拖拽后,地图直接消失了,而且右上角的坐标变成了NaN,NaN 后来经过测试发现,原来是自己封装有问题,坐标点一定要用parseFloat()转换下,但不清楚为什么页面刚开始加载的时候没有问题,总之能解决就好.代码如下: var centerXY = "121.5472412109375,29.88006591796875"; var centerObj = centerXY.split(','); var centerX = centerObj[0]; var centerY = ce
窗体界面部分如下: 鼠标的缩放功能需要手动在 OpertaionImg.Designer.cs 文件里面添加一句代码,具体代码如下: //picturePhoto显示图片的控件 this.picturePhoto.MouseWheel += new System.Windows.Forms.MouseEventHandler(this.picturePhoto_MouseWheel); 下面是窗体的后台代码: public partial class OpertaionImg : Form {
1. @echo off & setlocal enableDelayedExpansion set a= set /p a=Please drag your txt file for split: cls :: %% 两个百分号 不带文件名后缀 for %%k in (%a%) do set wjm=%%~nk 2. 调用call echo %~nx1 set /p a=Please drag your txt file for split: call :getname !a! :getnam
//拖拽要素 function dragFeature (_map,_dragEndCallback) { let selFeature = null; _map.on("pointerdrag", function (evt) { selFeature = _map.getFeaturesAtPixel(evt.pixel, function (feature) { return feature; }); }); let translate = new ol.interaction.
