htmlElement.SetAttribute

Hi Experts,

Below you will find my html test page and the vb.Net code I am using to try to turn both the <a> tag backgrounds green. Why does it not work?

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>H Test</title>
</head>
<body>
<div >
<a style="background-color:Red;" href="http://www.google.com">Google</a></div>
<br />
<div>
<a href="http://www.yahoo.com">Yahoo</a></div>
</body>
</html>

Dim elementCollection As HtmlElementCollection

elementCollection = WebBrowser1.Document.GetElementsByTagName("a")

For Each element As HtmlElement In elementCollection

element.SetAttribute("style", "background-color:green;")

Have you stepped through the code to see if it is running through the for loop?

Does changing green to Green help?

The code is running the loop and Green makes no difference.

Does the browser need to be refreshed after the attributes are changed or does the SetAttribute do that automatically?

Nasir Razzaq

It should do it automatically. Experiment by adding a button which does the same thing in Javascript and see if that works.

The following javascript works.

function TurnGreen() {

var elementsCol = document.getElementsByTagName("a")

for (var index = 0; index < elementsCol.length; index++) {
document.getElementsByTagName("a")[index].setAttribute("style", "background-color:Green");
}

}

Accessing the elements style property like this works

element.Style = "background-color: green"

This for some reason does not.

element.SetAttribute("style", "background-color:green;")
