如何阻止父div内的div换行而不是被切断?
代码:
var slider = document.getElementById("slider"),
cont1 = document.getElementById("container1"),
cont2 = document.getElementById("container2");
slider.addEventListener("input", function() {
cont1.style.width = slider.value + "px";
cont2.style.width = slider.value + "px";
}, false);
#item {
width: 100px;
height: 100px;
float: left;
}
.container {
height: 100px;
background-color: #ccc;
}
<p>use slider to change width of the container</p>
<input id="slider" type="range" max="500">
<p>overflow: hidden</p>
<div class="container" id="container1" style="width: 300px; overflow: hidden;">
<div id="item" style="background-color: red;"></div>
<div id="item" style="background-color: green;"></div>
</div>
<p>overflow: visible</p>
<div class="container" id="container2" style="width: 300px; overflow: visible;">
<div id="item" style="background-color: red;"></div>
<div id="item" style="background-color: green;"></div>
</div>
如您所见,当我更改父div的大小时,将自动换行。搜索之后,我找到了两种解决方案。其中一个要求使用绝对定位的div来设置容器的宽度。另一个使用white-space: none
,但没有运气。

考虑使用inline-block
代替浮动,可以使用with-space
技巧:
var slider = document.getElementById("slider"),
cont1 = document.getElementById("container1"),
cont2 = document.getElementById("container2");
slider.addEventListener("input", function() {
cont1.style.width = slider.value + "px";
cont2.style.width = slider.value + "px";
}, false);
#item {
width: 100px;
height: 100px;
display: inline-block;
}
.container {
height: 100px;
background-color: #ccc;
white-space: nowrap;
font-size: 0; /*to avoid white-space between inline-block*/
}
<p>use slider to change width of the container</p>
<input id="slider" type="range" max="500">
<p>overflow: hidden</p>
<div class="container" id="container1" style="width: 300px; overflow: hidden;">
<div id="item" style="background-color: red;"></div>
<div id="item" style="background-color: green;"></div>
</div>
<p>overflow: visible</p>
<div class="container" id="container2" style="width: 300px; overflow: visible;">
<div id="item" style="background-color: red;"></div>
<div id="item" style="background-color: green;"></div>
</div>

如果我正确理解了您的意图,则希望灰色滑块“淡入”绿色方块,而将绿色方块留在原处。
为此,您需要将overflow: hidden
与position: absolute
结合使用:
var slider = document.getElementById("slider");
var cont1 = document.getElementById("container1");
slider.addEventListener("input", function() {
cont1.style.width = slider.value + "px";
}, false);
#green {
position: absolute;
left: calc(100px + 8px); /* Red offset + body margin */
}
.item {
width: 100px;
height: 100px;
float: left;
}
.container {
height: 100px;
background-color: #ccc;
}
<p>use slider to change width of the container</p>
<input id="slider" type="range" max="500">
<div class="container" id="container1" style="width: 300px; overflow: hidden;">
<div class="item" style="background-color: red;"></div>
<div id="green" class="item" style="background-color: green;"></div>
</div>
请注意,您提供的代码也具有重复的#item
ID,这是无效的标记。在上面的示例中,我将它们更改为类。
