Is it possible to call a javascript function from the URL? I am basically trying to leverage JS methods in a page I don't have access to the source.
Something like: http://www.example.com/mypage.aspx?javascript:printHelloWorld()
I know if you put javascript:alert("Hello World");
into the address bar it will work.
I suspect the answer to this is no but, just wondered if there was a way to do it.
This question is related to
javascript
url
About the window.location.hash
property:
Return the anchor part of a URL.
//Assume that the current URL is
var URL = "http://www.example.com/test.htm#part2";
var x = window.location.hash;
//The result of x will be:
x = "#part2"
Exmaple 2:
$(function(){
setTimeout(function(){
var id = document.location.hash;
$(id).click().blur();
}, 200);
})
Example 3:
var hash = "#search" || window.location.hash;
window.location.hash = hash;
switch(hash){
case "#search":
selectPanel("pnlSearch");
break;
case "#advsearch":
case "#admin":
}
you may also place the followinng
<a href='javascript:alert("hello world!");'>Click me</a>
to your html-code, and when you click on 'Click me' hyperlink, javascript will appear in url-bar and Alert dialog will show
/test.html#alert('heello')
test.html
<button onClick="eval(document.location.hash.substring(1))">do it</button>
Write in address bar
javascript:alert("hi");
Make sure you write in the beginning: javascript:
You can use Data URIs.
For example:
data:text/html,<script>alert('hi');</script>
For more information visit: https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs
you can execute javascript from url via events
Ex: www.something.com/home/save?id=12<body onload="alert(1)"></body>
does work if params in url are there.
you can use like this situation:
for example, you have a page: http://www.example.com/page.php
then in that page.php, insert this code:
if (!empty($_GET['doaction']) && $_GET['doaction'] == blabla ){
echo '<script>alert("hello");</script>';
}
then, whenever you visit this url: http://www.example.com/page.php?doaction=blabla
then the alert will be automatically called.
Using Eddy's answer worked very well as I had kind of the same problem. Just call your url with the parameters : "www.mypage.html#myAnchor"
Then, in mypage.html :
$(document).ready(function(){
var hash = window.location.hash;
if(hash.length > 0){
// your action with the hash
}
});
