阅读更多关于表单的onsubmit和onclick事件

1.执行顺序：点击按钮(type为submit的按钮)---> onclick ----> onsubmit ----> 表单提交，刷新页面 2.阻止事件（分两种）： a. 采用这种绑定时： <form onsubmit="bc()" action="123"> <button type="submit" onclick="btnClick()">提交</button> onclick和onsubmit事件中window.event.preventDefault() ; 而return false无效 onclick和onsubmit事件中window.event.preventDefault() ; 而return false无效 b. 采用这种绑定时： <form onsubmit="return abc()" action="123"> <button type="submit" onclick="btnClick()">提交</button> onclick和onsubmit事件中window.event.preventDefault()和return false都有效 3.注意：绑定onsubmit事件时，事件的名称不能为 submit，不然不执行。来源： oschina 链接： https://my.oschina.net/u/3272730/blog/1631275

a标签的onclick和href同时存在的写法

阅读更多关于 a标签的onclick和href同时存在的写法

经常用到a标签，但是对于标准的写法很多时候会忽略掉，今天就简单的普及一下标准写法 <a href="javascript:void(0)" onclick="subgo()">点我</a> 这个就是标准写法，点击a标签，调用的是subgo() <a href="#" onclick="subgo()">点我</a> <a href="javascript:void(0)" onclick="subgo()">点我</a> 以上两者的区别在于： 1、#代表的是网页的上端； 2、javascript:void(0) 仅仅表示一个死链接，没有任何信息；所以为了用户点击时页面不来回跳动，就最好使用javascript:void(0)。大家都知道，链接的 onclick 事件被先执行，其次是 href 属性下的动作（页面跳转，或 javascript 伪链接）所以建议大家尽量使用标准的 <a href="javascript:void(0)" onclick="doSomething();return false;">test</a> 来源： oschina 链接： https://my.oschina.net/u/3315736/blog/1563133

<a href="#" onclick="" 注意事项

阅读更多关于

使用javascript的时候,通常我们会通过类似: < a href="#" onclick="javascript:方法">提交< /a> 的方式,通过一个伪链接来调用javascript方法.这种方法有一个问题是: 虽然点击该链接的时候不会跳转页面.但是滚动条会往上滚,解决的办法是返回一个false. 如下所示: < a href="#" onclick="方法;return false;">提交< /a> 或< a href="javascript:void(0)" onclick="方法">提交< /a> 同时页面链接地址也不会被添加上# 来源： oschina 链接： https://my.oschina.net/u/265431/blog/66697

Click handler on <svg> element

阅读更多关于 Click handler on element

It seems that using a <svg:svg> </svg:svg> element does not render anything in Safari or Chrome, but using <svg> </svg> works fine. However, adding an onclick only works on <svg:svg> elements. What is the proper way to do this? This jsfiddle demonstrates the problem (compare Safari/Chrome to Firefox). Malharhak Okay, turns out that the first way of creating a SVG creates the onclick only on the drawn part. That means you can actually do something nice (maybe not useful in your case). In this fiddle , I created two separate onclick s, one that triggers when you click specifically the drawing

I am new to DART. I read the language overview and checked example code in DART editor. So far i could not find how to handle events in DART. For e.g. onclick="call_dart_method()". How can we handle events in DART? chenglou That's not how you do it on Dart Check here, under the section Events: http://www.dartlang.org/articles/improving-the-dom/ elem.onClick.listen( (event) => print('click!')); Also, you might find that being able to optionally declare our variable types makes working with events in Dart bliss. import 'dart:html'; import 'dart:math'; class MyApplication { MyApplication() {

Hightlight the ListView row when a contained UI element of row is touched

阅读更多关于 Hightlight the ListView row when a contained UI element of row is touched

问题 I want to enable the orange highlight that occurs when touching a listView row. If the onclick event was generated from the row itself, I can adjust the hightlight by setting the style of the listview. However in my case, the clicking event is generated by the TextView underneath with onclick event attached to it. When touch event occurs, Listview isn't aware of clicking is happening. It doesn't receive focused or pressed event. Is there bubbling or capturing technique I could use like Flex
