javascript - 将事件处理程序附加到正文时，e.stopImmediatePropagation() 未按预期工作

Question

如果满足特定场景，我想限制对 anchor 按钮单击的进一步操作。在将事件处理程序附加到正文时，我下面给出的一段代码不起作用。 anchor 是

<a class="btn btn-primary waves-effect waves-light" id="btn-ContinueToBeneficiary" role="button">Continue</a>

jquery部分是

$('body').on('click', '#btn-ContinueToBeneficiary', function (e) {
        debugger;

        if ($(':radio[name=payeragency]:checked').length <= 0) {
            debugger;
            $('#errorPayerAgency').show();
            e.preventDefault();
            e.stopPropagation();
        }
        else {
            $('#errorPayerAgency').hide();
        }
        debugger;
        otm.ApplyOption({            
            itemList: {
                "items": [
                    {
                        //Tab bar
                        elem: "screen_3",
                        mode: "add",
                        type: "id",
                        classToAdd: "active"
                    },
                    {
                        // Tab bar
                        elem: "screen_2",
                        mode: "remove",
                        type: "id",
                        classToRemove: "active"
                    },
                    {   // Inner content div
                        elem: "beneficiary",
                        mode: "add",
                        type: "id",
                        classToAdd: "active"
                    },
                    {
                        // Inner content div
                        elem: "enter_amount",
                        mode: "remove",
                        type: "id",
                        classToRemove: "active"
                    }
                ]
            }
        });
    debugger;
        $("#screen_3 a").click();
    })

;

理想情况下，当选中的单选按钮数量小于或等于零时，jquery 应该停止进一步执行

if ($(':radio[name=payeragency]:checked').length <= 0) {
            debugger;
            $('#errorPayerAgency').show();
            e.preventDefault();
            e.stopPropagation();
        }

但它会继续执行下去。任何人都可以帮助我。

请使用以下代码更新您的 if 条件。

if ($(':radio[name=payeragency]:checked').length <= 0) {
            debugger;
            $('#errorPayerAgency').show();
            return false;
        }
