onclick

一. 简介 jQuery是一个轻量级的、兼容多浏览器的JavaScript库。 jQuery使用户能够更方便地处理HTML Document、Events、实现动画效果、方便地进行Ajax交互，能够极大地简化JavaScript编程 　　jQuery产生的对象是jQuery独有的,只能自己调用,如果一个对象是jQuery对象,那么它就可以使用jQuery里的方法：例如$(“#i1”).html()。他的意思是：获取id值为 i1 的元素的html代码。其中 html () 是jQuery里的方法。相当于： document . getElementById ( "i1" ). innerHTML ; 　　我们在声明一个jQuery对象变量的时候在变量名前面加上$： var $variable = jQuery对像 var variable = DOM对象 $variable[0]//jQuery对象转成DOM对象 　　 　　获取jQuery: 　　jQuery不需要安装，把下载的jQuery库放到网站的一个公共位置，想要在某个页面上使用jQuery时，只需要在相关的HTML文档中引入该库文件即可。获得jQuery相关资源的网站地址如下： 　　官网： http://jquery.com/ 　　源码： https://github.com/jquery/jquery 　　文档：

I have a form which inserts data in DB on Submit button click but the problem is when client click the button multiple times its sends multiple create requests means multiple button click events for the same time of same data, which must not be. I tried to disable the button when client click the Submit button first time but after this it does not call server click event handler or not fire the server click event once it got disabled. How to handle this multiple click problem.. I used the following code to disable the button <script type="text/javascript"> function checkAuth(obj) { if(Page

I want to change the color of the grid cell using the number of grid position . e.g. I have 5X6 grid means 30 gridItems so i want to change the color of 21st position. Please tell me how can i do this Without clicking on the Grid View. You will need to define a custom adapter for this. In the getView() method of adapter you'll have to check the position parameter if is equal with 21. If it's equal with 21, then change the background for currently cell. If you did not had the experience to define a custom adapter yet, then it will make more sense to pass through an example first. Here's an

I have a href link and I would like it to be clicked when the page is loaded. $(document).ready(function() { $('#someLinkId').click(); }); Or $(document).ready(function() { $('#someLinkId').trigger("click"); }); $(document).ready(function () { $("#myLink").trigger('click'); }); as you can read in: http://docs.jquery.com/Events/trigger#eventdata $("#whateverid").trigger("click"); Where "whateverid" is the ID of the anchor tag, or whatever other selector you want to use. What's the point of loading the page if you're going to navigate away from it immediately? In addition to jQuery's triggering

Django之学员管理三 　　 web框架的本质： 　　　　本质是客户端和服务端的交互。用socket实现。 　　　　socket客户端（浏览器） 　　　　　　2、发送ip和端口，http://www.baidu.com：80/index/ (http://www.baidu.com：80) 为ip和端口，（/index/ ）是url。客户端往服务端发送请求时，是要分post和get两种请求方式。 　　　　　　4、接受响应，普通的响应就是正常的拿到响应体浏览器是处理呈现，而重定向是要再发一次http请求，进行一次跳转才可以。 　　　　socket服务端（服务器） 　　　　　　1、服务端socket先运行起来进行监听 while循环来持续监听ip和端口，等待客户连接。 　　　　　　3、接受请求，处理并返回相应的结果，返回的本质是一堆字符串。返回的有响应头和响应体。还有一种响应方式，是重定向返回，在重定向返回里是没有响应体的，只有响应头。在响应头里有一区别是多了一个location，在location里定义要响应跳转的url。 　　 django的web框架： 　　　　a、创建project：django-admin startproject mysite 　　　　b、配置：模板，静态文件，csrf 　　　　c、路由关系：url-》函数 　　　　d、视图函数： 　　　　　　　　def

Am a bit new to javascript. This question might sound a bit too silly, but I'm not able to figure it out why the following doesn't work in IE and works in firefox.. <select multiple="multiple"> <option value="tx" onClick="alert('tx');">Texas</option> <option value="ak" onClick="alert('ak');">Alaska</option> <option value="ca" onClick="alert('ca');">California</option> <option value="ws" onClick="alert('ws');">Washington</option> <option value="tn" onClick="alert('tn');">Tennessee</option> </select> The alert doesn't come up in IE (I'm using IE8). But it works in firefox!!!!! According to

<a href="<?=$rowz[0]?>" onClick="countLinks('<?=$row[6]?>','<?=$indexl?>')">[Link <?=$j++?>]</a> The problem is that it doesn't work with middle button on IE or firefox. In fact, the countLinks using middle button is called only with chrome. I think I need a Jquery function like mouseup event, just I don't know how call that function, which it calls countLinks with those parameters parameters. Any help? jAndy You're right. You need a mousedown or mouseup event to determine which mouse button was actually clicked. But first of all, you need to get rid of that inline-event handler onclick and

　　今天闲来无聊，想写点什么，突然想到用javascript写一个计算器。程序还存在很多的Bug，先在这里记录一下，以后慢慢更正。 代码如下： <!

Update: This only applies to jQuery 1.8 and below. This was fixed in jQuery 1.9 . Here is my minimal jsfiddle example: http://jsfiddle.net/8fuEJ/ . I'm using Google Chrome, if that makes a difference. I have a checkbox: <input type="checkbox" id="wtf"> And I have a jquery event handler: $('#wtf').click(function(ev) { alert(this.checked); }); So far, so good. When I click the checkbox, I first see the checkmark appear, then the alert "true" (in that order). When I click it again, I see the checkmark disappear, then the alert "false". The problem comes when I programmatically trigger the click
