Question

I am trying to pass a value on the server side to the onclick handler of a tag, but it is giving different result on the client side when I click on the link.

My PHP code:

$any="link1";
echo(" <a id='link1' href='#' onclick='VisibleFalse($any)'>[+]</a><span><b>$candidatename</b></span>");

I want to pass the string "link1" to the function VisibleFalse, which is showing the string as an alert:

function VisibleFalse(ID)
{
    alert(ID);
}

But it is printing "http://localhost/..." in the alert.

I would appreciate any of your suggestions.

Problem is, you’re passing a string and you forgot to add quotes to it so that the end result would be a string inside that JavaScript function. Here’s a better way to look at this:

$any="link1";
// First, echo isn't a function. It can be faked to be used as one, but that's not recommended
// Second, sort out your quoting like this:
echo '<a id="link1" href="#" onclick="VisibleFalse(\''.$any.'\')">[+]</a><span><b>'.$candidatename.'</b></span>';

// OR
echo "<a id='link1' href='#' onclick='VisibleFalse(\"$any\")'>[+]</a><span><b>$candidatename</b></span>";
