I have an issue related to database. I am currently working with Gupshup bot programming. There are two different data persistence modes which can be read here and here. In the advanced data persistence, the following code is documented to put data into data base:
function MessageHandler(context, event) {
if(event.message=='update bug - 1452') {
jiraUpdate(context);
}
}
function jiraUpdate(context){
//connect to Jira and check for latest update and values
if(true){
context.simpledb.doPut("1452" ,"{\"status\":\"QA pending\",\"lastUpdated\":\"06\/05\/2016\",\"userName\":\"John\",\"comment\":\"Dependent on builds team to provide right build\"}");
} else{
context.sendResponse('No new updates');
}
}
function DbPutHandler(context, event) {
context.sendResponse("New update in the bug, type in the bug id to see the update");
}
If I want to change only one of column (say status or last Updated) in the table for the row with key value 1452, I am unable to do that. How can that be done?
I used the following code:
function MessageHandler(context, event) {
// var nlpToken = "xxxxxxxxxxxxxxxxxxxxxxx";//Your API.ai token
// context.sendResponse(JSON.stringify(event));
if(event.message=='deposit') {
context.sendResponse("Enter the amount to be deposited");
}
if(event.message=="1000") {
jiraUpdate(context);
}
if(event.message== "show"){
context.simpledb.doGet("1452");
}
}
function HttpResponseHandler(context, event) {
var dateJson = JSON.parse(event.getresp);
var date = dateJson.date;
context.sendResponse("Today's date is : "+date+":-)");
}
function jiraUpdate(context){
//connect to Jira and check for latest update and values
if(true){
context.simpledb.doPut("aaa" ,"{\"account_number\":\"90400\",\"balance\":\"5800\"}");
} else{
context.sendResponse('No new updates');
}
}
/** Functions declared below are required **/
function EventHandler(context, event) {
if (!context.simpledb.botleveldata.numinstance)
context.simpledb.botleveldata.numinstance = 0;
numinstances = parseInt(context.simpledb.botleveldata.numinstance) + 1;
context.simpledb.botleveldata.numinstance = numinstances;
context.sendResponse("Thanks for adding me. You are:" + numinstances);
}
function DbGetHandler(context, event) {
var bugObj = JSON.parse(event.dbval);
var bal = bugObj.balance;
var acc = bugObj.account_number;
context.sendResponse(bal);
var a = parseInt (bal,10);
var b = a +1000;
var num = b.toString();
context.simpledb.doPut.aaa.balance = num;
}
function DbPutHandler(context, event) {
context.sendResponse("testdbput keyword was last put by:" + event.dbval);
}
Since the hosted DB that is provided by Gupshup is the DynamoDB of AWS. Hence you can enter something as a key, value pair.
Hence you will have to set the right key while using doPut method to store data into the database and use the same key to get the data from the database using the doGet method.
To update the data you should first call doGet method and then update the JSON with right data and then call doPut method to update the database with the latest data.
I have also added something which is not present in the documentation, You can now make DB calls and choose which function the response goes to.
I am refactoring your example as using 3 keywords and hard coding few things just for example -
have - this will update the database with these values
{"account_number":"90400","balance":"5800"}
deposit - on this, the code will add 1000 to the balance
show - on this, the code show the balance to the user.
Code -
function MessageHandler(context, event) {
if(event.message=='have') {
var data = {"account_number":"90400","balance":"5800"};
context.simpledb.doPut(event.sender,JSON.stringify(data),insertData); //using event.sender to keep the key unique
return;
}
if(event.message=="deposit") {
context.simpledb.doGet(event.sender, updateData);
return;
}
if(event.message== "show"){
context.simpledb.doGet(event.sender);
return;
}
}
function insertData(context){
context.sendResponse("I have your data now. To update just say \"deposit\"");
}
function updateData(context,event){
var bugObj = JSON.parse(event.dbval);
var bal = bugObj.balance;
var a = parseInt(bal,10);
var b = a + 1000;
var num = b.toString();
bugObj.balance = num;
context.simpledb.doPut(event.sender,bugObj);
}
function EventHandler(context, event) {
if (!context.simpledb.botleveldata.numinstance)
context.simpledb.botleveldata.numinstance = 0;
numinstances = parseInt(context.simpledb.botleveldata.numinstance) + 1;
context.simpledb.botleveldata.numinstance = numinstances;
context.sendResponse("Thanks for adding me. You are:" + numinstances);
}
function DbGetHandler(context, event) {
var accountObj = JSON.parse(event.dbval);
context.sendResponse(accountObj);
}
function DbPutHandler(context, event) {
context.sendResponse("I have updated your data. Just say \"show\" to view the data.");
}

I want to execute this query
select * from properties where propertyCode IN ("field1", "field2", "field3")
How can I achieve this in IndexedDB
I tried this thing
getData : function (indexName, params, objectStoreName) {
var defer = $q.defer(),
db, transaction, index, cursorRequest, request, objectStore, resultSet, dataList = [];
request = indexedDB.open('test');
request.onsuccess = function (event) {
db = request.result;
transaction = db.transaction(objectStoreName);
objectStore = transaction.objectStore(objectStoreName);
index = objectStore.index(indexName);
cursorRequest = index.openCursor(IDBKeyRange.only(params));
cursorRequest.onsuccess = function () {
resultSet = cursorRequest.result;
if(resultSet){
dataList.push(resultSet.value);
resultSet.continue();
}
else{
console.log(dataList);
defer.resolve(dataList);
}
};
cursorRequest.onerror = function (event) {
console.log('Error while opening cursor');
}
}
request.onerror = function (event) {
console.log('Not able to get access to DB in executeQuery');
}
return defer.promise;
But didn't worked. I tried google but couldn't find exact answer.
If you consider that IN is essentially equivalent to field1 == propertyCode OR field2 == propertyCode, then you could say that IN is just another way of using OR.
IndexedDB cannot do OR (unions) from a single request.
Generally, your only recourse is to do separate requests, then merge them in memory. Generally, this will not have great performance. If you are dealing with a lot of objects, you might want to consider giving up altogether on this approach and thinking of how to avoid such an approach.
Another approach is to iterate over all objects in memory, and then filter those that don't meet your conditions. Again, terrible performance.
Here is a gimmicky hack that might give you decent performance, but it requires some extra work and a tiny bit of storage overhead:
Store an extra field in your objects. For example, plan to use a property named hasPropertyCodeX.
Whenever any of the 3 properties are true (has the right code), set the field (as in, just make it a property of the object, its value is irrelevant).
When none of the 3 properties are true, delete the property from the object.
Whenever the object is modified, update the derived property (set or unset it as appropriate).
Create an index on this derived property in indexedDB.
Open a cursor over the index. Only objects with a property present will appear in the cursor results.
Example for 3rd approach
var request = indexedDB.open(...);
request.onupgradeneeded = upgrade;
function upgrade(event) {
var db = event.target.result;
var store = db.createObjectStore('store', ...);
// Create another index for the special property
var index = store.createIndex('hasPropCodeX', 'hasPropCodeX');
}
function putThing(db, thing) {
// Before storing the thing, secretly update the hasPropCodeX value
// which is derived from the thing's other properties
if(thing.field1 === 'propCode' || thing.field2 === 'propCode' ||
thing.field3 === 'propCode') {
thing.hasPropCodeX = 1;
} else {
delete thing.hasPropCodeX;
}
var tx = db.transaction('store', 'readwrite');
var store = tx.objectStore('store');
store.put(thing);
}
function getThingsWherePropCodeXInAnyof3Fields(db, callback) {
var things = [];
var tx = db.transaction('store');
var store = tx.objectStore('store');
var index = store.index('hasPropCodeX');
var request = index.openCursor();
request.onsuccess = function(event) {
var cursor = event.target.result;
if(cursor) {
var thing = cursor.value;
things.push(thing);
cursor.continue();
} else {
callback(things);
}
};
request.onerror = function(event) {
console.error(event.target.error);
callback(things);
};
}
// Now that you have an api, here is some example calling code
// Not bothering to promisify it
function getData() {
var request = indexedDB.open(...);
request.onsuccess = function(event) {
var db = event.target.result;
getThingsWherePropCodeXInAnyof3Fields(db, function(things) {
console.log('Got %s things', things.length);
for(let thing of things) {
console.log('Thing', thing);
}
});
};

Hello I am currently using a script that takes your table data and saves it in local storage where I call it in another js file.
I have a script that succesfully can save the table data exactly how I would like, But I have been struggling on how to implement a count for how many table rows there are in the table before the data is saved in local storage.
Here is what I have tried:
$(function() {
loadAllTasks();
$("#addTask").click(function() {
let cells = Array.prototype.map.call($("#items-table")[0].rows, row => {
return Array.prototype.map.call(row.cells, cell => cell.innerHTML);
});
var task = {
cells: cells
};
task.Name = $("#taskName").val();
var itemCount = $("#items-table tr").length - 1;
var count = {
itemCount: itemCount
};
saveTaskInStorage(task);
saveCountInStorage(count);
});
function saveTaskInStorage(task) {
var savedTasks = JSON.parse(localStorage.getItem('tasks'));
if (!savedTasks || typeof(savedTasks) !== "object")
savedTasks = {};
savedTasks[task.Name] = task;
localStorage.setItem('tasks', JSON.stringify(savedTasks));
alert("Task has been Added");
}
function saveCountInStorage(count) {
var savedCount = localStorage.getItem('counts')
savedCount = {};
savedCount[task.Name] = count;
localStorage.setItem('counts', savedCount);
}
function loadCountFromStorage1(taskName) {
var savedCount = localStorage.getItem('counts');
return savedCount[taskName];
}
function loadAllTasks() {
var savedTasks = JSON.parse(localStorage.getItem('tasks'));
if (!savedTasks || typeof(savedTasks) !== "object")
return;
for (var taskName in savedTasks) {
$("#loadTask").append('<option>' + taskName + '</option>')
}
}
});
function loadTaskFromStorage1(taskName) {
var savedTasks = JSON.parse(localStorage.getItem('tasks'));
return savedTasks[taskName];
}
then in the other js file I call these functions:
function loadAllTasks() {
// Get all saved tasks from storage and parse json string to javascript object
var savedTasks = JSON.parse(localStorage.getItem('tasks'));
// To be sure that object exists on localStorage
if (!savedTasks || typeof (savedTasks) !== "object")
return;
// Get all property name of savedTasks object (here it means task names)
for (var taskName in savedTasks){
$("#select-task").append('<option>' + taskName + '</option>')
}
}
function loadTaskFromStorage(taskName) {
var savedTasks = JSON.parse(localStorage.getItem('tasks'));
// Return the task by its name (property name on savedTasks object)
return savedTasks[taskName];
}
function loadCountFromStorage(taskName) {
var savedCount = localStorage.getItem('counts');
return savedCount[taskName];
}
loadAllTasks();
var task = loadTaskFromStorage($("#select-task").val());
then I just do:
alert(task.cells);
this works perfectly, it alerts all the custom saved data in the table that I saved.
I then have tried a bunch of different options for this:
alert(task.itemCount);
and a bunch of variations of that.
I want to be able to do:
alert(task.count);
this then will alert me the number of rows in the table of the saved task I currently have selected in my select html.
I also tried getting rid of the saveCount functions and just modifing this:
var task = {
cells: cells,
count: count
};
but unfortunately this also does not work.
I would really appreciate it if anyone could help me on how I would save the table row count in local storage and be able to call it on each different saved task in the select on my html/ js file.
each saved task will have a different count so I want to do task.count
Thanks for the Help <3!
You should really look into using a front end framework like React or Angular. You are looping through dom elements and saving its inner html as values in your task when what you really need is something data driven. However, I think this might solve your issue.
In your click handler for #addTask you have
let cells = Array.prototype.map.call($("#items-table")[0].rows, row => {
return Array.prototype.map.call(row.cells, cell => cell.innerHTML);
});
var task = {
cells: cells
};
Try adding in a counter here
let count = 0;
let cells = Array.prototype.map.call($("#items-table")[0].rows, row => {
count += 1;
return Array.prototype.map.call(row.cells, cell => cell.innerHTML);
});
var task = {
cells: cells
count: count
};
Hopefully that works for you
I'm trying to write a javascript on CRM Phone Call page. We have a custom look-up field called new_department, and we want to automatically populate the field with value "IT" (there should be one) when the form is opened.
The thing is we have a separate Dev and Production CRM link therefore I cannot just assign a hard-coded GUID value into this field. So first I wrote a Rest Retrieve Multiple to get the correct department.
Then my problem is I'm not sure about the result returned from this Retrieve Multiple. How do I grab just the GUID from Rest? I'm seeing that this is a type of {Object}. Then lastly how do I go about setting the lookup value after retrieving the {Object}? Any help is greatly appreciated.
Here is my code.
function phonecall() {
var formType = Xrm.Page.ui.getFormType();
if (formType == 1) //create
{
//RetrieveMultiple function
var DepartmentId = getITDepartment();
//set the lookup value
var ID = DepartmentId.id;
var departmentValue = new Array();
departmentValue[0] = new Object();
departmentValue[0].id = DepartmentId;
departmentValue[0].name = 'IT';
userValue[0].entityType = "new_department";
Xrm.Page.getAttribute("new_department").setValue(departmentValue);
}
}
function getITDepartment()
{
XrmServiceToolkit.Rest.RetrieveMultiple("new_departmentSet", "$select=new_departmentId&$filter=new_name eq 'IT'",
function (results) {
if (results.length > 0)
resultList = results;
}, function (error) { alert(error); }, function onComplete() { }, false);
return resultList;
}
Thanks much.
I'm not familiar with XrmServiceToolkit but here how code could look like to work properly - I replaced only assigning part:
var DepartmentId = getITDepartment();
if (DepartmentId != null && DepartmentId.length > 0){
Xrm.Page.getAttribute("new_department").setValue([{
id: DepartmentId[0].new_departmentId,
name: "IT",
entityType: "new_department"
}]);
}
You are setting the lookup value correctly, you just need to get the Id correctly. The results variable is an array of new_department records, so try something like this:
var resultId = null;
XrmServiceToolkit.Rest.RetrieveMultiple("new_departmentSet", "$select=new_departmentId&$filter=new_name eq 'IT'",
function (results) {
if (results.length > 0)
resultId = results[0].new_departmentId; //gets the first record's Id
}, function (error) { alert(error); }, function onComplete() { }, false);
return resultId;
I have a bug in my code that only saves the last object in an array upon reload. I have a feeling that my addAccount() function is not saving or inserting data correctly. Everything else works correctly. In my console, it shows that the data is being inserted into the array, but when I refresh I only get the last object saved.
I'm not sure what to do.
// The list of accounts array.
var accountsArray = [];
function addAccount() {
// Take fields and put user data into varables.
var accountName = document.getElementById('accountName').value;
var accountBalance = document.getElementById('accountBalance').value;
var accountType = document.getElementById("accountType");
var accountTypeSelected = accountType.options[accountType.selectedIndex].text;
var accountCurrency = document.getElementById("accountCurrency");
var accountCurrencySelected = accountCurrency.options[accountCurrency.selectedIndex].text;
var temporaryObject = {
'accountName': accountName,
'accountBalance': accountBalance,
'accountTypeSelected': accountTypeSelected,
'accountCurrencySelected': accountCurrencySelected
};
accountsArray.push(temporaryObject);
console.log(accountsArray);
saveAccountData();
showAccountsArray();
}
function saveAccountData() {
localStorage.setItem('accountsArray', JSON.stringify(accountsArray));
}
function showAccountsArray() {
//var accountsLocalStorage = JSON.parse(localStorage['accountsArray']);
if (localStorage.getItem("accountsArray") === null) {
document.getElementById("getStarted").style.visibility="visible";
document.getElementById("balanceToolbarName").style.visibility="hidden";
document.getElementById("accountsMainList").style.visibility="hidden";
} else {
var accountsLocalStorage = JSON.parse(localStorage['accountsArray']);
console.log(accountsLocalStorage);
var accountInfo = '';
var i = 0;
while (i < accountsLocalStorage.length) {
accountInfo += '<li class="swipeout"><div class="swipeout-content item-content"><div class="item-inner"><div class="item-title">' + accountsLocalStorage[i].accountName + '</div><div class="item-after">$' + accountsLocalStorage[i].accountBalance + '</div></div></div><div class="swipeout-actions-left"><a href="#" class="action1">Clear</div><div class="swipeout-actions-right">Delete</div></a></li>';
document.getElementById("accountsList").innerHTML = accountInfo;
i++;
}
document.getElementById("getStarted").style.visibility="hidden";
document.getElementById("balanceToolbarName").style.visibility="visible";
document.getElementById("accountsMainList").style.visibility="visible";
}
}

all of your functions work correctly as tested by the link you've provided. When the page loads it successfully retrieves the data (if any) from the local storage and displays on the page. However, the global array variable accountsArray is populated with data retrieved from the local storage.
You need to repopulate the global array otherwise when you call saveAccountData it will save whatever the array holds which indeed overrides whatever you had in the local storage. To fix it, simply add add this code block...
$(function(){
var data = localStorage.getItem("accountsArray");
if(data != null)
accountsArray = JSON.parse(localStorage.getItem("accountsArray"));
});
I m creating mobile web application using html5 and javascript.I m having two javascript files. AttributesDatabase.js and AttributeView.js.From AttributeView.js i m calling one function from AttributeDatabase.js in that i m executing one select query.Now the query result should go to AtttributeView.js.But the Websql transaction is asynchronous call that is what it is not returning proper result.Is there any way to handle the websql result.
Please help if any way there?
Edited
AttributeView.js
var AttributeDAOObj = new AttributeDAO();
AttributeDAOObj.GetAttributeList();
alert(AttributeDAOObj.GetAttributeList()); //This alert is coming as undefined.
AttributeDAO.js
this.GetAttributeList = function () {
var baseDAOObj = new BaseDAO();
var query = "SELECT AttributeName FROM LOGS";
// this.Successcalbackfromsrc = this.myInstance.Successcalback;
var parm = { 'query': query, 'Successcalback': this.myInstance.Successcalback };
baseDAOObj.executeSql(parm);
}
//To Create database and execute sql queries.
function BaseDAO() {
this.myInstance = this;
//Creating database
this.GetMobileWebDB = function () {
if (dbName == null) {
var dbName = 'ABC';
}
var objMobileWebDB = window.openDatabase(dbName, "1.0", dbName, 5 * 1024 * 1024);
return objMobileWebDB;
}
//Executing queries and getting result
this.executeSql = function (query) {
var objMobileWebDB = this.myInstance.GetMobileWebDB();
objMobileWebDB.transaction(function (transaction) {
//In this transaction i m returning the result.The result value is coming.
transaction.executeSql(query, [], function (transaction, result) { return result; }, this.Errorclback);
});
}
}
The problem is in you succes call back (like in the comment to your question, stated by DCoder)
function (transaction, result) { return result; }
this is returning where to?
So this is how to do it (or at least one way)
you can do for example:
function (transaction,result){
console.log("yes, I have some result, but this doesn't say anything, empty result gives also a result");
// so check if there is a result:
if (result != null && result.rows != null) {
if (result.rows.length == 0) {
// do something if there is no result
}else{
for ( var i = 0; i < result.rows.length; i++) {
var row = result.rows.item(i);
var id = result.rows.item(i).id; //supposing there is an id in your result
console.log('Yeah! row id = '+id);
}
}
}else{
// do something if there is no result
}
};
note the code above can be compacter, but this is how to understand it better.
another way is to put this function is a seperate piece of code, so you keep the sql statement more compact and readable. Like you call you error callback this can be in your function (with this. in front of it) or a completely seperate function.
