篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了如何根据第二列的内容调整下拉列表中每一行的高度?相关的知识,希望对你有一定的参考价值。
我使用selectMenu jQuery小部件创建了一个下拉列表,然后在Angular中使用它创建了一个下拉组件,这样我就可以重用相同的组件。现在,我面临的问题是下拉列表由3列组成,第2列包含每行的主要内容。现在,每当我增加要放入第二列的内容的大小(长度)时,每行的其他两列的高度不会动态调整。我对如何解决这个问题很困惑?下面给出了我创建的下拉列表的图像,其中行的未调整高度。
这是codepen页面的链接,其中包含示例和我使用过的代码:Codepen Dropdown link。我试图通过在CSS文件中使用display:table-cell;
来解决这个问题,但我的努力是徒劳的。请建议如何解决此问题。此外。这是我想要的输出。
下面给出的是代码片段。
$(function() {
$.widget("custom.mySelectMenu", $.ui.selectmenu, {
_renderMenu: function(ul, items) {
var that = this,
currentCategory = "";
$.each(items, function(index, item) {
var li, name, short, price;
if (item.optgroup != currentCategory) {
ul.append(
"<li class='ui-selectmenu-category'>" +
item.optgroup +
"</li>"
);
currentCategory = item.optgroup;
}
li = that._renderItemData(ul, item);
console.log(ul);
name = li.text();
short = item.element.data("short");
price = item.element.data("price");
console.log(li, short, price);
li.prepend(
$("<span>", {
class: "short"
}).html(short)
);
li.append(
$("<span>", {
class: "price"
}).html(price)
);
if (item.optgroup) {
li.attr("aria-label", item.optgroup + " : " + item.label);
}
});
}
});
$("#options").mySelectMenu({
width: 300
});
$("#options")
.mySelectMenu("menuWidget")
.addClass("overflow");
});

答案
你可以使用display:table
和display:table-cell
$(function() {
$.widget("custom.mySelectMenu", $.ui.selectmenu, {
_renderMenu: function(ul, items) {
var that = this,
currentCategory = "";
$.each(items, function(index, item) {
var li, name, short, price;
if (item.optgroup != currentCategory) {
ul.append(
"<li class='ui-selectmenu-category'>" +
item.optgroup +
"</li>"
);
currentCategory = item.optgroup;
}
li = that._renderItemData(ul, item);
console.log(ul);
name = li.text();
short = item.element.data("short");
price = item.element.data("price");
console.log(li, short, price);
li.prepend(
$("<span>", {
class: "short"
}).html(short)
);
li.append(
$("<span>", {
class: "price"
}).html(price)
);
if (item.optgroup) {
li.attr("aria-label", item.optgroup + " : " + item.label);
}
});
}
});
$("#options").mySelectMenu({
width: 300
});
$("#options")
.mySelectMenu("menuWidget")
.addClass("overflow");
});
.ui-menu .ui-menu-item {
display:table; width:100%;

另一答案
Very simple fix, add this:
.ui-menu .ui-menu-item:not(.ui-selectmenu-category) {
display: flex;
}
另一答案
根据你的代码添加这个display: flex;
.ui-menu .ui-menu-item {
display: flex;
height: auto;
flex-direction: row;
margin: 0;
cursor: pointer;
list-style-image:
}
