...; }); $("[draggable='true']").mousedown(function(e){ isDragging = true; mouseX = e.pageX; mouseY = e.pageY; scrollX = $(window).scrollLeft(); scrollY = $(window).scrollTop(); e.preventDefault(); }); }); 以上代码展示了如何让用jQuery完成拖拽兼容滚动条的效果。当用户按下鼠标左键并移动时，页面会反馈并滚动。必要的计算出通过$（window）.scrollTop（）和$（window）.scrollLeft（）完成。当用户释放鼠标左键时，拉动被停止。 可以为元素增加特性'draggable="true"'以激活拖拽机能。在mousedown事件处理程序中，程序会存储此刻的滚动位置和鼠标位置。在mousemove事件处理程序中，程序计算出出鼠标在页面上的移动距离，并让用$（window）.scrollTop（）和$（window）.scrollLeft（）函数来滚动页面。 通过上述代码，我们可以轻易地完成拖拽兼容滚动条的机能，为用户提供更佳的页面让用体验。

...的功能，通过其内置的draggable方法，使得创建可拖拽组件变得更加简单。 Draggable , 在JQuery库中，draggable是一个功能插件，它可以赋予HTML元素（如输入框）拖放的能力。当设置一个元素为draggable时，用户可以通过鼠标对元素进行拖拽，并在页面上自由移动该元素。结合文章语境，在实现按钮拖拽生成输入框的过程中，draggable方法被用来确保新创建的输入框具备拖拽调整位置的功能。 Web Components , 虽然本文未直接提到Web Components，但在现代前端开发领域中，这是一个重要的概念，有助于理解不同技术框架下实现类似功能的方式。Web Components是W3C提出的一种Web标准化技术，允许开发者自定义可重用的UI组件，每个组件拥有独立的视图（Shadow DOM）、行为和样式。相较于JQuery的插件方式，Web Components提供了一种原生的、更为模块化的组件化解决方案，可用于构建更加复杂的拖拽式交互界面。

...y="index" draggable="true" @dragstart="dragStart(index)">{ { item.content } } </div> 然后，在Vue的methods中设定拖放相关的函数。在这个例子中，dragStart函数用于设定被拖曳时的动作。比如： methods: { dragStart(index) { this.draggedItemIndex = index; } } 最后，在被拖曳组件的外部组件（通常是一个容器组件）上添加dragover和drop触发器。在dragover触发器中，需要使用event.preventDefault()函数来保证被拖曳组件可以被安放到指定的容器中。在drop触发器中，需要调用Vue实例中设定的drop函数来处置被拖放组件的最终位置。比如： computed: { containerStyle() { return { height: this.itemHeight + 'px' }; } }, methods: { drop() { const droppedItemIndex = this.draggedItemIndex; const items = [...this.items]; const draggedItem = items.splice(this.draggedItemIndex, 1)[0]; items.splice(this.droppedItemIndex, 0, draggedItem); this.items = items; }, dragOver(index, event) { event.preventDefault(); this.droppedItemIndex = index; } } 通过这种方式，Vue同级拖拽完成了对Web页面上组件的拖放操控，使使用者界面更加友好和易于使用。

...cal. With draggable, fully configurable nodes. Enhanced radar charts With stacked column, bands, axes, and other dramatic enhancements, radar charts are now way more useful. Treemaps Completely zoomable, multi-level, highly configurable. Heatmaps Automatically build heat-maps, with custom axes, color ranges, and awesome new interactive Heat Legend. Create heatmaps using colors, or point size or both. Universal and flexible heat rules allow attaching any value in data to any property or properties on any element. Chord diagrams Visualize your 2-way relational data in a neat circular Chord diagrams. We do have different variations of the classic diagram: Chord, Chord directed, and Chord non-ribbon. True funnel charts amCharts 5 offers true Funnel charts the way they were meant to be. Slice’s area size represents the value, so each step’s influence on overall volume reduction is more prominent than with basic funnels. Trapezoid form can also be configured to further emphasize reduction. Complete it with other visual elements, like fully configurable slice lines, multiple series support, togglable legends, and many many more options. Customizable beauty built-in Powerful theme engine amCharts 5 comes with a bunch of beautiful themes as well as a super flexible theme engine, which you can use. We devised a CSS-like rule-based theme targeting system in themes. Using, creating, customizing themes or standalone rules has never been so easy. The new system allows applying defaults to elements based on their type, features, or position in a virtual element tree. Fresh new look Default looks designed to look fresh, like something out of tomorrow. Carefully selected color schemes and default settings were specifically chosen to make the charts stand out. Silk-smooth animations Every setting – colors, positions, sizes, opacity, and many more – is animatable to ensure smooth transitions. No choppy, stepped animations – everything is fluid, including zoom and toggling of series and other items. Flexibility Element templates Most elements are created using templates: a collection of default settings, events, and adapters. Changing template automatically propagates changes to actual elements, making it easy to do batch updates. Everything’s configurable Numerous configuration options allow inventive uses, bordering on new chart types. Angles, colors, positions, radii, a-n-y-t-h-i-n-g can be set to bend classic and new chart types exactly the way you need them. Element states Easily change how an element looks like under different circumstances, e.g. on some interaction, hover, click, or related to data (eg. column look if a value is down). The engine will automatically apply the required properties as needed, animating between old and new values smoothly. Create and apply custom states via the API. Multi-type multi-axis support Add any number of axes of any type. Create overlaid comparison of different time scales. Use any mix of dimensional values: numbers, dates, categories, or duration. Adapters “Adapters” functionality allows plugging in custom code to dynamically override just about any setting or data value. Text formatting All text labels – tooltips, axis labels, titles, etc. – now support rich text formatting options, like changing colors, font weight, or applying just about any styling option from the CSS arsenal. In addition to formatting support, labels can now contain in-line placeholders for real data, with the ability to apply custom formatting to values. Accessibility & Interactivity Accessibility Accessibility was riding shotgun when amCharts 5 was being developed. All interactive elements are TAB-selectable, with customizable roles, order, and screen-reader texts. Everything that can be moved by touch or mouse, can be moved by keyboard. Everything that can be clicked or toggled, can be interacted with with keyboard, too. Touch support Charts have been designed to work with touch devices out-of-the-box. They will work not only on phones or tablets, but also touch capable computers. Under the hood Built with TypeScript Supports strong type and error checking in TypeScript applications. Enjoy code completion, error checking and dynamic help popups in major IDEs. Full support for TypeScript and ES6 modules. 100% for JavaScript Can be fully used in any vanilla JavaScript application. amCharts 5 does not use or rely on globals, external frameworks or 3rd party libraries. Universal rendering engine Can be used to build dynamic, interactive Canvas-based interfaces and applications. Add various elements to the screen, make them interactive, with a few lines of code. Make them clickable, draggable, hoverable, using built-in interactivity functionality. Our universal layout engine will place, size and arrange elements according to set rules. 本篇文章为转载内容。原文链接：https://blog.csdn.net/john_dwh/article/details/127460821。 该文由互联网用户投稿提供，文中观点代表作者本人意见，并不代表本站的立场。 作为信息平台，本站仅提供文章转载服务，并不拥有其所有权，也不对文章内容的真实性、准确性和合法性承担责任。 如发现本文存在侵权、违法、违规或事实不符的情况，请及时联系我们，我们将第一时间进行核实并删除相应内容。
