What I'm trying to do:
Figure out how to reference/grab geoJSON data from a server.
In this case I'm just using an example on the openLayers doc.
Ideally I'd just be able to print out a features ID/type, but I cannot get it to work.
What's happening:
var selectElement = document.getElementById('type');
var source = vector.getSource();
var feature = source.getFeatures()[0];
var changeInteraction = function() {
if (select !== null) {
map.removeInteraction(select);
}
var value = selectElement.value;
if (value == 'singleclick') {
select = selectSingleClick;
} else if (value == 'click') {
select = selectClick;
} else if (value == 'pointermove') {
select = selectPointerMove;
} else if (value == 'altclick') {
select = selectAltClick;
} else {
select = null;
}
if (select !== null) {
map.addInteraction(select);
select.on('select', function(e) {
document.getElementById('status').innerHTML = feature.getGeometry().getType();
});
console.log(feature);
}
};
I was hoping my innerHTML would display "Polygon" in this case, but no such luck. I've tried various combinations, and been looking over the documentation, can't see what I'm doing wrong.
The server I'm trying to grab the info from is,
https://openlayers.org/en/v4.6.4/examples/data/geojson/countries.geojson
Any help would be appreciated.
(I can attach full code if helpful)
I was able to replicate your program and find the solution for retrieving the Country's name for a selected feature, as mentioned in your comments.
First, remove the following lines. You don't want the first feature of the source file but the first selected feature instead.
var source = vector.getSource();
var feature = source.getFeatures()[0];
Second, define the feature inside the callback function(e) for the select Event. Also, since getFeatures() will return a Collection of features the getArray() method is necessary.
The get(key) method will return a value for a determined key, "name" in this case.
if (select !== null) {
map.addInteraction(select);
select.on('select', function(e) {
var feature = e.target.getFeatures().getArray()[0];
document.getElementById('status').innerHTML = ' ' +
feature.get("name") + ' ' + feature.getId();
});
}

I'm fairly new to CRM development and I'm trying to customize my account form to Capitalize any text field at onChange. I'm currently working with this function that I found online:
function UpperCaseField(fieldName)
{
var value = Xrm.Page.getAttribute(fieldName).getValue();
if (value != null)
{
Xrm.page,getAttribute(fieldName).setValue(value.toUpperCase());
}
}
However, when I change a value in my test account it tells me that the method getValue() is not supported. Everything I've found tells me to use getValue(). Im at a loss.
Any help would be appreciated.
Thanks
If you're getting a getValue is not supported error, double check that the value for fieldName is actually a field on the form. It's best to code more defensively, like this:
function UpperCaseField(fieldName)
{
var attr = Xrm.Page.getAttribute(fieldName);
if (!attr) {
console.log(fieldName + " not found");
return;
}
var value = attr.getValue();
if (value != null)
{
attr.setValue(value.toUpperCase());
}
}
Update: When you connect your fields to JS functions via the form editor, CRM passes an event context as the first parameter. Here's what the code would look like in that case:
function UpperCaseField(context)
{
var fieldName == context.getEventSource().getName();
var attr = Xrm.Page.getAttribute(fieldName);
if (!attr) {
console.log(fieldName + " not found");
return;
}
var value = attr.getValue();
if (value != null)
{
attr.setValue(value.toUpperCase());
}
}
Here's more info about the context: https://msdn.microsoft.com/en-us/library/gg328130.aspx
Replace line
Xrm.page,getAttribute(fieldName).setValue(value.toUpperCase());
with line
Xrm.Page.getAttribute(fieldName).setValue(value.toUpperCase());
Also please provide a screenshot that shows how you use/register this handler.
I'm getting the following error when attempting to get an enumerator for a collection of lists: "Uncaught Error: The collection has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested."
It happens on the line var listEnumerator = lists.getEnumerator(); it seems to me that there is an issue in my attempt to load lists into the client object with context.load(lists);
Here's the portion of my code that's causing the problem. I've marked the place just before the error is thrown.

I've looked at this question sharepoint javascript collection not initialized error which seems to be fairly similar to mine, but I'm having trouble implementing the solution provided there, making me think my error may be have a different cause.
I've also tried querying for the lists inside of the function that is throwing the error, but that doesn't seem to solve anything.
For a little background, these functions are attempting to read all lists from the app's host site, check to see if a specified list exists, and create a list if no matching list exists. If there's a better way of doing that than what I'm attempting, I'd be open to that too.
Any pointers?
Some things I've tried that don't seem to work:
Changing the Asynchronous query
context.executeQueryAsync(checkIfListExists(listToFind, hostweb, typeOfListToCreateIfTheListIsMissing), onQueryFailed);
to a Synchronous one.
context.executeQuery(checkIfListExists(listToFind, hostweb, typeOfListToCreateIfTheListIsMissing), onQueryFailed);
I've figured out an alternate, and shorter way to method of achieving the same goal I was trying to achieve before.
Instead of checking to see if a list does not already exist, I just try to create a list, and the Query fails to create a list if one is already there. (That's good because I don't want to overwrite the list if it is already there.)
I'm not totally sure if there are any undesired side effects of what I'm doing here, but in my tests it produced the desired behavior.
//____________________________Required function for accessing the host site's info.___________________________________
function getQueryStringParameter(param) {
var params = document.URL.split("?")[1].split("&");
for (var i = 0; i < params.length; i = i + 1) {
var singleParam = params[i].split("=");
if (singleParam[0] == param) {
return singleParam[1];
}
}
}
//____________________________Create a list if one does not already exist_________________________
function createList(listToCreate, typeOfList)
{

var hostUrl = decodeURIComponent(getQueryStringParameter("SPHostUrl"));
var hostContext = new SP.AppContextSite(currentContext, hostUrl);
var hostweb = hostContext.get_web();
var listCreationInfo = new SP.ListCreationInformation();
listCreationInfo.set_title(listToCreate);
if (typeOfList === "events")
{
listCreationInfo.set_templateType(SP.ListTemplateType.events);
}
else if (typeOfList === "contacts")

alert("We've created a list since one doesn't exist yet." );
}

I have a custom Dashboard page (Dashboard.aspx) that I made - it is not located inside the list, rather inside Pages folder.
I created this Dashboard to replace SharePoint's default "AllItems.aspx".
However, I could not replicate the onClick event of "Delete Item" from the SharePoint default list view.
Can anyone provide code snippets of how to delete a list item from a custom page?
P.S.: My custom page already has the ID and List Name. I appreciate your responses!
The function provided by Microsoft is this one:
function DeleteListItem() {
ULSrLq: ;
if (!IsContextSet()) return;
var b = currentCtx,
e = currentItemID,
g = currentItemFSObjType,
c = L_STSRecycleConfirm_Text;
if (!b.RecycleBinEnabled || b.ExternalDataList) c = L_STSDelConfirm_Text;
if (b.HasRelatedCascadeLists && b.CascadeDeleteWarningMessage != null) c = b.CascadeDeleteWarningMessage + c;
if (confirm(c)) {
var h = L_Notification_Delete,
f = addNotification(h, true),
a = b.clvp;
if (b.ExternalDataList && a != null) {
a.DeleteItemCore(e, g, false);
a.pendingItems = [];
a.cctx.executeQueryAsync(function () {
ULSrLq: ;
if (typeof a.rgehs != "undefined") {
if (a.rgehs.length == 1 && a.rgehs[0].get_serverErrorCode() == SP.ClientErrorCodes.redirect) {
GoToPage(a.rgehs[0].get_serverErrorValue());
return
}
removeNotification(f);
a.ShowErrorDialog(RefreshOnDialogClose)
} else RefreshPage(SP.UI.DialogResult.OK)
}, function () {
ULSrLq: ;
removeNotification(f);
typeof a.rgehs != "undefined" && a.ShowErrorDialog()
})
} else {
var d = b.HttpPath + "&Cmd=Delete&List=" + b.listName + "&ID=" + e + "&NextUsing=" + GetSource();
if (null != currentItemContentTypeId) d += "&ContentTypeId=" + currentItemContentTypeId;
SubmitFormPost(d)
}
}
}
With that you should be able to find what you need for your case.
If you use some jQuery/JavaScript in your page, you may also want to check SharepointPlus that provides some useful functions (like to get data from a list or to delete an item).
I figured it out!
I have a JS library called "SPAPI_Lists", which is from SharePoint Services, I believe.
It provides a function called quickDeleteListItem(listName, listItemId).
Code looks like this:
var urlThatContainsList = 'http://www.samplesite.com/sample';
var listName = 'Sample List';
var listItemId = 3;
new SPAPI_Lists(urlThatContainsList).quickDeleteListItem(listName, listItemId);
When fetching an item from a DOJO datastore, DOJO adds a great deal of extra fields to it. It also changes the way the data is structure.
I know I could manually rebuild ever item to its initial form (this would require me to make updates to both JS code everytime i change my REST object), but there certainly has to be a better way.
Perhaps a store.detach( item ) or something of the sort?
The dojo.data API is being phased out, partly because of the extra fields. You could consider using the new dojo.store API. The store api does not add the extra fields.
I have written a function that does what you are looking to do. It follows. One thing to note, my function converts child objects to the { _reference: 'id' } notation. You may want different behavior.
Util._detachItem = function(item) {
var fnIncludeProperty = function(key) {
return key !== '_0'
&& key !== '_RI'
&& key !== '_RRM'
&& key !== '_S'
&& key !== '__type'
};
var store = item._S;
var fnCreateItemReference = function(itm) {
if (store.isItem(itm)) {
return { _reference: itm.id[0] };
}
return itm;
};
var fnProcessItem = function(itm) {
var newItm = {};
for(var k in itm) {
if(fnIncludeProperty(k)) {
if (dojo.isArray(itm[k])) {
// TODO this could be a problem with arrays with a single item
if (itm[k].length == 1) {
newItm[k] = fnCreateItemReference(itm[k][0]);
} else {
var valArr = [];
dojo.forEach(itm[k], function(arrItm) {
valArr.push(fnCreateItemReference(arrItm));
});
newItm[k] = valArr;
}
} else {
newItm[k] = fnCreateItemReference(itm[k]);
}
}
}
return newItm;
};
return fnProcessItem(item);
};
NOTE: this function is modified from what I originally wrote and I did not test the above code.
Hallo,
i need to write some javascript that gets the contents of a userfield in a sharepoint-website. I can get most fields with the javascript-function 'getTagFromIdentifierAndTitle' of Using Javascript to Manipulate a List Form Field, but not UserFields.
So how can i get UserFields?
Thanks!
I traced how address book interacts with user field. To get values it uses function getUplevel(ctx) and to set values can be used function EntityEditorCallback(xml, ctx). First function will return html/xml mixed string with user information. Second function input must be special formatted xml string.
// Get values
var ctx='ctl00_m_g_e5a1501a_..._ctl04_ctl00_ctl00_UserField';
var values=getUplevel(ctx);
alert(values);
// Set values
var xml='<Entities Append="False" Error="" Separator=";" MaxHeight="3">'+
'<Entity Key="DOMAIN\\loginname" DisplayText="Display Name" IsResolved="True" Description="DOMAIN\\loginname">'+
'<ExtraData>'+
'<ArrayOfDictionaryEntry xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">'+
'<DictionaryEntry><Key xsi:type="xsd:string">DisplayName</Key><Value xsi:type="xsd:string">Display Name</Value></DictionaryEntry>'+
'<DictionaryEntry><Key xsi:type="xsd:string">Email</Key><Value xsi:type="xsd:string">Display.Name#domain.ee</Value></DictionaryEntry>'+
'<DictionaryEntry><Key xsi:type="xsd:string">SPUserID</Key><Value xsi:type="xsd:string">1</Value></DictionaryEntry>'+
'<DictionaryEntry><Key xsi:type="xsd:string">PrincipalType</Key><Value xsi:type="xsd:string">User</Value></DictionaryEntry>'+
'</ArrayOfDictionaryEntry>'+
'</ExtraData>'+
'<MultipleMatches />'+
'</Entity>'+
'</Entities>';
EntityEditorCallback(xml,ctx);
Tricky part is ctx attribute that must be target field id. In user field html there is no title attribute, so to find right element by display name with js is very complex. I suggest to pass field id to the javascript from server side. For example you can create custom WebPart where you write to the page field id-s from collection SPContext.Current.FormContext.FieldControlCollection.
Here is the custom code that I put together. It relies on the exact HTML that SharePoint uses for the PeoplePicker. It does work on both IE and Firefox. For the columnName parameter, pass the "public" name of the column, not the internal name.
function getParentElementByTagName(baseNode, tagName)
{
var currNode;
if(baseNode !== null)
{
currNode = baseNode.parentNode;
while((currNode !== null) && (currNode.nodeName != tagName))
{
currNode = currNode.parentNode;
}
return currNode;
}
else
{
return null;
}
}
function getPeoplePickerCell(columnName)
{
var search = 'FieldName="' + columnName + '"';
var nodes = document.getElementsByTagName("TEXTAREA");
for(var i=0; i < nodes.length; i++)
{
if(nodes[i].title == "People Picker")
{
var outerCell = getParentElementByTagName(nodes[i], "SPAN").parentNode.parentNode;
if(outerCell.innerHTML.indexOf(search) > 0)
{
return nodes[i].parentNode;
}
}
}
return null;
}
function getSPPeoplePicker(columnName, value)
{
var cell = getPeoplePickerCell(columnName);
if(cell !== null)
{
return cell.childNodes[0].innerHTML;
}
else
{
return null;
}
}
function setSPPeoplePicker(columnName, value)
{
var cell = getPeoplePickerCell(columnName);
if(cell !== null)
{
cell.childNodes[0].innerHTML = value;
cell.childNodes[1].value = value;
}
}
function disableSPPeoplePicker(columnName)
{
var cell = getPeoplePickerCell(columnName);
if(cell !== null)
{
disableElement(cell.childNodes[0]);
disableElement(cell.childNodes[1]);
}
}
function enableSPPeoplePicker(columnName)
{
var cell = getPeoplePickerCell(columnName);
if(cell !== null)
{
enableElement(cell.childNodes[0]);
enableElement(cell.childNodes[1]);
}
}
