这是我的HTML:
<select id="ddlProducts" name="ddProducts">
<option>Product1 : Electronics </option>
<option>Product2 : Sports </option>
</select>
我想让产品的名称(即。'Product1', 'Product2',等等),以及它的类别(即。电子,体育等)斜体,只使用CSS。我发现了一个老问题,提到这是不可能使用HTML和CSS,但希望,现在有一个解决方案。
(() => {
const optionValues = document.querySelectorAll(".search-form__value");
const searchOptions = document.querySelector(".search-form__selector");
const dropdown = document.querySelector(".search-form__dropdown");
const input = document.getElementById("search-form-loc");
const selectorText = document.querySelector(".search-form__label--loc");
searchOptions.addEventListener("click", function () {
dropdownHandler();
});
optionValues.forEach((option) => {
option.addEventListener("click", function () {
updateUI(input, selectorText, this);
});
});
window.addEventListener("mouseup", function (event) {
if (event.target != dropdown) {
dropdown.classList.remove("search-form__dropdown--show");
}
});
function dropdownHandler() {
dropdown.classList.toggle("search-form__dropdown--show");
}
function updateUI(input, selectorText, referedThis) {
input.value = referedThis.textContent.trim();
selectorText.textContent = referedThis.textContent.trim();
dropdown.classList.remove("search-form__dropdown--show");
}
})();
