This tutorial explains about how to Parsing URLs within the posted text like Twitter with Javascript. My last post I had included this Script. I was developing project I found this nice javascript prototype property script in mozilla labs site.
If you want to suggest any other alternate scripts, feel free post a comment.
JavaScript
Method String.prototype property invoked parseURL. When called on a String the regular expression finds any case of a URL and will enclose the URL with a HTML anchor tag.
<head>
String.prototype.parseURL = function()
{
return this.replace(/[A-Za-z]+:\/\/[A-Za-z0-9-_]+\.[A-Za-z0-9-_:%&\?\/.=]+/, function(url) {
return url.link(url);
});
};
</head>
String.prototype.parseURL = function()
{
return this.replace(/[A-Za-z]+:\/\/[A-Za-z0-9-_]+\.[A-Za-z0-9-_:%&\?\/.=]+/, function(url) {
return url.link(url);
});
};
</head>
index.php
Here we applying the parseURL() method to text variable called posted update contains a URL. But in database the update does not contain any anchor HTML tag.
<body>
<form action="" method="post">
<span class="what">What are you doing?</span>
<textarea ="" cols="55" id="update" maxlength="145" name="update" rows="3"></textarea>
<input type="submit" value=" Update " class="update_button" />
</form>
<?php
include("dbconfig.php");
$sql="select * from updates order by ms_id desc";
$result = mysql_query($sql);
while($row=mysql_fetch_array($result))
{
$message=stripslashes($row["message"]);
?>
<tr>
<td>
//---------------------------------------------------------------
<script type="text/javascript">
var test = "<?php echo $message; ?>";// Variable text = Updates from the database
document.write(test.parseURL());
</script>
//---------------------------------------------------------------
</td><td>
<a href="#" id="<?php echo $row["ms_id"]; ?>" class="delbutton"><img src="trash.png" alt="delete"/></a> </td></tr>
<?php
}
?>
</body>
