网页上有一个元素没有onclick事件，只有onmousedown,onmouseup事件，怎么在webborwser里模拟右键点击这个元素？
楼主：
首先你必须确保网页中有右键的那个js，比如我的代码（div作为例子）：
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<script>
function DivFun()
{
document.getElementById("mydiv").oncontextmenu = function ()
{
alert("您点击了右键!");
return false;
};
}
</script>
</head>
<body onload="DivFun()">
<div id="mydiv" style="border:groove;border-width:thick;width:100%;height:100%">
<br />
<br /><br />
<br /><br />
<br /><br />
<br /><br />
<br />
</div>
</body>
</html>
其次，用Windows API把鼠标移动到指定的div区域，模拟右键：
【Form结构】
namespace CSharp
{
partial class Form1
{
/// <summary>

private System.ComponentModel.IContainer components = null;
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows Form Designer generated code

this.SuspendLayout();

this.button1.TabIndex = 1;
this.button1.Text = "模拟右键";
this.button1.UseVisualStyleBackColor = true;
this.button1.Click += new System.EventHandler(this.button1_Click);

this.Name = "Form1";
this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
this.Text = "Form1";
this.Load += new System.EventHandler(this.Form1_Load);
this.ResumeLayout(false);
}
#endregion

private System.Windows.Forms.Button button1;
}
}
