使用javascript访问隐藏字段值 [英] Access hidden field value using javascript

问题描述

你好朋友，

谁能告诉我，我怎样才能使用javascript获取隐藏字段的价值。



这是aspx代码

Hello Friends,
Can anyone tell me, how I can get the value of hidden field using javascript.

Here is aspx code

<asp:LinkButton ID="lnkDelete" runat="server" CommandName="Delete" CssClass="delbutton" CommandArgument='<%#Eval("noticeid") %>'>Delete
<asp:HiddenField ID="hfID" Value='<%#Eval("noticeid") %>' runat="server" />

这里我在尝试什么，我对隐藏领域具有约束力。使用这个值我将使用Json删除记录。



我试过以下JavaScript

Here what I'm trying, I'm binding value to hidden field. Using this value I'm going to delete record using Json.

I tried following JavaScript

function funDelete() {
            alert("Start");
            if (confirm("Do you want to delete this record?")) {
                alert("Step 1");
                try {
                    $(document).ready(function() {
                        $('#lnkDelete').click(function() {
                            alert("Ready");
                        });
                        
                    });
                    //GET ID OF RECORD TO BE DELETED
                    var id = document.getElementById('<% =hfID.ClientID %>').value;
                    //$('#hfID').val();
                    
                    alert("ID:" + id);
                    $.ajax({
                        type: "POST",
                        url: "QCNotice.aspx/deleteComment",
                        data: "{'args':'" + id + "'}",
                        contentType: "application/json; charset=utf-8",
                        dataType: "json",
                        success: function() {
                            alert("IN");
                            row.css("background-color", "Red");
                            row.fadeOut(500, function() {
                                row.remove();
                            });
                        },
                        error: function(event, request, settings) {
                            alert("Ajax Error");
                        }
                    });
                }
                catch (e) {
                    alert("Error:" + e.message);
                }
            }
            return false;
        }

错误说：重载解析失败，因为没有可访问的'Write'可以用这些参数调用



任何想法，我哪里出错？



提前致谢

It gives error saying: Overload resolution failed because no accessible 'Write' can be called with these arguments

Any idea, where I'm going wrong??

Thanks in advance

推荐答案

（document）.ready（function（）{

(document).ready(function() {

（'＃lnkDelete' ）.click（function（）{
alert（Ready）;
}）;

}）;
//要删除的记录的GET ID
var id = document.getElementById（'<％= hfID.ClientID％>'）。value;
//

('#lnkDelete').click(function() { alert("Ready"); }); }); //GET ID OF RECORD TO BE DELETED var id = document.getElementById('<% =hfID.ClientID %>').value; //

（'＃hfID'）。val（）;

alert（ID：+ id）;

('#hfID').val(); alert("ID:" + id);
