If you want to get true/false depending on whether the checkbox is checked, then I recommend using the following syntax: $(“#testCheckbox”).is(“:checked”);
:checked Selector
The :checked selector works for checkboxes, radio buttons, and options of select elements.
.is() Filtering
Check the current matched set of elements against a selector, element, or jQuery object and return true if at least one of these elements matches the given arguments.
Set True/False depends on the checkbox – jQuery Example
Here is a simple example. On the page we have a label, checkbox, and span. By clicking on the checkbox we need to set ‘true’ or ‘false’ into the span tag.
The full HTML and jquery code:
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
$(document).ready(function(){
$("#testCheckbox").click(function(){
var isChecked = $("#testCheckbox").is(":checked");
$("#checkBoxState").text(isChecked);
});
});
</script>
</head>
<body>
<h1>Get Checkbox Value</h1>
<label for="testCheckBox">Test CheckBox</label>
<input id="testCheckbox" name="testCheckBox" type="checkbox" />
<span id="checkBoxState"></span>
</body>
</html>
