__doPostback来自Javascript给出了错误的参数 [英] __doPostback from Javascript gives wrong Argument

问题描述

亲爱的所有人，
我正在使用波纹管代码从JavaScript回发，但似乎我没有得到我通过的论据.

Dear All,
I am using bellow code to postback from JavaScript but it seems I am not getting the argument i pass.

public string postBackStr; //Defined in class

postBackStr = Page.ClientScript.GetPostBackEventReference(this, "myArgument"); //Defined in Page Load

textBox = cmbCo.FindControl("TextBox") as TextBox;
if (textBox != null)
{textBox.Attributes.Add("onblur", "return getMinistryCode(this);"); // This is In Render
}

在javascript中，我具有功能

In javascript i have the function

function getMinistryCode(txt) {
var cmbSDURN = document.getElementById(document.getElementById('<%= this.cmbSDURN.ClientID %>').id + "_HiddenField");
if (cmbSDURN.value == 0) {
   alert('Please Select SDURN');
   <%= postBackStr %>
 }
 }

回发发生了，但是我正在获取cmbCo ClientID，让我提到cmbCo是Ajax 3.5 ComboBox，并且我正在分配onblur.

参数值的代码是

The postback occurs but i am getting cmbCo ClientID, let me mention that cmbCo is Ajax 3.5 ComboBox and I am assigning onblur.

And the code for argument value is

if (Page.IsPostBack)
        {
            string arg = Request["__EVENTTARGET"].ToString();
            Response.Write(arg);
}

正如我所说的arg返回cmbCo的clientID一样，如何获取通过客户端脚本传递的参数?

我找到了贝娄的解决方案.

As i stated the arg return the clientID of cmbCo, how can i get the argument which i am passing through Client Script?

I found the solution by bellow.

if (Page.IsPostBack)
        {
            string arg = Request["__EVENTTARGET"].ToString();
            if (arg.Equals(cmbSDURN.ClientID.Replace('_', '$')))
            {

推荐答案

'))) {

'))) {

您应该能够使用
获取Argument值

You should able to get the Argument values using

string arg = Request["__EVENTARGUMENT"].ToString();
