Is there a way to change my icon from expand_more to expand_less in the code below?
<li class="dropdown-bt" onclick="dropdown('content');">
<a>dropdown-content <i class="material-icons">expand_more</i></a>
</li>
I need to use this code multiple times and don't want to assign an ID to each one. Is there a way to write a single function to handle this change? Any help would be appreciated.
To access the content of an element, simply pass an object event named e as a parameter to the function dropdown(). Then, utilize the textContent property to fetch the current element content. You can then compare the value and update it with a different text content as shown in the code snippet below:
var button = document.getElementById("dropdownButton");
function dropdown(e) {
var text = e.target.children[0];
if(text.textContent == "show more") {
text.textContent = "show less";
} else {
text.textContent = "show more";
}
}
button.addEventListener('click', dropdown);<button id="dropdownButton">Dropdown Button <span>show more</span></button>Apologies for the unconventional terminology in the query, but I am struggling to find better words to describe it. Hopefully, this example will clarify my intention: scss-syntax .my-smug-selector { @include my-smug-mixin(30px); } desired css-output ...
