由 主宰稳场 提交于 2019-12-20 05:37:29
问题 Basically, so far I've just got an add and minus button which will change the value of a TextView. I followed the second example under "Event Listeners" on http://developer.android.com/guide/topics/ui/ui-events.html The problem is I get 4 errors when I go to compile, I don't see what I'm doing wrong? Please can someone point out if there is anything wrong, or show me a simpler way please. Thank you for your time. Here's the errors: /home/alex/NetBeansProjects/GolfScoreCard/src/com/alex

问题 I thought that this was easier… I have a asp:hyperlink control, with target=”_blank” , pointing to the file I want the user to download. My plan is to track the number of times, the users click on this link. I thought in placing it in ajax update panel, to catch the postback and avoid full page refresh. However, hyperlink doesn’t have a onClick method. On the other hand I could use a linkbutton , which has a onClick built in. But It’s harder to make the file open in a new window… and I would

问题 Let's say I have a simple list: <ul> <li class="notClicked">1</li> <li class="notClicked">2</li> <li class="notClicked">3</li> </ul> Can I onClick of one "li" change styles of all li 's except the one clicked? So if I click "li" number 2, then the list will look like: <ul> <li class="notClicked">1</li> <li class="clicked">2</li> <li class="notClicked">3</li> </ul> So if I click on first "li" then it will have clicked class, while others will be notClicked. In case you want to play with it,

ASP.NET LinkButton OnClick Event Is Not Working On Home Page

问题 I have a user control that handles logging a user in to my site. This user control is placed in the upper right corner of all pages as a Quick Login Box. The problem I'm having is that on my production server, the LinkButton click events I have provided for logging in and reset are not firing the OnClick event after a postback. Its like it just forgets to do it. Normally this wouldn't be such an issue to debug, except that it does not happen when running in debug on localhost (nor when

react类方法的绑定

由 不羁岁月 提交于 2019-12-19 19:15:11
首先我们需要明白 什么是单向数据流？ 你通过onClick触发一个动作，再通过函数/类方法修改组件的state，最后通过render()方法再次运行来更新界面 class App extends Component{}不能完成this的自绑定，所以采用以下方式 官方推荐的方法 this.onClickMe = this.onClickMe.bind(this); 有参数时： onClick={()=>{this.onClickMe(1)}} 无参数时： onClick={this.onClickMe} 箭头函数类方法 onClickMe= () => { 　　console.log(this); } 通过箭头函数的特性，this绑定组件实例 来源： https://www.cnblogs.com/shiyujian/p/9441539.html
