In this article I will explain with an example, how to display Text when CheckBox is checked (selected) or unchecked (unselected) using JavaScript and jQuery.
When the CheckBox is clicked based on whether it is checked (selected) or unchecked (unselected), the HTML DIV with some Text will be shown or hidden.
Display Text when CheckBox is checked or unchecked using JavaScript
The HTML Markup consists of a CheckBox and an HTML DIV consisting of a TextBox. The CheckBox has been assigned a JavaScript OnClick event handler.
When the CheckBox is clicked, the ShowHideDiv JavaScript function is executed. Inside this function, based on whether CheckBox is checked (selected) or unchecked (unselected), the HTML DIV with TextBox is shown or hidden.
<script type="text/javascript">
function ShowHideDiv(chkPassport) {
var dvPassport = document.getElementById("dvPassport");
dvPassport.style.display = chkPassport.checked ? "block" : "none";
}
</script>
<label for="chkPassport">
<input type="checkbox" id="chkPassport" onclick="ShowHideDiv(this)" />
Do you have Passport?
</label>
<hr />
<div id="dvPassport" style="display: none">
Passport Number:
<input type="text" id="txtPassportNumber" />
</div>
Display Text when CheckBox is checked or unchecked using jQuery
The HTML Markup consists of a CheckBox and an HTML DIV consisting of a TextBox. The CheckBox has been assigned a jQuery OnClick event handler.
When the CheckBox is clicked, based on whether CheckBox is checked (selected) or unchecked (unselected), the HTML DIV with TextBox is shown or hidden.
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
$(function () {
$("#chkPassport").click(function () {
if ($(this).is(":checked")) {
$("#dvPassport").show();
} else {
$("#dvPassport").hide();
}
});
});
</script>
<label for="chkPassport">
<input type="checkbox" id="chkPassport" />
Do you have Passport?
</label>
<hr />
<div id="dvPassport" style="display: none">
Passport Number:
<input type="text" id="txtPassportNumber" />
</div>
