I am practicing to capture screenshot of webpage by using api.
I want to change the img src, on the button click.
Code is as follows:
<section>
<div class="urldiv">
<label for="Url">Url</label>.
<br>
<input type="text" name="Url"
id="input" value="" />
</div>
<div class="ss">
<img id="sh" src="https://api.screenshotmachine.com?key=c04d3a&url=screenshotmachine.com&dimension=1024x768"/>
</div>
<button onclick="changeimg()">Capture</button>
</section>
And this is JavaScript:
<script type="text/javascript" charset="utf-8">
var url = document.getElementById("input").value;
function changeimg() {
document.getElementById("screenshot").src = "https://api.screenshotmachine.com?key=c04d3a&url=" + url + "&dimension=1024x768";
}
</script>
You should get the input value inside the function and the img id is sh not screenshot
Now it's work
const input = document.getElementById("input");
function changeimg() {
document.getElementById("sh").src = "https://api.screenshotmachine.com?key=c04d3a&url=" + input.value + "&dimension=1024x768";
} <section>
<div class="urldiv">
<label for="Url">Url</label>.
<br>
<input type="text" name="Url" id="input" value="" />
<button onclick="changeimg()">Capture</button>
</div>
<div class="ss">
<img id="sh" src="https://api.screenshotmachine.com?key=c04d3a&url=screenshotmachine.com&dimension=1024x768"/>
</div>
</section>
