ECMAScript对列表项的增删改查

一、新增

代码

<script type="text/javascript">

var siteUrl ='/sites/MySiteCollection';

function createListItem() {

var clientContext =new SP.ClientContext(siteUrl);
var oList = clientContext.get_web().get_lists().getByTitle('Announcements');

var itemCreateInfo =new SP.ListItemCreationInformation();
this.oListItem = oList.addItem(itemCreateInfo);

oListItem.set_item('Title', 'My New Item!');
oListItem.set_item('Body', 'Hello World!');

oListItem.update();

clientContext.load(oListItem);

clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
}

function onQuerySucceeded() {

alert('Item created: '+ oListItem.get_id());
}

function onQueryFailed(sender, args) {

alert('Request failed. '+ args.get_message() +'\n'+ args.get_stackTrace());
}

</script>

 

二、查询 

代码

var product;
function getProductById(productId) {
try {
var context =new SP.ClientContext.get_current();
var web = context.get_web();
var list = web.get_lists().getByTitle('product');
this.product = list.getItemById(productId);
context.load(product, 'ProductName', 'ProductDescription', 'ProductType', 'LaunchDate', 'AvailableQuantity');
context.executeQueryAsync(Function.createDelegate(this, this.productReceived), Function.createDelegate(this, this.failed));
}
catch (e) {
alert(e);
}
}

 

代码

var productcollection;
function getProducts(title) {
try {
var context =new SP.ClientContext.get_current();
var web = context.get_web();
var list = web.get_lists().getByTitle('product');
var query ='<View Scope=\'RecursiveAll\'>'+
'<Query>'+
'<Where>'+
'<Contains>'+
'<FieldRef Name=\'ProductName\'/>'+
'<Value Type=\'Text\'>'+ title +'</Value>'+
'</Contains>'+
'</Where>'+
'</Query>'+
'</View>';
var camlQuery =new SP.CamlQuery();
camlQuery.set_viewXml(query);

this.productcollection = list.getItems(camlQuery);
context.load(this.productcollection, 'Include(ProductName, ProductDescription, ProductType, LaunchDate, AvailableQuantity)');
context.executeQueryAsync(Function.createDelegate(this, this.productsReceived), Function.createDelegate(this, this.failed));
}
catch (e) {
alert(e);
}
}
function productsReceived() {
alert('got products');
prcessProducts(this.productcollection);
}
function failed(sender, args) {
alert('failed. Message:'+ args.get_message());
}

 

   function onQuerySucceeded(sender, args) {
    var listItemInfo = '';
    var listItemEnumerator = collListItem.getEnumerator();        
    while (listItemEnumerator.moveNext()) {
        var oListItem = listItemEnumerator.get_current();
        listItemInfo += '\nID: ' + oListItem.get_id() + 
            '\nDisplay name: ' + oListItem.get_displayName();
    }
    alert(listItemInfo.toString());
  }

  function onQueryFailed(sender, args) {
    alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
  }
