I am looking for a way to call a javascript number in the body of an html page. This does not have to be long and extravagant just simply work, I just want something like:
<html>
<head>
<script type="text/javscript">
var number = 123;
</script>
</head>
<body>
<h1>"the value for number is: " + number</h1>
</body>
</html>
Try This...
<html>
<head>
<script>
function myFunction() {
var number = "123";
document.getElementById("myText").innerHTML = number;
}
</script>
</head>
<body onload="myFunction()">
<h1>"The value for number is: " <span id="myText"></span></h1>
</body>
</html>Use document.write().
<html>
<head>
<script type="text/javascript">
var number = 123;
</script>
</head>
<body>
<h1>
the value for number is:
<script type="text/javascript">
document.write(number)
</script>
</h1>
</body>
</html>
<html>
<head>
<script type="text/javascript">
var number = 123;
var string = "abcd";
function docWrite(variable) {
document.write(variable);
}
</script>
</head>
<body>
<h1>the value for number is: <script>docWrite(number)</script></h1>
<h2>the text is: <script>docWrite(string)</script> </h2>
</body>
</html>
You can shorten document.write but
can't avoid <script> tag
Use the document.write() method to dynamically write content to the HTML document.
<h1><script>document.write("the value for number is: " + number)</script></h1>
Make sure that the variable number is declared and has a value before this script is executed.
You can do the same on document ready event like below
<script>
$(document).ready(function(){
var number = 112;
$("yourClass/Element/id...").html(number);
// $("yourClass/Element/id...").text(number);
});
</script>
or you can simply do it using document.write(number);.
Here is another way it can be done .
function showData(m)
{
let x ="<div> added from js ";
let y = m.toString();
let z = "</div>";
let htmlData = x+y+z ;
content.insertAdjacentHTML("beforeend",htmlData);
}
<script type="text/javascript">
function get_param(param) {
var search = window.location.search.substring(1);
var compareKeyValuePair = function(pair) {
var key_value = pair.split('=');
var decodedKey = decodeURIComponent(key_value[0]);
var decodedValue = decodeURIComponent(key_value[1]);
if(decodedKey == param) return decodedValue;
return null;
};
var comparisonResult = null;
if(search.indexOf('&') > -1) {
var params = search.split('&');
for(var i = 0; i < params.length; i++) {
comparisonResult = compareKeyValuePair(params[i]);
if(comparisonResult !== null) {
break;
}
}
} else {
comparisonResult = compareKeyValuePair(search);
}
return comparisonResult;
}
var parcelNumber = get_param('parcelNumber'); //abc
var registryId = get_param('registryId'); //abc
var registrySectionId = get_param('registrySectionId'); //abc
var apartmentNumber = get_param('apartmentNumber'); //abc
</script>then in the page i call the values like so:
<td class="tinfodd"> <script type="text/javascript">
document.write(registrySectionId)
</script></td>Index.html:
<html>
<body>
Javascript Version: <b id="version"></b>
<script src="app.js"></script>
</body>
</html>
app.js:
var ver="1.1";
document.getElementById("version").innerHTML = ver;
<?php
$x1='<span id="x1"></span><script>document.getElementById("x1").innerHTML = x1;</script>';
$x2='<span id="x2"></span><script>document.getElementById("x2").innerHTML = x2;</script>';
$x3='<span id="x3"</span><script>document.getElementById("x3").innerHTML = x3;</script>';
?>
<html><body>
<script> var
x1="123",
x2="ABC",
x3=666;
</script>
<?php echo $x1 ?><br>
<?php echo $x2 ?><be>
<?php echo $x3 ?><be>
</body></html>
You cannot add JavaScript variable to HTML code.
For this you need to do in following way.
<html>
<head>
<script type="text/javscript">
var number = 123;
document.addEventListener('DOMContentLoaded', function() {
document.getElementByTagName("h1").innerHTML("the value for number is: " + number);
});
</script>
</head>
<body>
<h1></h1>
</body>
</html>
