I have one array of data and I want to bind that data to multicombobox.
I have binded that data to Multicombobox using javascript as shown below.
The problem is when I select any value from multicombobox, tokens are not displaying as per the default behavior of the control.
Please help me in this. As per my guess, this array is not associative array (do not have keys and values.) this might have caused this issue.
Below is the code:
var data = sap.ui.getCore().getModel("myModel").getData();
var oModel = new sap.ui.model.json.JSONModel();
oModel.setData(data);
this.getView().setModel(oModel, "myModel");
var fruitsArray = data.fruits[0].names;
for(var i = 0; i<fruitsArray.length; i++){
var fruitsDD;
if(!fruitsDD){
fruitsDD = this.getView().byId("MCBId");
}
var oCoreItem = new sap.ui.core.Item();
oCoreItem.setText(fruitsArray[i]);
oCoreItem.setKey(fruitsArray[i]);
fruitsDD.addItem(oCoreItem);
}
{
"A":"Apple",
"B":[
{
"key":1,
"value":"ball",
"fruits":[
"Apple",
"Orange",
"banana",
"Guava"
]
}
]
}
XML view:
<MultiComboBox id="MCBId" width="280px" class="sapUiTinyMarginTop" ></MultiComboBox>

I am working on a chrome plugin that fetches data. But now i have been running into a problem, I have been asked to put together a nested array with all the data I have retrieved but I have no clue on how to pull this off.
What i want to create:
var messagedata [{
time: messageTime,
Date: messageDate,
Text: messageText
{
time: messageTime,
Date: messageDate,
Text: messageText
}
}];
Note that I know how to create the above when I have the variables. That is not the problem. But in this case i do not know how to declare the variables for each message from the array that is generated.
What i need is a nested array for each message that is in the HTML. So the above example displays 2 arrays but it could be 54 for example.
Code i use to generate normal array:
adiv.innerHTML = cleanupDocString;
trs = adiv.querySelectorAll('tr[bgcolor="#FFFFFF"]');
trs.forEach(function(tr) {
var d = [];
tr.querySelectorAll("td")
.forEach(function(td) {
var img = td.querySelector("img"),
src = img && img.attributes.getNamedItem("src").value;
d.push(src || td.textContent);
});
msgs.push(d);
});
The code above puts this out in console (this example has 2 messages inside it, there are also arrays with 54 messages):
0:Array(6)
0:"2017-08-31T00:00:00"
1:"13:22"
2:"MessageType"
3:”ClientName"
4:"Subject "
5:"messageText"
length:6
proto:Array(0)
1:Array(6)
0:"2017-08-31T00:00:00"
1:"13:21"
2:" MessageType "
3: "ClientName"
4:" Subject "
5:" messageText "
lenth:6
proto:Array(0)
To make the question easier:
I need to know how i can put the data into a variable that i fetch from the array above. I just don't know how to do it so its dynamic.
What i tried:
var messageDate = msgs[0][0];
var messageTime = msgs[0][1];
var messageType = msgs[0][2];
var messageClient = msgs[0][3];
var messageSubject = msgs[0][4];
var messageText = msgs[0][5];
The above code works but only fetches the first message. I need all the messages that are on the page that is provided. I tried using a ID in the first [] but that also didn't give me the desired result.
Thanks for your help and patience in advance.
Output and code has been slightly edited so it hides personal information
i am assuming msgs is arrray of arrays and the order of properties is guaranteed
var mappedArray = msgs.map((msg)=> {
return {
messageDate : msg[0];
messageTime : msg[1];
messageType : msg[2];
messageClient : msg[3];
messageSubject : msg[4];
messageText :msg[5];
}
})
Edit1
you can use arrayconcat
var mergedArray = mappedArray.concat(otherArray);
To transform the multidimensional array to an array of objects with the help of Array.prototype.map and a simple helper dictionary which defines the index => property mapping.
var messages = [
[
"2017-08-31T00:00:00",
"13:22",
"MessageType",
"ClientName",
"Subject",
"messageText",
"unwanted value"
],
[
"2017-08-31T00:00:00",
"13:22",
"MessageType",
"ClientName",
"Subject",
"messageText",
"unwanted value"
],
[
"2017-08-31T00:00:00",
"13:22",
"MessageType",
"ClientName",
"Subject",
"messageText",
"unwanted value"
]
];
var mappingDef = {
0: 'messageDate',
1: 'messageTime',
2: 'messageType',
3: 'messageClient',
4: 'messageSubject',
5: 'messageText'
};
function transformMessages(messages, mappingDef) {
return messages.map(function(message) {
var obj = {};
for(var index in mappingDef) {
if(mappingDef.hasOwnProperty(index)) {
obj[mappingDef[index]] = message[index];
}
}
return obj;
});
}
console.log(transformMessages(messages, mappingDef));
I have data coming in from the db I need to store in a js array of objects. How do I initialize this js array of objects , so that I can keep adding the data when I get it from the db .
The object structure will be of this format
var OsNames = [{deviceName:"TV",
releases: [
{release: "rel1", hws : [{hw:"h1"},{hw:"h2"},{hw:"h3"}]},
{release: "rel2", hws: [{hw:"h1"},{hw:"h2"},{hw:"h3"}]}
]},
{deviceName:"Phone",
releases: [
{release: "rel1", hws: [{hw:"h1"},{hw:"h2"},{hw:"h3"}]},
{release: "rel2", hws: [{hw:"h1"},{hw:"h2"},{hw:"h3"}]}]
}];
var OsNames = [];
You can add data to Array by pushing elements in it when you get it from the db
e.g.
OsNames.push({release: "rel1", hws : [{hw:"h1"},{hw:"h2"},{hw:"h3"});
I think that is what you are looking for.
var osNames = [];
// Get Data from Database
var myData = ajax.get(...);
for (var i=0; i < myData.length; i++) {
osNames.push(myData[i]);
}
I need to store (many) objects or arrays of data, which need to have the following criteria:
I need to be able to add a new set of data into the existing data easily
I need to be able to sort the data by date/ time added easily (array in order of when entries were pushed to it)
I need to be able to grab an entry easily using a reference, either integer or string. This is important, at the moment I have to do an $.each() to loop through my data until I find the entry I want.
I have tried using a structure like:
saved_info = {
1001: {//all my data for ref 1001},
1002: {//all my data for ref 1002}
}
which gave me what wanted of being able to grab the info easily given a reference:
info = saved_info[1001];
however, the reference numbers I use aren't in order - I use a reference given to me (its a unique identifier), therefore the object isn't in order of when items were added/saved/pushed.
You can use two objects:
One that stores the data by key
Another that stores the sort order
This way you can (i) lookup an element by key (ii) loop over elements in the order they were inserted. Rough outline of the structure:
var DataObject = {
data: {},
sort: []
};
Here is how you add data to this structure:
DataObject.data[1004] = {name: "Test 4"};
DataObject.sort.push(1004);
DataObject.data[1001] = {name: "Test 1"};
DataObject.sort.push(1001);
DataObject.data[1003] = {name: "Test 3"};
DataObject.sort.push(1003);
DataObject.data[1002] = {name: "Test 2"};
DataObject.sort.push(1002);
Here is how you perform a random access:
console.log(DataObject.data[1001].name);
console.log(DataObject.data[1003].name);
And here is how you iterate over all elements in the order they were added:
var i;
for (i = 0; i < DataObject.sort.length; i++) {
console.log(DataObject.data[DataObject.sort[i]].name);
}
It is possible to wrap the entire logic inside a class:
function DataObject() {
this.data = {};
this.sort = [];
this.setItem = function (k, v) {
this.data[k] = v;
this.sort.push(k);
};
this.getItemByKey = function (k) {
return this.data[k];
};
this.getItemByPos = function (i) {
return this.data[this.sort[i]];
};
this.getAllItems = function () {
var i, r = [];
for (i = 0; i < this.sort.length; i++) {
r.push(this.data[this.sort[i]]);
}
return r;
};
}
var t = new DataObject();
t.setItem(1001, {name: "Test 1"});
t.setItem(1002, {name: "Test 2"});
t.setItem(1003, {name: "Test 3"});
t.setItem(1004, {name: "Test 4"});
console.log(t.getItemByKey(1001));
console.log(t.getItemByPos(0));
console.log(t.getAllItems());
Try to build a Json like this,
var xJson = {
"1001":{//all my data for ref 1001},
"1002":{//all my data for ref 1002}
};
and you can fetch the records as per your wish using the bracket notation, since we are using a numeric value as a key.
var xData = xJson["1001"];
I am trying to set up an associative array for the following data:
name date alpha beta
Andrew 12/08/07 2.3 1.4
5/12/07
26/03/08
____________________________________
Fred 3/09/07 2.1 1.1
23/01/08
____________________________________
Basically, each patient would have a name and alpha , beta value but multiple dates on which they visited doctor. I was thinking of something like following where name is the primary key and dates are stored in an array and alpha, beta is a float value associated with the key.
var info = [{ name: [{ dates: [ ], alpha: float, beta: float }] }];
and then this info array would be populated on reading the csv file. What would be the right format for initialising such an associative array? or what other data structure would be a good approach for representing such a data?
Thanks in advance!
Edit: Since each patient has a unique name, instead of using an array, you should consider using a single object where each patient is an object identified by the object key, for example:
var patientList = {
andy: {},
bob: {}
};
To get your data from your CSV file into this structure you might consider something like this:
var csv = 'Andrew\t12/08/07\t1.2\t3.4\nAndrew\t15/09/08\t1.2\t3.4\nAndrew\t14/08/07\t1.2\t3.4\t\nBob\t18/09/08\t1.2\t3.4\nAndrew\t21/08/07\t1.2\t3.4\nDavid\t31/09/08\t1.2\t3.4\nAndrew\t22/08/07\t1.2\t3.4\t\nSam\t26/09/08\t1.2\t3.4';
// Split the CSV file at the carriage return.
var data = csv.split('\n');
// Recursive over the data with `map`, splitting each line up
// on the tabs and returning a patient object for each.
data = data.map(function (el) {
var patient = el.split('\t');
return {
name: patient[0],
date: patient[1],
alpha: patient[2],
beta: patient[3]
}
});
function getListOfPatientNames(arr) {
var newarr = [];
// For each patient object return the patient name only
newarr = arr.map(function (patient) {
return patient.name;
});
// A quick way of filtering out duplicates
return newarr.filter(function(elem, pos) {
return newarr.indexOf(elem) == pos;
});
}
// Return a unique list of names, and sort them.
var names = getListOfPatientNames(data).sort();
var patientList = {};
for (var i = 0, l = data.length; i < l; i++) {
var name = data[i].name;
// If the patient name doesn't exist in patientList yet
if (!patientList[name]) {
// Add a new patient object using the name as the key
var newPatient = {
dates: [data[i].date],
alpha: data[i].alpha,
beta: data[i].beta
};
patientList[name] = newPatient;
} else {
// If the patient already exists push the date to the dates array
patientList[name].dates.push(data[i].date);
}
}

The term "associative array" is almost never used wrt JavaScript; you use objects (sometimes called "maps" or "dictionaries") for name/value information, or arrays for ordered data.
It looks like you want an array of patient objects, like this:
var patients = [
{
name: "Andrew",
dates: [/*...the dates...*/],
alpha: 2.3,
beta: 1.4
},
{
name: "Fred",
dates: [/*...the dates...*/],
alpha: 2.1,
beta: 1.1
}
];
You might or might not want to use a constructor function to create those objects, depending on your needs, but with the simple data you've given there's probably no need.
I am new to Javascript (familiar with C/C++) and I am trying to parse out an XML file and store it in an Array of Objects. The structure is similar to a bullet list where there is one main List item and possibly multiple List subitems:
var MenuLine =
[{
label : "null",
icon : "null",
Subitem:
[{
label : "null",
icon : "null"
}]
}];
Which allows me to use the following syntax:
var someRandomSubitemText = MenuLine[2].Subitem[4].label;
I tried populating this array using the .push method:
var tempMenuLine = [];
var tempSubitem = [];
$(xml).find("item").each(function()
{
tempMenuLine.label = $(xml).children("label").text();
tempMenuLine.icon = $(xml).children("icon").text();
$(this).children("subitem").each(function()
{
tempSubitem.label = $(this).children("label").text();
tempSubitem.icon = $(this).children("icon").text();
tempMenuLine.Subitem.push(tempSubitem);
});
MenuLine.push(tempMenuLine);
});
However this does not work since the .push method passes a reference to tempMenuLine and I am overwriting tempMenuLine with each iteration. Is there a way that I could write directly to the MenuLine array using something similar to the following syntax?
$(xml).find("item").each(function(index1)
{
MenuLine[index1].label = $(xml).children("label").text();
MenuLine[index1].icon = $(xml).children("icon").text();
$(this).children("subitem").each(function(index2)
{
MenuLine[index1].Subitem[index2].label = $(this).children("label").text();
MenuLine[index1].Subitem[index2].icon = $(this).children("icon").text();
});
});
Move your temp var declarations inside of your loops:
$(xml).find("item").each(function() {
var tempMenuLine = [];
tempMenuLine[0].label = $(xml).children("label").text();
tempMenuLine[0].icon = $(xml).children("icon").text();
tempMenuLine[0].Subitem = []
$(this).children("subitem").each(function(){
var tempSubitem = [];
tempSubitem[0].label = $(this).children("label").text();
tempSubitem[0].icon = $(this).children("icon").text();
tempMenuLine[0].Subitem.push(tempSubitem);
});
MenuLine.push(tempMenuLine);
});
This way, you're initializing a new item for each iteration of the loops, removing the "link" it had to the previous item.
A recursive solution just for fun.
var MenuLine = Xml2Array(xmlText, 'item');
function Xml2Array(xmlDocument, itemName) {
if (!$(itemName, xmlDocument).length) {
return;
}
var tmpArray = [];
$(itemName, xmlDocument).each(function() {
tmpArray.push({
label: $('label', this).first().text(),
icon: $('icon', this).first().text(),
Subitem: Xml2Array(this, 'subitem')
});
});
return tmpArray;
}
