问题 So I'm trying to use these CSS3 buttons taken from: http://lab.simurai.com/buttons/ Here is the button I've created: http://utvecklingspunkten.se/glist/admin/addGuests/button.php As the title states the buttons function doesn't always fire when clicked on. There are some spots/pixels which doesn't seem to register the click (which is weird since the button still does change its appearance when clicked on these sweet spots - but it's not firing its onClick function). So here is the code I use

问题 At the end of my submit button click handler, Resharper warns that, "Not all code paths return a value." What value would it be expecting from an event handler? In deference to full disclosure, this is that event handler: $("#submit_button").click(function() { // http://stackoverflow.com/questions/18192288/how-can-i-compare-date-time-values-using-the-jqueryui-datepicker-and-html5-time var begD = $.datepicker.parseDate('mm/dd/yy', $('#BeginDate').val()); var endD = $.datepicker.parseDate('mm

阅读更多关于 Chrome doesn't fire click event for SVG element (Firefox does)

问题 I observe inconsistency/bug in handling click event among various browsers (Chrome, Edge, Firefox). In my JavaScript library that uses SVG I create clickable and draggable rectangles. When I run my snippet in Chrome browser the click event is not firing if 2 or more elements are present on canvas. To check this you need to create at least 2 rectangles on canvas.

1:事件与原生事件类型 react中式on+首字母大写的事件名例如onClick 如图只需要on以后常用的事件都会提示出来 2:在Content.js中新建一系列的按钮来对事件进行学习 2.1 普通的函数绑定 <button onClick={function(){alert('6666')}}>按钮1</button> 2.2 箭头函数的绑定 <button onClick={()=>{ alert("7777"); }}>按钮2</button> 2.3 箭头函数带参数 <button onClick={(e)=>{ e.target.style.color="red"; }}>按钮3</button> 2.4 页面部分 <button onClick={ this.show }>按钮4</button> 在render的上面定义一个函数细节看alert中的提示 constructor(props){ super(props); this.state={ num:10 } //this.show9 = this.show9.bind(this); } show(){ alert("按钮4被点击但是里面this会脱离上下文关系"); alert(this.state.num);//报错 this是undefined } 2.5 利用箭头函数对this指向进行加强
