jQuery UI को Customize करना

jQuery UI widgets options accept करते हैं। Options आपको library बदले बिना behavior बदलने देते हैं।

$("selector").widgetName({
  option: value,
  anotherOption: value
});

Widget Options Customize करना

ज़्यादातर jQuery UI widgets initialization पर एक configuration object accept करते हैं जो आपको उनके default behavior और appearance को override करने देता है — उदाहरण के लिए, set।

<body>
  <button id="runBtn">Run</button>
  <button id="resetBtn">Reset</button>
  <section id="demo">
    <input id="date">

  </section>
  <div id="output"></div>
  <script>
    var original = $("#demo").html();
    var $initial = $("body").children();

    $("#runBtn").click(function() {
      $("#date").datepicker({minDate: 0});
    });

    $("#resetBtn").click(function() {
      $("body").children().not($initial).remove();
      $("#demo").html(original);
      $("#output").empty();
    });
  </script>
</body>
</html>

Buttons Customize करना

button widget plain buttons और links को browsers पर एक consistent visual style देता है, और यह icons तथा disabled जैसी अलग visual states support करता है।

उदाहरण: Customize Buttons

javascript 
<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" href="https://code.jquery.com/ui/1.13.2/themes/base/jquery-ui.css">
  <script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
  <script src="https://code.jquery.com/ui/1.13.2/jquery-ui.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">
    <button id="btn">Save</button>

  </section>
  <div id="output"></div>
  <script>
    var original = $("#demo").html();

    $("#runBtn").click(function() {
      $("#btn").button({icon: "ui-icon-disk"});
    });

    $("#resetBtn").click(function() {
      $("#demo").html(original);
      $("#output").empty();
    });
  </script>
</body>
</html>

Dialogs Customize करना

Dialog options size, starting position, dialog page के बाकी हिस्से के साथ interaction block करता है या नहीं (modal), और खुलने पर क्या होता है control करते हैं।

उदाहरण: Customize Dialogs

javascript 
<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" href="https://code.jquery.com/ui/1.13.2/themes/base/jquery-ui.css">
  <script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
  <script src="https://code.jquery.com/ui/1.13.2/jquery-ui.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">
    <div id="dialog" title="Settings">Options</div>

  </section>
  <div id="output"></div>
  <script>
    var original = $("#demo").html();
    var $initial = $("body").children();

    $("#runBtn").click(function() {
      $("#dialog").dialog({modal: true, width: 400});
    });

    $("#resetBtn").click(function() {
      $("body").children().not($initial).remove();
      $("#demo").html(original);
      $("#output").empty();
    });
  </script>
</body>
</html>

Widgets Combine करना

एक ही page पर कई jQuery UI widgets साथ काम कर सकते हैं — उदाहरण के लिए, एक datepicker वाला एक resizable dialog — और कुछ widgets को combine करना।

उदाहरण: Combine Widgets

javascript 
<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" href="https://code.jquery.com/ui/1.13.2/themes/base/jquery-ui.css">
  <script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
  <script src="https://code.jquery.com/ui/1.13.2/jquery-ui.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">
    <div id="dialog" title="Pick a date">
      <input id="date">
    </div>

  </section>
  <div id="output"></div>
  <script>
    var original = $("#demo").html();
    var $initial = $("body").children();

    $("#runBtn").click(function() {
      $("#date").datepicker();
      $("#dialog").dialog({resizable: true});
    });

    $("#resetBtn").click(function() {
      $("body").children().not($initial).remove();
      $("#demo").html(original);
      $("#output").empty();
    });
  </script>
</body>
</html>

एक छोटा Custom UI Project

एक पूरी तरह customized jQuery UI page आमतौर पर कई widgets, draggable या sortable जैसी एक या ज़्यादा interactions, और एक पर consistent easing combine करता है।

उदाहरण: Small Custom UI Project

javascript 
<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" href="https://code.jquery.com/ui/1.13.2/themes/base/jquery-ui.css">
  <script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
  <script src="https://code.jquery.com/ui/1.13.2/jquery-ui.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">
    <div id="dialog" title="Schedule">
      <input id="date">
    </div>

  </section>
  <div id="output"></div>
  <script>
    var original = $("#demo").html();
    var $initial = $("body").children();

    $("#runBtn").click(function() {
      $("#date").datepicker();
      $("#dialog").dialog({modal: true});
    });

    $("#resetBtn").click(function() {
      $("body").children().not($initial).remove();
      $("#demo").html(original);
      $("#output").empty();
    });
  </script>
</body>
</html>

{# common_mistakes/chapter_summary/browser_support: on Hindi pages the view already swaps in the hi_ translation fields (or blanks these out if untranslated), so this renders correctly for both languages without a lang_code check here. #}
आम गलतियां
  1. initialization के बाद फिर .dialog({ width: 600 }) call करके options pass करना, जबकि इसे .dialog("option", "width", 600) से set किया जाना चाहिए।
  2. किसी dialog पर modal: true set करना और इसे बंद करने का कोई तरीका भूल जाना, जैसे buttons option, page को blocked छोड़ते हुए।
  3. elements पर .button() इस्तेमाल करना और jQuery UI CSS के बिना theme काम करने की उम्मीद करना, ताकि buttons plain दिखें।
चैप्टर सारांश
  • jQuery UI jQuery के ऊपर interaction helpers और widgets add करता है।
  • Essential widgets ready-made interface components देते हैं।
  • Custom transitions और easing, और customization, यह adjust करते हैं कि यह कैसा दिखता और चलता है।
