我是Java语言的新手，找不到我的问题的答案。如果您单击5次按钮，我的JavaScript是否有可能查看div？如果是这种情况，我怎样才能做到这一点？
谢谢！
没有jQuery：
document.addEventListener("DOMContentLoaded", function(event) {
var button = document.getElementById('click_me');
var elem = document.getElementById('message');
var count = 0;
button.addEventListener('click', function(e) {
e.preventDefault();
count++;
if(count == 5){
elem.style.display = 'block';
}
}, false);
});#message {
background: #0f0;
display: none;
padding: 10px;
}<button type="button" id="click_me">Click Me</button>
<div id="message">Hello World</div>使用jQuery：
$(function() {
var count = 0;
$('#click_me').click(function(e) {
e.preventDefault();
count++;
if(count == 5) {
$('#message').show();
}
});
});#message {
background: #0f0;
display: none;
padding: 10px;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button type="button" id="click_me">Click Me</button>
<div id="message">Hello World</div>var clicks = 0;
function myFunction() {
clicks = clicks+1;
if(clicks == 5){
document.getElementById('target').style.display = 'block';
}
}<button onclick="myFunction()">Click me</button>
<div style="display:none;" id="target">You clicked 5 times</div>您需要这样吗？
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>
<script>
$(document).ready(function(){
n=1;
$(".clickable").click(function(){
if(n==5){
alert("You clicked 5 times");
}else{
n++;
}
});
});
</script>
</head>
<body>
<button class="clickable">Click here 5 times</button>
</body>
</html>
