求救大俠關(guān)于winfrom嵌套html 調(diào)用js問(wèn)題

至尊寶的傳說(shuō) 2018-07-22 10:04:20

js 代碼由于是原型的調(diào)用無(wú)法完成代碼：我也把 oGthinkrace賦值給 window.tk=oGthinkrace；后臺(tái)也調(diào)用不了后臺(tái)代碼： var ele = webBrowser.Document.GetElementById("map_canvas"); if (ele != null) { object ss = ele.InvokeMember("div.Obj.Locate", new object[] { "abcdee1111" }); }
