Anchor Text Example
using JavaScript, how do i get a link out of selected text?
I would like to know how to get the URL of a selected hyperlink to be display in a msgbox using javascript.
Best example i can give is you have a list of links on a webpage and a single button with the function i need attached, you highlight/select text on one link, and click a button on the page, the JavaScript creates an Alertbox and tells you what the URL is.
The links on the list are anchor tags surrounding a descriptive term for example function ExtractURLs () { // If re is corrupted: var re = /(ht|f)tp(s?)://[0-9a-zA-Z]([-.w]*[0-9a-zA-Z])*(:(0-9)*)*(/?)([a-zA-Z0-9-.?,'/\+&%$#_]*)?/g;
// Then uncomment these lines and stick them together without any spaces: // var re = /(ht|f)tp(s?)://[0-9a-zA-Z] // ([-.w]*[0-9a-zA-Z])*(:(0-9)*)* // (/?)([a-zA-Z0-9-. // ?,'/\+&%$#_]*)?/g;
// For example: // A // B // C // makes ABC
var textBox = document.getElementById ("inputText");
var urls
var found = false; var urlText = "";
while ((urls = re.exec (textBox.value)) != null) { found = true; urlText += urls [0] + "n"; }
if (found) { alert ("URLs:n" + urlText); } else { alert ("No URL found."); } }
This simple demo extracts all URLs found in the text area provided below.
