We will be needing a js file and a page containing form input field to do this task.
What we are planning is, The input field contains default value. Onclick default value disappears and allows the user to insert text.
If the user types anything it remains there but if he does not write anything and clicks at next input field than the default value reappears in previous field.
JS file Code:
function remName(a, b){
if(a.value==b){
a.value='';
}else if(a.value==''){
a.value=b;
}else{
a.value=a.value;
}
}
function chkName(a, b){
if(a.value==''){
a.value=b;
}else{
a.value=a.value;
}
}
Two functions are controlling the event as above.
Call the js file in the page and define input fields and put some code like this.
Input Fields:
<input name="txtName" type="text" id="txtName" onfocus="remName(this, 'Name');" onblur="chkName(this, 'Name');" value="Name">
<input name="txtEmail" type="text" id="txtEmail" value="Email" onfocus="remName(this, 'Email');" onblur="chkName(this, 'Email');">
and so on…

<fieldset>
<legend>
Health information:
</legend>
<form action=”">
Height <input type=”text” size=”3″>
Weight <input type=”text” size=”3″>

If there is no border around the input form, your browser is too old.

<body onLoad=”frm.name.focus();”>
Onload, form field name will be focused. name is the first field value. frm is the form name here.
This is helpful when you want to give user facility to autoselect the field in form instead of go and click in the field to start typing in the form.

}
function highlight(e){
eventobj=ns6? e.target : event.srcElement
if (previous!=”){
if (checkel(previous))
previous.style.backgroundColor=”
previous=eventobj
if (checkel(eventobj))
eventobj.style.backgroundColor=highlightcolor
}
else{
if (checkel(eventobj))
eventobj.style.backgroundColor=highlightcolor
