JQuery更改了样式，但是服务端无法更新. [英] JQuery to change the style , but service side can not be updated.

问题描述

下面的JQuery将更新UI中显示或隐藏的两个单元格:

Hi,
Below JQuery is going to update two cells in UI show or hide:

<pre lang="xml">function DisplayExistingStatus() {
    if($("#<%=IsNew.ClientID %>").val() == $("#<%=hfIsNew.ClientID %>").val()) {
        $("#<%=tdLblECS.ClientID %>")[0].style.display = "";
        $("#<%=tdECS.ClientID %>")[0].style.display = "";
        ValidatorEnable($("#<%= rfvExistingCollStatus.ClientID %>")[0], true);
        //ValidatorEnable(document.getElementById("<%= rfvExistingCollStatus.ClientID %>"), true);
    } else {
        $("#<%=tdLblECS.ClientID %>")[0].style.display = "none";
        $("#<%=tdECS.ClientID %>")[0].style.display = "none";
        ValidatorEnable($("#<%= rfvExistingCollStatus.ClientID %>")[0], false);
        //ValidatorEnable(document.getElementById("<%= rfvExistingCollStatus.ClientID %>"), false);
    }
}

在页面加载事件中，显示/隐藏从DB检索的记录:

And in page load events, do display/hide with the record which retrieve from DB:

if (this.IsNew.SelectedValue != ViewState["IsNew"].ToString())
{
    this.tdECS.Attributes.Add("style", "display:none");
    this.tdLblECS.Attributes.Add("style", "display:none");
    this.rfvExistingCollStatus.Enabled = false;
}

为了在隐藏时将一个子列更新为null，我编写了一个检查函数:

In order to update one sub column to null when it was hide, I have written one check function:

if ((this.Master.FindControl("Content").FindControl("tdECS") as HtmlTableCell).Style.Value == "display:none")
    collObj.ExistingCollStatus = null;

但是，更改UI后，无法更新此样式.
等待帮助

However, this style can not be updated when UI have been changed.
Wait for help

推荐答案

(#<％= IsNew.ClientID％>").val()==

("#<%=IsNew.ClientID %>").val() ==

(#<％= hfIsNew.ClientID％>").val()){

("#<%=hfIsNew.ClientID %>").val()) {

(#<％= tdLblECS.ClientID％>")[ 0] .style.display =";

("#<%=tdLblECS.ClientID %>")[0].style.display = "";
