我如何检查是否在jQuery 中隐藏了元素 ?

如何使元素的可见度.hide(), .show(),或.toggle()?

如果一个元素是visible或hidden?

当前回答

使用任何可见的选择器或隐藏的选择器检查粘度 :

使用.toggle ()- 显示和隐藏元素

function checkVisibility() {
    // check if element is hidden or not and return true false
    console.log($('#element').is(':hidden'));

    // check if element is visible or not and return true false
    console.log($('#element').is(':visible'));

    if ( $('#element').css('display') == 'none' || $('#element').css("visibility") == "hidden"){
        console.log('element is hidden');
    } else {
        console.log('element is visibile');
    }
}

checkVisibility()
$('#toggle').click(function() {
    $('#element').toggle()
    checkVisibility()
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button id='toggle'>Toggle</button>
<div style='display:none' id='element'>
    <h1>Hello</h1>
    <p>it's visible</p>
</div>

$(document).ready(function() {
  if ($("#checkme:hidden").length) {
    console.log('Hidden');
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="checkme" class="product" style="display:none">
  <span class="itemlist"><!-- Shows Results for Fish --></span> Category:Fish
  <br>Product: Salmon Atlantic
  <br>Specie: Salmo salar
  <br>Form: Steaks
</div>

if($('#postcode_div').is(':visible')) {
    if($('#postcode_text').val()=='') {
        $('#spanPost').text('\u00a0');
    } else {
        $('#spanPost').text($('#postcode_text').val());
}

因为Elements with visibility: hidden or opacity: 0 are considered visible, since they still consume space in the layout(截至2004年12月1日jj 查询: 可见选择器- 我们可以检查元素是否真的以这种方式可见:

function isElementReallyHidden (el) {
    return $(el).is(":hidden") || $(el).css("visibility") == "hidden" || $(el).css('opacity') == 0;
}

var booElementReallyShowed = !isElementReallyHidden(someEl);
$(someEl).parents().each(function () {
    if (isElementReallyHidden(this)) {
        booElementReallyShowed = false;
    }
});

ebdiv定定定style="display:none;"它既用于显示也用于隐藏:

$(document).ready(function(){
    $("#eb").click(function(){
        $("#ebdiv").toggle();
    });    
});
