[英]Javascript code to count number of clicks on a button
I have a page where i want to count the number of clicks on a button.我有一个页面,我想计算一个按钮的点击次数。 and the numbers are shown just below that button.
数字显示在该按钮的正下方。
I tried to search and found this.我试图搜索并找到了这个。 I think this will not count the total number of clicks: Keeping track of number of button clicks
我认为这不会计算总点击次数: 跟踪按钮点击次数
I am familiar with javascript code, so any help would be useful.我熟悉 javascript 代码,所以任何帮助都会有用。
HTML Code : HTML代码:
<button onclick="myFunction()">Try it</button>
JS Code : JS代码:
var inc=0;
function myFunction() {
inc=inc+1;
alert(inc);
}
Suppose your html is:假设你的 html 是:
<div id="showCount"></div>
<input type="button" id="btnClick" value="Click me" onclick="CountFun();/>
Now the function is:现在的功能是:
<script>
var cnt=0;
function CountFun(){
cnt=parseInt(cnt)+parseInt(1);
var divData=document.getElementById("showCount");
divData.innerHTML="Number of Downloads: ("+cnt +")";//this part has been edited
}
</script>
You can do it this way:你可以这样做:
<script>
var cnt=0;
function CountFun(){
cnt++
var divData=document.getElementById("showCount");
divData.innerHTML="Number of Downloads: ("+cnt +")";//this part has been edited
}
</script>
Or you can add event listner或者您可以添加事件监听器
documet.getElementById('[id of the button]').addEventListener('click', function(){
cnt++
var divData=document.getElementById("showCount");
divData.innerHTML="Number of Downloads: ("+cnt +")";//this part has been edited
});
HTML: HTML:
<button id='click-me'>Click me please!!</button>
<div id='showCount'></div>
JS Code: JS代码:
<script>
let count = 0;
let btn = document.querySelector('#click-me');
let divSection = document.getElementById('showCount');
btn.addEventListener('click', (e)=>{
count++;
divSection.innerHTML=`Number of Clicks are: ${count}`;
});
</script>
