Solution - Form Elements do not have Associated Labels
When form elements do not have associated labels, it can make it difficult for users to understand the purpose or context of those elements. Adding clear and descriptive labels is important for accessibility and usability. Here's a step-by-step guide on how to solve form elements do not have associated labels issue
Step 1. Identify the form elements without labels
Start by identifying the form elements that do not have associated labels in your we page. These elements could include text inputs, checkboxes, radio buttons, select dropdowns, or any other input fields in your web page.
Example in HTML
<input type="text" onkeyup="success()" maxlength="50" runat="server" tabindex="0" clientidmode="static" id="txtemail" name="useremail" class="input_text" onchange="return validateEmail(this);" data-message="Email can't be blank." />
Example in ASP.NET
<asp:DropDownList ID="DropDownListChapterTitle" runat="server" AutoPostBack="true" CssClass="CommonTextBoxStyle responsive_textbox" OnSelectedIndexChanged="DropDownListChapterTitle_SelectedIndexChanged" ValidationGroup="InsertChapter"> </asp:DropDownList>
Step 2. Determine the purpose of each form element
Understand the purpose of each form element and what information it is intended to capture. This will help you create appropriate labels in your web page.
Example in HTML
<input type="text" onkeyup="success()" maxlength="50" runat="server" tabindex="0" clientidmode="static" id="txtemail" name="useremail" class="input_text" onchange="return validateEmail(this);" data-message="Email can't be blank." />
The purpose of this element in form to get Email from User.
Example in ASP.NET
<asp:DropDownList ID="DropDownListChapterTitle" runat="server" AutoPostBack="true" CssClass="CommonTextBoxStyle responsive_textbox" OnSelectedIndexChanged="DropDownListChapterTitle_SelectedIndexChanged" ValidationGroup="InsertChapter"> </asp:DropDownList>
The purpose of this element in form to select the Chapter Title from drop down list
Step 3. Write clear and descriptive labels
For each form element, write a clear and descriptive label that explains the purpose or expected input. The label should be concise but informative. Avoid using generic labels like "Field 1" or "Textbox 2."
Example in HTML
<label for="txtemail" class="label" id="spantxtEmailAddress">Email<span class="MessageTextRed">*</span></label>
Example in ASP.NET
<asp:Label runat="server" AssociatedControlID="DropDownListChapterTitle" Text="Chapter Title :"></asp:Label>
Step 4. Associate the labels with the form elements
Once you have written the labels, you need to associate them with the corresponding form elements. This can be done using the HTML "for" attribute and the "id" attribute in your web page.
Example in HTML
<label for="txtemail" class="label" id="spantxtEmailAddress">Email<span class="MessageTextRed">*</span></label>
<input type="text" onkeyup="success()" maxlength="50" runat="server" tabindex="0" clientidmode="static" id="txtemail" name="useremail" class="input_text" onchange="return validateEmail(this);" data-message="Email can't be blank." />
Example in ASP.NET
<asp:Label runat="server" AssociatedControlID="DropDownListChapterTitle" Text=""></asp:Label>
<asp:DropDownList ID="DropDownListChapterTitle" runat="server" AutoPostBack="true" CssClass="CommonTextBoxStyle responsive_textbox" OnSelectedIndexChanged="DropDownListChapterTitle_SelectedIndexChanged" ValidationGroup="InsertChapter"> </asp:DropDownList>
Make sure that the "for" attribute value matches the "id" attribute value of the form element in your page.
Step 5. Test the form with screen readers or assistive technology
To ensure accessibility, test the form using screen readers or other assistive technologies. This will help you verify that the labels are properly associated with the form elements and are being read aloud correctly.
Example I have use LightHouse which is inbuild in Chrome Browser

Step 6. Check for visual alignment
After adding labels, check if the labels and form elements are visually aligned properly. This improves the overall appearance and makes it easier for users to associate the labels with the corresponding elements.
Step 7. Repeat for all form elements without labels
Go through each form element that lacks a label and repeat steps 3 to 6 until all elements have clear and associated labels in your HTML page or ASP.NET page.
Conclusion
Ensuring that form elements have associated labels is crucial for optimizing accessibility and usability. By following the step-by-step process outlined above, you can address the issue of form elements lacking labels effectively. Clear and descriptive labels help users understand the purpose and context of each form element, improving the overall user experience. Associating labels with form elements using the appropriate HTML attributes ensures proper functionality, particularly for screen readers and assistive technologies. By testing and visually aligning the labels and form elements, you can further enhance the accessibility and visual presentation of your forms. Prioritizing the inclusion of associated labels in form design promotes inclusivity and facilitates seamless interaction for all users.
