I have a list in SharePoint 2010 with some columns. All are default types. So I have
"Single line of text"
"Multiple line of text"
"Date and Time"
"Choice"
"Number"
"Currency"
"Person or Group"
My aim is to have a custom ribbon tab or group where I can perform some action on this list. As a starting point I created an Empty Element in my Visual Studio solution and put inside Elements.xml my buttons. This works so far. I also figured out how to do a postback to react on pressed button. This postback refers to a JavaScript file.
Before performing some action I tried first to read the given contents and return them using alert('first field: ' + field1)
. In first called function I have
function calledPostbackFunction(string button) {
var context = SP.ClientContext.get_current();
this.site = context.get_site();
this.web = context.get_web();
context.load(this.site);
context.load(this.web);
context.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceded(button), Function.createDelegate(this, this.onQueryFailed));
How can I get the content from listed column types? I remember that I was able to read single text line and choice, but the rest crashed. So I guess I have to convert it any way. But how? IntelliSense doesn't helps a lot.
SUBQUESTION: I would skip using EcmaScript if you can tell me how to doPostBack to a .cs file where I can use Client Object Model. I found something but didn't work/ understand.
Yes, I though this will be easy, but it was not. At least because I only know C# a bit, no EcmaScript.
Thanks.
Okay, I got a solution Sharepoint.Stackoverflow.com from user Vardhaman Deshpande. This works.
Here is How to get the value of each type of field:
Title – SP.ListItem.get_item(‘Title‘);
ID – SP.ListItem.get_id();
Url -SP.ListItem.get_item(‘urlfieldname‘).get_url()
Description – SP.ListItem.get_item(‘descriptionfieldname‘).get_description();
Current Version – SP.ListItem.get_item(“_UIVersionString“);
Lookup field – SP.ListItem.get_item(‘LookupFieldName’).get_lookupValue();
Choice Field – SP.ListItem.get_item(‘ChoiceFieldName‘);
Created Date – SP.ListItem.get_item(“Created“);
Modified Date – SP.ListItem.get_item(“Modified“); -> case sensitive does not work with ‘modified’
Created By – SP.ListItem.get_item(“Author“).get_lookupValue());
Modified by – SP.ListItem.get_item(“Editor“).get_lookupValue());
File – SP.ListItem.get_file();
File Versions - File.get_versions();.
Content Type – SP.ListItem.get_contentType();
Parent List – SP.ListItem.get_parentList();
UPDATE: The following code is working and tested.
var item;
function getItemById(itemId){
var clientContext = new SP.ClientContext.get_current();
var web = clientContext.get_web();
var list = web.get_lists().getByTitle('myList');
item = list.getItemById(itemId);
clientContext.load(item);
clientContext.executeQueryAsync(onSuccess, onFailure);
}
function onSuccess(){
alert(item.get_item("My User column").get_lookupValue());
}
function onFailure(){
alert('Failure!');
}
