Sharepoint - Get a list Id using javascript?
Should be some thing like following
var context = new SP.ClientContext.get_current();
var web = context.get_web();
var list = web.get_lists().getByTitle('Name of the List');
context.load(list, 'Id');
In the success, try
var listId = list.get_id();
Update for web
is undefined
Run code under ExecuteOrDelayUntilScriptLoaded()
ExecuteOrDelayUntilScriptLoaded(getListId, "sp.js");
var list;
function getListId() {
var context = new SP.ClientContext.get_current();
var web = context.get_web();
list = web.get_lists().getByTitle('Name of the List');
context.load(list, 'Id');
context.executeQueryAsync(Function.createDelegate(this, success), Function.createDelegate(this, error));
}
function success() {
listId = list.get_id();
console.log(listId);
}
function error(sender, args) {
alert('Request failed. ' + args.get_message() +
'\n' + args.get_stackTrace());
}
