javascript - 如何检索函数输入 javascript

Question

我有以下代码，可以在 asp.net 中生成动态创建的图像按钮和面板:-

Panel panBlocks = new Panel();
panBlocks.ID = "PanBlockQuestionID" + recordcount.ToString();
panBlocks.Width = 1300;
panBlocks.Height = 50;
panBlocks.BackColor = Color.Pink;

ImageButton cmdBlocks = new ImageButton();
cmdBlocks.ImageUrl = "~/Images/block3.png";
cmdBlocks.ID = "lblImg" + recordcount.ToString();
cmdBlocks.Attributes["class"] = "liQuestionsLabel2";
cmdBlocks.Width = 30;
cmdBlocks.Attributes.Add("OnMouseOver", "showPanel(" + "CPH_Body_" + panBlocks.ClientID.ToString() + ")");
cmdBlocks.Attributes.Add("OnMouseOut", "hidePanel();");

li.Controls.Add(cmdBlocks);                
li.Controls.Add(panBlocks);

当我将鼠标悬停在图像上时，我希望它显示特定的面板。我已添加 "CPH_Body_"+ panBlocks.ClientID.ToString() 作为属性。

我有以下 JavaScript 代码:

function showPanel(PanelID)
{
   document.getElementById("CPH_Body_liQuestions1").style.height = "40px";
}

如何在 javascript 中检索 PanelID，因为它看起来像一个数组。我需要检索它，以便我知道要显示哪个面板。

IIUC(!!):

更改此:

cmdBlocks.Attributes.Add("OnMouseOver", "showPanel(" + "CPH_Body_" + panBlocks.ClientID.ToString() + ")");

致:

cmdBlocks.Attributes.Add("OnMouseOver", "showPanel('" +  panBlocks.ClientID.ToString()   + "')");

并更改此:

function showPanel(PanelID)
{
   document.getElementById("CPH_Body_liQuestions1").style.height = "40px";
}

至

function showPanel(PanelID)
{
   document.getElementById(PanelID).style.height = "40px";
}
