I am trying to make HTML print out "Germany" when you click the button. But it is not working correctly. Is there something wrong in my code?
HTML
<input type="button" value="click!" onclick="shuffle();"/>
<div id="output"></div>
Javascript
(function(){
window.onload = function(){
alert("welcome to my trip record");
}
})();
var shuffle = function(){
var target = document.getElementById("output");
target.innerHTML = "Germany";
}
Remove the ;
from your onclick
<input type="button" value="click!" onclick="shuffle()"/>
Try to use addEventListener for make event on button click
document.getElementById("myBtn").addEventListener("click", function(){
var target = document.getElementById("output");
target.innerHTML = "Germany";
});
here is the working jsfiddle: https://jsfiddle.net/jxjpzvvz/
<button id='btn_click' type="button">Click me!</button>
<div id="output"></div>
use button element for buttons, not input type button. we are not in the time of html 4.0 ;)
(function(){
window.onload = function(){
alert("welcome to my trip record");
}
})();
var shuffle = function(event){
var target = document.getElementById("output");
target.innerHTML = "Germany";
}
document.getElementById('btn_click').addEventListener('click', shuffle);
i'm fan of no js in the html tags directly, so i add a listener to the element
You made two mistakes First mistake <input />
this is nothing. Second most common "function ();", the ";" Is wrong
Your corrected code
(function(){ window.onload = function(){ alert("welcome to my trip record"); } })(); var shuffle = function(){ var target = document.getElementById("output"); target.innerHTML = "Germany"; }
<input type="button" value="click!" onclick="shuffle()"/> <div id="output"></div>
I like to use DOM EventListener
window.onload = function(){ alert("welcome to my trip record"); } document.getElementById("myBtn").addEventListener("click", function_t); function function_t(){ var target = document.getElementById("output"); target.innerHTML = "Germany"; }
<input type="button" value="click!" id = "myBtn" > <div id="output"></div>
