This article illustrates the use of the height() method in jQuery as an example. Share with you for your reference. The specific analysis is as follows:
This method gets or sets the height value of the matching element, with the default unit being px.
Grammatical structure 1:
$(selector).height()
Returns the current height of the first matched element with no arguments.
Example code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="author" content="//www.ofstack.com/" />
<title> The home of the script </title>
<style type="text/css">
div{
height:150px;
width:150px;
background-color:green;
margin-top:10px;
}
</style>
<script type="text/javascript" src="mytest/jQuery/jquery-1.8.3.js"></script>
<script type="text/javascript">
$(document).ready(function(){
alert($("div").height());
})
</script>
</head>
<body>
<div></div>
</body>
</html>
Grammatical structure 2:
$(selector).height(val)
The default unit is px. You can also use other units such as em or percentages.
Example code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="author" content="//www.ofstack.com/" />
<title> The home of the script </title>
<style type="text/css">
div{
height:150px;
width:150px;
background-color:green;
margin-top:10px;
}
</style>
<script type="text/javascript" src="mytest/jQuery/jquery-1.8.3.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("button").click(function(){
$("div").height("200px")
})
})
</script>
</head>
<body>
<div></div>
<button> Click to view </button>
</body>
</html>
