Javascript 仅检测到一些表单元素事件

谢谢你的帮助。我在web应用程序中有一系列用于UI的表单元素。我使用jQuery创建元素并添加侦听器。事件发生时，不会监听#topbar DIV中的控件，但会监听#sidebar DIV中的控件。我不知道为什么。你能帮忙吗，谢谢。下面是创建控件的函数

function constructToolbars(){
        //----------------------------TOPBAR-------------

        $('#topbar').html('ZONE: ');

        var zoneRadios = ["All", "None"];

            $('<input />', {
                type: 'radio',
                id: 'zone' + zoneRadio, name: "zoneRadios", value: zoneRadio,

zoneRadio变种；
对于（var i=0；i来说，这些行实际上重置了HTML，从而操纵了DOM

topbar.innerHTML+=”----时间：“

topbar.innerHTML+=”：“

这实际上相当于将HTML重置为

topbar.innerHTML=topbar.innerHTML+”----时间：“

请集体绑定结尾处的所有事件以避免这种情况，或使用更高的侦听器，如
$（“#topbar”）。在（“更改”、“区域”、“读取工具栏”）上

请不要在（“更改”，ReadToolbar）

上为您解密这段代码，请只发布相关部分和测试用例。这样做可能会帮助您自己解决问题……您能指出代码中哪些事件没有被触发吗？（仅通过相关事件侦听器旁边的注释）大卫，我已经按照你的建议做了好几个小时了。现在，我不知道问题是什么，所以我发布了所有可能涉及的内容。我的问题的文字是为了帮助任何人关注我认为的问题是什么，但再一次，我不确定问题是什么。非常感谢，就是这样。这不是直觉告诉我为什么innerHTML+=会导致这种情况-谢谢你指出。你能为这些元素的水平布局推荐一种更好的方法吗？
