我想根据点击的按钮显示/隐藏div。我尝试使用javascript函数的参数进行此操作,但我猜测我做错了所以请帮忙。
这是我的HTML:
<div id="div1">
Content of div1</div>
<div id="div2">
Content of div2</div>
<button id="button" onclick="showhide(x)">Toggle div1</button>
<button id="button" onclick="showhide(y)">Toggle div2</button>
这就是我迄今为止所做的,JS-wise:
<script>
function showhide(x,y)
{
var div x = "div1";
var div y = "div2";
var div = document.getElementById(x);
var div = document.getElementById(y);
if (div.style.display !== "none") {
div.style.display = "none";
}
else {
div.style.display = "block";
}
}
</script>

你有一个javascript函数,它有2个参数,在你的HTML中你只发送1。 你能做的是以下几点:
在按钮上的HTML onclick:
<button id="button" onclick="showhide('div1')">Toggle div1</button>
<button id="button" onclick="showhide('div2')">Toggle div2</button>
javascript函数只需要1个参数:
function showhide(divElement)
{
var div = document.getElementById(divElement);
if (div.style.display !== "none") {
div.style.display = "none";
}
else {
div.style.display = "block";
}
}

Here is the HTML code :
<div id="div1">
Content of div1
</div>
<div id="div2">
Content of div2
</div>
<button id="button" onclick="showhide('div1')">Toggle div1</button>
<button id="button" onclick="showhide('div2')">Toggle div2</button>
Here is the javascript code :
<script type="text/javascript" >
function showhide(toggleID){
var toggleDiv = document.getElementById(toggleID);
if(toggleDiv.style.display != "none"){
toggleDiv.style.display = 'none';
}else{
toggleDiv.style.display = 'block';
}
}
</script>

这是不对的:
var div x = "div1";
你不能有空间:
var div_x = "div1";
你实际上可以删除这两行并保留它:
function showhide(x,y)
{
var div = document.getElementById(x);
var div2 = document.getElementById(y);
if (div.style.display !== "none") {
div.style.display = "none";
}
else {
div.style.display = "block";
}
if (div2.style.display !== "none") {
div2.style.display = "none";
}
else {
div2.style.display = "block";
}
}
并将其命名为:
showhide("div1", "div2");

像这样使用:
<button id="button" onclick="showhide(x,'')">Toggle div1</button>
<button id="button" onclick="showhide('',y)">Toggle div2</button>
并改变这一点:
var div = document.getElementById(x);
var div = document.getElementById(y);
对此:
var div = document.getElementById(x && y); //if x returns x else y
