How can I add "src" in iframe attribute ( iframe src=" "
) to getElementById ( document.getElementById(" ").innerHTML = replaceurl
)?
<div class="output"> <iframe src="" style="width: 640px; height: 480px;"></iframe> </div> <script> function myFunction() { var geturl = document.getElementById("url").value; var replaceurl = ("https://docs.google.com/gview?url=" + geturl + "&embedded=true"); document.getElementById("").innerHTML = replaceurl; } </script>
You must use the setAttribute
method for this ( https://developer.mozilla.org/de/docs/Web/API/Element/setAttribute ).
In your case, it can be done by writing the following:
// HTML
<iframe id="your-iframe" src="" style="width: 640px; height: 480px;"></iframe>
// JS
document.getElementById("your-iframe").setAttribute('src', replaceurl);
why not trying to add an id to the iframe element and pass urls to it by calling your function? like this:
<div class="output">
<iframe src="" id="myIframe" style="width: 640px; height: 480px;"></iframe>
</div>
<script>
function myFunction(id) {
var geturl = document.getElementById("url").value;
var replaceurl = ("https://docs.google.com/gview?url=" + geturl + "&embedded=true");
document.getElementById(id).src = replaceurl;
}
//call your function.
myFunction("myIframe");
</script>
You can set the src
of the <iframe>
by directly assigning the new URL to the src
property.
function myFunction() { const geturl = document.getElementById("url").value, replaceurl = `https://docs.google.com/gview?url=${geturl}&embedded=true`; document.querySelector('.output iframe').src = replaceurl; } myFunction();
<input type="text" id="url" value="https://stackoverflow.com/" /> <div class="output"> <iframe style="width: 640px; height: 480px;"></iframe> </div>
