我的水平滚动站点周围有这些菜单。
<section class="fun-stuff portfolio-cards" id="slide-1">
<div class="nav-list">
<button class="about">ABOUT</button>
<button class="fun-stuff">FUN STUFF</button>
<button class="home">HOME</button>
<button class="professional">PROFESSIONAL</button>
<button class="contact">CONTACT</button>
</div>
</section
目的是根据按钮类是否与本节中的类相同,对它们进行过滤。如果它们具有相同的类(在此示例中为“ fun-stuff”),则该按钮将显示:无。
我的jQuery。我觉得我已经接近或完全复杂化了。
jQuery(document).ready(function($) {
var theList = $('.nav-list button');
var i;
for (i=0; i < theList.length; i++){
var theButtons = '"' + theList[i].className + '"';
var parentClassName = theList[i].closest('section').className;
// tried this one. Was close i believe but no dice
if(theButtons = theList[i].closest('section').hasClass('"' + theButtons + '"') ){
// display that button as none
}
// tried this as well and for each button got 'no' in the console
if( $(theList[i].closest('section') ).hasClass(theButtons) ){
console.log('yes');
} else {
console.log ('no');
}
}
});
是的,你有些过分了
$(function() {
$("button").each(function() {
var $parent = $(this).closest("section"), // the section wrapping the button
same = $parent.hasClass($(this).attr("class")); // parent has this button's class too
$(this).toggle(!same); // hide if the same (show if not)
});
});

<section class="fun-stuff portfolio-cards" id="slide-1">
<div class="nav-list">
<button class="about">ABOUT</button>
<button class="fun-stuff">FUN STUFF</button>
<button class="home">HOME</button>
<button class="professional">PROFESSIONAL</button>
<button class="contact">CONTACT</button>
</div>
</section>
如果按钮上有多个班级,并且如果其中一个匹配,则要隐藏
$(function() {
$("button").each(function() {
var bList = this.classList,
parentList = $(this).closest("section")[0].classList, // the DOM element's classList
same = [...parentList] // convert to iterable
.filter(ele => bList.contains(ele)) // look up parent class in button classList
.length>0; // found?
$(this).toggle(!same);
});
});
