javascript - How to check whether a checkbox is checked in jQuery? -


i need check checked property of checkbox , perform action based on checked property using jquery.

for example, if age checkbox checked, need show textbox enter age, else hide textbox.

but following code returns false default:

if($('#isageselected').attr('checked')) {     $("#txtage").show(); } else {     $("#txtage").hide(); }

how query checked property?

how query checked property?

the checked property of checkbox dom element give checked state of element.

given existing code, therefore this:

if(document.getelementbyid('isageselected').checked) {     $("#txtage").show(); } else {     $("#txtage").hide(); }

however, there's prettier way this, using toggle:

$('#isageselected').click(function() {      $("#txtage").toggle(this.checked);  });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <input type="checkbox" id="isageselected"/>  <div id="txtage" style="display:none">age something</div>

(int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
