<input class="jProblemClass" id="CheckBox{%= ID %}" type="checkBox" onchange="problemPicker.onChangeProblemCheckBox('{%=ID %}');"/>

首先检查或取消选中后没有任何反应. Afetr第二次点击,调用我的函数problemPicker.onChangeProblemCheckBox,但我先得到ID检查.为什么？可以帮助我吗？

onChangeProblemCheckBox: function(id) {
    if ($('#CheckBox' + id).attr("checked") == true) {
        problemPicker.addtocheckProblems(id);

        var checkBoxes = $('.jProblemClass:checked');

        if ((checkBoxes.length > general.limit) && (general.limit != 0)) {
            alert('The limit of ' + general.limit + ' problems exceeded. Please deselect ' + (checkBoxes.length - general.limit).toString() + '.');
        }
    } else {
        problemPicker.delFromCheckProblems(id);
    }
},
