I've searched the jQuery SPServices code examples and MSDN references for an simple example how to update several ListItems using a Where-Clause.
Code for updating a single ListItem with ID = 500, looks like this:
$(divId).html(waitMessage).SPServices({
operation: "UpdateListItems",
listName: "MyList",
ID: 500,
valuepairs: [["MyField", 1]],
completefunc: function (xData, Status) {
$(divId).html("");
}
});
But is it also possible to add a Where like :
<Where><Eq><FieldRef Name="Status"/><Value Type="Text">Ready</Value></Eq></Where>
Or should I do it like this post ? (First retrieve the list and then do a loop for each item ?)
