Question

Getting the value of a repeater label in JavaScript can be achieved by following these

Here is my javascript code:

function btnEditClick() {
    alert(document.getElementById('<%=LblRefPhyID.ClientID %>').value);          
}

<asp:Repeater ID="repeaterRefPhysicianList" runat="server">
  <ItemTemplate>
    <tr onclick="selectRow(this);">
      <td class="csstablelisttd" style="display: none;">
        <asp:Label ID="LblRefPhyID" runat="server" Text='<%#Eval("Ref_Phy_ID")%>'></asp:Label>  
      </td>

In the Edit button's clientclick event, I need to pass RefphyId to another page. How can I achieve this?

c#javascript asp.net

Answer №1

This component functions as a repeater, meaning that the content within the ItemTemplate will be duplicated for every item in your data collection.

However, there is a slight complication with IDs needing to be unique. When you assign an ID like LblRefPhyID to your asp:Label, ASP.NET takes care of generating unique IDs for each instance of the repeater in the HTML output. These generated IDs are based on the original value provided, but they won't match exactly, so a regular document.getElementById() call outside of the repeater won't work as expected.

To address this challenge, it's essential to incorporate code that accounts for these dynamically generated IDs. You might consider using JavaScript to cache the IDs using `LblRefPhyID.ClientID`, or implementing dynamic processing with events like `onclick`.

UPDATE

In addition, @Pointy's point about the fact that label elements do not have values, only inner HTML, is accurate. It's important to acknowledge and appreciate correct responses rather than downvoting them unnecessarily.

To improve the functionality, consider using a CSS class instead of an id and binding elements' click events by class name. Below is an example implementation using jQuery:

$(document).ready(function(){
  // Bind click event on elements with class 'lblRef'
  $('.lblRef').on('click', function(){
    alert($(this).text());
   });
});

Here's how you can implement this in an ASP.NET page:

<asp:Label CssClass="lblRef" runat="server" Text='<%#Eval("Ref_Phy_ID")%>'></asp:Label>

When it comes to HTML, the <label> elements do not possess a designated "value". However, they do contain text:

alert(document.getElementById('<%=LblRefPhyID.ClientID %>').innerHTML);

One efficient method is to analyze the pattern of the generated IDs by the repeater on the client side, which can then be utilized to extract the label values using innerHTML. For example, in your scenario, the generated ID could follow this format:

repeaterRefPhysicianList_LblRefPhyID_01

and continue for each row in the source.

By leveraging this understanding with innerHTML, you can retrieve the label values effectively. Essentially, simply examine your HTML page to determine the subsequent steps :)
