ajax 动态加载的内容，相应的js也要在回调里加载

$(".getStudent").click(function(event){
        console.log($(this));
        var account = $(this).attr("target")

        $.ajax({
            url: ‘/getStudent‘,
            type: ‘POST‘,
            dataType: ‘html‘,
            data: {studentAccount:account},
        })
        .done(function(data) {
            console.log(data);
            $("#replacable").replaceWith(data);
            $(".getHomeworkState").click(function(event){
                    console.log($(this));

                    var id = $(this).attr("target");
                    var title = $(this).text();
                    var student = {{.Account}}
                    $.ajax({
                        url: ‘/getHomeworkState‘,
                        type: ‘POST‘,
                        data: {
                            homeworkId:id,
                            title:title,
                            account:student
                        },
                    })
                    .done(function(data) {
                        console.log(data);
                        console.log("success");
                    })
                    .fail(function() {
                        console.log("error");
                    })
                    .always(function() {
                        console.log("complete");
                    });    
            });
            console.log("success");
        })
        .fail(function() {
            console.log("error");
        })
        .always(function() {
            console.log("complete");
        });
        
});
