如何在 javascript 中调用控件的 WebMethod

发布于 2024-10-14 08:25:29 字数 757 浏览 7 评论 0原文

我正在尝试使用 javascript 为网页中的控件调用 WebMethod (GetData())。

<script type="text/javascript">
    $(document).ready(function () {
        //this selector needs fixed
        $('<%= Control1.ClientID %>').GetData();
    });
</script>

<tel:RadScriptManager ID="RadScriptManager1" runat="server" />
<tel:RadAjaxPanel ID="RadAjaxPanel1" runat="server" LoadingPanelID="RadAjaxLoadingPanel1">
    <uc1:Control ID="Control1" runat="server" />
</tel:RadAjaxPanel>

uc:Control 代码：

    [WebMethod()]
    [ScriptMethod()]
    protected void GetData()
    {
        //stuff happens here
    }

我不知道要使用哪种选择器。我的页面上有多个控件，我想在不同的时间调用它们。我使用什么类型的选择器或什么命令来运行此 WebMethod？

I'm trying to call a WebMethod (GetData()) for a control in a web page using javascript.

<script type="text/javascript">
    $(document).ready(function () {
        //this selector needs fixed
        $('<%= Control1.ClientID %>').GetData();
    });

<tel:RadScriptManager ID="RadScriptManager1" runat="server" />
<tel:RadAjaxPanel ID="RadAjaxPanel1" runat="server" LoadingPanelID="RadAjaxLoadingPanel1">
    <uc1:Control ID="Control1" runat="server" />
</tel:RadAjaxPanel>

The uc:Control code:

    [WebMethod()]
    [ScriptMethod()]
    protected void GetData()
    {
        //stuff happens here
    }

I can't figure out what kind of selector to use. I have multiple controls on the page, and i want to call them at different times. What kind of selector or what command do I use to run this WebMethod?

据我了解，不可能在子/用户控件上调用 webmethod/pagemethod。

如果您要将此 Web 方法移至父级 aspx，则需要执行以下操作：

jQuery.ajax({
  type: 'POST',
  contentType: 'application/json; charset=utf-8',
  data: '{}',
  dataType: 'json',
  url: 'MyPage.aspx/SomePageMethod',
  success: function(result){
    alert(result);
  }
});

It is my understanding that it is not possible to call a webmethod/pagemethod on a child/user control.

If you were to move this web method to the parent aspx, you would need to do something like this:

jQuery.ajax({
  type: 'POST',
  contentType: 'application/json; charset=utf-8',
  data: '{}',
  dataType: 'json',
  url: 'MyPage.aspx/SomePageMethod',
  success: function(result){
    alert(result);
  }
});

这将选择 ID 以您传递给它的 ControlID 结尾的元素，从而忽略 asp.net 在您的控件 ID 前面添加的任何额外文本

$("[id$='_ControlIDHere']")

编辑：我可能误解了这个问题，但如果您实际上只是在寻找选择器来获取对您的控件的引用，然后我的方法就可以工作

This will select the element with an ID that ends with the ControlID you pass to it, thus ignorning any extra text that asp.net prepends to your control ID's

$("[id$='_ControlIDHere']")

EDIT: I may have misunderstood the question but if you are in fact just looking for a selector to get a reference to your controls then my method will work
