Form Selectors
In this page:
$(":input")
$(":text")
$(":checkbox")
$(":radio")
$(":submit")
Input Selector
':input' matches every form control on the page, including textareas, selects, and buttons, not just <input> tags. It's the broadest of jQuery's form-related selectors.
Example: Input Selector
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
<style>
button { padding:6px 14px; margin:4px; background:#2c6aa0; color:white; border:none; border-radius:4px; cursor:pointer; }
#resetBtn { background:white; color:#2c6aa0; border:1px solid #2c6aa0; }
#output { margin-top:10px; padding:8px; border:1px solid #ccc; border-radius:4px; background:#f7f7f7; font-family:monospace; min-height:24px; }
.btn { display:inline-block; padding:6px 14px; margin:4px; background:#2c6aa0; color:white; border-radius:4px; cursor:pointer; font:13px sans-serif; }
#resetBtn.btn { background:white; color:#2c6aa0; border:1px solid #2c6aa0; }
#demo :where(p, div, span, li, h1, h2, h3, h4, td, th, blockquote, label, section, article, aside) { border:1px solid #4a7fb5; background:#eaf2fb; padding:6px 10px; margin:4px 0; border-radius:4px; }
#demo :where(ul, ol) { border:1px dashed #888; background:#fafafa; padding:8px 8px 8px 32px; margin:6px 0; }
#demo :where(table) { border-collapse:collapse; }
#demo :where(td, th) { border-radius:0; }
#demo :where(input, select, textarea) { margin:4px 0; }
</style>
</head>
<body>
<span id="runBtn" class="btn" role="button">Run</span>
<span id="resetBtn" class="btn" role="button">Reset</span>
<section id="demo">
<input><textarea></textarea><button>Go</button>
</section>
<div id="output"></div>
<script>
var original = $("#demo").html();
$("#runBtn").click(function() {
$("#output").text($(":input").length);
});
$("#resetBtn").click(function() {
$("#demo").html(original);
$("#output").empty();
});
</script>
</body>
</html>
Text Input Selector
The ':text' selector narrows that down to just single-line text inputs, ignoring every other control type like checkboxes or buttons. It's shorthand for input[type="text"] but slightly slower since it can't use a native browser lookup.
Example: Text Input Selector
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
<style>
button { padding:6px 14px; margin:4px; background:#2c6aa0; color:white; border:none; border-radius:4px; cursor:pointer; }
#resetBtn { background:white; color:#2c6aa0; border:1px solid #2c6aa0; }
#output { margin-top:10px; padding:8px; border:1px solid #ccc; border-radius:4px; background:#f7f7f7; font-family:monospace; min-height:24px; }
#demo :where(p, div, span, li, h1, h2, h3, h4, td, th, blockquote, label, section, article, aside) { border:1px solid #4a7fb5; background:#eaf2fb; padding:6px 10px; margin:4px 0; border-radius:4px; }
#demo :where(ul, ol) { border:1px dashed #888; background:#fafafa; padding:8px 8px 8px 32px; margin:6px 0; }
#demo :where(table) { border-collapse:collapse; }
#demo :where(td, th) { border-radius:0; }
#demo :where(input, select, textarea) { margin:4px 0; }
</style>
</head>
<body>
<button id="runBtn">Run</button>
<button id="resetBtn">Reset</button>
<section id="demo">
<input type="text"><input type="checkbox">
</section>
<div id="output"></div>
<script>
var original = $("#demo").html();
$("#runBtn").click(function() {
$("#output").text($(":text").length);
});
$("#resetBtn").click(function() {
$("#demo").html(original);
$("#output").empty();
});
</script>
</body>
</html>
Password Selector
The ':password' selector targets only password fields, which is useful when you need to validate or mask that specific input differently from regular text fields.
Example: Password Selector
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
<style>
button { padding:6px 14px; margin:4px; background:#2c6aa0; color:white; border:none; border-radius:4px; cursor:pointer; }
#resetBtn { background:white; color:#2c6aa0; border:1px solid #2c6aa0; }
#output { margin-top:10px; padding:8px; border:1px solid #ccc; border-radius:4px; background:#f7f7f7; font-family:monospace; min-height:24px; }
#demo :where(p, div, span, li, h1, h2, h3, h4, td, th, blockquote, label, section, article, aside) { border:1px solid #4a7fb5; background:#eaf2fb; padding:6px 10px; margin:4px 0; border-radius:4px; }
#demo :where(ul, ol) { border:1px dashed #888; background:#fafafa; padding:8px 8px 8px 32px; margin:6px 0; }
#demo :where(table) { border-collapse:collapse; }
#demo :where(td, th) { border-radius:0; }
#demo :where(input, select, textarea) { margin:4px 0; }
</style>
</head>
<body>
<button id="runBtn">Run</button>
<button id="resetBtn">Reset</button>
<section id="demo">
<input type="password"><input type="text">
</section>
<div id="output"></div>
<script>
var original = $("#demo").html();
$("#runBtn").click(function() {
$("#output").text($(":password").length);
});
$("#resetBtn").click(function() {
$("#demo").html(original);
$("#output").empty();
});
</script>
</body>
</html>
Checkbox and Radio
':checkbox' and ':radio' let you select those specific control types directly, which is often paired with .prop(checked) to read or set whether they're currently selected.
Example: Checkbox and Radio
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
<style>
button { padding:6px 14px; margin:4px; background:#2c6aa0; color:white; border:none; border-radius:4px; cursor:pointer; }
#resetBtn { background:white; color:#2c6aa0; border:1px solid #2c6aa0; }
#output { margin-top:10px; padding:8px; border:1px solid #ccc; border-radius:4px; background:#f7f7f7; font-family:monospace; min-height:24px; }
#demo :where(p, div, span, li, h1, h2, h3, h4, td, th, blockquote, label, section, article, aside) { border:1px solid #4a7fb5; background:#eaf2fb; padding:6px 10px; margin:4px 0; border-radius:4px; }
#demo :where(ul, ol) { border:1px dashed #888; background:#fafafa; padding:8px 8px 8px 32px; margin:6px 0; }
#demo :where(table) { border-collapse:collapse; }
#demo :where(td, th) { border-radius:0; }
#demo :where(input, select, textarea) { margin:4px 0; }
</style>
</head>
<body>
<button id="runBtn">Run</button>
<button id="resetBtn">Reset</button>
<section id="demo">
<input type="checkbox" checked><input type="radio">
</section>
<div id="output"></div>
<script>
var original = $("#demo").html();
$("#runBtn").click(function() {
$("#output").text(String($(":checkbox").prop("checked")));
});
$("#resetBtn").click(function() {
$("#demo").html(original);
$("#output").empty();
});
</script>
</body>
</html>
Submit and File
jQuery also provides ':submit' for submit buttons and ':file' for file-upload inputs, rounding out the full set of form-control selectors you can target individually.
Example: Submit and File
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
<style>
button { padding:6px 14px; margin:4px; background:#2c6aa0; color:white; border:none; border-radius:4px; cursor:pointer; }
#resetBtn { background:white; color:#2c6aa0; border:1px solid #2c6aa0; }
#output { margin-top:10px; padding:8px; border:1px solid #ccc; border-radius:4px; background:#f7f7f7; font-family:monospace; min-height:24px; }
.btn { display:inline-block; padding:6px 14px; margin:4px; background:#2c6aa0; color:white; border-radius:4px; cursor:pointer; font:13px sans-serif; }
#resetBtn.btn { background:white; color:#2c6aa0; border:1px solid #2c6aa0; }
#demo :where(p, div, span, li, h1, h2, h3, h4, td, th, blockquote, label, section, article, aside) { border:1px solid #4a7fb5; background:#eaf2fb; padding:6px 10px; margin:4px 0; border-radius:4px; }
#demo :where(ul, ol) { border:1px dashed #888; background:#fafafa; padding:8px 8px 8px 32px; margin:6px 0; }
#demo :where(table) { border-collapse:collapse; }
#demo :where(td, th) { border-radius:0; }
#demo :where(input, select, textarea) { margin:4px 0; }
</style>
</head>
<body>
<span id="runBtn" class="btn" role="button">Run</span>
<span id="resetBtn" class="btn" role="button">Reset</span>
<section id="demo">
<input type="submit"><input type="file">
</section>
<div id="output"></div>
<script>
var original = $("#demo").html();
$("#runBtn").click(function() {
$("#output").text($(":submit").length + " " + $(":file").length);
});
$("#resetBtn").click(function() {
$("#demo").html(original);
$("#output").empty();
});
</script>
</body>
</html>
- Assuming
:inputmatches only<input>tags; it also matches<textarea>,<select>and<button>. - Using
:textand expecting it to find a<textarea>or an input with notypeattribute reliably, when it targetsinput[type=text]only. - Writing
$(":checkbox")and expecting only checked boxes; it selects every checkbox, and you need:checkedto narrow it down.
