I am making a simple form and i have this code to clear the initial value:
Javascript:
function clearField(input) {
input.value = "";
};
html:
<input name="name" id="name" type="text" value="Name" onfocus="clearField(this);"/>
But what i don't want is that if the user fills the input but clicks it again, it gets erased. I want the field to have the starter value "Name" only if the input is empty. Thank you in advance!
This question is related to
javascript
jquery
html
Here is one solution with jQuery for browsers that don't support the placeholder attribute.
$('[placeholder]').focus(function() {
var input = $(this);
if (input.val() == input.attr('placeholder')) {
input.val('');
input.removeClass('placeholder');
}
}).blur(function() {
var input = $(this);
if (input.val() == '' || input.val() == input.attr('placeholder')) {
input.addClass('placeholder');
input.val(input.attr('placeholder'));
}
}).blur();

HTML:
<input name="name" id="name" type="text" value="Name" onfocus="clearField(this);" onblur="fillField(this);"/>
JS:
function clearField(input) {
if(input.value=="Name") { //Only clear if value is "Name"
input.value = "";
}
}
function fillField(input) {
if(input.value=="") {
input.value = "Name";
}
}
This may be what you want:
This code places a default text string Enter your name here
inside the <input>
textbox, and colorizes the text to light grey.
As soon as the box is clicked, the default text is cleared and text color set to black.
If text is erased, the default text string is replaced and light grey color reset.
HTML:
<input id="fname" type="text" />
jQuery/javascript:
$(document).ready(function() {
var curval;
var fn = $('#fname');
fn.val('Enter your name here').css({"color":"lightgrey"});
fn.focus(function() {
//Upon ENTERING the field
curval = $(this).val();
if (curval == 'Enter your name here' || curval == '') {
$(this).val('');
$(this).css({"color":"black"});
}
}); //END focus()
fn.blur(function() {
//Upon LEAVING the field
curval = $(this).val();
if (curval != 'Enter your name here' && curval != '') {
$(this).css({"color":"black"});
}else{
fn.val('Enter your name here').css({"color":"lightgrey"});
}
}); //END blur()
}); //END document.ready
var input= $(this);
input.innerHTML = '';
do like
<input name="name" id="name" type="text" value="Name"
onblur="fillField(this,'Name');" onfocus="clearField(this,'Name');"/>
and js
function fillField(input,val) {
if(input.value == "")
input.value=val;
};
function clearField(input,val) {
if(input.value == val)
input.value="";
};
