finding certain text in html page+vbsript

sharjeel · #1 (**permalink**) 05-15-2007, 05:15 AM

I am new to vbscript.I have basic knowledge of vbscripting. Now I have to implement a code in vbscript which will get input (search string) form the user on a webpage and highlight the matching string on this page. Can anyone provide me any sample code or hint in this regard.

Thanks in advance.

Best regards,

Here is a simple VBScript that should do what you are saying, but to keep some problems from occuring the searchable text must be in a <SPAN> with the class name of "searchMe" (ie: <span class="searchMe">searchable text</span>)

anyway try playing around with it:

HTML Code:

<html>
<head>
<script type="text/vbscript">
OrigBody = ""
Function findAndHighlight(strFind)
    If OrigBody = "" Then
        OrigBody = document.body.innerHTML
    End If
    Set myRegExp = New RegExp
    myRegExp.Global = True
    myRegExp.Pattern = "(" + strFind + ")"
    'Uncomment this to search with case sensative'
    myRegExp.IgnoreCase = True
    For Each mySpan In document.getElementsByTagName("span")
    If mySpan.className = "searchMe" Then
        mySpan.innerHTML = myRegExp.Replace(mySpan.innerHTML, "<span style=" + """" + "background-color:yellow" + """" + ">$1</span>")
        End If
    Next
End Function
Function resetBody()
    document.body.innerHTML = OrigBody
    OrigBody = ""
End Function
</script>
</head>
<body>
<span class="searchMe">Here is some text, that is used to test code.</span><br />
<input type="text" name="lookFor" id="lookFor" />
<input type="button" onclick="findAndHighlight(document.getElementById('lookFor').value)" value="Search" />
<input type="button" onclick="resetBody()" value="Reset" />
</body>
</html>

Btw... the reason the color coding is all funny looking is because it is color coded for javascript
