C＃中的JavaScript问题 [英] JavaScript Problem In C#

问题描述

function SetPlan_Id(LblPlanId) {
            var PlanId = 'MainContent_GvGrid_' + LblPlanId;
            document.getElementById('<%= HPlanId.ClientID %>').innerHTML = document.getElementById(PlanId).innerHTML

这个函数在VB.NET中运行良好......但不是在C＃中。 。

因为我从这里生成了硬编码的id ....



那么C＃的解决方案是什么..



这个函数是代码背后的调用....

this function is Working Fine In VB.NET...But Not In C#..
Because I Generated Hard Coded id From Here....

So What is the solution For C#..

this Function Is Call at Code Behind....

protected void GvGrid_RowCreated(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                Label LblId = (Label)e.Row.FindControl("LblId");
                Panel pnl1 = (Panel)e.Row.FindControl("pnl1");
                string Id = LblId.ClientID;
                pnl1.Attributes.Add("onmouseover", "SetPlan_Id('" + Id + "');");
            }
        }

推荐答案

I think you don't need this part in javascript:
var PlanId = 'MainContent_GvGrid_' + LblPlanId;

因为你已经发送了lbl.ClientId作为参数...只需调用

document.getElementById（'<％= HPlanId.ClientID％>'）。innerHTML = document.getElementById（LblPlanId）.innerHTML



通常，您永远不希望为服务器端控件提供用于ID的硬编码字符串。如果你需要C＃版本（应该是相同的，真的，除了C＃是区分大小写的 - 最愚蠢的语言属性）你必须检查页面源并查看页面标签的id是什么已满载。





只是一个小抱怨：javascript一般不是关于C＃和VB.NET，它是客户端代码而另外两个是服务器端。

Since you're already sending lbl.ClientId as parameter...just call
document.getElementById('<%= HPlanId.ClientID %>').innerHTML = document.getElementById(LblPlanId).innerHTML

In general you never want to have hard-coded string for ID for server side controls. If you need C# version (should be the same, really, except C# is case sensitive - stupidest language property ever) you have to check the page source and see what is the id of the label once the page is fully loaded.


Just a minor gripe: javascript generally isn't about C# and VB.NET, it is client side code while other two are server side.

尝试使用LblId.Text而不是LblId.ClientId，因为LblId是放置在gridview内的服务器端控件。



protected void GvGrid_RowCreated（object sender，System.Web.UI.WebControls.GridViewRowEventArgs e）

{

if（e.Row.RowType == DataControlRowType.DataRow）

{

Label LblId =（Label）e.Row.FindControl（LblId）;

Panel pnl1 =（面板）e.Row.FindControl（pnl1）;

字符串Id = LblId.Text;

pnl1.Attributes.Add（onmouseover，SetPlan_Id（'+ Id +'）;）;

}

}

Try to use LblId.Text instead of LblId.ClientId as LblId is a server side control which placed inside the gridview.

protected void GvGrid_RowCreated(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label LblId = (Label)e.Row.FindControl("LblId");
Panel pnl1 = (Panel)e.Row.FindControl("pnl1");
string Id = LblId.Text;
pnl1.Attributes.Add("onmouseover", "SetPlan_Id('" + Id + "');");
}
}
