How to remove Special Character and alphabet from variable by jQuery.
I have
var test = +985
But I want to get value as
var another = 985
It should not allow character as well + as I am using it in Phone Code
try to something like this...
var inputString = "~!##$%^&*()_+=`{}[]|\:;'<>,./?Some actual text to keep, maybe...",
var outputString = inputString.replace(/([~!##$%^&*()_+=`{}\[\]\|\\:;'<>,.\/? ])+/g, '-').replace(/^(-)+|(-)+$/g,'');
Might be duplicate of this
You just need to use replace function it's first parameter is symbol you want to replace and another is symbol or word you want to replace with.
For more info please visit Javascript replace function
var test = "+985";
var another = test.replace("+", "");
Try this to extract number:
var test = +985;
alert(test+"".match(/\d+/));

How can i select the fragment after the '#' symbol in my URL using PHP?
The result that i want is "photo45".
This is an example URL:
http://example.com/site/gallery/1#photo45
If you want to get the value after the hash mark or anchor as shown in a user's browser: This isn't possible with "standard" HTTP as this value is never sent to the server (hence it won't be available in $_SERVER["REQUEST_URI"] or similar predefined variables). You would need some sort of JavaScript magic on the client side, e.g. to include this value as a POST parameter.
If it's only about parsing a known URL from whatever source, the answer by mck89 is perfectly fine though.
That part is called "fragment" and you can get it in this way:
$url=parse_url("http://example.com/site/gallery/1#photo45 ");
echo $url["fragment"]; //This variable contains the fragment
A) already have url with #hash in PHP? Easy! Just parse it out !
if( strpos( $url, "#" ) === false ) echo "NO HASH !";
else echo "HASH IS: #".explode( "#", $url )[1]; // arrays are indexed from 0
Or in "old" PHP you must pre-store the exploded to access the array:
$exploded_url = explode( "#", $url ); $exploded_url[1];
B) You want to get a #hash by sending a form to PHP? => Use some JavaScript MAGIC! (To pre-process the form)
var forms = document.getElementsByTagName('form'); //get all forms on the site
for (var i = 0; i < forms.length; i++) { //to each form...
forms[i].addEventListener( // add a "listener"
'submit', // for an on-submit "event"
function () { //add a submit pre-processing function:
var input_name = "fragment"; // name form will use to send the fragment
// Try search whether we already done this or not
// in current form, find every <input ... name="fragment" ...>
var hiddens = form.querySelectorAll('[name="' + input_name + '"]');
if (hiddens.length < 1) { // if not there yet
//create an extra input element
var hidden = document.createElement("input");
//set it to hidden so it doesn't break view
hidden.setAttribute('type', 'hidden');
//set a name to get by it in PHP
hidden.setAttribute('name', input_name);
this.appendChild(hidden); //append it to the current form
} else {
var hidden = hiddens[0]; // use an existing one if already there
}
//set a value of #HASH - EVERY TIME, so we get the MOST RECENT #hash :)
hidden.setAttribute('value', window.location.hash);
}
);
}
Depending on your form's method attribute you get this hash in PHP by:
$_GET['fragment'] or $_POST['fragment']
Possible returns: 1. ""[empty string] (no hash) 2. whole hash INCLUDING the #[hash] sign (because we've used the window.location.hash in JavaScript which just works that way :) )
C) You want to get the #hash in PHP JUST from requested URL?
YOU CAN'T !
...(not while considering regular HTTP requests)...
...Hope this helped :)
I've been searching for a workaround for this for a bit - and the only thing I have found is to use URL rewrites to read the "anchor". I found in the apache docs here http://httpd.apache.org/docs/2.2/rewrite/advanced.html the following...
By default, redirecting to an HTML anchor doesn't work, because mod_rewrite escapes the # character, turning it into %23.
This, in turn, breaks the redirection.
Solution: Use the [NE] flag on the RewriteRule. NE stands for No
Escape.
Discussion: This technique will of course also work with other special
characters that mod_rewrite, by default, URL-encodes.
It may have other caveats and what not ... but I think that at least doing something with the # on the server is possible.
You can't get the text after the hash mark. It is not sent to the server in a request.
I found this trick if you insist want the value with PHP.
split the anchor (#) value and get it with JavaScript, then store as cookie, after that get the cookie value with PHP
If you are wanting to dynamically grab the hash from URL, this should work:
https://stackoverflow.com/a/57368072/2062851
<script>
var hash = window.location.hash, //get the hash from url
cleanhash = hash.replace("#", ""); //remove the #
//alert(cleanhash);
</script>
<?php
$hash = "<script>document.writeln(cleanhash);</script>";
echo $hash;
?>
You can do it by a combination of javascript and php:
<div id="cont"></div>
And by the other side;
<script>
var h = window.location.hash;
var h1 = (win.substr(1));//string with no #
var q1 = '<input type="text" id="hash" name="hash" value="'+h1+'">';
setInterval(function(){
if(win1!="")
{
document.querySelector('#cont').innerHTML = q1;
} else alert("Something went wrong")
},1000);
</script>
Then, on form submit you can retrieve the value via $_POST['hash'] (set the form)
You need to parse the url first, so it goes like this:
$url = "https://www.example.com/profile#picture";
$fragment = parse_url($url,PHP_URL_FRAGMENT); //this variable holds the value - 'picture'
If you need to parse the actual url of the current browser, you need to request to call the server.
$url = $_SERVER["REQUEST_URI"];
$fragment = parse_url($url,PHP_URL_FRAGMENT); //this variable holds the value - 'picture'
Getting the data after the hashmark in a query string is simple. Here is an example used for when a client accesses a glossary of terms from a book. It takes the name anchor delivered (#tesla), and delivers the client to that term and highlights the term and its description in blue so its easy to see.
setup your strings with a div id, so the name anchor goes where its supposed to and the JavaScript can change the text colors
<div id="tesla">Tesla</div>
<div id="tesla1">An energy company</div>
Use JavaScript to do the heavy work, on the server side, inserted in your PHP page, or wherever..
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
I am launching the Java function automatically when the page is loaded.
<script>
$( document ).ready(function() {
get the anchor (#tesla) from the URL received by the server
var myhash1 = $(location).attr('hash'); //myhash1 == #tesla
trim the hash sign off of it
myhash1 = myhash1.substr(1) //myhash1 == tesla
I need to highlight the term and the description so I create a new var
var myhash2 = '1';
myhash2 = myhash1.concat(myhash2); //myhash2 == tesla1
Now I can manipulate the text color for the term and description
var elem = document.getElementById(myhash1);
elem.style.color = 'blue';
elem = document.getElementById(myhash2);
elem.style.color = 'blue';
});
</script>
This works. client clicks link on client side (example.com#tesla) and goes right to the term. the term and the description are highlighted in blue by JavaScript for quick reading .. all other entries left in black..

Ok i have one maybe stupid question
On my website i have search options, that is input with GET metod, but when someone enter long seperated word like
I AM SOMETIMES BLANK
i got this in my url
http://www.example.com/search.php?page=1&txtPretraga=I%AM%SOMETIMES%BLANK
I dont know how to change that?
I want clean URL like this
http://www.example.com/search.php?page=1&txtPretraga=I-AM-SOMETIMES-BLANK
I want to change % with - in my ULR
Any ideas?
You can use str_replace in your php code:
http://php.net/manual/en/function.str-replace.php
$search_qry = "Whatever%They%Type";
$replace = str_replace($search_qry, "%", "-");
EDIT:
In the case of your strings - they have spaces, which show up as % in a URL, so use this before you do your $_GET
$search_qry = "Whatever They Type";
$replace = str_replace($search_qry, " ", "-");
EDIT 2
Since this is a $_GET - Javascript will have to be used to clean the string before it's sent. (using jQuery and javascript here)
<script type = "text/javascript">
$(document).ready(function(){
$('.example-input').blur(function(){
var str = $(this).val();
var clean_str = str.replace(" ", "-");
$(this).val(clean_str);
});
});
</script>
This should clean the string in the input box before it's even sent through the get.
or instead of .blur, you can use $('submit-button').click(function(){...
Or, you can use the .htaccess file to do a mod rewrite. But I don't know that well enough.
Ok, i got the fix for the problem :)
This is not question for PHP, it is for Javascript and i wrote this function
<script type="text/javascript">
function provera() {
var x=document.forms["hsearch"]["txtPretraga"].value;
var n=str.replace(" ","-");
}
</script>
I have a problem with a word count using the jQuery. The method is working as soon as I click space it will stop.
HTML:
<textarea id="essay_content_area" name="essay_content" onkeydown="words();"></textarea>
<td>Number of words: <div id="othman"></div></td>
jQuery:
function words(content)
{
var f = $("#essay_content_area").val()
$('#othman').load('wordcount.php?content='+f);
}
PHP file:
if(isset($_GET['content']))
{
echo $_GET['content']; // if it works I will send this variable to a function to calculate the words
}
the script shows the content until I click space. any suggestions ?
You need to url-encode the value before sending it over to your PHP script as the value of a GET parameter. Consider this:
function words(content)
{
var f = $("#essay_content_area").val()
$('#othman').load('wordcount.php?content=' + encodeURIComponent(f));
}
You don't need php to count the words you can use JS, something like this:
function words(content)
{
// Get number of words.
var words = content.split(" ").length;
}
You need to url encode your variable before you send it (space is not a valid url character):
function words(content)
{
var f = encodeURIComponent($("#essay_content_area").val());
$('#othman').load('wordcount.php?content='+f);
}
I am trying to separate and reassign values in a variable. What I have is
#&first=1&second=2
can anyone help with a script that will separate and assign this values to another variable so it would be like
var first= val.(first);
var second= val.(second);
I am new to jquery so I am not even sure if I am using the correct syntax.
Thanks
You could do something like this:
var val = "#&first=1&second=2";
var first = gup(val, "first");
var second = gup(val, "second");
function gup(str, name) {
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regexS = "[\\?&]" + name + "=([^&#]*)";
var regex = new RegExp(regexS);
var results = regex.exec(str);
if (results == null) return "";
else return results[1];
}
Checkout the example on jsfiddle: http://jsfiddle.net/WxnJq/
Here's the one that breaks down the GET variables in to key/value pairs, which I believe is what you're after: http://snipplr.com/view/12208/javascript-url-parser/
Also, you can take a look at parseURI, a javascript function that can dissect a URL with GET parameters and grab sections.
Sorry for being quick to post, I thought I found the right function the first time.
JQuery has no builtin way of dealing with querystrings, so I use a plugin for this. You can get it here, works great.
