如何将TRUE从JavaScript传递到C＃脚本

Question

I have:

function SelectSubTopics() {
    $.ajax({
        url: "/Administration/Tests/SelectSubTopics",
        data: { DataSource: $('#DataSource').val(),
            testID: $('#TestID').val(),
            showAll: True
        },
        success: function (data) {
            $('#TID').html(data);
        }
    });
}

I would like to pass a value of True through to the C# program which accepts a bool for the showALL parameter but I am getting a javascript error saying "SCRIPT5009: 'True' is undefined " Is there some special way to pass true?

Answer 1

Lower case: true - that's all. If the case is important, use a string: "True"

Answer 2

Javascript is case-sensitive which means true is not True . Also note that showAll in your server-side script is not bool it's a string .
