我有一个小问题,我有两组两个按钮,当我按下顶部按钮对时,它们会在按钮下方显示输出java数组文本。在它下面的第二组按钮上,它显示按钮上方的文字,我不知道它为什么这样做。这是代码:
function Timeofday() {
var myArray = new Array("One", "Two", "Three", "Four", );
var random = myArray[Math.floor(Math.random() * myArray.length)];
document.getElementById("zemo").innerHTML = random;
}
function Weather() {
var myArray = new Array("One", "Two", "Three", "Four", );
var random = myArray[Math.floor(Math.random() * myArray.length)];
document.getElementById("temo").innerHTML = random;
}
function GetValue() {
var myArray = new Array("One", "Two", "Three", "Four", );
var random = myArray[Math.floor(Math.random() * myArray.length)];
document.getElementById("remo").innerHTML = random;
}
function getRandomArrayElements(count) {
var arr = ['one', 'two', 'three', 'four'];
var shuffled = arr.slice(0),
i = arr.length,
min = i - count,
temp, index;
while (i-- > min) {
index = Math.floor((i + 1) * Math.random());
temp = shuffled[index];
shuffled[index] = shuffled[i];
shuffled[i] = temp;
}
document.getElementById("demo").innerHTML = shuffled.slice(min);
}
.button {
background-color: #008CBA;
border: none;
color: white;
padding: 15px 32px;
text-align: center;
text-decoration: none;
display: inline-block;
font-size: 16px;
margin: 4px 2px;
cursor: pointer;
top: 50%;
}
.wrapper {
text-align: center;
}
.demo {
text-align: center;
color: #008CBA;
text-transform: uppercase;
font-size: 300%;
}
.remo {
text-align: center;
color: #008CBA;
text-transform: uppercase;
font-size: 300%;
}
.temo {
text-align: center;
color: #4CAF50;
text-transform: uppercase;
font-size: 300%;
}
.zemo {
text-align: center;
color: #4CAF50;
text-transform: uppercase;
font-size: 300%;
}
.buttons {
background-color: #4CAF50;
border: none;
color: white;
padding: 15px 32px;
text-align: center;
text-decoration: none;
display: inline-block;

}
<div class="wrapper">
<input id="btnSearch" class="button" type="button" value="Randomize Subject" onclick="getRandomArrayElements(3);" />
<input id="btnSearch" class="button" type="button" value="Randomize
Restriction" onclick="GetValue();" />
</div>
<p id="demo" class="demo"></p>
<p id="remo" class="remo"></p>
<p id="temo" class="temo"></p>
<p id="zemo" class="zemo"></p>
<div>
<div>
<div>
</div>
</div>
This is where the text displays above the buttons
<div class="wrapper">
<input id="btnSearch" class="buttons" type="button" value="Randomize Time of
Day" onclick="Timeofday();" />
<input id="btnSearch" class="buttons" type="button" value="Randomize
Weather" onclick="Weather();" />
</div>
<div>

原因是HTML文件中元素的顺序。 javascript正在选择<p>
标签并用函数的结果填充它们。 <p>
代码位于第一组按钮下方,位于HTML文件中的第二组按钮上方

因为你总是在temo和zemo上设置innerHTML用于底部按钮,它们位于按钮上方。
如果您想要下面的下一个,只需将这些div移动到第二组按钮下方。如果您正在尝试做其他事情,请编辑您的问题并澄清。
