阅读更多关于 Handling itemclick event on tree panel Extjs 4

what I am trying to do is to get different reaction on a different tree LEAF click! var myTree = Ext.create('Ext.tree.Panel', store: store, rootVisible: false, border: false, listeners: { itemclick: function(index) { var record = store.getAt(index); alert(record); } } }); I tried with index, to get the index of leaf, nothing.

Maybe a simple example of itemclick: function(Ext.view.View this, Ext.data.Model record, HTMLElement item, Number index, Ext.EventObject

问题 Normally it's enough to set focusable , focusableInTouch + clickable to false. But here it does not work.

RatingBar onClick

阅读更多关于 RatingBar onClick

I have a ListView that uses different XML files to create Views and make items out of. One of these XML files contains a RatingBar. Everything displays and looks excellent. I'm trying to attach an onClick handler to the RatingBar to launch a new Activity. My RatingBar is of style ?android:attr/ratingBarStyleSmall; so it's just an indicator (I want the small RatingBar click to take the user to an Activity where they can do various ratings). My problem is the onClick handler for the RatingBar never gets executed. What makes it more interesting is that I've used the same code to make a

Web系统页面打印技术实现与分析

阅读更多关于 Web系统页面打印技术实现与分析

1 Web页面打印概述应用WEB化，不论对开发商，还是对用户来说，实在是一种很经济的选择，因为基于WEB的应用，客户端的规则很简单，容易学习，容易维护，容易发布。在WEB系统中，打印的确是个烦人的问题。要么自己开发打印控件，如果项目时间紧，肯定来不及。这对程序员来说，因为浏览器的局限性，却要面对很多挑战。怎么样来进行基于WEB的套打，就是这么一个令多数程序员头痛不已的问题。基于WEB的套打，难度在于要将浏览器中呈现的HTML，精确地打印到票据中，而且能够实现对分页位置的控制。本文将介绍常用的Web打印与套打方案，同时提供一些免费的打印控件，供大家学习参考。 2 常用Web页面打印方案 2.1 浏览器的打印功能这种方案的优势是不需要对浏览器作任何扩充，是最简单的办法，但问题也最多，如： 1. 不能精确分页。浏览器一般是根据用户设置的页面大小，web页面的内容多少，来自行决定分页位置，程序员很难控制。会有页脚页眉干扰。 2. 不能准确对齐边边距及打印文字。 3. 不能解决连续打印。比如，不是仅打印一张票据，而是连续一次打印若干个票据。 2.2 使用PDF文件用这种方式，就是从服务器端下载一个pdf文件流，在IE中用adobe插件打开，然后用adobe的打印菜单进行打印，虽然这种方案，也能实现精确套打，但需要下载adobe插件。这是国外报表工具经常推荐的一种打印方法

How should I fire Javascript blur event after click event that causes the blur?

阅读更多关于 How should I fire Javascript blur event after click event that causes the blur?

I have run into this problem a few times and I'm not happy with the solutions I've used before. I have an input box with a blur event that validates the content of it and a button which will fill the input box on click. The problem is clicking the button fires the input blur event and then the button click event so content inserted by the button is not what is validated. See http://jsfiddle.net/jakecr/dL3K3/ I know this is the correct behavior but I can't think of a clean way to get around the problem. We had a similar problem at work. what we figured out in the end was that the mousedown
