<input type=”button” id=”btnDeleteItems” value=”Click Here”/>
<script src=”https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js”></script>
<script>
$(document).ready(function(){
$(“#btnDeleteItems”).click(function(){
DeleteAllItems();
});
});
function DeleteAllItems(){
var ctx = SP.ClientContext.get_current(),
list = ctx.get_web().get_lists().getByTitle(‘Ideas’),
query = new SP.CamlQuery(),
items = list.getItems(query);
ctx.load(items, “Include(Id)”);
ctx.executeQueryAsync(function () {
var enumerator = items.getEnumerator(),
itemArray = [];
while (enumerator.moveNext()) {
itemArray.push(enumerator.get_current());
}
for (var s in itemArray) {
itemArray[s].deleteObject();
}
ctx.executeQueryAsync();
});
}
</script>
Hope this will be helpful.
