Добавление/Удаление/Обновление/Получение элементов списка используя ECMAScript

1. Добавление

function addProduct(productName, productDesc, productLaunchDate, productAvailQty, productType) {
    try {
        var context = new SP.ClientContext.get_current();       
        var web = context.get_web();
        var list = web.get_lists().getByTitle('product');

        var listItemCreationInfo = new SP.ListItemCreationInformation();
        var newItem = list.addItem(listItemCreationInfo);
        newItem.set_item('Title', productName);
        newItem.set_item('ProductName', productName);
        newItem.set_item('ProductDescription', productDesc);
        newItem.set_item('LaunchDate', productLaunchDate);
        newItem.set_item('AvailableQuantity', productAvailQty);
        newItem.set_item('ProductType', productType);

        newItem.update();
        context.executeQueryAsync(Function.createDelegate(this, this.success), Function.createDelegate(this, this.failed));
    }
    catch (e) {
        alert('error:' + e.Message);
    }
}
function success() {
    alert('success');
}
function failed(sender, args) {
    alert('failed. Message:' + args.get_message());
}

2. Удаление

function deleteProduct(productId) {
    var context = new SP.ClientContext.get_current();
    var web = context.get_web();
    var list = web.get_lists().getByTitle('product');
    var itemToDelete = list.getItemById(productId);
    itemToDelete.deleteObject();
    context.executeQueryAsync(Function.createDelegate(this, this.success), Function.createDelegate(this, this.failed));
}
function success() {
alert('success');
}
function failed(sender, args) {
alert('failed. Message:' + args.get_message());
}

3. Получение записи по ID

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);
    }
}
function productReceived() {
    alert('got product');
    gotProduct(this.product);
}
function failed(sender, args) {
    alert('failed. Message:' + args.get_message());
}

4. Поиск записи в листе

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());
}

5. Обновление

function updateProduct(productid, productName, productDesc, productLaunchDate, productAvailQty, productType) {
    var context = new SP.ClientContext.get_current();
    var web = context.get_web();
    var list = web.get_lists().getByTitle('product');
    var product = list.getItemById(productid);
    product.set_item('ProductName', productName);
    product.set_item('ProductDescription', productDesc);
    product.set_item('ProductType', productType);
    product.set_item('LaunchDate', productLaunchDate);
    product.set_item('AvailableQuantity', productAvailQty);
    product.update();
    context.executeQueryAsync(Function.createDelegate(this, this.success), Function.createDelegate(this, this.failed));
}
function success() {
alert('success');
}
function failed(sender, args) {
alert('failed. Message:' + args.get_message());
}
