Question

我一直收到错误：未捕获的TypeError：无法读取未定义的属性'fromJS' 想法是有2页，其中是ui表示，另一个是het viewmodel。我有2页：

的index.html

<link rel="stylesheet" href="bin/styles/kendo.common.min.css" />
<link rel="stylesheet" href="bin/styles/kendo.default.min.css" />
<link rel="stylesheet" href="bin/styles/kendo.dataviz.min.css" />
<link rel="stylesheet" href="bin/styles/kendo.dataviz.default.min.css" />

<script src="bin/js/jquery.min.js"></script>
<script src="bin/js/kendo.all.min.js"></script>
<script src="bin/knockout-3.2.0.js"></script>
<script src="bin/knockout.mapping-latest.js" type="text/html"></script>

<script src="IndexViewModel.js"></script>

<script>
    $(function() {
        var indexVM = new IndexViewModel.ViewModel();
        ko.applyBindings(indexVM);
    });
</script>


<table>
    <thead><tr>
        <th>First Name</th>
    </tr></thead>
    <tbody data-bind="foreach: Users">
        <tr>
            <td data-bind="text: UserName"/></td>
        </tr>
    </tbody>
</table>

和IndexViewModel.js：

var IndexViewModel = (function (IndexViewModel) {
IndexViewModel.ViewModel = function() {
    var self = this;
    self.Users = ko.observableArray();
    $.ajax({
        url : 'GetUsers.php',
        dataType: 'json',
        success: function(data){ //json string of the student records returned from the server
        self.Users = ko.mapping.fromJS(result.data, {}, self.Users);
        }
    });
}
    return IndexViewModel;
}(IndexViewModel || {}));

我做错了什么/失踪了？

由于

Answer 1

解决了这个问题。问题是

<script src="bin/knockout.mapping-latest.js" type="text/html"></script>

更改为：

<script src="bin/knockout.mapping-latest.js"></script>

起飞： type =“text / html”

无法在外部viewmodel.js中读取未定义的属性'fromJS'
