问题 I'm struggling with the following problem: I dynamically create input elements and I try to attach a datepicker to it. But it works only when I click somewhere outside the input element and then on the input again. Console log is working fine on first click, so I don't know what is the issue here? $(document).ready(function(){ $("div.single_condition").on("click", "input", function(){ if($("select.select_operator").val() == '>'){ console.log("O.K."); $(this).datepicker(); } else { console.log

安卓开发电商mvp框架和流式布局，搜索框

阅读更多关于安卓开发电商mvp框架和流式布局，搜索框

在我看来mvp框架其实是mvc框架变种产品。讲原本的activity/fragment的层次划分成present层和view层。m还是原来的实体层用来组装数据，p层则用来隔离view层，被称为中介层，v层还是view层主要用来展示数据的层。如下图所示：有了present层之后呢？view层就专心在activity/fragment里面主要去处理视图层和维护自己的生命周期，将业务逻辑委托给present层，present层作为实体层和视图层的中介。实体层和视图层不直接进行交互，而是通过委托给persent层进行交互，这样做的好处是：分离了视图逻辑和业务逻辑，降低了耦合 Activity只处理生命周期的任务，代码变得更加简洁视图逻辑和业务逻辑分别抽象到了View和Presenter的接口中去，提高代码的可阅读性 Presenter被抽象成接口，可以有多种具体的实现，所以方便进行单元测试把业务逻辑抽到Presenter中去，避免后台线程引用着Activity导致Activity的资源无法被系统回收从而引起内存泄露和OOM 方便代码的维护和单元测试。以下主要展示的功能和框架有： MVP架构+基类+Volley封装底部标签与Fragment的联动 arguments动态传值接口回调 js交互，有参无参调用，弹框自定义全局异常捕获 base封装Activity和Fragment

问题 Folks I'm a complete novice so apologise upfront for what is going to be a very basic question, I'm sure. I have a javascript file that is linked to a html file which contains a number of buttons. The onclick event for one such button seems to be completely bypassing the onlick event and triggering as soon as the page opens. Any ideas? Sorry to ask what is likely something really basic, but I have lost count of the hours I have spent trying to get it to work only on the "click" event.... in
