安卓平台的浏览器 touchend 事件触发失效?
点击应该触发 touchstart 和 touchend 两个事件,但是安卓手机中并没有触发 touchend,请问如何解决这个问题?
回复内容:
touch事件在手机浏览器上存在莫名的兼容性问题, 会导致touchend事件不触发!http://code.google.com/p/android/issues/detail?id=19827
Working with touch events
On Android ICS if no preventDefault is called on touchstart or the first touchmove, further touchmove events and the touchend will not be fired.
As a workaround we need to decide in the first touchmove if this is a scroll (so we don’t call preventDefault) and then manually trigger touchend.
如果你没有太多顾虑(关于scroll的), 请在touchstart的handle中使用event.preventDefault(), 即可让touchend事件正常触发 感谢啊,莫名其妙的问题 最近几天开发也碰到了这个问题,项目要模拟一个app的向下拉动加载效果。我的解决办法是在touchmove中添加e.preventDefault(),将浏览器默认的滑动惯性去掉,这样就不会干扰到touchend事件的触发,然后再手写滑动效果,另外需要注意判定是否有滑动产生,避免干扰默认的点击效果触发:
var x, y, z;
var slideCouter = 1; var hasMoved = false; var checking = false; var hasMore = true; $(document).on('touchstart', function (e) { z = $(document).scrollTop(); x = event.targetTouches[0].pageY; }).on('touchmove', function (e) { e.preventDefault(); hasMoved = true; y = event.targetTouches[0].pageY; z += x - y; $(document).scrollTop(z); }).on('touchend', function (e) { if (x - y > 200 && !checking && hasMoved && hasMore) { checking = true; slideCouter++; $('.login').removeClass('none'); $.ajax({ url: "<?php echo $this->createUrl('/teacher/categoryMore');?>", type: "get", data: { "keyword": '<?php echo $keyword;?>', "page": slideCouter }, cache: false, success: function (data) { completecall(data); } }); } hasMoved = false; }); ============== 目前别的方法都会有或多或少的弊端,该方法的弊端就是滑动惯性被取消,自己写的效果会不那么流畅,但还算比较好的解决这个兼容问题。
复制文本是什么状况 我也想知道 我也遇到了这个问题啊,需要顾虑scroll,阻止默认事件这个行不通,使用touchcancel这个在android4.4中会出现复制文本之类的,这个要怎么解决? @bo bo 我要顾虑scroll,怎么解决这个问题啊?

Running the H5 project requires the following steps: installing necessary tools such as web server, Node.js, development tools, etc. Build a development environment, create project folders, initialize projects, and write code. Start the development server and run the command using the command line. Preview the project in your browser and enter the development server URL. Publish projects, optimize code, deploy projects, and set up web server configuration.

H5 page production refers to the creation of cross-platform compatible web pages using technologies such as HTML5, CSS3 and JavaScript. Its core lies in the browser's parsing code, rendering structure, style and interactive functions. Common technologies include animation effects, responsive design, and data interaction. To avoid errors, developers should be debugged; performance optimization and best practices include image format optimization, request reduction and code specifications, etc. to improve loading speed and code quality.

The steps to create an H5 click icon include: preparing a square source image in the image editing software. Add interactivity in the H5 editor and set the click event. Create a hotspot that covers the entire icon. Set the action of click events, such as jumping to the page or triggering animation. Export H5 documents as HTML, CSS, and JavaScript files. Deploy the exported files to a website or other platform.

H5 is not a standalone programming language, but a collection of HTML5, CSS3 and JavaScript for building modern web applications. 1. HTML5 defines the web page structure and content, and provides new tags and APIs. 2. CSS3 controls style and layout, and introduces new features such as animation. 3. JavaScript implements dynamic interaction and enhances functions through DOM operations and asynchronous requests.

Yes, H5 page production is an important implementation method for front-end development, involving core technologies such as HTML, CSS and JavaScript. Developers build dynamic and powerful H5 pages by cleverly combining these technologies, such as using the <canvas> tag to draw graphics or using JavaScript to control interaction behavior.

H5 pop-up window creation steps: 1. Determine the triggering method (click, time, exit, scroll); 2. Design content (title, text, action button); 3. Set style (size, color, font, background); 4. Implement code (HTML, CSS, JavaScript); 5. Test and deployment.

H5 (HTML5) is suitable for lightweight applications, such as marketing campaign pages, product display pages and corporate promotion micro-websites. Its advantages lie in cross-platformity and rich interactivity, but its limitations lie in complex interactions and animations, local resource access and offline capabilities.
