jQuery load() method is a simple but very powerful AJAX method. The Load() method in jQuery helps to load data from the server and returned it to the selected element without loading the whole page.
Syntax:
$(selector).load(URL, data, callback);
Parameters: This method accepts three parameters as mentioned above and described below:
- URL: It is used to specify the URL which needs to load.
- data: It is used to specify a set of query key/value pairs to send along with the request.
- callback: It is the optional parameter which is the name of a function to be executed after the load() method is call.
Example 1: The geeks.txt file is stored on the server and it will load after clicking the click button. The content of geeks.txt are: Hello GeeksforGeeks!
<!DOCTYPE html><html>
<head>
<script src=
</script>
<script>
$(document).ready(function () {
$("button").click(function () {
$("#div_content").load("gfg.txt");
});
});
</script>
<style>
body {
text-align: center;
}
.gfg {
font-size: 40px;
font-weight: bold;
color: green;
}
.geeks {
font-size: 17px;
color: black;
}
#div_content {
font-size: 40px;
font-weight: bold;
color: green;
}
</style>
</head>
<body>
<div id="div_content">
<div class="gfg">
GeeksforGeeks
</div>
<div class="geeks">
A computer science portal for geeks
</div>
</div>
<button>
Change Content
</button>
</body>
</html>
|
Output:
There is also an additional callback function in the parameter which will run when the load() method is completed. This callback function has three different parameters:
- parameter 1: It contains the result of the content if the method call succeeds.
- parameter 2: It contains the status of the call function.
- parameter 3: It contains the XMLHttpRequest object.
Example 2: An alert box will appear after clicking on the button and if the content loaded successfully then it will give a message “Content loaded successfully!”. Otherwise, it will show an error message.
<!DOCTYPE html><html>
<head>
<script src=
</script>
<script>
$(document).ready(function () {
$("button").click(function () {
$("#div_content").load("gfg.txt", function (response,
status, http) {
if (status == "success")
alert("Content loaded successfully!");
if (status == "error")
alert("Error: " + http.status + ": "
+ http.statusText);
});
});
});
