html - How to hide elements with jQuery before they get rendered?

asked Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

I want to generate html layout with areas (divs, spans) that can be shown/hidden conditionally. These areas are hidden by default.

If I call .hide() method with jquery on document.ready these areas may blink (browsers render partially loaded documents). So I apply "display: none" style in html layout.

I wonder what is the best practice to avoid blinking, because applying "display:none" breaks incapsulation rule - I know what jquery does with hide/show and use it. If jquery's hiding/showing implementation will change one day, I'll get the whole site unworkable.

Thank you in advance

@Andrew,

I know the answer has already been accepted, but using display: none; will be a nightmare to users without Javascript.

Using inline Javascript, you can hide an element without it ever blinking. Users without Javascript will still be able to see it.

Consider a few divs that should be hidden when the page loads.

<head>
    <script type="text/javascript" src="jQuery.js"></script>
</head>
<body>
    <div id="hide-me">
        ... some content ...
    </div>
    <script type="text/javascript">
        $("#hide-me").hide();
    </script>

    <div id="hide-me-too">
        ... some content ...
    </div>
    <script type="text/javascript">
        $("#hide-me-too").hide();
    </script>
</body>

The inline Javascript will run as soon as the element is rendered, thus hiding it from the user.
