1. 小程序中canvas层级的概念 在微信小程序中,canvas 是一个原生组件,由客户端直接创建和渲染。由于这一特性,canvas 的层级在页面中是最高的,不受z-index属性的控制。这意味着,无论你将其他组件的 z-index 设置得多么高,它们都无法覆盖在 canvas 之上。这一特性在绘制图形、制作动画等场景中非常有用,但也可能...
需要注意的是建议把小的canvas放到上面,方法是设置两个canvas的z-index为不同的值,值大的在上面。
pane.style.zIndex=`${featureLayerStartZIndex + order}`; } } }, [order] ); Here you can see how it eventually looks like in the html structure: Eventually, the only layer that is on the very top will be the interactive one, it will cover the map completely. Other canvas layers won...
import { canvasMarkerLayer } from '@/hook/leaflet.canvasmarker'; // CanvasMarkerLayer 继承 L.Layer const layer: CanvasMarkerLayer = canvasMarkerLayer(options); options 的可选参数: 参数描述默认值 zIndex 图层DOM 元素的堆叠顺序 null collisionFlg 是否开启碰撞检测功能,默认不开启 false moveReset 在...
canvas.moveTo(object, index); object.moveTo(index); i hope this is what you want: http://jsfiddle.net/Kienz/RRv3g/ Z-index of in IE 9 problem, Here's how it should work: The red-outlined box should be hyperlinked and be the top layer. The cyan <canvas> should the next layer...
原理:使用canvas绘画DOM,转成图片 html2canvas:html2canvas 引入:html2canvas.min.js 1、使用dom把你要生成的海报组装好,如果当用户点击的时候在去展示海报的话,可以吧海报定位到 z-index:-1; 不要使用隐藏(如果隐藏的话是无法生成海报的)
zIndex 对应canvas的css z-index属性,当添加了多个CanvasLayer时,可以用于设置层叠顺序。 number - paneName CanvasLayer位于的覆盖物层级,例:paneName: floatPane。JSAPI把地图覆盖物分为了8个层级,顶层为floatPane, 低层为 vertexPane。可以通过 Map 实例的 getPanes() 方法,获取到8个层级的名称。 floatPane,...
draw(); layer.on('click tap', function(){ pieChart.playAnimate(); }); //饼状图 function PieChart(option) { var _this = this; if( !option ) { throw new Error('请初始化饼状图的参数'); } this.animageIndex = 0; this.init = function(otpion) { //饼状图数据:[{name:'',...
Each layer has 5 slider controls: Z-index: Adjusts the z position of the layer, a higher value will allow the layer to display over top of lower z-index value layers. Width: Adjusts the width of the layer in relation to the width of the canvas. If the canvas width is 640px, 100...
