.NET ------ 点击新增按钮进行传值赋值

1、不通过地址栏进行传值，

载入时进行判断如果没有赋值就返回   btnSearch

    private string _buttonClick
    {
        get
        {
            if (Request["btn"] == null)
                return "btnSearch";
            else
                return Request["btn"].ToString().Replace(" ", "");
        }
    }

在进行 调用   一个用于解析不同浏览器值得方法  GetSrcriptContentByClick，因为不同浏览器的前置不一样所以这个不怎么好

        if (_buttonClick == "btnSearch")
                {
                     script += base.GetSrcriptContentByClick(_buttonClick);
                }
                else
                {
//地址栏传值进行控制
                     script += "parent.document.getElementById('" + _buttonClick + "').click();";
                }

GetSrcriptContentByClick 这个方法放在了该界面继承的 pageBase 界面中

    /// <summary>
    /// 弹出窗体选择后返回的脚本
    /// </summary>
    /// <param name="sContent"></param>
    /// <param name="sValue"></param>
    /// <returns></returns>
    public string GetSrcriptContentByClick(string sContent)
    {
        string s = "if(parent.document.getElementById('ctl00_ContentPlaceHolder1_" + sContent + "') ){parent.document.getElementById('ctl00_ContentPlaceHolder1_" + sContent + "').click();}";
        s += "else if(parent.document.getElementById('ctl00$ContentPlaceHolder1$" + sContent + "')){parent.document.getElementById('ctl00$ContentPlaceHolder1$" + sContent + "').click();}";
        s += "else if(parent.document.getElementById('ContentPlaceHolder1_" + sContent + "')){parent.document.getElementById('ContentPlaceHolder1_" + sContent + "').click();}";
        s += "else if(parent.document.getElementById('" + sContent + "')){parent.document.getElementById('" + sContent + "').click();}";
        return s;
    }

2、直接从后端送一段话进行控制   

<input id="btnAdd" type="button" value="新增" class="ttbtn" onclick="javascript: WebDialogLoad('新增', 800, 600, 'CClass_edit_win.aspx?pwidth=780&pheight=480&edit=add')" />
&nbsp;

改变成，<%=    相当于 Response.Write   服务端向客户端送一段话

<input id="btnAdd" type="button" value="新增" class="ttbtn" onclick="javascript: WebDialogLoad('新增', 800, 600, 'CClass_edit_win.aspx?pwidth=780&pheight=480&edit=add&btn=<%=btnSearch.ClientID%>')" />
&nbsp;

将之前的注释掉，直接传递参数
