无法读取外部 viewmodel.js 中未定义的 属性 'fromJS'

cannot read property 'fromJS' of undefined in external viewmodel.js

我不断收到错误消息:未捕获类型错误:无法读取未定义的 属性 'fromJS' 这个想法是有 2 个页面,其中 ui 表示,另一个是 het viewmodel。 我有 2 页:

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/遗漏了什么?

谢谢

问题已解决。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"
