We can parse a URL(Uniform Resource Locator) to access its component and this can be achieved using predefined properties in JavaScript. For Example, the first example parses the URL of the current web page and the second example parses a predefined URL.
Example 1:This example parses the URL of the current web page.
HTML
< body style = "text-align:center;" >
< h2 style = "color:green;" >
Required URL is:
</ h2 >
< p id = "para1" ></ p >
< button onclick = "my_function()" >
Parse It
</ button >
< p id = "para2" ></ p >
< p id = "para3" ></ p >
< script >
document.getElementById("para1")
.innerHTML = window.location.href;
function my_function() {
document.getElementById("para2")
.innerHTML =
`< h3 style = "color:green;" >Hostname : </ h3 >` +
window.location.hostname;
document.getElementById("para3")
.innerHTML =
`< h3 style = "color:green;" >Path : </ h3 >` +
window.location.pathname;
}
</ script >
</ body >
|
Output:
Parse a URL into hostname and path
Example 2 This example parses the predefined URL.
HTML
< body style = "text-align: center;" >
< h2 style = "color: green;" >
Required URL is:
</ h2 >
< p id = "para1" ></ p >
< button onclick = "my_function()" >
Parse It
</ button >
< p id = "para2" ></ p >
< p id = "para3" ></ p >
< script >
var my_url = new URL(
document.getElementById("para1")
.innerHTML = my_url;
function my_function() {
document.getElementById("para2")
.innerHTML =
`< h3 style = "color:green;" >Hostname : </ h3 >`
+ my_url.hostname;
document.getElementById("para3")
.innerHTML =
`< h3 style = "color:green;" >Path : </ h3 >`
+ my_url.pathname;
}
</ script >
</ body >
