Adding an img element to a div with javascript
JavascriptDomJavascript Problem Overview
I am trying to add an img to the placehere div using JavaScript, however I am having no luck. Can anyone give me a hand with my code?
<html>
<script type="text/javascript">
var elem = document.createElement("img");
elem.setAttribute("src", "images/hydrangeas.jpg");
elem.setAttribute("height", "768");
elem.setAttribute("width", "1024");
elem.setAttribute("alt", "Flower");
document.getElementById("placehere").appendChild("elem");
</script>
<body>
<div id="placehere">
</div>
</body>
</html>
Javascript Solutions
Solution 1 - Javascript
document.getElementById("placehere").appendChild(elem);
not
document.getElementById("placehere").appendChild("elem");
and use the below to set the source
elem.src = 'images/hydrangeas.jpg';
Solution 2 - Javascript
It should be:
document.getElementById("placehere").appendChild(elem);
And place your div before your javascript, because if you don't, the javascript executes before the div exists. Or wait for it to load. So your code looks like this:
window.onload = function() {
var elem = document.createElement("img");
elem.setAttribute("src", "http://img.zohostatic.com/discussions/v1/images/defaultPhoto.png");
elem.setAttribute("height", "768");
elem.setAttribute("width", "1024");
elem.setAttribute("alt", "Flower");
document.getElementById("placehere").appendChild(elem);
}
<div id="placehere"></div>
To prove my point, see this with the onload and this without the onload. Fire up the console and you'll find an error stating that the div doesn't exist or cannot find appendChild method of null.
Solution 3 - Javascript
function image()
{
//dynamically add an image and set its attribute
var img=document.createElement("img");
img.src="p1.jpg"
img.id="picture"
var foo = document.getElementById("fooBar");
foo.appendChild(img);
}
<span id="fooBar"> </span>
Solution 4 - Javascript
The following solution seems to be a much shorter version for that:
<div id="imageDiv"></div>
In Javascript:
document.getElementById('imageDiv').innerHTML = '<img width="100" height="100" src="images/hydrangeas.jpg">';
Solution 5 - Javascript
In case anyone is wondering how to do it with JQuery:
$("<img height='200' width='200' alt='testImage' src='https://avatars.githubusercontent.com/u/47340995?v=4'> </img>").appendTo("#container");
