I have an input text that and a hide div.
I want to show the div when the input text has a value.
Here is the demo: http://jsfiddle.net/vyc7N/181/
<label for="db">Type whatever</label>
<input type="text"name="amount" />
<div id="yeah" style="display:none;">
<input type="submit" />
</div>
Please somebody can help me?
You can write the code in keyup event of textbox to get the length of text entered in it.
$('input[name=amount]').keyup(function(){
if($(this).val().length)
$('#yeah').show();
else
$('#yeah').hide();
});
you can also use .toggle()
instead of using .show
/ .hide()
:
$('input[name=amount]').keyup(function(){
$('#yeah').toggle($(this).val().length);
});
$('input[name=amount]').bind('keyup change', function(){
if(!$(this).val())
$("#yeah").css('display', 'none');
else
$("#yeah").css('display', '');
});
You could use onkeyup()
:
<label>Type whatever</label>
<input id='inptOne' type="text" name="amount" onkeyup="myFunction()" />
<div id="yeah" style="display:none">
<input type="submit" />
</div>
<script>
//if input has some value will show the button
window.myFunction = function() {
//alert('it ran!');
var hasValue = document.getElementById('inptOne').value;
if (!!hasValue) {
document.getElementById('yeah').style.display = 'inline';
} else {
document.getElementById('yeah').style.display = 'none';
};
};
</script>
Working fiddle
Use following logic : If after trimming there is some value , then show else hide.
$('input[name=amount]').keyup(function(){
if($.trim($(this).val())!='')
$('#yeah').show();
else
$('#yeah').hide();
});
