I'm trying to make a jquery plugin
but it's not working what a'm i doing wrong
(function($){
$.fn.rss({
//pass the options variable to the function
rss: function(options) {
//Set the default values, use comma to separate the settings, example:
var defaults = {
feedUrl: ''
}
var options = $.extend(defaults, options);
return this.each(function() {
var Setting = options;
//code to be inserted here
$.ajax({
type: "GET",
url: Setting.feedUrl,
dataType: "xml",
success: function(xml) {
$(xml).find('channel').each(function(){
$(xml).find('image').each(function(){
var title2 = $(this).find('title').text();
var url2 = $(this).find('link').text();
$('<div class="title"></div>').html(''+title2+'').fadeIn(1000).appendTo('#title');
});
$(xml).find('item').each(function(){
var title = $(this).find('title').text();
var brief = $(this).find('description').text();
var url = $(this).find('link').text();
$('<div class="items"></div>').html('<div class="dis">'+brief+'</div>').fadeIn(1000).appendTo('#blab');
});
});
}
});
});
}
});
})(jQuery)
By writing $.fn.rss(...), you're calling a non-existent function.
You need to create a function by writing
$.fn.rss = function(...) { ... };

I have this ajax call that populate the fields to a related field.
YAHOO.util.Event.onDOMReady(function() {
YAHOO.util.Event.addListener(
"parent_module_another_module_ida",
"change",
ajaxReq
);
function ajaxReq() {
var propertyId = $("#parent_module_another_module_ida").val();
if (propertyId != "") {
$.ajax({
url: "/?entryPoint=ajaxEntryPoint&module=Parent_Module&id=" + propertyId,
success: function(result) {
var res = JSON.parse(result);
$("#price").val(res['price']);
}
});
}
}
});
The fields gets auto populated but the format becomes something like 1000.000000 ive tried to modify the precision in its vardefs to 0 but its still the same i want to format the number if possible to something like this 1,000.
You will need to use toFixed function of javascript to get the required results.
Following is the modified code:
YAHOO.util.Event.onDOMReady(function() {
YAHOO.util.Event.addListener(
"parent_module_another_module_ida",
"change",
ajaxReq
);
function ajaxReq() {
var propertyId = $("#parent_module_another_module_ida").val();
if (propertyId != "") {
$.ajax({
url: "/?entryPoint=ajaxEntryPoint&module=Parent_Module&id=" + propertyId,
success: function(result) {
var res = JSON.parse(result);
price_val = res['price'].toFixed(0);
$("#price").val(price_val);
}
});
}
}
});
I am trying to upload a file using the FileUploader module in SAPUI5. The code I am trying to follow is from a blog https://blogs.sap.com/2016/11/08/step-by-step-on-how-to-use-the-sapui5-file-upload-feature/ however the code does not seem to execute the reader.onload function? It gets to reader.readAsDataURL(file) and dose not do anything? I am not sure where the problem lies and how to get it to work? Hekp will be much appreciated, there is a similar issue in the blog response but no help has been given.
XML
<u:FileUploader
id="VRCFileUploader"
value="{VRCFileUpload}"
placeholder="Please Attach document"
fileType="jpg,png,pdf"
style="Emphasized"
useMultipart="false" >
</u:FileUploader>
JS
function upload(evnt) {
var token;
var oView = this.getView();
var oFileUploader = this.byId("VRCFileUploader");
var sFileName = oFileUploader.getValue();
if (sFileName === "") {
sap.m.MessageToast.show("Please select a File to Upload");
return;
}
var file = jQuery.sap.domById(oFileUploader.getId() + "-fu").files[0];
var base64_marker = "data:" + file.type + ";base64,";
var reader = new FileReader();
//on load
reader.onLoad = (function(theFile){
return function(evt) {
//locate base64 content
var base64Index = evt.target.result.indexOf(base64_marker) + base64_marker.lenght;
// get base64 content
var base64 = evt.target.result.substring(base64Index);
var sTasksService = "SOME URL";
var sService2 = "SOME URL";
var oViewModel = oView.getModel();
var oContext = oView.getBindingContext();
var oTask = oViewModel.getProperty(oContext.getPath());
var oDataModel = sap.ui.getCore.getModel();
var sWorkitemId = JSON.stringify(oTask.wiId);
var service_url = sService2;
$.ajaxsetup({
cache: false
});
jQuery.ajax({
url: service_url,
asyn: false,
datatype: "json",
cache: false,
data: base64,
type: "post",
beforeSend: function(xhr) {
xhr.setRequestHeader("x-csrf-Token", token);
xhr.setRequestHeader("content-Type", file.type);
xhr.setRequestHeader("slug", sFileName);
xhr.setRequestHeader("WorkitemId", oTask.WiId);
},
success: function(odata) {
sap.m.MessageToast.show("file successfully uploaded");
oFileUploader.setValue("");
},
error: function(odata) {
sap.m.MessageToast.show("file Upload error");
}
});
};
})(file);
//Read file
reader.readAsDataURL(file);
}
In reply to Vortex:
Why is there an IIFE on the method being used on the onLoad Property?
Try to do somenthing like this:
reader.onload = event => {
let fileAsDataUrl = event.target.result;
....
};
I have created view model
var catalog = ko.observableArray();
$.ajax({
type: "GET",
url: "http://localhost:8080/ticket-service/rest/ticket/list",
success: function(msg) {
catalog.push.apply(catalog, $.map(msg, function(data) {
return new Ticket(data)
}));
return catalog;
},
error: function(msg) {
console.log(msg)
}
});
and the model
function Ticket(data) {
this.ticketId = ko.observable(data.ticketId);
this.ticketNo = ko.observable(data.ticketNo);
this.ticketTitle = ko.observable(data.ticketTitle);
this.longDescription = ko.observable(data.longDescription);
this.createdBy = ko.observable(data.createdBy);
this.createdOn= ko.observable(data.createdOn);
this.assignTo = ko.observable(data.assignTo);
this.priority = ko.observable(data.priority);
this.dueDate = ko.observable(data.dueDate);
this.status = ko.observable(data.status);
this.projectId = ko.observable(data.projectId);
}
with at the end viewmodel like this
return {
ticket: newTicket,
searchTerm: searchTerm,
catalog: filteredCatalog,
newTicket: newTicket,
addTicket: addTicket,
delTicket: delTicket
};
})();
console.log(vm);
ko.applyBindings(vm);
produce list,add, and delete form.The question is how can i use knockout mapping that can list from get methode.
you need to do something like this
Demonstrated taking a single entity from your code .
view:
Output Preview :
<pre data-bind="text:ko.toJSON($data,null,2)"></pre>
viewModel:
function Ticket(data) {
this.ticketId = ko.observable(data.ticketId);
}
var mapping = {
create: function (options) {
return new Ticket(options.data);
}
};
var ViewModel = function () {
var self = this;
self.catalog = ko.observableArray();
var data = [{
'ticketId': 1
}, {
'ticketId': 2
}]
//under ajax call do the same but pass 'msg' in place of data
self.catalog(ko.mapping.fromJS(data, mapping)())
console.log(self.catalog()); // check console for output
};
ko.applyBindings(new ViewModel());
sample working fiddle here
Heres the jsfiddle, jsfiddle.net/kqreJ
So I was using .bind no problem for this function but then I loaded more updates to the page and found out that .bind doesn't work for content imported to the page but just for content already on the page! Great!
So I switched it up to .delegate which is pretty cool but now I can't figure out how to .bind .unbind my function the way it was???
Function using .bind which worked perfect... except didn't work on ajax content.. :(
$('.open').bind("mouseup",function(event) {
var $this = $(this), handler = arguments.callee;
$this.unbind('mouseup', handler);
var id = $(this).attr("id");
var create = 'nope';
var regex = /\d+$/,
statusId = $('#maindiv .open').toArray().map(function(e){
return parseInt(e.id.match(regex));
});
var divsToCreate = [ parseInt(id) ];
$.each(divsToCreate, function(i,e)
{
if ( $.inArray(e, statusId) == -1 ) {
create = 'yup';
}
});
if( create == 'yup' ) {
if(id) {
$.ajax({
type: "POST",
url: "../includes/open.php",
data: "post="+ id,
cache: false,
success: function(html) {
$('.open').html(html);
$this.click(handler);
}
});
}
}
});
New function using .delegate that is not binded and creates multiple instances?
$('#maindiv').delegate("span.open", "mouseup",function(event) {
var $this = $(this), handler = arguments.callee;
$this.unbind('mouseup', handler);
var id = $(this).attr("id");
var create = 'nope';
var regex = /\d+$/,
statusId = $('#maindiv .open').toArray().map(function(e){
return parseInt(e.id.match(regex));
});
var divsToCreate = [ parseInt(id) ];
$.each(divsToCreate, function(i,e)
{
if ( $.inArray(e, statusId) == -1 ) {
create = 'yup';
}
});
if( create == 'yup' ) {
if(id) {
$.ajax({
type: "POST",
url: "../includes/open.php",
data: "post="+ id,
cache: false,
success: function(html) {
$('.open').html(html);
$this.click(handler);
}
});
}
}
});
I've spent hours trying to figure this out because I like learning how to do it myself but I had to break down and ask for help... getting frustrated!
I also read that when your binding and unbinding .delegate you have to put it above the ajax content? I've tried using .die() and .undelegate()... Maybe I just don't know where to place it?
Take a look at undelegate
It does to delegate what unbind does to bind.
In your case, I think it'd be something like:
$('#maindiv').undelegate("span.open", "mouseup").delegate("span.open", "mouseup" ...
Then you can drop the $this.unbind('mouseup', handler); within the function.
Firebug is giving me no error messages, but it's not working. The idea is regardless of whether the user picks an option from dropdown or if they type in something in search box, I want the alert() message defined below to alert what the value of the variable result is (e.g. {filter: Germany}). And it doesn't. I think the javascript breaks down right when a new Form instance is instantiated because I tried putting an alert in the Form variable and it was never triggered. Note that everything that pertains to this issue occurs when form.calculation() is called.
markup:
<fieldset>
<select name="filter" alter-data="dropFilter">
<option>Germany</option>
<option>Ukraine</option>
<option>Estonia</option>
</select>
<input type="text" alter-data="searchFilter" />
</fieldset>

Thank you for anyone who responds. I spent a lot of time trying to make this work.
The initial problem as to why the alert() was not being triggered when Form is instantiated is because, as you can see, the elements property belongs to the Form object, not fieldset object. And as you can see in the html, I place the fields as descendents of the fieldset object, not form.
