调用ViewModel范围之外的函数

Question

I have the following code outside the scope of my view model and i am attempting to call it with a click binding.

function Policy(data) {
    var self = this;
    Object.keys(data).forEach(function(prop) {
        self[prop] = data[prop];
    });

    var generate = function() {
        console.log("test");
        // window.open("www.google.com")
        // window.open("{{ url_for('genreport') }}/" + qvm.letter() + '/' + self.id);
    }

}

however, when i try to call the function i get that generate is not defined. the code for my binding is below

<button class="btn btn-lg btn-primary btn-block" data-bind="click: function(){ generate() }">Generate</button>

I have tried calling Policy.generate, $data.generate, and i cannot get this function to call.

I know this issue is simple and im probably missing something that should be smashing me in the face but i'm oblivious, any help would be appreciated.

修复只是将上述功能放在我的ViewModel范围内，现在已修复。

You have declared generate using a local variable. It is not visible outside the scope of Policy . If you want to create Policy.generate , you should do that:

Policy.generate = function () {
