SUMMARY

Use this step-by-step guide to add wildcard characters to a database search form by using Dynamic HTML (DHTML). The example in this article uses a Like query and DHTML to create a better verion of the built-in Contains query.

NOTE: This article uses custom DHTML that may not be available in all browsers. For more information about compatibility with other browsers, click Microsoft FrontPage Help on the Help menu, type compatibility in the Office Assistant or the Answer Wizard, and then click Search to view the topic.

NOTE: You may receive an error message if you copy the examples directly from this article and paste them into FrontPage. The angle brackets (< and >) may appear as escaped HTML code (< and >). To work around this behavior, paste the script into a blank Notepad document, and then copy it from Notepad before you paste it into FrontPage.

Step 3 - Add DHTML to the Page

1. Switch to HTML view.

2. Add the following DHTML code before the closing </HEAD> tag:

   <script language="javascript">
   function FixMe(tmpForm,tmpField)
   {
     var strTemp = tmpField.value.toString();
     if (strTemp.substring(0,1) != '%')
       strTemp = '%' + strTemp;
     if (strTemp.substring(strTemp.length-1,strTemp.length) != '%')
       strTemp = strTemp + '%';
     tmpField.value = strTemp;
     tmpForm.submit();
   }
   </script>
                       

3. Locate and delete the following code:

   <form BOTID="0" METHOD="POST" ACTION="productname.asp">
                           

   and replace it with this code:

   <form BOTID="0" METHOD="POST" ACTION="productname.asp" onSubmit="FixMe(this,this.ProductName)">
                       

4. Switch back to normal view.
5. Save the page to your Web.

Step 4 - Test the Page

1. Click the Preview in Browser button on the Standard toolbar.
   

No form fields should appear on the page.

1. Do not type any text. Click Submit.
   

The search form field should contain a single percent sign (%) and all records are returned.
