function uncheck() {. var notTest = document.getElementById("choice_31_3_2"); var Test = document.getElementById("choice_31_3_1"); if (notTest.checked) {. Test.checked = false; } if (Test.checked) {. notTest.checked = false; }
you could use class for all your checkboxes, and do: $(".check_class").click(function() { $(".check_class").attr("checked", false); //uncheck all checkboxes $(this).attr("checked", true); //check the clicked one });
Asked 8 years, 3 months ago. Modified 8 years, 3 months ago. Viewed 2k times. 3. My purpose. When I click Check All in the first column, all check boxes in that column should be checked and the Set button should show up. While the other check boxes in other column should be unchecked.
Jquery $(".select-all").on("click", function() { $(".item-checkbox").prop("checked", $(this).prop("checked")); }); OR (if you can't assign a class for some reason) $("input[name=selectAll]").on("click", function() { $("input:checkbox").prop("checked", $(this).prop("checked")); });
To uncheck all checkboxes in your form, you can use the :checkbox selector along with the .prop() method. Here's how: $("input:checkbox").prop('checked', false); If you want to uncheck a checkbox after a certain event (like a button click), you can use jQuery event methods like .click() or .on().
You can use the jQuery prop() method to check or uncheck a checkbox dynamically such as on click of button or an hyperlink etc. The prop() method require jQuery 1.6 and above. Let's try out the following example to understand how it basically works: Example. Try this code ยป <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8">
Use the prop() Method to Check and Uncheck a Checkbox in jQuery. Use the attr() Method to Check and Uncheck a Checkbox in jQuery. There are two ways to check and uncheck a checkbox. For the versions of jQuery above 1.6, the prop() function is used, and for versions below 1.6, the attr() function is used.
For checking and unchecking a checkbox, you can either use JavaScript or jQuery methods described below. Watch a video course JavaScript -The Complete Guide (Beginner + Advanced) JavaScript. Use the following code to check and uncheck checkbox using JavaScript:
$('input:checkbox.class1').live('change', function { var n = $(this).parents('.elements').first().find('input:checkbox.class2'); if ($(this).attr('checked')) { n.attr('checked',true); n.attr('disabled', true); } else { n.attr('disabled',false); } });
1. Checking if a checkbox is checked by using is. This is actually the way I would recommend for anyone using jQuery: if( $ ('#el').is (':checked') ) { alert ("Checkbox Is checked"); } else{ alert ("Checkbox Is not checked"); } Code language:JavaScript(javascript) So how does it work?
