
});
Here it fixes but I prefer have that method called in another place
function getDictionaryMother() {
$.ajax({
url: "/admin/api/dictionary/" + "ANIMAL_MOTHER",
type: "GET",
dataType: "json"
})
.done(function(response) {
$('#mother-create').empty();
$('#mother').empty();
response.forEach(function(mother){
$('#mother-create').append('<option value='+ mother.id +'> '+ mother.value +' </option>');
$('#mother').append('<option value='+ mother.id +'> '+ mother.value +' </option>');
});
refreshBirths();
})
.fail(function(jqxhr, textStatus, errorThrown) {
displayErrorInformation("Cannot get dict: " + name + " due to: " + jqxhr.responseText);
});
}
You can use .then() method on the Ajax request or .when().
I am attempting use a variable that I create through data being sent from php in one ajax function in a another ajax function. I'm not sure what I am doing wrong. I tried creating making this a global variable by doing var nameOutput and also tried var nameOutput = 0. You will see alert code in the second ajax function. This is outputting nothing. If I remove the .val(), I receive object Object.
The code in question is in the second Ajax function: data: {
'nameOutput': nameOutput.val()
}
Does anyone have any idea what I have to do?
var nameOutput;
$('#shuffle').on('click', function() {
$.ajax({
url: 'php/name-selection.php',
type: 'POST',
success: function(data) {
nameOutput = $('#name-output').html(data);
$(nameOutput).html();
},
complete:function(){
$('#send-info').slideDown(1500);
},
error: function(xhr, textStatus, errorThrown) {
alert(textStatus + '|' + errorThrown);
}
});
});
//var datastring1 = $('#name-output').serialize();
$('.check').click(function() {
alert(nameOutput.val());
$.ajax({
url: 'php/name-selection-send.php',
type: 'POST',
data: {
'nameOutput': nameOutput.val()
}
,
success: function(data) {
if (data == 'Error!') {
alert('Unable to submit inquiry!');
alert(data);
} else {
$('#success-sent').html(data);
}
},
complete:function(){
},
error: function(xhr, textStatus, errorThrown) {
alert(textStatus + '|' + errorThrown);
}
});
if you can set inner html of nameOutput using .html('blah') , so you can extract the html again using nameOutput.html() not nameOutput.val();
however I think you have to define the element like this to be a HTML element:
var nameOutput=$('<div></div>');
also in first ajax function,set the html using this:
nameOutput.html(data);
and if there is a real element with ID name-output , and you want the result to be visible, do both of these:
nameOutput.html(data);
$('#name-output').html(data);
I have a problem with jQuery calling an AJAX function, basically everytime a user changes a select box, I want it to call the getSubCategories function, but for some reason, nothing is happening. Any ideas?
If I load the page and add console.log inside the getSubCategories function it logs it, should that even be happening?
function getSubCategories() {
var id = $("#category").prop('selectedIndex');
var selectedCategory = $("#category").val();
//should change this into a response from AJAX and grab the slug from there, this is fine for now.
var slugOfCategory = convertToSlug(selectedCategory);
id++;
console.log('here');
$.ajax({
method: 'GET', // Type of response and matches what we said in the route
url: '/product/get_subcategories', // This is the url we gave in the route
data: {
'id': id
}, // a JSON object to send back
success: function(response) { // What to do if we succeed
$("#sub_category option").remove(); //Remove all the subcategory options
$.each(response, function() {
$("#sub_category").append('<option value="' + this.body + '">' + this.body + '</option>'); //add the sub categories to the options
});
$("#category_slug").attr('value', slugOfCategory);
},
error: function(jqXHR, textStatus, errorThrown) { // What to do if we fail
console.log(JSON.stringify(jqXHR));
console.log("AJAX error: " + textStatus + ' : ' + errorThrown);
}
});
}
function getCategories() {
var id = $("#type").prop('selectedIndex');
var selectedType = $("#type").val();
//should change this into a response from AJAX and grab the slug from there, this is fine for now.
var slugOfType = convertToSlug(selectedType);
console.log(slugOfType);
//add one to the ID because indexes dont start at 0 as the id on the model
id++;
$.ajax({
method: 'GET', // Type of response and matches what we said in the route
url: '/product/get_categories', // This is the url we gave in the route
data: {
'id': id
}, // a JSON object to send back
success: function(response) { // What to do if we succeed
$("#category option").remove(); //Remove all the subcategory options
$.each(response, function() {
$("#category").append('<option value="' + this.name + '">' + this.name + '</option>'); //add the sub categories to the options
});
$("#type_slug").attr('value', slugOfType);
},
error: function(jqXHR, textStatus, errorThrown) { // What to do if we fail
console.log(JSON.stringify(jqXHR));
console.log("AJAX error: " + textStatus + ' : ' + errorThrown);
}
});
}
function convertToSlug(Text) {
return Text
.toLowerCase()
.replace(/ /g, '_')
.replace(/[^\w-]+/g, '');
}
$(document).ready(function() {
var firstCatgegory = $("#category").val();
var slugOfFirstCategory = convertToSlug(firstCatgegory);
$("#category_slug").attr('value', slugOfFirstCategory);
var firstType = $("#type").val();
var slugOfFirstType = convertToSlug(firstType);
$("#type_slug").attr('value', slugOfFirstType);
$("#type").change(getCategories());
$("#category").change(getSubCategories());
});
Thanks for any help. (Sorry the code is a little messy, i've just been trying to get it to work so far)
This is due to the fact that the ajax call you are trying to make is asynchronous. When you call getSubCategories() it returns undefined which is why your code is not working.
To make this work you need to put your code within the success callback function instead.
<script>
function getSubCategories()
{
var id= $("#category").prop('selectedIndex');
$.ajax({
method: 'GET',
url: '/product/get_subcategories',
data: {'id' : id},
success: function(response){
// DO SOMETHING HERE
},
error: function(jqXHR, textStatus, errorThrown) { }
});
}
$( document ).ready(function() {
// This is also wrong. Currently you're passing
// whatever is returned from getSubCategories
// (which is undefined) as the callback function
// that the "change" event will call. This instead
// should be the reference to the function. Which
// in this case is getSubCategories
$("#category").change(getSubCategories);
});
Please put getCategories() and getSubCategories() Methods inside Change function like this.Sorry for not code formatting.
<script>
$(document).ready(function(){
$("#category").change(function(){
getSubCategories();
});
$("#type").change(function(){
getCategories();
});
});
</script>
I'm having problems with the return value of a jQuery ajax call. I can debug the whole thing server side and I know everything is working correctly and the return value is properly being calculated. I can look under the NET tab in FireBug and see that the response is:
{"d":false}
But when I test the value in the Success function of the ajax call, msg is NULL. Why?
Here's the ajax call:
function GetStateCertifiable(areaID) {
$.ajax({
url: "../WebServices/AoP.asmx/GetStateCertifiable",
data: '{"AreaID":"' + areaID + '"}',
dataType: 'json',
success: function (msg) {
alert(msg); // for debugging
if (msg)
$("#isCertified").slideDown("fast");
else
$("#isCertified").slideUp("fast");
},
error: function (msg) {
alert("An error occured. \nStatus: " + result.status
+ "\nStatus Text: " + result.statusText
+ "\nError Result: " + result);
},
complete: function () {
}
});
};
Other, similarly structured client-side calls work fine. This is a same-domain request.
try changing the name of the variable to something other than msg. I think that might be a message box or something similar. Try
function GetStateCertifiable(areaID) {
$.ajax({
url: "../WebServices/AoP.asmx/GetStateCertifiable",
data: '{"AreaID":"' + areaID + '"}',
dataType: 'json',
success: function (result) {
alert(result); // for debugging
if (result)
$("#isCertified").slideDown("fast");
else
$("#isCertified").slideUp("fast");
},
error: function (result) {
alert("An error occured. \nStatus: " + result.status
+ "\nStatus Text: " + result.statusText
+ "\nError Result: " + result);
},
complete: function () {
}
});
};
It turns out the problem was that my web service (../WebServices/AoP.asmx/GetStateCertifiable) returned a bool and from the post response, I know that was properly sent back to the client. Ajax, however, didn't like that. Once I changed the web service to return the strings "true" or "false", everything worked.
Does jQuery ajax only work for strings or is there something I should have done to prepare the msg object to receive a bool?
I have a problem synchronizing calls using Rest Api and JavaScript Object Model.
I'm currently working with Client Side Rendering to customize a view for a Document Library and add some functionalities in this custom UI.
I have a small collection of id's, and I'm looping through this collection and make some ajax calls with each of this items.
The results of this operation is to perform some tasks and to update my UI when all these operations are completed to refresh my UI and display some icons.
What I expect is to have 3 icons displayed only for my three first items.
The problem is that sometimes it displays all the icons, sometimes the two first... randomly.
I know that there is some problems with the synchronization of my executeQueryAsync calls, I've learned about jQuery Deferred object, I've tried to use them but without results.
Below you'll find screenshots of what I expect.
Expected :

What would be the good way of using deferred ? Could anyone help ?
Thanks a lot

This is my main function for overriding the display :
(function () {
var accordionContext = {};
accordionContext.Templates = {};
// Be careful when add the header for the template, because it's will break the default list view render
accordionContext.Templates.Item = itemTemplate;
// Add OnPostRender event handler to add accordion click events and style
accordionContext.OnPreRender = [];
accordionContext.OnPreRender.push(function () {
$(function () {
IsCurrentUserMemberOfGroup("TEST Owners");
**$.when(IsUserApprover(arrayOfIDS).done(function () {
displayIcons();
}));**
});
});
accordionContext.OnPostRender = [];
accordionContext.OnPostRender.push(function () {
$(function () {
accordionOnPostRender();
fixColumns();
audit.relativeUrl = _spPageContextInfo.webAbsoluteUrl;

Starting with Gecko 30.0 (Firefox 30.0 / Thunderbird 30.0 / SeaMonkey 2.27), synchronous requests on the main thread have been deprecated due to the negative effects to the user experience.
You should avoid synchronous ajax calls...
I had the same problem and solved by adding an id during the custom rendering of the fields (items), on the postrender call my service asynchronously and according the result edit the OnPreRender page using the previously added ids.
I also did some hacks...e.g overriding the standard function RenderItemTemplate. Yes I know, it's not very clean but it works like a charm.
