Question

我在模型中有难度访问器：

public int Difficulty
{
    get;
    set;
}

我的HTML看起来像这样：

<a href="#" onclick="easy()">Easy</a>
<a href="#" onclick="average()">Average</a>
<a href="#" onclick="hard()">Hard</a>

然后我想通过按任意链接来改变难度值。我试着用下面的脚本来做，但它显然不起作用。我该怎么办？

function easy() {
    @Model.Difficulty = 15
    location.reload();
}
function average() {
    @Model.Difficulty = 30
    location.reload();
}
function hard() {
    @Model.Difficulty = 45
    location.reload();
}

您可以发出ajax请求

function easy()
{
    var difficulty = 15;
    changeDifficulty();
}

function changeDifficulty()
{
    var serviceURL = '/Controller/changeDifficulty';
    $.ajax({
        url: serviceURL,
        data: { d: difficulty },
        type: 'POST',
        success: function () {
            alert("Success");
        },
        error: function () {
            alert("Something went wrong");
        }
    });
}

在您的控制器中

public void changeDifficulty(int d)
{
    //Update your model here
}
