winform中执行JS代码使用 webBrowser1.Document.InvokeScript("方法名称");
在JS中执行winform的方法需要引用 using System.Security.Permissions
并且在在 命名空间中添加：
[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
[System.Runtime.InteropServices.ComVisibleAttribute(true)]
html的内容为：
1 <!DOCTYPE html> 2 <html> 3 <head> 4 <style type="text/css"> 5 body, html,#allmap {width: 100%;height: 100%;overflow: hidden;margin:0;} 6 #l-map{height:100%;width:78%;float:left;border-right:2px solid #bcbcbc;} 7 #r-result{height:100%;width:20%;float:left;} 8 </style> 9 <script type="text/javascript" src="http://api.map.baidu.com/api?v=1.5&ak=密匙"></script> 10 <title></title> 11 </head> 12 <body> 13 <input id="mouselng" type ="hidden" /> 14 <input id="mouselat" type = "hidden"/> 15 16 <div id="allmap"></div> 17 </body> 18 </html> 19 <script type="text/javascript"> 20 var map = new BMap.Map("allmap"); 21 var marker_num = 0; 22 function loadScript() { 23 map.centerAndZoom("重庆", 12); 24 map.enableScrollWheelZoom(true); 25 } 26 function PUTANDSEND() { 27 map.addEventListener("rightclick", putAndsend); 28 } 29 function putAndsend(e) { 30 //放标注 31 var p1 = new BMap.Point(e.point.lng, e.point.lat); 32 var marker = new BMap.Marker(p1); //将标注的图标改为小汽车 33 map.addOverlay(marker); 34 marker_num++; //标注索引，这个是个全局变量 35 var whichCar = window.external.setWhichCar(); 36 var label = new BMap.Label(whichCar + "号车-坐标" + marker_num + ":" + 37 "(" + e.point.lng + "," + e.point.lat + ")", { offset: new BMap.Size(20, -10) }); 38 marker.setLabel(label); 39 //给WINFORM传值 40 window.external.PutIntotextBox(marker_num, whichCar, e.point.lng, e.point.lat); 41 42 } 43 window.onload = loadScript; 44 </script>
winform中cs的内容为：
1 using System; 2 using System.Windows.Forms; 3 using System.Security.Permissions; 4 5 namespace TestJS 6 { 7 [PermissionSet(SecurityAction.Demand, Name = "FullTrust")] 8 9 [System.Runtime.InteropServices.ComVisibleAttribute(true)] 10 public partial class Form1 : Form 11 { 12 public Form1() 13 { 14 InitializeComponent(); 15 } 16 17 private void Form1_Load(object sender, EventArgs e) 18 { 19 string path = Application.StartupPath + @"\1.html"; 20 21 path = path.Replace("\\", "/"); 22 path = "file://" + path; 23 webBrowser1.Url = new Uri(path); 24 webBrowser1.Document.InvokeScript("loadScript"); 25 webBrowser1.ObjectForScripting = this; 26 } 27 private void btnPutMarker_Click(object sender, EventArgs e) 28 { 29 webBrowser1.Document.InvokeScript("PUTANDSEND"); 30 } 31 //得到Radiobutton的值 32 public string setWhichCar() 33 { 34 if (radioButton1.Checked) 35 return "1"; 36 if (radioButton2.Checked) 37 return "2"; 38 if (radioButton3.Checked) 39 return "3"; 40 return "Erro"; 41 } 42 public void PutIntotextBox(object markerIndex, object carNumber, object JSlng, object JSlat) 43 { 44 text_index.Text = markerIndex.ToString(); 45 text_num.Text = (string)carNumber; 46 text_lng.Text = JSlng.ToString(); 47 text_lat.Text = JSlat.ToString(); 48 string sql = "insert into 汽车轨迹数据 values ('" + text_num.Text + "','" + text_index.Text + "','" + text_lng.Text + "','" + text_lat.Text + "','" + DateTime.Now.ToString() + "')"; 49 //MessageBox.Show(sql); 50 51 } 52 } 53 }
执行结果如图所示
