Send that on over and I can give you some advice. Currently, your existing code looks functional to me.

My problem is that I cannot get it to pass the id="targetTag" from the input line of code through the onclick and to the Javascript function as a variable to use in function. My code is as follows - any help would be appreciated. getElementsByTagName example function changeCSS(tagID) { var currentTag = document.getElementById(tagID); currentTag.setAttribute("class", "secondClass"); currentTag.setAttribute("className", "secondClass"); return; } .firstClass { background-color: #F99; } .secondClass { background-color: #F00; } Adjust link CSS Thanks for publishing this piece of code – it is just what I am looking for however I cannot get it to work. My problem is that I cannot get it to pass the id=”targetTag” from the input line of code through the onclick and to the Javascript function as a variable to use in function.

getElementsByTagName example

function changeCSS(tagID)
{
var currentTag = document.getElementById(tagID);
currentTag.setAttribute(“class”, “secondClass”);
currentTag.setAttribute(“className”, “secondClass”);
return;
}

.firstClass {
background-color: #F99;
}
.secondClass {
background-color: #F00;
}

Adjust link CSS
