我正在尝试创建一个对象并从中分配单击处理程序.我已经意识到我不能这样做,因为“this”与按钮相关联,而不是对象文字,打破了对函数的访问.

“未捕获的TypeError：对象#没有方法’clearSelection’”

请看下面的小提琴.

这是代码供参考.除了说明问题外,它不应该在这个阶段做任何有用的事情:)

function ThingConstructor(someData) {
    var button = $("#someButton");
    return {

        initialise: function () {
            button.click(function () {
                // I want "this.clearSelection();" to target the 
                // "clearSelection" function below.
                // Instead,it targets the button itself.
                // How can i refer to it?
                this.clearSelection();
            });
        },clearSelection: function () {
            this.populateList($("#stuff"),someData);
            $("#adiv").empty();
            console.log("clearSelection");
        },populateList: function (var1,var2) {
            //do something to a list
        }
    }
}

$(function () {
    var test = ThingConstructor("someData");
    test.initialise();
});
