Realizing that form input placeholders aren't universally recognized among browsers, I began changing all of mine using onblur and onfocus handlers instead. As an example, I used the following code, which works in most cases:

<input type="text" name="example" maxlength="5" value="Example" onblur="if(this.value=='') this.value='Example';" onfocus="if(this.value=='Example') this.value='';"/>
At first, I coded all of the inputs without a value attribute. But, when the page initially loaded, the fields would load empty, and the value/placeholder wouldn't appear until the field had been "focused" and then "blurred" again. Adding the value attribute seemed to correct that problem, again, for the most part.

I have some text fields that appear only after I select a particular radio button or select option. Problem is, when the radio is clicked, the field appears, but even with the value attribute in place, the field appears void. I'm not sure what is different, or what I'm doing wrong. Here's the javascript code with the radio button (note:everything works except that the "placeholder" doesn't show when the field first appears):

function showfield() {
    document.forms[0].otherRelation.value = "";
    document.getElementById("newBox").style.display = "none";

    var r = document.forms[0].relation;
    var len = r.length;
    for (var i =0; i<len; i++) {
        if (r[i].checked && r[i].value == "Otherrelation" ) {
            document.getElementById("newBox").style.display = "inline";

<input type="radio" name="relation" value="Otherrelation" onclick="showfield()"/>Other
	<span id = "newBox" style="display:none">: 
		<input type = "text" name="otherRelation" size="35" value="Your Relationship" onblur="if(this.value=='') this.value='Your Relationship';" onfocus="if(this.value=='Your Relationship') this.value='';"/>
Thanks for any help. Sorry so long.
