Android make view disappear by clicking outside of it

阅读更多关于 Android make view disappear by clicking outside of it

I have some views that I make visible upon a button press. I want them to disappear if I click outside of those views. How would this be done on Android? Also, I realize that the "back button" can also assist Android users with this - I might use that as a secondary way to close the views - but some of the tablets aren't even using a 'physical' back button anymore, it has been very de-emphasized. An easy/stupid way: Create a dummy empty view (let's say ImageView with no source), make it fill parent If it is clicked, then do what you want to do. You need to have the root tag in your XML file to

GridView高效分页+搜索的完整实现

阅读更多关于 GridView高效分页+搜索的完整实现

前言：公司项目开发，上周的任务是做基础数据的管理。在Sharepoint2010里边内嵌asp.net的aspx页，遇到了各种各样奇葩的问题，因为之前对sharepoint只是有一些了解，但是没有设计到具体的编程工作，这一次算是初次接触吧。其中有一部分基础数据数据量很大，大致有十多万，因为是对基础数据的维护，所以还需要对数据进行列表展示，增删改查什么的，大家都知道Asp.net里边的GridView有自带的分页，但是，那个分页对于少量的数据还好，对于这种数十万的数据量而言，这种分页方式简直就是灾难。网上关于GridView高效分页的东西有很多，找了一个自己改了改。用着效果还不错，和大家分享一下。这是分页的效果图下边就讲一下具体的实现，首先声明，这个东西是不是我原创的，只是在此基础上进行了修饰和完善。希望能给各位有所启发。一、前台布局 <div> <div id="main"> <div id="search"> <table> <tr> <td> <asp:Label ID="lb" runat="server" Text="姓名"></asp:Label></td> <td> <asp:TextBox ID="SearchName" runat="server"></asp:TextBox> </td> <td> <asp:Button ID="btnSearch"

Is it possible to get the value of a <td> element using onclick?

阅读更多关于 Is it possible to get the value of a element using onclick?

I currently have a table that has a list of email template names being echoed using php. Below is part of the php code. I'm trying to grab the table value and pass it to my JS file where a future AJAX command will pass it to a different file (that I won't have any issues with). My first attempt to alert out the value stated that the value was undefined. My second attempt showed the type of element it was inside (at the time it was a span). Now it's not showing anything. Suggestions? PHP code: <table class="departments"> <tr> <th scope="col" style="width: 175px;">Email Name</th> '; $get_depts =

Whats the difference between onclick and onsubmit?

阅读更多关于 Whats the difference between onclick and onsubmit?

问题 It's not like I haven't googled it... But still I couldn't understand when onsubmit is used and when onclick is used? 回答1: They're two completely separate events. onclick events fire when the user uses the mouse to click on something. onsubmit events fire when a form is submitted. The origin of this event can sometimes be traced back to an onclick (like clicking the "submit" button) but it can also come from a keyboard event (like pressing enter ). This implies that using onclick on a submit
