Question

我对knockoutjs很新。我尝试从[knockout js sample]（http://knockoutjs.com/documentation/options-binding.html）稍微修改一下，但它不起作用。

<select data-bind="option: availCustomers, optionsText: 'CustomerName', 
value: selectedCustomer, optionsCaption: '--- Choose ---'">
</select>

和viewmodel：

<script>
function customerViewModel() {
    var self = this;
    self.availCustomers = ko.observableArray();
    self.selectedCustomer = ko.observable();
};

var Customer = function (id, name) {
    this.CustomerId = id;
    this.CustomerName = name;
};

$(document).ready( function() {
    var cvm = new customerViewModel();
    cvm.availCustomers = new ko.observableArray([
        new Customer("12345", "ABC"),
        new Customer("54321", "XYZ")
    ]);
    ko.applyBindings(cvm);
});
</script>

所以请指导我

Answer 1

我认为这只是一个错误的错误，bind的参数叫做“options”。

<select data-bind="options: availCustomers, optionsText: 'CustomerName', 
value: selectedCustomer, optionsCaption: '--- Choose ---'">
</select>

knockoutjs选择选项不绑定
